Portrait of Thales of Miletus

Thales of Miletus

c. 624-546 BC · Early Greek Thought · Prominent

Thales counts as the first Western philosopher, a Greek from Miletus around 600 BC whom his countrymen numbered among the Seven Sages. Everything is water at bottom, he guessed. The answer matters less than the move: he looked for a cause inside the world instead of naming a god, and Aristotle dates the turn from myth to reason to him. He also said that all things are full of gods.
