Atheism and morality - Conservapedia
Presumably the difference is (if we want to chalk it up to morality) that the good husband finds his wife's happiness a reward and her displeasure a punishment. This is the very definition of love. The other is more or less indifferent to her happiness. And if he finds her displeasure a reward, he's an abuser. So even if we assume a substantial agreement between Christians and atheists on what is right among people and take that as given, the question of morality in action isn't, "are you doing it for a reward"; it's, "what reward are you doing it for?"
Where do atheists get their morality? - Kids Without God
Mainstream Christianity, no doubt, somewhat schizophrenically alternates between reward morality and categorical imperative "because God said so" morality. But as C.S. Lewis noted in , "If there lurks in most modern minds the notion that to desire our own good and earnestly to hope for the enjoyment of it is a bad thing, I submit that this notion has crept in from Kant and the Stoics and is no part of the Christian faith." To use the ideal of "right for right's sake" as a gotcha, contrasted with a reward motivation, doesn't really say anything except that atheists must be rather aimless. If their goal is – not to redefine reward, but to be unmotivated by reward at all – then there can be no purposeful action at all.
