Great minds answering life's biggest questions

What makes a life good or worth living?
Pythagoreanism
Pythagoras
570 BCE - 495 BCE
To live a good life according to Pythagoras, one should focus on the harmony of the soul and the pursuit of wisdom. Embrace metempsychosis, the belief in the soul's immortality and reincarnation, by living virtuously and practicing self-mastery. Cultivate a balanced lifestyle through moderation, avoiding excesses like meat consumption, which aligns with Pythagorean dietary restrictions. Engage in intellectual pursuits, such as mathematics and contemplation, to understand the universe's harmony. Avoid actions that disrupt this harmony, like violence or injustice, as they lead to disharmony in the soul. By adhering to these principles, one can achieve a harmonious existence and a favorable reincarnation, ultimately leading to happiness and a good life.
Challenge
Heraclitus
Heraclitus criticized Pythagoras for what he perceived as a superficial accumulation of knowledge without true understanding. He mocked Pythagoras as a clever charlatan, suggesting that wisdom is not merely about collecting information but involves deeper insight into the nature of reality. Heraclitus' emphasis on change and the unity of opposites contrasts with Pythagorean ideas of fixed mathematical truths.
Xenophanes
Xenophanes was skeptical of Pythagoras' belief in reincarnation, mocking the idea that the soul could transition into new bodies. He questioned the plausibility of such metaphysical claims, favoring a more rational and empirical approach to understanding the soul and its existence. Xenophanes' critique reflects a broader skepticism among some philosophers regarding Pythagorean mystical beliefs.
Build Upon
Plato
Plato was significantly influenced by Pythagorean ideas, particularly the concept of the soul's immortality and reincarnation. In his works, Plato expanded on these ideas, integrating them into his theory of Forms and the notion that the soul is eternal and seeks knowledge of the true reality. This philosophical development was crucial in shaping Western thought on the soul and its nature.
Aristotle
Aristotle, while diverging from Pythagorean mysticism, adopted the idea of living a harmonious life through virtue. He developed the concept of eudaimonia, or flourishing, which involves living in accordance with virtue and reason. Aristotle's ethical framework, although more grounded in practical reality, reflects the Pythagorean pursuit of a balanced and harmonious life.
Ionian / Flux and Logos
Heraclitus
540 BCE - 480 BCE
Heraclitus advises embracing the constant change inherent in life, encapsulated in his doctrine of "universal flux." To live a good life, one should cultivate awareness of the "unity of opposites," recognizing that apparent contradictions are part of a harmonious whole. Practically, this means accepting life's uncertainties and adapting to new circumstances with resilience. Heraclitus emphasizes the importance of aligning with the "Logos," the rational order of the cosmos, suggesting that understanding and living in accordance with this cosmic reason leads to wisdom and fulfillment. Avoid clinging to permanence or resisting change, as this leads to frustration and discord. By acknowledging the dynamic nature of existence and seeking harmony within it, one can achieve a balanced and contented life.
Challenge
Aristotle
Aristotle challenged Heraclitus's idea of constant change by emphasizing the importance of stability and the potential for achieving a virtuous character through habituation. While acknowledging change, Aristotle argued that a good life is achieved through cultivating virtues, which are stable traits developed through practice and reason. This contrasts with Heraclitus's view, suggesting that ethical living requires a balance between change and stability.
Parmenides
Parmenides directly challenged Heraclitus's view of constant change by proposing that reality is unchanging and that change is an illusion. He argued that true knowledge comes from understanding the eternal and unchanging nature of being, rather than the deceptive appearances of change. This philosophical stance presents a stark contrast to Heraclitus's belief in perpetual flux, suggesting that reality is stable and permanent.
Build Upon
Plato
Plato interpreted Heraclitus's idea of constant flux to mean that the sensory world is always changing and thus unreliable. He built upon this by proposing the existence of eternal Forms or Ideas, which are unchanging and represent true reality. This philosophical framework suggests that a meaningful life involves understanding and aligning oneself with these eternal truths, rather than the transient sensory experiences.
Stoics
The Stoics were heavily influenced by Heraclitus's idea of Logos, which they interpreted as a rational principle governing the universe. They built upon this by developing a philosophy that emphasized living in accordance with nature and reason. For the Stoics, happiness and a meaningful life are achieved by understanding the rational order of the cosmos and aligning one's actions with it, thus embracing change and accepting the flow of life.
Sophism
Protagoras
490 BCE - 420 BCE
Protagoras, a prominent sophist, advocated for a relativistic approach to living a good life, encapsulated in his famous dictum "Man is the measure of all things." To be happy and live well, one should embrace subjectivity, recognizing that truth and morality are relative to individual perception and experience. This means actively engaging in self-reflection to understand personal values and beliefs, and making choices aligned with them. Cultivate skills in rhetoric and critical thinking to navigate societal norms and articulate personal truths effectively. Avoid rigid adherence to absolute truths or external moral dictates, as these can lead to conflict and dissatisfaction. By acknowledging the fluidity of knowledge and ethics, individuals can adapt to changing circumstances and find fulfillment in personal growth and authentic expression.
Challenge
Plato
Plato challenges Protagoras' relativism in his dialogues, particularly in 'Theaetetus'. He argues for the existence of objective truths, which are independent of individual perceptions. Plato believed that truth is not subjective but rather an objective reality that can be apprehended through reason and philosophical inquiry. This is in direct opposition to Protagoras' claim that truth is relative to each individual's perception.
Socrates
Socrates, as depicted in Plato's dialogues, challenges Protagoras' views on the teachability of virtue and the relativistic approach to truth. Socrates argues that virtue is a form of knowledge and can be taught, contrary to Protagoras' relativistic stance that virtue might be subjective. Socrates' method of dialectical questioning aimed to uncover objective truths about virtue and the good life, which he believed were universal and not subject to individual interpretation.
Democritus
Democritus, who is said to have taught Protagoras, criticized the 'Man is the measure of all things' thesis for being self-refuting. Democritus believed in a more objective understanding of reality, grounded in the atomic theory, where reality is composed of indivisible atoms and void. This view contrasts with Protagoras' relativism, which suggests that reality is constructed by individual perceptions.
Build Upon
Aristotle
Aristotle builds upon Protagoras' emphasis on rhetoric and human subjectivity by developing his own theories of rhetoric and ethics. While Aristotle disagrees with the relativistic implications of Protagoras' ideas, he acknowledges the importance of rhetoric in shaping human beliefs and values. Aristotle's 'Rhetoric' explores how persuasion can be used ethically to achieve truth and understanding, reflecting a more structured approach to the subjective elements of human interaction that Protagoras highlighted.
Socratic method / Ethics
Socrates
469 BCE - 399 BCE
Socrates advocates for living a good life through the pursuit of virtue and self-knowledge, emphasizing the importance of philosophical inquiry. To achieve eudaimonia, or true happiness, one must engage in self-examination, as encapsulated in his famous dictum, "Know thyself." This involves understanding one's desires, limitations, and values, and aligning actions with these insights. Socrates warns against the pursuit of material wealth and bodily pleasures, which he views as ultimately unsatisfying. Instead, he encourages focusing on the soul and cultivating inner qualities such as wisdom, justice, and temperance. By harmonizing desires and prioritizing moral excellence, individuals can attain a state of tranquility and fulfillment. Socrates' teachings suggest that a life of virtue, guided by reason and ethical conduct, leads to authentic happiness and a meaningful existence.
Challenge
Epicurus
Epicurus challenged Socratic ideas by arguing that pleasure is the highest good and the key to happiness. He believed that a good life is achieved through the pursuit of simple pleasures and the avoidance of pain, contrasting with Socrates' focus on virtue and philosophical inquiry. Epicurus emphasized the importance of mental pleasures over physical ones, suggesting that tranquility and freedom from fear lead to a happy life, thus offering a different perspective on what constitutes a good life.
Diogenes
Diogenes, a prominent figure in the Cynic school, challenged Socratic ideas by rejecting societal norms and advocating for a life of asceticism and self-sufficiency. He believed that virtue is the only good and that societal conventions are distractions from living a truly virtuous life. Diogenes famously lived in a barrel and practiced shamelessness, emphasizing the importance of living according to nature rather than societal expectations, thus presenting a radical departure from Socratic thought on communal harmony.
Build Upon
Plato
Plato, a student of Socrates, expanded on Socratic ideas by developing the theory of Forms, which posits that true knowledge and the good life are achieved by understanding the eternal and unchanging Forms. In his work 'The Republic,' Plato emphasizes the importance of justice and the philosopher-king, suggesting that a life aligned with the Forms leads to true happiness. Plato's dialogues often feature Socrates as a central character, illustrating the pursuit of wisdom and virtue as the path to a good life.
Aristotle
Aristotle, a student of Plato, further developed the concept of the good life through his idea of eudaimonia, which he defined as flourishing through virtuous activity. While agreeing with Socrates on the importance of virtue, Aristotle introduced the notion of the 'Golden Mean,' advocating for balance and moderation in virtues. He believed that happiness is achieved through rational activity and fulfilling one's potential, thus building upon Socratic ideas by providing a more practical framework for living a virtuous life.
Cyrenaicism (hedonism)
Aristippus of Cyrene
435 BCE - 356 BCE
Aristippus of Cyrene advocated for living a good life by prioritizing pleasure as the highest value and avoiding pain, which he considered the lowest. To be happy, one should actively seek pleasurable experiences and adapt circumstances to oneself, ensuring that pleasure is pursued with self-control and mastery over desires. His motto, "I possess; I am not possessed," emphasizes the importance of controlling one's indulgences to prevent addiction or enslavement to pleasure. Aristippus advised breaking social conventions if necessary to achieve pleasure, but always with the awareness and control to avoid being dominated by desires. Avoiding pain and maintaining adaptability in both adversity and prosperity are key to his philosophy, ensuring that pleasure leads to a fulfilling life without compromising personal freedom.
Challenge
Plato
Plato challenged Aristippus' hedonistic views by arguing that the good life is achieved through the pursuit of higher ideals and virtues, rather than mere pleasure. He believed that true happiness comes from the soul's alignment with the Forms, particularly the Form of the Good, which transcends physical pleasures.
Stoics (e.g., Seneca, Epictetus)
Stoic philosophers like Seneca and Epictetus challenged Aristippus' focus on pleasure by advocating for a life of virtue and rational control over one's desires. They believed that happiness is found in accepting the natural order and maintaining inner peace, regardless of external pleasures or pains.
Build Upon
Epicurus
Epicurus was influenced by Aristippus' ideas but sought to refine them by emphasizing the importance of mental pleasures over physical ones and advocating for a life of moderation to avoid pain. He believed that the absence of pain (ataraxia) was the key to happiness, thus building upon Aristippus' notion that pleasure is the highest value.
Platonism
Plato
427 BCE - 347 BCE
