A dialogue between Socrates and Meno probes the subject of ethics. Can goodness be taught? If it can, then we should be able to find teachers capable of instructing others about what is good and bad, right and wrong, or just and unjust.

To answer that puzzle, Socrates questions one of Meno’s servants in an attempt to show that we know fundamental ideas by recollecting them.

Plato’s dialogues frequently cover several topics and show their connection to each other. The "Phaedrus" is a model of that skill because of its seamless progression from examples of speeches about the nature of love to mythical visions of human nature and destiny to the essence of beauty and, finally, to a penetrating discussion of speaking and writing. It ends with an examination of the love of wisdom as a dialectical activity in the human mind.
