Plato was a famous Greek philosopher and one of Socrates’ brightest students. Due to the fact that there are no biographical accounts from his time, we have to rely on his writings and biographies written 500 years after his death to know more about him.

As a young man, Plato studied painting, wrote poems and wrestled, until he met Socrates. That’s when he became a philosopher and wanted to pursue a career in politics. He gave up on becoming a politician after Socrates was sentenced to death, and decided to travel and learn everything he could on philosophy, mathematics, science and religion.

After 12 years of traveling and gaining knowledge, Plato returned to Greece where he founded The Academy, the first organized school in Western civilization.
