"Then you know the truth, and you recognise it when you meet with it?"
"Yes."
"But then the truth lies also outside of ourselves. Goodness, wisdom, and other excellent things are external to us, and we can only draw them out of ourselves? Have you not said that God is a projection of self?"
"A stronger self, Socrates."
"Then you recognise a standard of excellence beyond man, and this standard of excellence he draws out of himself; and that only is true which a man draws out of himself; but at the same time you recognise in others the art of cobbling and of politics."
"These things are only conventional," said Protagoras.
"Why, Protagoras? What is the difference between going as an apprentice to a good cobbler and going as an apprentice to a good man?"
"Because cobbling is an art that any one may learn, but virtue is different."
"Is virtue different from doing good?"
"No."