To live a good life according to Plato, one must cultivate virtue and seek knowledge, aligning actions with the true nature of reality. Begin by "knowing yourself," as self-awareness is crucial for understanding your inner nature and overcoming negative emotions like anger and greed. Plato emphasizes the importance of living an examined life, where reason guides passion and appetite, creating harmony within the soul. Avoid the pursuit of mere pleasure, wealth, or power, as these can distract from the pursuit of truth, beauty, and goodness. Instead, focus on developing wisdom, self-discipline, justice, and courage, which are the four cardinal virtues that lead to eudaimonia, or flourishing. Engage in self-reflection regularly to ensure your actions align with your true self and aspirations, contributing to a just and harmonious society.
Challenge
Aristotle
Aristotle challenged Plato's idea of the good life by emphasizing the importance of external goods and the role of practical wisdom. While Plato focused on inner harmony and the pursuit of knowledge, Aristotle argued that a good life requires a balance of virtues and external factors such as health, wealth, and friendships. Aristotle believed that happiness (eudaimonia) is achieved through virtuous activity and the fulfillment of one's potential, which includes both internal and external goods.
Epicurus
Epicurus challenged Plato's view by placing pleasure at the center of a good life. While Plato saw the pursuit of higher knowledge and virtue as essential, Epicurus argued that the absence of pain and the presence of pleasure are the keys to happiness. He believed that simple pleasures, friendship, and a tranquil life lead to happiness, contrasting with Plato's focus on the metaphysical and intellectual aspects of the good life.
Build Upon
Immanuel Kant
Kant built upon Plato's idea that virtue is central to the good life, but he introduced the concept of duty and moral law. Kant argued that true happiness is found in acting according to moral duty, which aligns with Plato's emphasis on virtue. However, Kant added that moral actions should be performed out of respect for the moral law, not for the pursuit of happiness, thus integrating Plato's focus on virtue with a deontological framework.
Friedrich Nietzsche
Nietzsche built upon Plato's idea of 'knowing yourself' by emphasizing the importance of self-overcoming and the creation of one's own values. While Plato advocated for self-knowledge as a path to virtue, Nietzsche saw it as a means to transcend traditional values and create a unique, authentic life. Nietzsche's concept of the 'will to power' involves understanding and overcoming one's limitations, which aligns with Plato's idea of self-conquest but extends it to the creation of new values.
Cynicism
Diogenes
412 BCE - 323 BCE
Diogenes advocated for living a good life through radical simplicity and virtue. To achieve happiness, one should embrace self-sufficiency (autarkeia) and shamelessness (anaideia), focusing on fulfilling natural needs without shame. Diogenes emphasized freeing oneself from societal conventions, status, and material possessions, which he saw as distractions from true virtue. He lived ascetically, often in public spaces, to demonstrate that what is natural cannot be shameful. To live well, one should cultivate inner virtues and reject the pursuit of wealth, fame, and power, which hold no value in nature. Diogenes' philosophy teaches that happiness comes from living in accordance with nature and being true to oneself, avoiding the artificial values imposed by society.
Challenge
Epicurus
Epicurus challenged Diogenes' idea that virtue alone leads to happiness by arguing that pleasure is the ultimate goal of life. While Diogenes emphasized living simply and virtuously, Epicurus believed that happiness is achieved through the pursuit of moderate pleasures and the avoidance of pain, thus presenting a more hedonistic approach to the good life.
Build Upon
Antisthenes
Antisthenes, a student of Socrates, laid the groundwork for Cynicism by advocating for a life of virtue and self-sufficiency, which Diogenes took to its extreme. Antisthenes believed that virtue was the only good and that it was sufficient for happiness, a view that Diogenes expanded upon by rejecting societal norms and material possessions to live a life in accordance with nature.
Aristotelianism
Aristotle
384 BCE - 322 BCE
Aristotle's concept of the good life, or eudaimonia, is centered on living virtuously and achieving human flourishing. To live a good life, one should cultivate virtues such as courage, temperance, and wisdom, which are character traits developed through habitual practice. Aristotle emphasizes the importance of the Golden Mean, which involves finding a balance between extremes in behavior and emotions. Concretely, this means acting with moderation, being rational, and engaging in intellectual contemplation. Aristotle advises avoiding excesses like indulgence in pleasure, wealth, or honor, as these are not ends in themselves but means to support a virtuous life. Happiness, according to Aristotle, is an activity of the soul in accordance with virtue, and it is self-sufficient, pursued for its own sake rather than for external rewards. By living in accordance with reason and virtue, one can achieve a fulfilled and meaningful life.
Challenge
Epicurus
Epicurus challenged Aristotle's idea by proposing that the good life is one of mental tranquility and freedom from disturbance, emphasizing simple pleasures. He believed that happiness is achieved through the absence of pain and fear, rather than through virtuous actions alone. This reflects a more hedonistic approach compared to Aristotle's virtue ethics.
Zeno of Citium
Zeno, the founder of Stoicism, challenged Aristotle by emphasizing the importance of living in accordance with nature and reason, rather than focusing solely on virtue. Stoicism teaches that the good life is achieved through inner peace and resilience, regardless of external circumstances, which contrasts with Aristotle's emphasis on moral virtue and external goods.
Build Upon
Thomas Aquinas
Thomas Aquinas built upon Aristotle's ideas by integrating them into Christian theology. He believed that the good life involves living virtuously in accordance with reason and divine law. Aquinas expanded Aristotle's virtue ethics by incorporating the concept of divine grace, suggesting that true happiness is found in union with God, thus blending Aristotelian ethics with Christian doctrine.
Alasdair MacIntyre
Alasdair MacIntyre built upon Aristotle's ideas in his work 'After Virtue,' where he argues for a return to Aristotelian virtue ethics in modern moral philosophy. MacIntyre emphasizes the importance of community and tradition in achieving the good life, suggesting that virtues are cultivated within social practices. He sees Aristotle's framework as a solution to the moral fragmentation of contemporary society.
Skepticism
Pyrrho of Elis
360 BCE - 270 BCE
To live a good life according to Pyrrho of Elis, one should practice epoché, which means suspending judgment about beliefs and perceptions. This leads to ataraxia, a state of tranquility and freedom from disturbance. Concretely, this involves resisting the urge to make definitive judgments about the nature of reality, as our senses and perceptions are unreliable. Instead, live according to appearances without asserting truth or falsehood. Avoid dogmatism, which is the overconfident belief in non-evident matters, as it prevents achieving eudaimonia, or flourishing. By embracing uncertainty and refraining from making absolute claims, one can attain inner peace and happiness.
Challenge
Epicurus
Epicurus challenged Pyrrho's skepticism by proposing that happiness is achieved through the pursuit of pleasure and the avoidance of pain. Unlike Pyrrho, who advocated for suspension of judgment, Epicurus believed that sensory experiences could be trusted to guide one towards a pleasurable life. Epicurus' philosophy was more dogmatic, emphasizing the importance of rational thought and empirical evidence in achieving eudaimonia, or human flourishing.
Aristotle
Aristotle challenged Pyrrho's idea of ataraxia, or tranquility, as the ultimate goal of life. Instead, Aristotle proposed that the good life is achieved through the cultivation of virtues and rational activity, leading to eudaimonia. Aristotle's philosophy was based on the belief that humans have a natural purpose and that fulfilling this purpose through virtuous actions leads to true happiness, contrasting with Pyrrho's suspension of judgment and skepticism about the nature of reality.
Build Upon
Sextus Empiricus
Sextus Empiricus built upon Pyrrho's skepticism by further developing the concept of epoché, or suspension of judgment, as a means to achieve ataraxia. He expanded Pyrrho's ideas into a comprehensive system of skepticism, arguing that by suspending judgment on all matters, one can attain mental tranquility. Sextus Empiricus' works played a significant role in the revival of Pyrrhonism during the Renaissance, influencing modern philosophical thought on skepticism.
Aenesidemus
Aenesidemus built upon Pyrrho's skepticism by introducing the 'modes' or 'tropes' of skepticism, which are arguments designed to show the uncertainty of knowledge and perception. He emphasized the relativity of sensory experiences and the impossibility of attaining certain knowledge, reinforcing Pyrrho's idea that reality is inapprehensible. Aenesidemus' work helped establish Pyrrhonism as a distinct philosophical school, furthering the exploration of skepticism in ancient philosophy.
Epicureanism
Epicurus
341 BCE - 270 BCE
Epicurus advocates for a life centered around simple pleasures and the avoidance of unnecessary desires to achieve happiness. His philosophy emphasizes ataraxia (inner tranquility) and aponia (absence of physical pain) as the highest forms of pleasure. To live a good life, focus on fulfilling natural and necessary desires, such as friendship and intellectual pursuits, rather than indulging in luxury or excess. Cultivate a mindset free from fear of death and divine retribution, as these anxieties are unnecessary. Avoid desires that lead to distress and pain, as they disrupt mental peace. By prioritizing stable pleasures and philosophical reflection, one can attain a state of imperturbability and live harmoniously within a community.
Challenge
Aristotle
Aristotle challenges Epicurus by asserting that happiness is achieved through a life of virtuous activity, not merely the absence of pain. Aristotle's concept of eudaimonia involves flourishing through the exercise of virtue, which contrasts with Epicurus' focus on minimizing pain and anxiety. Aristotle's view reflects the broader Greek tradition that associates happiness with moral virtue.
Stoics
The Stoics challenge Epicurus by equating happiness with virtue, arguing that true happiness comes from living in accordance with nature and reason, which inherently involves virtuous living. Unlike Epicurus, who sees happiness as freedom from pain, the Stoics believe that virtue is both necessary and sufficient for happiness, emphasizing moral integrity over the pursuit of pleasure.
Build Upon
Lucretius
Lucretius builds upon Epicurus by presenting his ideas in the epic poem 'De rerum natura,' which articulates Epicurean philosophy as a means to achieve tranquility and happiness. Lucretius emphasizes the therapeutic aspect of Epicurus' teachings, advocating for a life free from fear and anxiety through understanding the natural world and limiting desires. His work helped preserve and propagate Epicurean thought during the Roman era.
Thomas Jefferson
Thomas Jefferson admired Epicurus and incorporated his ideas into his own philosophy, particularly the emphasis on simple pleasures and the importance of friendship. Jefferson saw Epicureanism as a guide to personal happiness and well-being, valuing the pursuit of modest pleasures and the cultivation of social bonds as essential to a fulfilling life. This reflects Epicurus' influence on Enlightenment thinking and the shaping of modern concepts of happiness.
Stoicism
Zeno, Seneca, Epictetus, Marcus Aurelius
300 BCE - 200 CE
Stoicism, founded by Zeno of Citium, teaches that the path to a good life lies in living in harmony with nature and reason, prioritizing virtue, and cultivating freedom from destructive passions. Zeno established the central doctrine that virtue alone is sufficient for happiness, introducing the concept of apatheia (freedom from passions) and emphasizing that external wealth and honors are indifferent compared to inner moral excellence. In the Roman period, Seneca the Younger emphasized the wise use of time and the importance of living immediately rather than deferring happiness to the future. He urged self-improvement, equanimity in the face of death, and appreciation of the present moment, warning against ambition and misplaced desires. Epictetus, born a slave, highlighted the distinction between what is within our control—our thoughts, choices, and character—and what is not, teaching that true freedom and happiness come from mastering inner responses rather than external circumstances. Marcus Aurelius, the Roman emperor, integrated Stoic principles into his personal reflections and governance, stressing kindness, justice, and self-discipline, acceptance of fate, and serenity through control of one’s mind. Together, these thinkers shaped Stoicism into a practical philosophy of resilience, inner freedom, and virtuous living.
