Western philosophy spans 2,500 years, from Thales' declaration that 'water is the arche of all things' in 6th century BC Greece, to 21st-century analytic and postmodern thought. This article provides a concise overview of seven major philosophical epochs.
Ancient Greece is the birthplace of Western philosophy. Socrates turned philosophy from nature to the human soul, Plato constructed the world of Forms, and Aristotle founded formal logic and the theory of four causes.
Medieval philosophy centers on the relationship between faith and reason. Augustine integrated Platonism with Christian theology, while Thomas Aquinas combined Aristotle with theology in his Five Ways.
The Renaissance awakened humanism. Descartes' 'I think therefore I am' initiated the epistemological turn, while Locke's tabula rasa and Hume's skepticism on causation set the stage for Kant.
French Enlightenment thinkers championed reason against the old regime. Montesquieu proposed separation of powers, Rousseau declared 'man is born free but everywhere in chains,' and Diderot edited the Encyclopedia.
Kant's Copernican revolution in epistemology, Fichte's subjective idealism, Schelling's identity philosophy, and Hegel's absolute idealism represent the pinnacle of German classical philosophy.
Schopenhauer's will, Kierkegaard's existentialism, Marx's historical materialism, and Nietzsche's death of God mark the turbulent transition to modernity.
20th-century philosophy split into Anglo-American analytic philosophy (Frege, Russell, Wittgenstein) and Continental philosophy (Husserl, Heidegger, Sartre, Foucault, Derrida).
