In which Socrates engages Theodorus in a spirited discourse on the nature of truth, questioning the idea that man is the measure of all things and exploring the complexities of knowledge, perception, and the flux of all things.

In which the pursuit of genuine pleasure is distinguished from its shadowy imitators by reason and wisdom, revealing the philosopher’s unique experience as the measure of true delight.