Challenge
Aristotle
Aristotle’s concept of eudaimonia (flourishing) both overlaps with and challenges Stoicism. Like the Stoics, he made virtue central to the good life, but he argued that virtue is not self-sufficient without external goods such as health, wealth, and friendship. This diverges from the Stoic view that virtue alone guarantees happiness, regardless of circumstances.
Epicurus
Epicurus presented a rival view that the good life is achieved through pleasure, understood as tranquility (ataraxia) and freedom from pain (aponia). While Stoics considered pleasure an 'indifferent' and saw virtue as the sole good, Epicurus treated virtue as valuable mainly because it leads to peace of mind. This subtle but key difference marked a deep opposition: for Stoics virtue is the end, for Epicureans it is the means.
Friedrich Nietzsche
Nietzsche criticized Stoicism for what he saw as its denial of life’s creative struggles. In 'Beyond Good and Evil,' he mocked Stoics for trying to 'live according to nature' while in fact imposing their rational laws upon it. He rejected Stoic resignation and calm detachment, arguing instead for embracing struggle and self-overcoming as expressions of the 'will to power.' Whereas Stoics sought equanimity through self-restraint, Nietzsche valued the creation of new values and the affirmation of life’s hardships.
Neoplatonism
Plotinus
205 CE - 270 CE
Plotinus advocates for achieving eudaimonia, or well-being, through theoria, the contemplation of true being in the intelligible realm of Nous. To live a good life, one should focus on the noetic ascent of the soul, striving to become godlike by aligning with the higher, unchangeable part of the soul. This involves detaching from material desires and the distractions of the sensible world, which Plotinus views as a source of evil. Instead, cultivate interiority and self-sufficiency by identifying with intelligible truths, fostering a serene and blissful state immune to misfortune. Avoid attachment to bodily desires and external circumstances, as true happiness is found in the cognitive identification with the divine and eternal reality. Embrace philia, or friendship, to share eudaimonia with others, reflecting the unity of the higher divine realm.
Challenge
Aristotle
Aristotle's concept of eudaimonia involves virtuous activity and ethical practice as central to achieving happiness. He challenges Plotinus by emphasizing the importance of practical virtues and the role of ethical actions in living a flourishing life, contrasting with Plotinus' focus on intellectual contemplation.
Iamblichus
Iamblichus, a later Neoplatonist, diverged from Plotinus by emphasizing theurgy and the role of divine intervention in the soul's ascent. He challenged Plotinus' idea that contemplation alone leads to eudaimonia, arguing that rituals and divine assistance are necessary for the soul's union with the divine.
Build Upon
Porphyry
Porphyry, a student of Plotinus, documented Plotinus' life and philosophy, emphasizing the importance of the contemplative life and the ascent of the soul. He supported Plotinus' idea that true happiness is achieved through intellectual and spiritual pursuits, rather than material or bodily pleasures.
Christian Platonism
Augustine of Hippo
354 CE - 430 CE
To live a good life according to Augustine of Hippo, one must cultivate a "good will" by converting to God, the source of divine light, which illuminates the truth of right and wrong. This conversion involves embracing Christian teachings and living a life of virtue, guided by faith, hope, and charity. Augustine emphasizes the importance of aligning one's will with God's grace, as human nature is flawed and requires divine intervention for true happiness. Practically, this means rejecting hedonistic pursuits and sinful behaviors such as pride, lust, and blasphemy, which Augustine himself struggled with before his conversion. Instead, one should seek wisdom, practice self-control, and engage in prayer and the sacraments to attain eternal stability and happiness. Augustine's famous phrase, "Our hearts are restless until they rest in you," encapsulates the idea that true contentment is found in God alone.
Challenge
Pelagius
Pelagius challenged Augustine's views on grace by arguing that human beings have the innate ability to choose good and live a virtuous life without the need for divine grace. He believed that human will and effort are sufficient for achieving righteousness and happiness. This led to the Pelagian controversy, where Augustine defended the necessity of grace, asserting that human nature is flawed and requires divine assistance for true virtue and happiness.
Immanuel Kant
Immanuel Kant challenged Augustine's integration of divine illumination with ethics by proposing a moral philosophy based on reason and autonomy. Kant argued that moral law is derived from rationality and that happiness is achieved through adherence to duty, independent of divine influence. While Augustine emphasized the role of divine grace in leading a virtuous life, Kant believed that moral actions should be guided by reason alone, thus separating ethics from religious doctrine.
Build Upon
Thomas Aquinas
Thomas Aquinas built upon Augustine's ideas by integrating them into his own theological framework. Aquinas agreed with Augustine that divine illumination is essential for understanding truth, but he further developed this by arguing that human reason, aided by divine grace, can lead to knowledge and happiness. Aquinas emphasized the harmony between faith and reason, suggesting that while divine illumination is crucial, human intellect also plays a significant role in understanding and achieving happiness.
Martin Luther
Martin Luther was deeply influenced by Augustine's doctrine of grace, which he saw as central to the Christian life. Luther expanded on Augustine's ideas by emphasizing the concept of 'justification by faith alone,' arguing that it is through God's grace, not human works, that one achieves righteousness and happiness. Luther's Reformation theology was rooted in the belief that divine grace is the sole means by which humans can attain a good life and eternal happiness, reflecting Augustine's emphasis on the necessity of divine intervention.
Peripatetic / Islamic philosophy
Avicenna
980 CE - 1037 CE
Avicenna, a prominent philosopher, emphasized living a good life through the pursuit of knowledge and the cultivation of the rational soul. To achieve happiness, one should engage in acts of worship and intellectual exercises that predispose the soul to intellection, aligning with the concept of eudaimonia or flourishing. Avicenna advocated for a life dominated by the love of God, which facilitates the attainment of the highest knowledge. He warned against succumbing to mere sensory pleasures and distractions, as these can lead to a life of wastefulness and hinder the soul's journey towards enlightenment. By focusing on intellectual and spiritual growth, and avoiding superficial pursuits, one can live a fulfilling and meaningful life.
Challenge
Averroes (Ibn Rushd)
Averroes, known for his commentaries on Aristotle, challenged Avicenna's approach to integrating philosophy with Islamic theology. He argued for a more distinct separation between philosophy and religion, emphasizing the autonomy of philosophical inquiry. Averroes believed that philosophical truths should be pursued independently of religious doctrines, which contrasted with Avicenna's attempt to harmonize the two. This challenge led to significant debates in the Islamic world regarding the role of philosophy in relation to religious belief.
Al-Ghazali
Al-Ghazali, a prominent Islamic theologian, challenged Avicenna's philosophical system, particularly his metaphysical ideas. Al-Ghazali argued that Avicenna's reliance on philosophical reasoning could lead to theological errors and undermine religious faith. He criticized Avicenna's views on the eternity of the world and the nature of God's knowledge, advocating for a more faith-based approach to understanding divine truths. This critique was part of a broader movement to defend Islamic theology against perceived threats from philosophical speculation.
Build Upon
Thomas Aquinas
Thomas Aquinas was significantly influenced by Avicenna's work, particularly in the realm of metaphysics and the integration of Aristotelian philosophy with religious thought. Aquinas adopted Avicenna's ideas on the existence of God and the nature of the soul, using them to further develop his own theological and philosophical system. Aquinas's synthesis of faith and reason was partly inspired by Avicenna's approach, which sought to harmonize philosophical inquiry with theological principles.
Mulla Sadra
Mulla Sadra, a prominent philosopher of the school of Isfahan, creatively modified Avicenna's metaphysical ideas. He built upon Avicenna's concepts by introducing his own philosophical system known as Transcendent Theosophy, which combined metaphysics, theology, and mysticism. Sadra's work represents a significant evolution of Avicenna's ideas, demonstrating how they could be expanded and adapted to address new philosophical questions and contexts.
Scholasticism
Anselm of Canterbury
1033 CE - 1109 CE
To live a good life according to Anselm of Canterbury, one must prioritize seeking God and aligning oneself with divine wisdom and goodness. Anselm emphasizes the importance of contemplative prayer, urging individuals to enter the "cell of your mind," shutting out distractions to focus solely on God. This introspection helps uncover one's true essence and purpose, fostering wisdom and self-awareness. Anselm advises avoiding the pursuit of short-term pleasures and worldly distractions, as they detract from the ultimate goal of divine union and understanding. By seeking God's face and trusting in His goodness, individuals can find true happiness and fulfillment. Anselm's approach is rooted in the belief that understanding and loving God leads to a transformative process, enabling one to embrace their authentic self and live a life of righteousness.
Challenge
Peter Abelard
Peter Abelard challenged Anselm's approach by emphasizing the role of dialectical reasoning in theology. Abelard argued that logical analysis and questioning are essential for understanding and interpreting religious doctrines. He believed that faith should be subject to rational scrutiny, which sometimes led to conflicts with established theological views, including those of Anselm.
Build Upon
Thomas Aquinas
Thomas Aquinas, a key figure in Scholasticism, built upon Anselm's ideas by integrating Aristotelian philosophy with Christian theology. Aquinas expanded on Anselm's rational approach to faith, arguing that reason and faith are complementary in understanding divine truths. He believed that while faith is necessary for salvation, reason can lead to a deeper understanding of God and the moral life.
Jewish Aristotelianism
Moses Maimonides
1138 CE - 1204 CE
Moses Maimonides, a medieval Jewish philosopher, emphasized living a good life through the pursuit of human perfection, achievable by fulfilling the commandments and adhering to tradition. To be happy and live well, one should engage in "imitatio Dei," emulating God's attributes, which involves cultivating virtues such as wisdom, justice, and compassion. Maimonides advocated for the "golden mean," a balanced approach to life, avoiding extremes in behavior and emotion. He stressed the importance of intellectual and spiritual development, suggesting that knowledge of God should overflow into ethical actions and community service. Avoiding idolatry, injustice, and harmful actions is crucial, as these detract from one's spiritual and moral growth. By aligning one's life with divine wisdom and maintaining a healthy lifestyle, both physically and spiritually, individuals can achieve fulfillment and contribute positively to society.
Challenge
Al-Ghazali
Al-Ghazali, a prominent Islamic philosopher, challenges Maimonides' view by emphasizing the mystical and spiritual aspects of religious tradition in achieving human perfection. While Maimonides focuses on rational understanding and adherence to commandments, Al-Ghazali argues for a more spiritual approach, where inner purification and mystical experience are crucial for true happiness and perfection. This reflects a broader Islamic philosophical tradition that values spiritual insight over purely rational or legalistic adherence.
Spinoza
Spinoza, a later Jewish philosopher, challenges Maimonides by advocating for a purely rationalist approach to happiness and human perfection. He argues that true happiness comes from understanding the universe through reason, rather than through religious tradition or commandments. Spinoza's philosophy suggests that Maimonides' integration of Jewish law with Aristotelian ethics is insufficient for achieving true happiness, as it relies too heavily on tradition rather than rational insight.

