Is there any sense in which a thing can be an ultimate rational end for one person and not for another? By ‘ultimate’ must be meant at least that the end is good-in-itself—good in our undefinable sense; and by ‘rational,’ at least, that it is truly good. That a thing should be an ultimate rational end means, then, that it is truly good in itself; and that it is truly good in itself means that it is a part of Universal Good. Can we assign any meaning to that qualification ‘for himself,’ which will make it cease to be a part of Universal Good? The thing is impossible: for the Egoist’s happiness must either be good in itself, and so a part of Universal Good, or else it cannot be good in itself at all: there is no escaping this dilemma. And if it is not good at all, what reason can he have for aiming at it? how can it be a rational end for him? That qualification ‘for himself’ has no meaning unless it implies ‘not for others’; and if it implies ‘not for others,’ then it cannot be a rational end for him, since it cannot be truly good in itself: the phrase ‘an ultimate rational end for himself’ is a contradiction in terms. By saying that a thing is an end for one particular person, or good for him, can only be meant one of four things. Either (1) it may be meant that the end in question is something which will belong exclusively to him; but in that case, if it is to be rational for him to aim at it, that he should exclusively possess it must be a part of Universal Good. Or (2) it may be meant that it is the only thing at which he ought to aim; but this can only be, because, by so doing, he will do the most he can towards realising Universal Good: and this, in our case, will only give Egoism as a doctrine of means. Or (3) it may be meant that the thing is what he desires or thinks good; and then, if he thinks wrongly, it is not a rational end at all, and, if he thinks rightly, it is a part of Universal Good. Or (4) it may be meant that it is peculiarly appropriate that a thing which will belong exclusively to him should also by him be approved or aimed at; but, in this case, both that it should belong to him and that he should aim at it must be parts of Universal Good: by saying that a certain relation between two things is fitting or appropriate, we can only mean that the existence of that relation is absolutely good
