The idea persists that there is something materialistic about natural science and that morals are degraded by having anything seriously to do with material things. If a sect should arise proclaiming that men ought to purify their lungs completely before they ever drew a breath it ought to win many adherents from professed moralists. For the neglect of sciences that deal specifically with facts of the natural and social environment leads to a sidetracking of moral forces into an unreal privacy of an unreal self. It is impossible to say how much of the remediable suffering of the world is due to the fact that physical science is looked upon as merely physical. It is impossible to say how much of the unnecessary slavery of the world is due to the conception that moral issues can be settled within conscience or human sentiment apart from consistent study of facts and application of specific knowledge in industry, law and politics. Outside of manufacturing and transportation, science gets its chance in war. These facts perpetuate war and the hardest, most brutal side of modern industry. Each sign of disregard for the moral potentialities of physical science drafts the conscience of mankind away from concern with the interactions of man and nature which must be mastered if freedom is to be a reality. It diverts intelligence to anxious preoccupation with the unrealities of a purely inner life, or strengthens reliance upon outbursts of sentimental affection. The masses swarm to the occult for assistance. The cultivated smile contemptuously. They might smile, as the saying goes, out of the other side of their mouths if they realized how recourse to the occult exhibits the practical logic of their own beliefs. For both rest upon a separation of moral ideas and feelings from knowable facts of life, man and the world.
It is not pretended that a moral theory based upon realities of human nature and a study of the specific connections of these realities with those of physical science would do away with moral struggle and defeat. It would not make the moral life as simple a matter as wending one’s way along a well-lighted boulevard. All action is an invasion of the future, of the unknown. Conflict and uncertainty are ultimate traits. But morals based upon concern with facts and deriving guidance from knowledge of them would at least locate the points of effective endeavor and would focus available resources upon them. It would put an end to the impossible attempt to live in two unrelated worlds. It would destroy fixed distinction between the human and the physical, as well as that between the moral and the industrial and political. A morals based on study of human nature instead of upon disregard for it would find the facts of man continuous with those of the rest of nature and would thereby ally ethics with physics and biology. It would find the nature and activities of one person coterminous with those of other human beings, and therefore link ethics with the study of history, sociology, law and economics.
Such a morals would not automatically solve moral problems, nor resolve perplexities. But it would enable us to state problems in such forms that action could be courageously and intelligently directed to their solution. It would not assure us against failure, but it would render failure a source of instruction. It would not protect us against the future emergence of equally serious moral difficulties, but it would enable us to approach the always recurring troubles with a fund of growing knowledge which would add significant values to our conduct even when we overtly failed—as we should continue to do. Until the integrity of morals with human nature and of both with the environment is recognized, we shall be deprived of the aid of past experience to cope with the most acute and deep problems of life. Accurate and extensive knowledge will continue to operate only in dealing with purely technical problems. The intelligent acknowledgment of the continuity of nature, man and society will alone secure a growth of morals which will be serious without being fanatical, aspiring without sentimentality, adapted to reality without conventionality, sensible without taking the form of calculation of profits, idealistic without being romantic.

Habits as Social Functions
Habits may be profitably compared to physiological functions, like breathing, digesting. The latter are, to be sure, involuntary, while habits are acquired. But important as is this difference for many purposes it should not conceal the fact that habits are like functions in many respects, and especially in requiring the cooperation of organism and environment. Breathing is an affair of the air as truly as of the lungs; digesting an affair of food as truly as of tissues of stomach. Seeing involves light just as certainly as it does the eye and optic nerve. Walking implicates the ground as well as the legs; speech demands physical air and human companionship and audience as well as vocal organs. We may shift from the biological to the mathematical use of the word function, and say that natural operations like breathing and digesting, acquired ones
