Transcript: Plato was a disciple of Socrates. He founded the world’s first university in an olive grove outside Athens in 387 BC. Plato was a hugely influential philosopher. He was a rationalist. He believed that we could conceive of the natural world and the way the universe works entirely in theory within our own heads. He believed that the observational phenomenon of the world were unreliable representations of what was truly going on. So Plato was not a scientist in the modern sense. However, his creation of a university, a place where people could think deeply about mathematics and logic, spurred Greek science onward. Written over the portal of Plato’s academy were the words, “Let none but Geometers enter here.”
