The same argument is put in a more guarded, and, I think, unexceptionable form by Hutcheson. It is perhaps more remarkable that Hume, too, shares Butler's view which he expresses almost in the language of the famous sermons. ``There are'', he says, ``bodily wants or appetites, acknowledged by every one, which necessarily precede all sensual enjoyment, and carry us directly to seek possession of the object. Thus hunger and thirst have eating and drinking for their end: and from the gratification of these primary appetites arises a pleasure, which may become the object of another species of inclination that is secondary and interested.'' Hence Hume finds that ``the hypothesis which allows of a disinterested benevolence, distinct from self-love'', is ``conformable to the analogy of nature.'' See Enquiry concerning the Principles of Morals (Appendix II.).
