Appendix A: Glossary of Key Philosophical Terms

This glossary defines approximately 90 key philosophical terms used throughout Practical Philosophy: How to Live. Definitions are written for readers without prior philosophy training: they prioritize genuine understanding over technical precision. Where a term carries different meanings in different traditions, both usages are noted. Cross-references point to the chapters where each term is most fully developed.

Terms from all traditions represented in the book are included — Western analytical, continental, Buddhist, Hindu, Daoist, Confucian, African, and Indigenous philosophies. No tradition is treated as primary; terms are listed alphabetically throughout.

A

A posteriori (Latin: "from what comes after") Knowledge derived from experience — from what we observe, feel, or encounter in the world. The claim "water boils at 100°C at sea level" is a posteriori because it depends on empirical observation. Contrasted with a priori. Associated with empiricist philosophers including Hume and Locke. See Chapters 21, 22.

A priori (Latin: "from what comes before") Knowledge that can be known through reason alone, independent of experience. Mathematical truths ("2 + 2 = 4") and logical tautologies are classic examples. Kant argued some moral knowledge is also a priori. Contrasted with a posteriori. See Chapters 21, 22.

Absurdism The philosophical position, associated with Albert Camus, that human beings inevitably seek meaning and rational order in a universe that offers neither. The "absurd" is the gap between our hunger for meaning and the universe's silence. Camus argued we should neither deny the absurd nor give up — but live in defiant embrace of it. Distinct from nihilism, which abandons the search for meaning entirely. See Chapters 10, 15, 33.

Akrasia (Greek: "lack of self-mastery") Acting against one's better judgment — doing what one knows is wrong or unwise. Aristotle was puzzled by akrasia: if you know what is good, why would you choose otherwise? The phenomenon points to the gap between moral knowledge and moral action, and raises questions about the nature of weakness of will. See Chapters 5, 8, 11, 35.

Amor fati (Latin: "love of fate") Nietzsche's concept of loving one's fate — not merely accepting or tolerating what happens, but wholeheartedly affirming it. Amor fati asks us to will that every moment of our lives recur eternally. This is not passive resignation but active embrace of existence as it is. Connects to the Stoic practice of accepting what one cannot control. See Chapters 11, 33.

Anattā (Pali: "no-self") The Buddhist teaching that there is no permanent, unchanging self or soul. What we call the "self" is a collection of changing processes — sensations, perceptions, mental formations, consciousness — with no fixed core. Realizing anattā is central to Buddhist liberation: clinging to a non-existent permanent self is a root cause of suffering. See Chapters 14, 29, 32.

Anicca (Pali: "impermanence") The Buddhist teaching that all conditioned phenomena are impermanent — they arise, change, and pass away. Anicca applies to physical things, mental states, relationships, and the self itself. Failure to accept impermanence is a primary cause of suffering (dukkha). Contemplating anicca is a key Buddhist meditation practice. See Chapters 14, 19, 29.

Aporia (Greek: "impasse" or "puzzlement") A state of genuine philosophical perplexity — being at a loss, unable to answer a question you thought you understood. The Socratic dialogues frequently end in aporia: interlocutors discover they cannot define justice, virtue, or piety as confidently as they supposed. Socrates treated aporia not as failure but as the beginning of genuine inquiry. See Chapters 2, 3.

Atman (Sanskrit: "self" or "soul") In Hindu philosophy, the true self — the innermost essence of a person that is not identical with body, mind, or ego. In Advaita Vedanta (Shankaracharya), Atman is ultimately identical with Brahman, the universal reality. In Dvaita Vedanta (Madhva), Atman is distinct from Brahman but dependent on it. The nature of Atman is one of the great dividing questions of Hindu philosophy. See Chapters 27, 32.

Authenticity The quality of living in accordance with one's genuine self, values, and choices — as opposed to conforming to social pressure, playing roles, or acting in "bad faith." Existentialists (Sartre, Heidegger, Kierkegaard) emphasized authenticity as a central ethical demand. It does not mean selfishness or ignoring others, but refusing to let external forces dictate who one is. See Chapters 13, 15, 33.

