Self-regarding acts are frequently classified as non-moral; even more frequently, they are assumed to have less moral weight than parallel other-regarding acts. I argue briefly against the first claim, and at greater length against the second. Our intuitions about the lesser moral weight of self-regarding acts arise from imperfectly recognized, and morally relevant, differences between acts which are ordinarily described in misleadingly parallel phrases. ‘Love of self,’ for instance, and ‘love of another’ are not symmetrical attitudes, in spite of the symmetrical grammar. More obviously, one cannot steal from, lie to, nor force oneself in the same way one can do these things to others. I conclude, therefore, that difference in moral weight never stems merely from a difference in the person concerned (myself or another), but rather from differences between the actions themselves; furthermore, that whatever it is wrong to do to a willing other, it is wrong to do to oneself.
