Greece is known for the Greek Pantheon and its myths and legends, so much so that it’s one of the most famous and influential mythologies in the world.
Socrates (l. c. 470/469-399 BC) is considered the father of Western philosophy, with his Socratic method of asking questions to get to the truth and directing philosophy away from the strict exploration of natural science to branch into morality and existentialism.
Hippocrates (c. 460 – c. 375 BC) is considered the father of western medicine. He is the first physician to posit that illness was not a punishment sent by the gods but actually a condition caused by other physical illness-creating elements, such as a bad diet.