B

Bad faith (mauvaise foi, French) Sartre's term for the self-deceptive flight from freedom. Bad faith means pretending that one has no choice, that social roles or circumstances determine who one must be. A waiter who acts as though the role of "waiter" is his entire identity is in bad faith: he is a human being who has chosen to be a waiter, and could choose otherwise. Bad faith is not the same as lying to others — it is lying to oneself about one's freedom. See Chapters 13, 15, 33.

Brahman (Sanskrit) In Hindu philosophy, the universal, ultimate reality — the ground of all being. In Advaita Vedanta, Brahman is the sole reality; everything else is maya (illusion or appearance). In Vishishtadvaita (Ramanuja), the world and souls are real but exist within Brahman as its body. The nature of Brahman — personal or impersonal, identical with the self or distinct — is central to the divisions within Hindu philosophical traditions. See Chapters 27, 32.

C

Care ethics A moral framework emphasizing relationships, responsibilities arising from particular bonds, and the value of care and responsiveness to needs. Developed by Carol Gilligan and Nel Noddings as a critique of impartialist moral theories (Kantian and utilitarian) that treat all moral situations as equivalent. Care ethics argues that our obligations to those close to us — family, friends, dependents — are not the same as our obligations to strangers. See Chapters 6, 12.

Categorical imperative Kant's supreme principle of morality: act only according to that maxim by which you can at the same time will that it should become a universal law. Unlike hypothetical imperatives ("do X if you want Y"), the categorical imperative commands unconditionally. Kant offered several formulations, including: treat humanity never merely as a means but always also as an end. See Chapters 6, 8.

Cogito ergo sum (Latin: "I think, therefore I am") Descartes' foundational philosophical claim. After methodically doubting everything, Descartes found one thing that could not be doubted: the very act of doubting proved that something was doing the doubting. This "something" is a thinking thing — a mind. The cogito became the starting point for modern Western philosophy's emphasis on the individual knowing subject. See Chapters 21, 24.

Compatibilism The view that free will and determinism are compatible — that we can be free even in a deterministic universe. Compatibilists typically define freedom not as the ability to have done otherwise in exactly the same circumstances, but as the ability to act according to one's own reasons and desires without external coercion. The dominant position among contemporary philosophers of action. See Chapter 16.

Consequentialism The family of moral theories holding that the rightness of an action is determined entirely by its consequences. The most famous version is utilitarianism (Bentham, Mill), which holds that we should maximize overall well-being. Consequentialism is intuitively appealing but faces hard questions: whose consequences count? How far into the future? Does it permit monstrous acts for good outcomes? See Chapters 5, 9.

D

Dao (Chinese: "the Way") The central concept of Daoist philosophy — the underlying natural order or principle of the universe. The Dao cannot be fully defined or named (as the Dao De Jing begins: "The Dao that can be told is not the eternal Dao"). It is the source and pattern of all things, characterized by spontaneity (ziran) and paradox. Humans flourish by aligning themselves with the Dao rather than forcing their will against it. See Chapters 28, 34.

Dasein (German: "being there") Heidegger's term for the kind of being that humans are — entities for whom their own existence is always in question, who are always already in a world, and who exist in relation to their own mortality (being-toward-death). Dasein is not a mind enclosed in a body but a being-in-the-world: always situated, always temporal, never simply a neutral observer. See Chapters 16, 24, 33.

De (Chinese: "virtue," "power," or "potency") In Daoist philosophy, the natural virtue or potency of a thing when it fully expresses its own nature in alignment with the Dao. A tree has de when it grows freely according to its nature; a person has de when they act without forcing, pretension, or striving against what is natural. De is not moral virtue in the Western sense but something more like authentic presence or natural efficacy. See Chapter 34.

Deontology (from Greek: deon, duty) The family of moral theories holding that certain actions are intrinsically right or wrong, regardless of their consequences. Kant's ethics is the paradigmatic deontological theory. Deontologists typically invoke duties, rights, and constraints: you must keep promises, must not lie, must not use people merely as means — even if breaking the rule would produce better outcomes. See Chapters 6, 8.

