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 side-tracking 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.
