it is only among fools that the wise are judged to be destitute of wisdom.

Context

“Socrates admits that this is true in the world as it is, but maintains that it is the other people who are to blame, not the philosophers; in a wise community the philosophers would not seem foolish; it is only among fools that the wise are judged to be destitute of wisdom. What are we to do in this dilemma? There were to have been two ways of inaugurating our Republic: by philosophers becoming rulers, or by rulers becoming philosophers. The first way seems impossible as a beginning, because in a city not already philosophic the philosophers are unpopular.” source
