Fra hans bog Studies in Classic American Literature, kapitel 8:
Man should never do the thing he believes to be wrong. Because if he does, he loses his own singleness, wholeness, natural honour.
If you want to do a thing, you’ve either got to believe, sincerely, that it’s your true nature to do this thing – or else you’ve got to let it alone.
Believe in your own Holy Ghost. Or else, if you doubt, abstain.
A thing that you sincerely believe in cannot be wrong, because belief does not come at will. It comes only from the Holy Ghost within. Therefore a thing you truly believe in, cannot be wrong.