Dharma (Sanskrit) A central concept in Hindu, Buddhist, and Jain traditions, with several related meanings: (1) the cosmic order or natural law; (2) one's social or caste duty (varna-dharma); (3) in Buddhism, the teachings of the Buddha; and (4) righteous conduct in general. Understanding and fulfilling one's dharma is a key to living well in many South Asian philosophical traditions. Context is essential for determining which meaning is operative. See Chapters 29, 32.

Dialectic (from Greek: dialektikē, "the art of conversation") A method of philosophical inquiry through structured opposition. In Socrates and Plato, dialectic is the back-and-forth of question and answer that moves toward truth by exposing and resolving contradictions. In Hegel, dialectic describes the triadic movement of thesis, antithesis, and synthesis by which Spirit unfolds through history. In everyday usage, dialectical reasoning means holding opposing ideas in tension and working through their contradiction. See Chapters 2, 3, 21.

Dukkha (Pali: "suffering," "unsatisfactoriness," or "dis-ease") The first of the Buddhist Three Marks of Existence and the starting point of the Four Noble Truths. Dukkha encompasses obvious pain and suffering but also the subtler sense that conditioned existence is inherently unsatisfying — even pleasures end, achievements disappoint, relationships are impermanent. Buddhism is not pessimistic about dukkha but diagnostic: its cause can be understood and its cessation is possible. See Chapters 14, 29.

E

Empiricism The epistemological view that all knowledge derives from sensory experience. Empiricists (Locke, Hume, Berkeley) argued against innate ideas: the mind begins as a blank slate, and concepts arise from what we encounter in experience. Contrasted with rationalism, which holds that reason alone can yield genuine knowledge. Modern science embodies empiricist commitments. See Chapters 21, 22.

Epistemology (from Greek: episteme, knowledge, + logos, study) The branch of philosophy concerned with the nature, sources, and limits of knowledge. Central epistemological questions: What is knowledge? How do we distinguish knowledge from mere belief? What can we know and what are we uncertain about? Is knowledge possible at all (skepticism)? See Chapters 21–26.

Epistemic injustice Miranda Fricker's term for the distinctive wrong done to someone in their capacity as a knower. Two main forms: testimonial injustice (crediting someone's testimony less than it deserves because of identity prejudice) and hermeneutical injustice (a gap in collective understanding that puts someone at an unfair disadvantage when making sense of their experience). See Chapters 12, 21, 36.

Eternal recurrence Nietzsche's thought experiment: what if you had to live your life, in all its exact details, infinitely many times over? Would you embrace it or cringe from it? Nietzsche uses eternal recurrence not as a cosmological claim but as a test of affirmation: can you love your life enough to will its infinite repetition? Connected to amor fati. See Chapter 11.

Eudaimonia (Greek: "flourishing," "happiness," "living well") Aristotle's term for the highest human good — not mere pleasure or subjective satisfaction, but the active exercise of one's distinctively human capacities in accordance with virtue. Often translated as "happiness" but better understood as flourishing or thriving. Eudaimonia is the end toward which all human action ultimately aims, according to Aristotle. See Chapters 5, 7, 35.

Existentialism A philosophical movement (20th century) emphasizing individual existence, freedom, and the responsibility to create meaning in a universe without given purpose. Key claims: existence precedes essence (humans are not born with a fixed nature or purpose); we are "condemned to be free" (Sartre); we must face anxiety, death, and the absurd honestly. Major existentialists: Kierkegaard, Heidegger, Sartre, Camus, Beauvoir. See Chapters 13, 15, 16, 33.

F

Facticity Sartre's term for the fixed, given aspects of one's situation — one's past, one's body, one's social position, one's history. Facticity is real and cannot simply be wished away, but it does not determine what one does with it. Freedom consists in how one projects forward from one's facticity. The tension between facticity and freedom is a central existentialist theme. See Chapter 33.

