Thales and the Birth of Philosophy: What Happened
In the early 6th century BC, Thales of Miletus, a Greek city on the coast of Asia Minor, became what later Greeks regarded as the first philosopher. According to tradition, he correctly predicted a solar eclipse that occurred in 585 BC, a date often used to mark the beginning of Western philosophy. What made Thales revolutionary was his approach. Instead of explaining the world through myths about gods, he looked for natural causes that could be reasoned about and debated. He proposed that everything was ultimately made of water, a single underlying substance, an idea that launched centuries of inquiry into the basic nature of reality. Thales was also credited with practical achievements in geometry, such as measuring the height of the pyramids using their shadows, and with advising the Ionian cities on politics. His followers in Miletus, Anaximander and Anaximenes, continued his search with their own theories. Together they formed the Milesian school, the starting point of Greek philosophy and science, and Thales was later counted among the Seven Sages of Greece.
