Full Idea
Leontius saw some corpses near the public executioner. He desired to look at them, but was disgusted and turned away. Finally he mastered his appetite and rushed to the corpses, saying 'Look for yourselves, you evil eyes, take your fill'.
Gist of Idea
A man was disgusted by corpses, but he angrily overruled his appetite
Source
Plato (The Republic [c.371 BCE], 439e)
A Reaction
[compressed] The story suggests to Socrates that anger can master appetite, so the mind must have 'spirit' [thumos], as well as reason and appetite. So the soul has three parts, not two.