Feminist philosophy Philosophy that examines how gender structures knowledge, experience, ethics, and political life, and that takes seriously the perspectives and experiences of women and other marginalized genders. Feminist philosophers have critiqued traditional philosophy's pretensions to universality while actually centering male experience; developed distinctive accounts of knowledge, ethics, and embodiment; and connected philosophy to political projects of liberation. See Chapters 12, 21, 36.

Functionalism (philosophy of mind) The view that mental states are defined not by their physical substrate but by their functional role — what they do, what causes them, and what they cause in turn. A belief is a mental state that represents the world in a certain way and, together with desires, produces action. Functionalism allows that very different physical systems (silicon chips, biological neurons) could realize the same mental states. See Chapter 24.

G

Gettier problem Edmund Gettier's 1963 refutation of the traditional definition of knowledge as "justified true belief." Gettier constructed cases in which someone has a true, justified belief but does not seem to have knowledge — because their justification is accidentally connected to the truth. The Gettier problem sparked decades of work on what knowledge actually is. See Chapter 21.

H

Hard problem of consciousness David Chalmers' term for the question of why physical brain processes give rise to subjective experience — why there is "something it is like" to see red or feel pain. The "easy problems" of consciousness concern explaining cognitive functions (attention, discrimination, reporting states). The hard problem asks why any of this physical processing is accompanied by experience at all. Many philosophers consider it the deepest unsolved problem in philosophy. See Chapter 24.

Hermeneutics The theory and method of interpretation, especially of texts, symbols, and practices. Originally developed for interpreting scripture and legal texts, hermeneutics was expanded by Heidegger and Gadamer into a general account of how understanding works. Key insight: we always interpret from within a tradition and horizon; no interpretation is presuppositionless. See Chapters 3, 25, 36.

Hermeneutical injustice A form of epistemic injustice (Fricker) in which a gap in collective interpretive resources disadvantages a person trying to understand their own experience. A woman who cannot name what is happening to her as "sexual harassment" (before the concept existed) suffers hermeneutical injustice: the conceptual resources needed to make sense of her experience are unavailable. See Chapters 12, 21.

I

Intersectionality Kimberlé Crenshaw's term for the way multiple systems of oppression (race, gender, class, sexuality) interact and compound one another, creating experiences that cannot be understood by examining any single axis of identity in isolation. A Black woman's experience is not simply "Black experience" plus "women's experience" but something qualitatively distinct. See Chapters 12, 36.

K

Karma (Sanskrit/Pali: "action") In Hindu and Buddhist traditions, the principle that intentional actions have consequences for the acting subject — consequences that may extend across multiple lifetimes (in traditions accepting rebirth). Karma is not fate or cosmic punishment but causal consequence: certain actions reliably produce certain results in one's character and circumstances. Ethical living is partly about cultivating good karma. See Chapters 29, 32.

L

Language games (Sprachspiele) Wittgenstein's term (in Philosophical Investigations) for the diverse practices in which language is used. Different language games (greeting, ordering, reporting, joking, praying) have different rules and purposes; meaning arises from use within a game, not from words corresponding to inner mental states or external objects. Philosophy goes wrong when it treats language as if there were one uniform game. See Chapters 3, 25.

Li (Chinese: "ritual propriety," "rites," or "pattern") A central concept in Confucian philosophy — the forms and practices of proper social conduct, including rituals, etiquette, roles, and ceremonies. Li is not mere etiquette but the structured forms through which human relationships are enacted and maintained. Practicing li cultivates ren (humaneness) and constitutes a well-ordered social life. See Chapter 31.

Logos (Greek: "reason," "word," "rational order") In Stoic philosophy, the rational principle that orders the cosmos — the divine reason permeating and structuring all of nature. Human reason is a fragment of the divine logos. Living in accordance with logos means living according to reason and nature, which is the Stoic goal. The concept was also taken up in Christian philosophy (John's Gospel: "In the beginning was the Word/Logos"). See Chapters 7, 28.

