Suppose action A is morally wrong. Person S does not plan to do A because s/he sincerely believes that doing it is wrong. However, s/he is very tempted to do A, and so S constantly thinks about doing A but never actually does A. Is S morally culpable?
Aristotle comes very close to answering this by saying that the unrestrained person is morally culpable because he knows that A is wrong, but nevertheless does it. However, my example above never says that S actually does A; S wants to do A and desires to do A but never actually does A. Can thinking–but not doing–an immoral action still be morally wrong?
