SOCRATES: Well, and in lute-playing and in flute-playing, and in all arts
and sciences, is not that mind the better which voluntarily does what is
evil and dishonourable, and goes wrong, and is not the worse that which
does so involuntarily?

HIPPIAS: That is evident.

SOCRATES: And what would you say of the characters of slaves? Should we
not prefer to have those who voluntarily do wrong and make mistakes, and
are they not better in their mistakes than those who commit them
involuntarily?

HIPPIAS: Yes.

SOCRATES: And should we not desire to have our own minds in the best state
possible?

HIPPIAS: Yes.

SOCRATES: And will our minds be better if they do wrong and make mistakes
voluntarily or involuntarily?

HIPPIAS: O, Socrates, it would be a monstrous thing to say that those who
do wrong voluntarily are better than those who do wrong involuntarily!

SOCRATES: And yet that appears to be the only inference.

HIPPIAS: I do not think so.