M

Maya (Sanskrit: "illusion" or "appearance") In Advaita Vedanta, the power by which Brahman (ultimate reality) appears as the multiplicity of the world. Maya does not mean the world is unreal in the sense of non-existent, but that it lacks ultimate, independent reality — it is a dependent appearance of Brahman. Removing the veil of maya through philosophical inquiry and practice (jnana yoga) leads to liberation. See Chapter 32.

Metaphysics The branch of philosophy concerned with the most fundamental questions about the nature of reality: What exists? What kinds of things are there? What is the relationship between mind and matter? What is time? What is causation? Often divided into ontology (the study of being) and cosmology (the nature of the universe). See Chapters 13, 16, 24.

Mitákuye Oyásʼiŋ (Lakota: "All Are Related" or "We Are All Related") A Lakota prayer and philosophical principle expressing the relational understanding that all beings — human, animal, plant, mineral, spiritual — exist in fundamental kinship and interdependence. It challenges individualist ontologies by placing relationship and reciprocity at the foundation of existence. See Chapters 30, 35.

Moksha (Sanskrit: "liberation" or "release") In Hindu philosophy, liberation from the cycle of birth, death, and rebirth (samsara) — the ultimate spiritual goal. Moksha involves recognizing the true nature of Atman and its relation to Brahman (depending on the tradition: identity, intimate union, or loving relationship). The four classical paths to moksha are jnana yoga (knowledge), bhakti yoga (devotion), karma yoga (action), and raja yoga (meditation). See Chapter 32.

Moral luck The disturbing phenomenon that our moral assessments — how much we praise or blame, how seriously we judge — are partly determined by factors outside anyone's control. Two reckless drivers both run a red light; one kills a pedestrian, the other doesn't. Are they equally culpable? Most people's reactions suggest not — but they had identical intentions and identical control over their actions. Moral luck is a puzzle about the relationship between control, responsibility, and moral assessment. See Chapters 9, 11.

Moral realism The view that there are objective moral truths — facts about right and wrong that hold independently of what anyone thinks or feels. Contrasted with moral relativism (moral truths are relative to cultures or individuals) and moral anti-realism (there are no moral facts, only attitudes or expressions). See Chapters 4, 9.

N

Narrative identity The view (developed by Paul Ricoeur and others) that personal identity is constituted through the stories we tell about ourselves — our lives have unity and meaning insofar as we can understand them as narratives with characters, plots, and arcs. Narrative identity is not fixed but actively constructed and reconstructed across time. See Chapters 14, 25.

Nihilism (from Latin: nihil, nothing) The view that life has no inherent meaning, purpose, or value. Nietzsche diagnosed nihilism as the consequence of the "death of God" — when traditional sources of meaning collapse, nothing takes their place. Nietzsche did not endorse nihilism but saw it as a crisis to be overcome through new affirmations of value. Distinguished from absurdism: the absurdist does not conclude that life is meaningless, only that the universe offers no given meaning. See Chapters 11, 13, 15.

Nirvana (Sanskrit/Pali: "extinguishing" or "blowing out") In Buddhism, the liberation from suffering achieved through the extinction of craving, aversion, and delusion. Nirvana is not annihilation of the self but the cessation of the clinging and grasping that constitute the constructed self and perpetuate suffering. In Theravada Buddhism, nirvana is the goal of practice; in Mahayana, the bodhisattva postpones nirvana to help others achieve liberation. See Chapters 14, 29.

O

Ontology (from Greek: ontos, being, + logos, study) The branch of metaphysics concerned with the nature and categories of being — what it means to exist, and what kinds of things exist. Questions include: Do abstractions (numbers, justice) exist? What is the relationship between substance and property? Is existence a real predicate? Ontology underlies many philosophical disputes in ethics, epistemology, and philosophy of mind. See Chapters 16, 24, 30.

P

Phronesis (Greek: "practical wisdom") Aristotle's term for the intellectual virtue of knowing how to act well in particular situations — the capacity to discern the right thing to do in context, weighing competing goods and circumstances. Phronesis is not a rule-following procedure but a cultivated sensibility. It is the master virtue that guides all the others. See Chapters 5, 7, 35.

