"I'd been at my desk nearly all day reading the Parmenides"
is a dialogue written by Plato, in which a young Socrates meets with two of the most famous and influential pre-Socratic Greek philosophers, Zeno
, to test Parmenides' theory that reality is singular (one), that change is impossible and existence is a unity. Socrates, challenging the older, respected thinkers, argues in favour of plurality. This dialogue is considered one of the hardest and most obscure of Plato's works.
