Quote by Thales of Miletus: “Water is the best.”

This concise statement reflects Thales' foundational belief that water is the primary substance from which all things originate and are composed. It represents an early attempt to identify a single, underlying principle of the universe, a key step in the development of scientific thought and natural philosophy.

As one of the earliest known natural philosophers, Thales sought to explain the cosmos using natural, rather than mythological, explanations. His theory that water was the fundamental element was a groundbreaking idea for understanding the physical world.

Greek philosopher and mathematician from Miletus, active around 600 BCE, considered by Aristotle and others as the first philosopher in the Western tradition. He sought natural rather than supernatural explanations for the world. No writings by him survive; his ideas are known only through later accounts.