Pragmatism The American philosophical tradition (Peirce, James, Dewey) holding that the meaning of ideas lies in their practical consequences, and that truth is what works — what enables successful action and inquiry. Pragmatism rejected abstract metaphysics in favor of concrete problems and their solutions. In ethics, pragmatism emphasizes experimental, context-sensitive approaches to moral questions. See Chapters 21, 26.

Prohairesis (Greek: "moral purpose" or "the will") Epictetus's term for the faculty of choice — the one thing that is truly "up to us." Prohairesis is the power to assent or refuse to assent to impressions, and to form and act on intentions. Stoic freedom consists in cultivating prohairesis: choosing one's responses, values, and commitments even when circumstances are outside one's control. See Chapters 7, 28.

Q

Qualia (Latin plural of quale, "what it is like") The subjective, felt qualities of conscious experience — the redness of red, the painfulness of pain, the taste of coffee. Qualia are often invoked in discussions of the "hard problem" of consciousness: even if we could fully explain the neural processing underlying perception, have we explained why it feels like something? See Chapter 24.

R

Rationalism The epistemological view that reason, rather than sensory experience, is the primary source of genuine knowledge. Rationalists (Descartes, Spinoza, Leibniz) argued that the mind has innate ideas or can derive truths through pure reason. Mathematical knowledge is the paradigm case. Contrasted with empiricism. See Chapters 21, 22.

Ren (Chinese: "humaneness," "benevolence," "love") The central virtue in Confucian ethics — the quality of genuine care, sensitivity, and responsiveness to others that is constitutive of full humanity. Ren is not merely kindness but a cultivated capacity for human-heartedness, expressed through right relationships and proper conduct (li). Confucius described ren as the master virtue from which all others flow. See Chapter 31.

Relational ontology The philosophical view that entities (persons, beings, things) are fundamentally constituted by their relations to others, rather than existing as independent substances that then enter into relations. Central to Indigenous, African, and many Asian philosophical traditions. Contrasted with the Western liberal tradition's starting point of the autonomous individual. See Chapters 29, 30, 31, 35.

S

Skepticism The philosophical stance that questions whether knowledge is possible in a given domain. Radical skepticism doubts all knowledge claims (Descartes' method of doubt). Moderate skepticism is more targeted: we might know everyday facts but not theoretical entities, or not facts about other minds. Skepticism is often a methodological tool rather than a final conclusion. See Chapters 21, 22.

Standpoint epistemology The view that knowledge is shaped by the social position of the knower, and that marginalized standpoints may offer distinctive epistemic advantages (seeing aspects of social reality that those in privileged positions cannot see). Associated with feminist philosophers including Patricia Hill Collins, Sandra Harding, and Dorothy Smith. See Chapters 12, 21.

Stoicism The ancient Greek and Roman philosophical school (founded by Zeno of Citium, developed by Epictetus, Marcus Aurelius, and Seneca) that holds: virtue is the only genuine good; events outside one's control are indifferent; freedom lies in disciplining one's judgments and desires; and the universe is governed by rational order (logos). Modern Stoicism has become influential in psychotherapy (CBT) and personal development. See Chapters 7, 28.

Superogation Going beyond what morality requires — actions that are praiseworthy but not obligatory. Giving your kidney to a stranger is supererogatory. Moral theories differ about how much weight supererogation carries: strict consequentialism struggles to make sense of the concept (if a good act is possible, shouldn't you do it?), while deontological theories typically recognize a sphere of permitted but non-required action. See Chapter 9.

T

Testimonial injustice A form of epistemic injustice (Fricker) in which a speaker's testimony is given less credibility than it deserves because of identity prejudice — their race, gender, class, or other social markers. Testimonial injustice wrongs the person not just as an agent but in their fundamental capacity as someone whose word counts. See Chapters 12, 21.

Thought experiment A philosophical method involving imagining a hypothetical scenario to test or illuminate a philosophical principle. Famous examples: Plato's Cave, the Trolley Problem, the Chinese Room, Rawls's Veil of Ignorance, Parfit's teleporter. Thought experiments isolate variables in ways real cases cannot, but their results depend on intuitions that may themselves be questionable. See Chapters 3, 6, 9, 24.