Thomas Aquinas
Thomas Aquinas, influenced by Maimonides, also sees faith as integral to achieving the good life. While Maimonides emphasizes the perfection of the human being through adherence to commandments and tradition, Aquinas expands this by incorporating Christian theology, suggesting that faith is a virtue that leads to moral and spiritual perfection. Aquinas' model of spiritually formative moral epistemology offers advantages over Maimonides' approach, which some critics describe as lacking in spiritual engagement.
Aristotle
Maimonides was heavily influenced by Aristotle, particularly in his understanding of human perfection and happiness. Aristotle's notion of eudaimonia, or flourishing, through the cultivation of virtues is mirrored in Maimonides' emphasis on the fulfillment of commandments and fidelity to tradition as means to perfect oneself. Maimonides adapts this Aristotelian framework to fit within a Jewish context, arguing that the Torah is a perfect guide to achieving this perfection.
Thomism (Aristotelian Scholasticism)
Thomas Aquinas
1225 CE - 1274 CE
To live a good life according to Thomas Aquinas, one should cultivate virtues and seek communion with God. Aquinas emphasizes the importance of the cardinal virtues: prudence, temperance, fortitude, and justice, which guide moral behavior and help achieve eudaimonia, or human flourishing. Practically, this involves making wise decisions, moderating desires, showing courage in adversity, and treating others fairly. Aquinas also highlights the significance of intellectual contemplation and spiritual practices like prayer and meditation to align oneself with divine will. Avoiding excessive attachment to worldly pleasures and material wealth is crucial, as these can distract from the ultimate goal of union with God. Aquinas believes that while perfect happiness is reserved for the afterlife, a meaningful and virtuous life can lead to a form of happiness in this world. Thus, living a good life involves balancing moral virtues with spiritual pursuits, aiming for both personal and communal well-being.
Challenge
St. Augustine
St. Augustine challenges Aquinas's view by asserting that perfect happiness is not attainable in this lifetime, but only in the afterlife. Augustine's perspective is rooted in the belief that earthly life is plagued with unsatisfied desires and that true happiness is found in the anticipation of heavenly life. Aquinas, while agreeing that ultimate happiness is in the afterlife, believes that a certain degree of happiness can be achieved in this life through virtuous living.
Build Upon
Aristotle
Aristotle's philosophy of Eudaimonia, or human flourishing, is foundational to Aquinas's ideas about the good life. Aquinas builds upon Aristotle's virtue ethics, emphasizing the development of virtues as essential to achieving a good life. Aquinas integrates this with Christian theology, suggesting that ultimate happiness is found in union with God, which complements Aristotle's idea of living a life in accordance with virtue.
Scotism / Scholasticism
Duns Scotus
1266 CE - 1308 CE
Duns Scotus emphasizes living a good life through the exercise of free will aligned with divine goodness. To be happy, one should cultivate virtues and make choices that reflect the will of God, as Scotus advocates for a moderate voluntarism where human freedom is harmonized with divine law. Practically, this means engaging in acts of charity, seeking truth, and nurturing a relationship with God. Avoid actions that contradict divine goodness, such as sin, which disrupts the connection between being and goodness. Scotus’s concept of "haecceity" underscores the importance of individual uniqueness in moral decisions, suggesting that personal integrity and authenticity are crucial for a fulfilling life. By aligning one's will with divine goodness, individuals can achieve true happiness and moral excellence.
Challenge
Thomas Aquinas
Thomas Aquinas, a prominent philosopher of the High Middle Ages, held a view that emphasized the role of intellect in guiding the will towards the good, which contrasts with Scotus's moderate voluntarism that gives more autonomy to the will. Aquinas believed that true happiness is achieved through the intellect's understanding of God and the alignment of the will with this understanding. Scotus's emphasis on the will's freedom challenged Aquinas's more deterministic view, leading to significant debates in scholastic philosophy about the nature of free will and its role in achieving happiness.
William of Ockham
William of Ockham, a fellow Franciscan and philosopher, is known for his nominalist position, which challenges Scotus's realism about universals. Ockham argued that universals are merely names or labels we use to describe collections of individual things, rather than real entities existing independently. This view contrasts with Scotus's belief in the existence of universal realities. Ockham's nominalism implies a more individualistic approach to ethics and living a good life, focusing on particular actions and choices rather than abstract universal principles. This philosophical divergence highlights the ongoing debate about the role of universals in ethical reasoning and the pursuit of happiness.
Build Upon
Bonaventure
Bonaventure, a predecessor and influential figure in the Franciscan tradition, emphasized the importance of divine illumination in understanding truth and achieving happiness. Scotus's distinction between intuitive and abstractive cognition builds upon Bonaventure's ideas by providing a more nuanced framework for understanding how humans perceive and know divine truths. While Bonaventure focused on the mystical and spiritual aspects of cognition, Scotus offered a more structured philosophical approach, which influenced later discussions on the nature of knowledge and its role in living a good life. This connection illustrates the continuity and development of thought within the Franciscan intellectual tradition.
Gerard Manley Hopkins
Gerard Manley Hopkins, a Jesuit poet, was deeply influenced by Scotus's metaphysical views, particularly the connection between being and goodness. Hopkins's poetry often reflects Scotus's idea that beauty and goodness are intertwined, suggesting that recognizing and appreciating beauty in the world is integral to living a good life. Scotus's philosophical foundation provided Hopkins with a framework to explore the spiritual and aesthetic dimensions of existence, emphasizing the importance of beauty in achieving happiness and fulfillment. This relationship highlights the enduring impact of Scotus's ideas on later thinkers and artists who sought to integrate philosophical concepts into their creative expressions.
Scientific method
Galileo Galilei
1564 CE - 1642 CE
To live a good life according to Galileo Galilei, embrace curiosity and the pursuit of truth. Cultivate a mindset that values empirical evidence and reason over dogma, as Galileo did in his scientific endeavors. Engage actively with the world, question established beliefs, and seek knowledge through observation and experimentation. Avoid blind adherence to authority or tradition, as Galileo's defiance of prevailing geocentric views exemplifies. Instead, rely on your intellect and reasoning to guide your actions. Practically, this means nurturing a habit of critical thinking, being open to new ideas, and continuously learning. By doing so, you align with Galileo's philosophy of living a life enriched by discovery and understanding, leading to personal fulfillment and happiness.
Challenge
Immanuel Kant
Kant challenged the notion that empirical evidence alone could lead to ultimate truth.

