- ConfuciusConfucius (traditional dates 551–479 BCE) is central to a Chinese ethical and political tradition focused less on abstract rules than on cultivating character through relationships, ritual practice, learning, and exemplary conduct.

- SocratesSocrates (c. 470–399 BCE) wrote no philosophical books. What we know comes mainly through other authors — above all Plato and Xenophon — which means “the historical Socrates” and “Plato's Socrates” cannot always be cleanly separated.
- PlatoPlato (c. 428/427–348/347 BCE) writes philosophy mainly as dialogues rather than textbooks. Socrates is often the central character, which makes Plato both a source for Socrates and a philosopher whose own views develop through dramatic argument.
- AristotleAristotle (384–322 BCE) was Plato's student, but his surviving work ranges far beyond a reaction against Plato: logic, ethics, politics, metaphysics, rhetoric, poetry, psychology, and detailed biological investigation.
- EpicurusEpicurus (341–270 BCE) is often caricatured as the philosopher of gourmet indulgence. His actual ethics is almost the reverse: the safest route to pleasure is to need less, fear less, and cultivate stable friendship and tranquility.
- René DescartesRené Descartes (1596–1650) uses methodic doubt as demolition equipment: if a belief can be coherently doubted, temporarily set it aside and ask what, if anything, remains certain.
- David HumeDavid Hume (1711–1776) pushes empiricism until familiar assumptions start looking strange. We experience sequences of events, habits, feelings, and perceptions — but where exactly do ideas such as necessary causation, enduring selfhood, or rationally guaranteed induction come from?
- Immanuel KantImmanuel Kant (1724–1804) tries to explain how objective knowledge is possible after Hume undermined the idea that necessities such as causation are simply read from experience.
- Friedrich NietzscheFriedrich Nietzsche (1844–1900) often asks a different question from “Is this moral value true?” He asks where did this value come from, what kind of life produced it, and what does it do to the people who live by it? This historical/psychological mode is his genealogical critique.
- Ludwig WittgensteinLudwig Wittgenstein (1889–1951) is unusual because his early and later work seem almost like two different philosophical projects — and the later project attacks the temptation to build theories much like the earlier one.
- Simone de BeauvoirSimone de Beauvoir (1908–1986) joins existentialist ideas about freedom with an analysis of how freedom is constrained and shaped by embodied, social, economic, and historical situations.
