Hence the love of pleasure against which moralists issue so many warnings. Not that love of pleasures is in itself in any way demoralizing. Love of the pleasures of cheerfulness, of companionship is one of the steadying influences in conduct. But pleasure has often become identified with special thrills, excitations, ticklings of sense, stirrings of appetite for the express purpose of enjoying the immediate stimulation irrespective of results. Such pleasures are signs of dissipation, dissoluteness, in the literal sense. An activity which is deprived of regular stimulation and normal function is piqued into isolated activity, and the result is division, disassociation. A life of routine and of over-specialization in non-routine lines seek occasions in which to arouse by abnormal means a _feeling_ of satisfaction without any accompanying objective fulfilment. Hence, as moralists have pointed out, the insatiable character of such appetites. Activities are not really satisfied, that is fulfilled in objects. They continue to seek for gratification in more intensified stimulations. Orgies of pleasure-seeking, varying from saturnalia to mild sprees, result. It does not follow however that the sole alternative is satisfaction by means of objectively serviceable action, that is by action which effects useful changes in the environment. There is an optimistic theory of nature according to which wherever there is natural law there is also natural harmony. Since man as well as the world is included in the scope of natural law, it is inferred that there is natural harmony between human activities and surroundings, a harmony which is disturbed only when man indulges in "artificial" departures from nature. According to this view, all man has to do is to keep his occupations in balance with the energies of the environment and he will be both happy and efficient. Rest, recuperation, relief can be found in a proper alternation of forms of useful work. Do the things which surroundings indicate need doing, and success, content, restoration of powers will take care of themselves.
