In his paper, Moral Motivation and Human Nature: Psychological Egoism, Feinberg argues against psychological egoism hedonism by showing that it is paradoxical. Furthermore he shows that this means that arguments for this position are also false. This paper looks to reconstruct this argument, and show the implications of it. Feinberg is arguing against psychological egoism hedonism, which states that humans only act to obtain one’s own pleasure, and hence happiness. Psychological egoism hedonism can be argued for since teaching morality requires incentivising good behaviour with pleasures, and disincentives bad behaviour with pain. Hence, this shows that people act morally as a means to gain pleasure, and thus presupposes Hedonism. Feinberg
