Greek philosophy started in about 600 BCE. Before Socrates, there were three early thinkers that lived in Miletus: Thales, Anaximander, and Anaximenes. They all believed that everything came from "primal substance" but they could not agree what it was. Greek philosophy asks the think about the meaning of life, character and traits, and about nature.
Socrates is considered the father of Western philosophy. Most of the facts that we know about him are from accounts from his students, like Plato. Instead of giving answers like normal teachers, he would ask them instead. Before Socrates became a philosopher, he served in the military as the armored Infantry. He went around Athens, teaching and gathering students. Many people didn't like the way Socrates taught, so he was sentenced to death by drinking poison.
Plato is a very well-known philosopher of Ancient Greece and has written many important texts. He was born in 428 BCE and his parents claim to be descended from Poseidon. After the death of Socrates, his teacher, he went around traveling, and soon he established his very first school in Athens. He wrote the Republic, which tells of his way of thinking of justice, beauty, and the truth. He later died after being in his Academy for 13 years.
Aristotle was perhaps one of the greatest philosophers in history. It is believed that his parents died when he was very young, and he was changed by the Macedonian court till his death. Aristotle had an older sister, and her husband was Aristotle's guardian until 17. He enrolled in Plato's Academy, and not long after, he was teaching Alexander the Great. He became very close to Alexander and Philip and he created his own school, the Lyceum. He fled to and died on the island of Euboea.
The Academy still had some ruins that are visible today.
This is modern day Athens. This is where Socrates, Plato, and Aristotle started their philosophy path.
This is one of the pages of the "Republic" by Plato. The Republic is written in many different books.
The island of Euboea was the place where Aristotle fled to avoid being persecuted and he died there.