Bacon admired Galileo's empirical approach and further developed the scientific method, advocating for systematic experimentation and observation. He believed that knowledge should be derived from empirical evidence, aligning with Galileo's philosophy of defying dogma and pursuing truth through observation and experimentation.
Rationalism / Monism
Baruch Spinoza
1632 CE - 1677 CE
To live a good life according to Baruch Spinoza, one must embrace reality and strive to become a "free person" guided by reason rather than passions. This involves understanding the causes of emotions and mastering them through rational thought, which leads to virtue and emotional regulation. Spinoza emphasizes the importance of living in accordance with nature and reason, which allows individuals to act in their true self-interest and achieve happiness. Concretely, one should cultivate friendships, love, and compassion, strive towards personal goals, and find meaning in life. Avoid living in bondage to emotions, pursuing transitory goods, and being driven by superstitions or irrational fears, such as the fear of death. By focusing on improving oneself and others, treating people with benevolence, and living a life of moderation, one can attain joy and fulfillment.
Challenge
Friedrich Nietzsche
Nietzsche challenges Spinoza's emphasis on reason and virtue as the path to happiness. Nietzsche believed that life is driven by the 'will to power' and that embracing one's instincts and passions is essential for a fulfilling life. He criticized the idea of suppressing emotions and argued that true happiness comes from living authentically and embracing one's individuality, rather than conforming to rational ideals.
Immanuel Kant
Kant challenges Spinoza's deterministic view by emphasizing the importance of free will and moral autonomy. Kant argued that reason is not just a tool for understanding the world but is essential for moral decision-making. He believed that humans have the capacity for free will and that moral actions are determined by adherence to duty and the categorical imperative, rather than being bound by deterministic forces.

