Western Philosophy- the Big Three

I always get confused about the order that the three great Western philosophers come in, so I finally looked it up, and it's Socrates that came first, then Plato, then Aristotle; the mnemonic being SPA. 

Each was a student of the one before them, and each was inspired by the Delphic Oracle, a tiny bit of wisdom inscribed into the entrance of a temple to Appollo in Delphi, Greece, a few generations before Socrates: Know Thyself. 

This 2-word injunction, probably passed down from the Egyptians, who pre-dated the Greeks, is the foundation of Western philosophy.