Thrownness (Geworfenheit) Heidegger's term for the fact that we find ourselves already in a world — a particular time, place, body, language, culture — without having chosen it. We are "thrown" into our existence. Authenticity does not mean escaping thrownness (impossible) but owning it: taking up one's situation as one's own rather than fleeing from it into "the They." See Chapters 16, 33.

U

Ubuntu (Nguni Bantu: "I am because we are") A central concept in many southern and central African philosophical traditions: personhood is constituted through relationships and community. To be human is to be human through others. Ubuntu ethics emphasizes communal solidarity, interdependence, and the shared humanity that grounds moral obligations. Associated with philosophers including Kwasi Wiredu, Mogobe Ramose, and Desmond Tutu. See Chapters 30, 35.

Upanishads Ancient Indian philosophical texts (composed roughly 800–200 BCE) forming the philosophical heart of the Hindu canon. The Upanishads move beyond Vedic ritual to ask fundamental metaphysical questions: What is the ultimate reality (Brahman)? What is the self (Atman)? How are they related? The statement "Tat tvam asi" (That thou art) — Brahman and Atman are one — is the Upanishadic key to liberation. See Chapter 32.

Utilitarianism The specific consequentialist theory (Bentham, Mill) that the right action is the one that produces the greatest happiness for the greatest number. Classical utilitarianism equates "good" with pleasure or preference-satisfaction. Rule utilitarianism refines the view: follow rules that, generally followed, produce the best outcomes. Faces objections about justice (it seems to permit sacrificing the few for the many) and about the measurement of happiness. See Chapters 5, 9.

V

Veil of ignorance Rawls's thought experiment for determining principles of justice: imagine you are choosing the basic structure of society without knowing your place in it — your class, race, gender, talents, or conception of the good. What principles would rational persons choose from behind this "veil"? Rawls argued they would choose equal basic liberties and the "difference principle" — inequalities are just only if they benefit the least advantaged members of society. See Chapters 10, 36.

Virtue ethics The family of moral theories that centers character and human excellence rather than rules or consequences. The right action is what a virtuous person — one of practical wisdom, courage, justice, temperance — would do in the circumstances. Associated with Aristotle, the Stoics, Confucians, and contemporary thinkers including Alasdair MacIntyre and Martha Nussbaum. See Chapters 5, 7, 35.

W

Wu wei (Chinese: "non-action" or "effortless action") The Daoist principle of acting in accordance with the natural flow of the Dao rather than forcing or straining against it. Wu wei does not mean passivity or doing nothing, but acting with minimal interference — like water finding its natural path downhill. The best governance, craftsmanship, and living all exemplify wu wei. See Chapter 34.

Y

Yi (Chinese: "righteousness," "duty," "moral obligation") One of the four cardinal Confucian virtues alongside ren (humaneness), li (ritual propriety), and zhi (wisdom). Yi refers to doing what is appropriate and right in one's relationships and social roles — acting from a sense of duty rather than personal advantage. Mencius argued that the moral sprout of yi is innate: even small children feel a sense of shame when they do wrong. See Chapter 31.

Z

Zhuangzi (also: Ziran, Chinese: "so of itself," "spontaneity," "naturalness") Ziran in Daoist thought means the self-so, the way things naturally are when not forced or interfered with. Each thing's ziran is its authentic way of being. The Daoist sage cultivates ziran — living according to one's natural rhythms and the rhythms of the cosmos. Zhuangzi is also the name of the philosopher (c. 369–286 BCE) and the text bearing his name, one of the foundational Daoist works, known for its humor, paradox, and extraordinary literary imagination. See Chapters 28, 34.

A note on language: This glossary transliterates terms from Pali, Sanskrit, Chinese, Greek, and Latin using standard romanization systems without diacritical marks in most cases. Readers interested in precise pronunciation and original scripts are encouraged to consult the further reading guide (Appendix G) for scholarly editions that use full diacritical notation.
