Note note 37 — ANALYSIS OF THE PHENOMENA OF THE HUMAN MIND James Mill

37 The principal doctrine of this chapter is, that Desire, and Aversion, are nothing but the idea of a pleasurable sensation, and the Idea of a painful sensation: which doctrine is then qualified by saying, that a desire is the idea of a pleasure associated with the future, an aversion the idea of a pain associated with the future.

But according to the whole spirit of the author’s speculations, and to his express affirmation in the beginning of the next chapter, the idea of any sensation associated with the future, constitutes the Expectation of it: and if so, it rested with him to prove that the expectation of a pleasure, or of a pain, is the same thing with the desire, or aversion. This is certainly not conformable to common observation. For, on the one hand, it is commonly understood that there may be desire or aversion without expectation; and on the other, expectation of a pleasure without any actual feeling of desire: one may expect, and even look forward with satisfaction to, the pleasure of a meal, although one is not, but only expects to be, hungry. So perfectly is it assumed that expectation, and desire or aversion, are not necessarily combined, that the case in which they are combined is signified by a special pair of names. Desire combined with expectation, is called by the name of Hope; Aversion combined with expectation, is known by the name of Fear.

I believe the fact to be that desire is not Expectation, but is more than the idea of the pleasure desired, being, in truth, the initiatory stage of Will. In what we call Desire there is, I think, always included a positive stimulation to action; either to the definite course of action which would lead to our obtaining the pleasure, or to a general restlessness and vague seeking after it. The stimulation may fall short of actually producing action: even when it prompts to a definite act, it may be repressed by a stronger motive, or by knowledge that the pleasure is not within present reach, nor can be brought nearer to us by any present action of our own. Still, there is, I think, always, the sense of a tendency to action, in the direction of pursuit of the pleasure, though the tendency may be overpowered by an external or an internal restraint. So also, in aversion, there is always a tendency to action of the kind which repels or avoids the painful sensation. But of these things more fully under the head of Will.—Ed.
