"Surely not! Surely we may choose what we hold to be bad."
"I doubt it"
"But how then do you account for what you call bad men?"
"I should say they are men who choose what I think bad but they think good."
"But are there not men who deliberately choose what they think bad, like Milton's Satan—'Evil be thou my Good'?"
"Yes, but by the very terms of the expression he was choosing what he thought good; only he thought that evil was good."
"But that is a contradiction."
"Yes, it is the contradiction in which he was involved, and in which I believe everyone is involved who chooses, as you say, the Bad. To them it is not only bad, it is somehow also good."
"Does that apply to Nero, for example?"
"Yes, I think it very well might; the things which he chose, power and wealth and the pleasures of the senses, he chose because he thought them good; if his choice also involved what he thought bad, such as murder and rapine and the like (if he did think these bad, which I doubt), then there was a contradiction not so much in his choice as in its consequences. But even if I were to admit that he and others have chosen and do choose what they believe to be bad, it would not affect the point I want to make. For to choose Bad must be, in your view, as absurd as to choose Good; since, I suppose, you do not believe, that our opinions about the one have any more validity than our opinions about the other. So that if we are to abandon Good as a principle of choice, it is idle to say we may fall back upon Bad."
