As regards Class C, the concept “good” points to “that which fulfils expectation,” that is, the _normal_ or _typical_ thing. These words “normal” and “typical” (“implying the existence of characteristic qualities”) are related to the word “good” by means of the conditioned reflex. Our experience with all such things as motor-cars, for example, involves not only cognition, but eventually discrimination and comparison as well. Thereafter, when we hear of a _good_ motor-car, we think of such a one as we have been trained to regard as capable of a certain kind of performance. The same thing holds with respect to all other objects and persons concerning whom we have become discriminative. “Good,” thus employed, seems to imply that energy is being mobilized to perform selective activity, and also that the sense organs have become specially attuned to receive a specific stimulus. The “good” cat is not any old beast of the back alley, but a mouser with a certain number of catches to her credit. The “good” grocer (that is, supposedly _normal_) is one who gives full weight and makes prompt deliveries. Moreover, there is implicit in all such uses of this value predicate some reference to that dependability which was discussed in connection with Class B. Here, then, we may state that Class C implies _the mobilization of energy for the performance of such action as will maintain our physical or mental equilibrium_. And this, physiologically speaking, is ultimately a matter of the progressive coordination of reflexes and the maintenance of muscular tone.
