The instincts of every animal appear to have for their quasi-purpose the presentation of the race of which that animal is a member, and this in one or other of two ways,

2nd, by causing him to reproduce his kind, and rear his offspring. This remark, even if it does not quite cover all the instincts, ought to afford a key to the classification of the instincts, and through them of purposes in general, and particularly of scientific purposes. Let us then draw up an orderly list of all the instincts of man, and from this form another of all scientific inquiries directed to the ascertainment of the best ways of giving these instincts free play and of satisfying the desire to which they give rise. This will be a natural
