However, with the lowest psychisms, we may perhaps suppose it unlikely that representation does ever become definite enough for desire, except when in direct sensing of a thing, as, for example, in a touch perception. The psychism is impelled to touch activity by its subjective pains and simple, undifferentiated lack pains. It does not desire a food through the representation of it brought up by hunger, for such representation of things in their potentiality is probably not originally stimulated directly by subjective feelings, though with man, for instance, we know that hunger and other simple feelings will provoke representations of foods, which foods will be desired; and particularly in famine the most lively representations of feasts occur, and thus there is a strengthening and defining of desire. Thus in famine there comes a greater and greater urgency to action as its necessity becomes greater. The vivid representations of foods become through desire—though there may be no sense connection with food—a mighty force for self-preservative action. Yet primitively desire probably awoke only after some sensing was accomplished, not the mere subjective pain, but the touch perception awoke the representation, for it would seem the original _status_ that representation occurs at first only with correlated presentation. Thus it is that the simplest psychisms are driven by their pains to achieve a touch or some sensing of a thing before they interpret it as food, and so desire it; that is, things must have a food meaning attached to them through actual sense appreciation of them as such, before they can be directly instanced in pure representation as foods. Hunger leads us immediately to think of food, but this ability to directly represent food is based upon having thoroughly learned certain things as food by repeated direct experiences. A savage who has never seen or known of bonbons is presented with a box of them, and he may receive them with indifference, but a bonbon is placed in his mouth, whereupon he says, “it tasted so good, I want another.” Such is the genesis of desire when pleasure quality is attached to thing, is learned by experience. The visual and tactual experience is actively conjoined with pleasure experience, so that seeing another bonbon, he represents its pleasurability and so desires it.
