The Basis of Morality by Part 2 Chapter 8 Page 10

Hence it is clear that the moral responsibility of a man, while it, first of all, and obviously, of course, touches what he does, yet at bottom touches what he is; because, what he is being the original datum, his conduct, as motives arise, could never take any other course than that which it actually does take. But, however strict be the necessity, whereby, in the individual, acts are elicited by motives, it yet never occurs to anybody — not even to him who is convinced of this necessity — to exonerate himself on that account, and cast the blame on the motives; for he knows well enough that, objectively considered, any given circumstance, and its causes, perfectly admitted quite a different, indeed, a directly opposite course of action; nay, that such a course would actually have taken place, if only he had been a different person.
