In passing, it might be pertinent to remark that the “good” implied by Class B is always _life-enhancing_, were it not for the fact that this obtrudes a standard not warranted by all users of this term. For the snap judgment (or even the pondered conclusion) of an exceedingly great number of people makes money the chief dependable “good,” that of others puts friends and companions in this category, while with fewer still knowledge is so regarded. Some of these things do not always turn out to be life-enhancing,—time, place, circumstance, and the ductless glands alter the assumed value of any such hypothesis. Hence “good” has been here defined simply in terms of what the organism is doing, and not in terms of any spurious teleological principle. Empirical science has no books to balance. He who watches a little closely will see that as far as conduct reveals it (which is, indeed, very far), all sorts of things that are not particularly life-enhancing are chosen hourly as the “highest goods” in the sense of being greedily and furiously pursued. Sexual excitement, drug-taking, gourmandizing, idling, and the latest styles in clothing vie with any and all of these soberer values for first place in the attention of numberless people. And while many a man may choose for himself, yet none can choose for all. Class B includes skilful and kind persons as objects to which the term “good” is customarily applied. No new difficulties confront our attempt to pronounce the physiological implications of our concept as thus employed, even if we are obliged to alter to some slight extent our previous point of view. The skilful man is called “good” simply because he does or can mobilize his energy to produce something which is regarded as useful, fit, or serviceable. Likewise, the skilful or kind person is one who may be counted on to assist in maintaining, restoring, or increasing any state of things that is regarded as desirable. And we who employ the concept “good” to praise or encourage such a man insinuate that the same mobilization of energy is going on within us. Indeed, as could be readily shown, all perceptions of persons involve an imitative or empathic response. That is why skill and virtuosity of all sorts are agreeable to behold. They furnish numerous outlets for subconscious action-tendencies.