She believed that Spinoza's focus on reason and understanding could guide individuals in living a virtuous life. Eliot's novels often explore themes of moral development and the importance of empathy and compassion, reflecting Spinoza's belief in the interconnectedness of individuals and the pursuit of collective well-being.
Rationalism
Gottfried Leibniz
1646 CE - 1716 CE
To live a good life according to Gottfried Leibniz, embrace the idea that we exist in "the best of all possible worlds." This perspective encourages acceptance and gratitude for the present circumstances, recognizing that every event has a reason and contributes to the overall harmony of the universe. To be happy, cultivate optimism and seek knowledge, as Leibniz believed that understanding the interconnectedness of events can lead to greater wisdom and contentment. Avoid dwelling on perceived imperfections or evils, as they may be necessary components of a greater good. Instead, focus on improving oneself and the world through reason and thoughtful action, aligning with Leibniz's belief in the power of rationality and the pursuit of knowledge.

Voltaire famously challenged Leibniz's optimistic view through his satirical novella 'Candide'. In this work, Voltaire ridicules the idea that we live in the best of all possible worlds by highlighting the absurdity and suffering present in life. Voltaire's critique was rooted in the Enlightenment's emphasis on reason and empirical evidence, contrasting Leibniz's metaphysical optimism.
Build Upon
Immanuel Kant
Kant built upon Leibniz's rationalist ideas by further developing the concept of metaphysical idealism. While Leibniz proposed that reality is composed of non-interacting monads, Kant introduced the idea that our understanding of reality is shaped by the structures of our mind. Kant's 'Critique of Pure Reason' reflects the influence of Leibniz's rationalism, as Kant sought to reconcile rationalist and empiricist traditions in philosophy.
Deism / Liberal critique
Voltaire
1694 CE - 1778 CE
To live a good life according to Voltaire, embrace "cultiver notre jardin"—focus on personal growth and practical endeavors. Cultivate your mind through freedom of thought and reject superstition, as philosophy quenches the flames of ignorance. Practice religious tolerance and defend the rights of others, as intolerance breeds conflict. Avoid blind optimism; instead, acknowledge life's challenges and work towards progress. Engage in reasoned discourse, as "opinion rules the world," and strive for justice through action, not just reflection. Cherish friendships, love your enemies, and detest superstition, as these are the keys to a fulfilling life.
Challenge
Jean-Jacques Rousseau
Rousseau challenged Voltaire's ideas by advocating for a more direct form of democracy, where the general will of the people is paramount. Rousseau believed that true happiness and freedom could only be achieved through a government that directly represents the will of its citizens, contrasting Voltaire's support for a constitutional monarchy. Rousseau's ideas were rooted in his belief that society corrupts natural goodness, and thus, a government should be more closely aligned with the people's direct interests.

Materialism / Encyclopedism
Denis Diderot
1713 CE - 1784 CE
Denis Diderot advocated for living a good life through intellectual freedom and skepticism. He believed that happiness comes from thinking independently, free from the constraints of religious dogma and state laws. To be happy, one should embrace reason, experiment, and pursue knowledge through scientific inquiry and personal experience. Diderot emphasized the importance of individuality, suggesting that education should be tailored to each person's unique abilities and interests. He warned against blind adherence to tradition and authority, advocating instead for a life of critical thinking and open-mindedness. By valuing reason and empirical evidence, individuals can forge their own paths to happiness and fulfillment, avoiding the pitfalls of dogmatism and prejudice.
Challenge
Jean-Jacques Rousseau
Rousseau challenged Diderot's ideas by emphasizing the importance of collective social structures and the 'general will' over individual desires. Rousseau believed that true happiness and a good life could only be achieved through a social contract that aligns individual interests with the common good, contrasting Diderot's focus on personal freedom and self-determined paths to happiness.

