We see Plato solidify his position on which of the three sections of the soul must be in control for a man to be righteous and happy. states "And what, I said, are we to suppose the philosopher to think of other pleasures than the pleasure of knowing truth and reality, and of being ever occupied with this while he learns?" This means that Plato believes that the man of reason and knowledge (like a philosopher) is the happiest, and will remain so as long as he continues to learn, since he understands the difference between necessary and unnecessary pleasures in life, and will always be busy from the "pleasure of knowing truth and reality", as Plato states in the text. In conclusion, the passage of the text sees Plato explain his belief that Reason must be the dominant part of the soul, to ensure that a person is at their happiest as a man of reason is not just about the ability to understand and finding happiness in the other parts of his soul, but also the ability to prevent useless desires from becoming illegal in his person.
