As Plato later developed into a man by going throughout his own ways and experiences, he seem to learn a lot. Scholars, writers, and some of Athens finest educators structured most of Plato’s life. I believe the war and meeting Socrates during his lifetime made him who he is today. Without those two significant events occurring then Plato would not be Plato for he learned a good majority of his dialogue from Socrates. Those two to me seem to mold his life significantly than most of some of the other things done during his time. The other significant event was the Peloponnesian War between Athens and Sparta. The defeat of Athens ended its democracy, which the Spartans replaced with an oligarchy. After the oligarchy was overthrown and democracy was restored, Plato briefly considered a career in politics, but the execution of Socrates in 399 B.C.E. soured him on this idea and he turned to a life of study and philosophy.