Both philosophers were central figures in the Enlightenment movement, rallying others around these ideals.
Positivism
Auguste Comte
1798 CE - 1857 CE
Auguste Comte advocated living a good life through altruism, sociocracy, and the Religion of Humanity. To be happy, one should practice altruism, which means prioritizing the welfare of others over self-interest, encapsulated in his command "Live for Others." This fosters social bonds and a sense of purpose. Embrace sociocracy by participating in cooperative decision-making, ensuring that societal progress is based on collective well-being. Comte's Religion of Humanity suggests celebrating human achievements and fostering unity without supernatural beliefs. Avoid egoism and individualism, as they disrupt social harmony and personal fulfillment. Comte's motto, "Love as a principle, order as the basis, progress as the goal," serves as a guide: cultivate compassion, maintain clarity and structure in life, and commit to continuous growth. By integrating these principles, one can achieve a meaningful and happy life, contributing positively to society.

Mill's work on utilitarianism and liberty reflects a synthesis of individual freedom with the moral obligation to contribute to the greater good, aligning with Comte's vision of a society where individuals work for the common good.
Utilitarianism / Liberalism
Stuart Mill
1806 CE - 1873 CE
Stuart Mill advocates for living a good life through the "greatest happiness principle," which emphasizes maximizing overall happiness rather than focusing solely on personal wellbeing. To achieve this, one should engage in actions that promote higher pleasures—intellectual and moral pursuits—over lower, bodily pleasures. Mill suggests that happiness is often found indirectly by aiming at goals beyond personal satisfaction, such as contributing to the happiness of others or pursuing meaningful projects. Avoiding selfish indulgence and narrow self-interest is crucial, as these can detract from the broader happiness of society. Mill also stresses the importance of individual freedom and choice, encouraging people to pursue their own good in their own way, provided they do not infringe on others' freedom. By balancing personal liberty with a commitment to the greater good, one can lead a fulfilling and ethical life.
Challenge
Immanuel Kant
Immanuel Kant challenges Mill's utilitarianism by arguing that moral actions are not based on the consequences they produce, but rather on whether they adhere to a categorical imperative. Kant believes that actions should be guided by duty and universal moral laws, rather than the pursuit of happiness for the greatest number. This reflects a fundamental difference in ethical reasoning between deontological and consequentialist approaches.
Friedrich Nietzsche
Friedrich Nietzsche challenges Mill's utilitarianism by rejecting the idea that happiness is the ultimate goal of life. Nietzsche argues that life should be about the pursuit of individual greatness and the expression of one's will to power. He criticizes utilitarianism for promoting mediocrity and conformity, suggesting instead that individuals should strive for self-overcoming and the creation of personal values.

This refinement aims to address criticisms of Bentham's more simplistic hedonistic calculus.
Peter Singer
Peter Singer builds upon Mill's utilitarianism by extending the principle of maximizing happiness to global ethics, particularly in the context of animal rights and effective altruism. Singer argues for a broader consideration of sentient beings' welfare, advocating for actions that reduce suffering and promote well-being across species. His work emphasizes the practical application of utilitarian principles in addressing global issues, such as poverty and animal exploitation.
Existentialism/ Christian philosophy
Søren Kierkegaard
1813 CE - 1855 CE
To live a good life according to Søren Kierkegaard, one must embrace the concept of "living forwards" while understanding life "backwards." This means actively engaging with life, making decisions, and taking responsibility for one's actions, rather than merely theorizing or seeking external validation. Kierkegaard emphasizes the importance of living authentically, avoiding distractions and busyness that lead to unhappiness. He suggests focusing on internal fulfillment rather than external achievements, and encourages embracing uncertainty and making peace with past experiences. To be happy, one should cultivate faith, ethical behavior, and personal responsibility, while avoiding the trap of living in the aesthetic stage, which is characterized by superficial pleasures and distractions. By living with purpose and commitment, and by understanding oneself deeply, one can achieve true contentment and happiness.

Existentialism / Genealogy / Nihilism
Friedrich Nietzsche
1844 CE - 1900 CE
To live a good life according to Friedrich Nietzsche, one must embrace the concept of the "will to power," which is about realizing one's potential and achieving self-mastery, not domination over others. Strive to become the Ăśbermensch, transcending mediocrity and pursuing excellence. Embrace suffering as a path to growth, and seek challenges to enrich your life. Practice "amor fati," loving your fate and accepting life's hardships as necessary. Avoid the "Last Man" mentality, which seeks comfort and avoids pain, leading to a dull existence. Live authentically, blending the Dionysian (passion) and Apollonian (reason) aspects of life, and reflect on the "eternal recurrence" to ensure your choices lead to a meaningful existence.
Challenge
Karl Marx
Marx's philosophy focuses on economic structures and class struggle as the driving forces of societal change, which contrasts with Nietzsche's idea of the will to power as an individualistic drive for self-realization and mastery.

Analytic philosophy / Logicism
Bertrand Russell
1872 CE - 1970 CE
Bertrand Russell suggests that to live a good life, one should be inspired by love and guided by knowledge. Practically, this means cultivating meaningful relationships and pursuing intellectual growth. To be happy, expand your interests beyond personal concerns, allowing your ego to merge with the universal life, akin to a river flowing into the sea. Avoid living in isolation or as a "parasite" on society; instead, engage with the community and contribute positively. Russell warns against the pursuit of happiness that ignores instinctive joy, advocating for moral rules that support rather than hinder happiness. He emphasizes the importance of living in a good society, as political and social environments can significantly impact one's ability to live well. Ultimately, balance love and knowledge, broaden your interests, and foster a harmonious relationship with society to achieve a fulfilling life.

Phenomenology / Existential ontology
Martin Heidegger
1889 CE - 1976 CE
To live a good life according to Martin Heidegger, one must strive for authenticity by taking responsibility for their own choices and embracing the inevitability of death, which he terms "Being-toward-death." This involves acknowledging one's mortality to free oneself from the anxiety of death and the triviality of life, thus enabling true self-discovery. Heidegger advises against living inauthentically, which means allowing one's life to be dictated by societal norms and the expectations of "the they" (das Man), leading to a life of common-sense ambiguity and unexamined decisions. Instead, one should live each moment as part of a coherent narrative, integrating past experiences into a meaningful future. By confronting existential anxiety and guilt, and by spending time in contemplation, perhaps even in graveyards, individuals can cultivate a deeper understanding of their existence and live a richer, more thoughtful life.
Challenge
Theodor Adorno
Theodor Adorno challenges Heidegger's concept of authenticity by critiquing its individualistic nature. Adorno argues that Heidegger's focus on personal authenticity neglects the social and historical conditions that shape individual existence. He believes that Heidegger's philosophy fails to address the systemic issues and power structures that influence human life, thus limiting the potential for genuine freedom and happiness. Adorno's critique is rooted in his broader critique of existentialism, which he sees as insufficiently critical of societal influences.
Emmanuel Levinas
Emmanuel Levinas challenges Heidegger's ideas by emphasizing the ethical dimension of human existence, particularly the encounter with the 'Other.' Levinas argues that Heidegger's focus on individual authenticity overlooks the ethical responsibility we have towards others. He believes that true authenticity arises not from introspection or confronting one's mortality, but from the ethical relationship with others, which calls us to respond to their needs and vulnerabilities. Levinas's critique is grounded in his philosophy of ethics as first philosophy, prioritizing the ethical over the ontological.
Build Upon
Jean-Paul Sartre
Jean-Paul Sartre, a leading existentialist philosopher, builds upon Heidegger's ideas by emphasizing the importance of confronting one's own mortality to achieve authenticity. Sartre agrees with Heidegger that acknowledging death is crucial for living authentically, but he further develops this by focusing on the concept of 'bad faith'—the denial of one's freedom and responsibility. Sartre argues that individuals often deceive themselves to escape the anxiety of freedom, and only by accepting the inevitability of death can one live a life true to oneself.
Hannah Arendt
Hannah Arendt, a student of Heidegger, builds upon his ideas by exploring the role of responsibility in the public sphere. While Heidegger focuses on individual authenticity, Arendt extends this to the realm of political action, emphasizing the importance of taking responsibility for one's actions in the context of a community. She argues that true freedom and a good life are achieved through active participation in public life, where individuals take responsibility for their choices and contribute to the common good.
Existentialism
Jean-Paul Sartre
1905 CE - 1980 CE
Jean-Paul Sartre advocates living a good life through authenticity, which involves embracing our radical freedom and taking full responsibility for our choices. To achieve happiness, one must reject "bad faith," a state where individuals deny their freedom by conforming to societal roles or external expectations. Instead, Sartre encourages us to create our own meaning and values, as "existence precedes essence," meaning we define our essence through actions. Concretely, this means making choices that align with our true self, pursuing passions, and accepting the consequences of our actions. Avoid living passively or blaming external factors for your circumstances, as this leads to inauthenticity and unhappiness. By acknowledging our freedom and responsibility, we can live a life that is genuinely fulfilling and meaningful.

