Meaning

Truth names what the account aims to get right; persuasion names a person’s resulting stance or the activity of bringing another to it.

Use in the book

Socrates refuses praise that makes its subject seem splendid regardless of truth. When Agathon yields to him personally, he distinguishes refuting Socrates from contradicting truth. At the end he attributes the doctrine to Diotima, declares himself persuaded and undertakes to persuade others. The speech therefore offers both reasons and a reported commitment. Persuasion is not silently equated with proof, nor is the attribution to another speaker a denial of Socrates’ endorsement.
