@tldr
Plato’s greatest lesson hides in plain sight:
If you are not willing to live like Socrates (poor, prone, and always questioning), you are not actually a “Philosopher”
You may be philosophical; you may be friendly toward philosophy; you may admire philosophers.
But mistaking yourself for a Philosopher can do a lot of harm to yourself, your city, and to real philosophy.
(This is one of the big things that’s overlooked when people implicitly equate Plato’s Socrates with Plato.)