Simone de Beauvoir
Simone de Beauvoir, Sartre's lifelong companion, expanded on his ideas of existentialism by emphasizing the ethical dimensions of living authentically. In her work 'The Ethics of Ambiguity,' she explores how individuals can navigate the freedom and responsibility Sartre describes, while also considering the impact of their choices on others. Beauvoir's approach builds upon Sartre's existentialism by integrating a more comprehensive ethical framework, addressing the moral implications of living a good life in a world without predefined essence.
Existentialism / Feminist philosophy
Simone de Beauvoir
1908 CE - 1986 CE
Simone de Beauvoir suggests living a good life involves embracing existential freedom and responsibility. To be happy, one should actively pursue their passions and create a world that reflects their values, even amidst uncertainty. This involves making choices that align with one's authentic desires, rather than conforming to societal expectations or seeking external validation. Beauvoir emphasizes the importance of "radical freedom," where existence precedes essence, meaning individuals must define their own purpose and values. To avoid unhappiness, one should steer clear of nihilism and bad faith, which deny freedom and responsibility. Instead, accept life's ambiguity and the inherent risks of freedom, while fostering meaningful relationships and contributing to the freedom of others. By doing so, one can find satisfaction and fulfillment in the continuous project of self-creation and world-building.
Challenge
Albert Camus
Albert Camus, while sharing existentialist roots with Beauvoir, diverged in his philosophy by emphasizing the absurdity of life and the futility of searching for inherent meaning.

Sartre's concept of 'bad faith' complements Beauvoir's idea of embracing ambiguity and taking responsibility for one's actions.
Absurdism / Existentialism
Albert Camus
1913 CE - 1960 CE
Albert Camus suggests living a good life involves embracing the absurdity of existence and finding happiness in the present moment. To achieve this, one should avoid "philosophical suicide," which includes relying on religion or other comforting illusions that promise meaning or happiness in an afterlife. Instead, Camus encourages us to be aware of our mortality, as this awareness motivates us to savor our limited time. He advises living authentically by accepting life's absurdity and resisting the temptation to search for a definitive meaning or purpose. Camus emphasizes the importance of engaging in everyday pleasures, such as enjoying a cup of coffee or spending time with friends, as these small acts of presence and appreciation can lead to genuine happiness. By focusing on the here and now, and acting despite life's inherent meaninglessness, we can live a fulfilling and liberated life.
Challenge
Jean-Paul Sartre
Jean-Paul Sartre, a leading existentialist, challenged Camus's notion of absurdism by emphasizing the role of individual freedom and choice in creating meaning. Sartre believed that humans are condemned to be free and must take responsibility for their actions to construct their own essence, whereas Camus focused on the acceptance of life's inherent absurdity without seeking external meaning. Sartre's existentialism posits that individuals can transcend absurdity through conscious decision-making, contrasting with Camus's view that one must embrace the absurd without false hope.

Viktor Frankl
Viktor Frankl, a Holocaust survivor and psychiatrist, built upon Camus's ideas by proposing that meaning can be found even in the face of suffering and absurdity. In his book 'Man's Search for Meaning,' Frankl argued that individuals could find purpose through their responses to life's challenges, aligning with Camus's idea of living in spite of absurdity. Frankl's logotherapy suggests that meaning is a personal quest, which complements Camus's notion of embracing life's absurdity while actively engaging with it.
Post-structuralism / Genealogy
Michel Foucault
1926 CE - 1984 CE
Michel Foucault suggests living a good life involves engaging in "technologies of the self," which are practices that allow individuals to shape their own identities and lives. To be happy, one should focus on creating an "aesthetics of existence," where life is treated as a work of art, emphasizing personal choice and self-imposed standards. This involves cultivating self-awareness, questioning societal norms, and resisting oppressive power structures. Foucault advises avoiding passivity and the uncritical acceptance of sovereign power, which historically operates through violence and deduction. Instead, embrace disciplinary power that fosters life and individuality. By actively shaping one's life and challenging existing power dynamics, individuals can achieve a beautiful and fulfilling existence.
Challenge
Judith Butler
Judith Butler challenges Foucault's ideas by critiquing the ways in which societal norms and power structures shape individual identity and the pursuit of happiness. Butler's theory of performativity suggests that identity is not a fixed essence but is continuously constructed through repeated social performances.

Judith Butler suggests that living a good life in a world marked by inequality and exploitation requires embracing collective responsibility and interdependence. To be happy and lead a good life, one should actively engage in ethical cohabitation, recognizing that our lives are intertwined with others. This involves resisting systemic injustices and fostering conditions of livability for all, which Butler terms "precarity." Avoiding complicity in structures that perpetuate inequality is crucial, as is challenging norms that render some lives ungrievable or unworthy. Butler emphasizes the importance of performative acts of assembly and solidarity, advocating for a life lived with others, where mutual recognition and support are central. In essence, a good life is one that actively seeks to dismantle barriers to equality and embraces the ethical imperative of living together on equitable terms.
Challenge
Augustine of Hippo
Judith Butler's ideas challenge Augustine's notion of individual will as the source of moral action. Augustine believed that the power to will good or evil resides within the individual, whereas Butler emphasizes the social and political structures that shape our lives and limit our ability to lead a good life. Butler's focus on precarity and the ethics of cohabitation contrasts with Augustine's introspective approach, highlighting the external factors that influence moral choices.
Michel Foucault
Judith Butler's work challenges Foucault's theories by emphasizing the role of social norms and power structures in foreclosing the possibility of a good life for many. While Foucault focused on the ways power shapes subjectivity, Butler extends this analysis to consider how these structures create precarious conditions that affect the livability of life. Her emphasis on performativity and precarity critiques Foucault's ideas by highlighting the ethical implications of living within these constraints.
Build Upon
Theodor Adorno
Judith Butler's lecture 'Can One Lead a Good Life in a Bad Life?' directly engages with Adorno's aphorism 'Es gibt kein richtiges Leben im falschen' ('Wrong life cannot be lived rightly'). Butler builds upon Adorno's idea by exploring the moral implications of living a good life amidst systemic inequality and exploitation. Adorno's work provides a philosophical foundation for Butler's inquiry into the possibility of morality in a flawed world.
Hannah Arendt
Judith Butler's exploration of living a good life in a bad life resonates with Hannah Arendt's ideas about the public realm and the importance of collective action. Butler's emphasis on living a life with others and the role of collective movements like Occupy and Black Lives Matter builds upon Arendt's notion that political action and public engagement are essential for a meaningful life. Arendt's historical context of totalitarianism and the need for public discourse informs Butler's approach to contemporary social movements.
