Where is the moral progress that corresponds to our economic accomplishments? The latter is the direct fruit of the revolution that has been wrought in physical science. But where is there a corresponding human science and art? Not only has the improvement in the method of knowing remained so far mainly limited to technical and economic matters, but this progress has brought with it serious new moral disturbances. I need only cite the late war, the problem of capital and labor, the relation of economic classes, the fact that while the new science has achieved wonders in medicine and surgery, it has also produced and spread occasions for diseases and weaknesses. These considerations indicate to us how undeveloped are our politics, how crude and primitive our education, how passive and inert our morals. The causes remain which brought philosophy into existence as an attempt to find an intelligent substitute for blind custom and blind impulse as guides to life and conduct. The attempt has not been successfully accomplished. Is there not reason for believing that the release of philosophy from its burden of sterile metaphysics and sterile epistemology instead of depriving philosophy of problems and subject-matter would open a way to questions of the most perplexing and the most significant sort? Let me specify one problem quite directly suggested by certain points in this lecture. It has been pointed out that the really fruitful application of the contemplative idea was not in science but in the esthetic field. It is difficult to imagine any high development of the fine arts except where there is curious and loving interest in forms and motions of the world quite irrespective of any use to which they may be put. And it is not too much to say that every people that has attained a high esthetic development has been a people in which the contemplative attitude has flourished--as the Greek, the Hindoo, the medieval Christian. On the other hand, the scientific attitude that has actually proved itself in scientific progress is, as has been pointed out, a practical attitude. It takes forms as disguises for hidden processes. Its interest in change is in what it leads to, what can be done with it, to what use it can be put. While it has brought nature under control, there is something hard and aggressive in its attitude toward nature unfavorable to the esthetic enjoyment of the world. Surely there is no more significant question before the world than this question of the possibility and method of reconciliation of the attitudes of practical science and contemplative esthetic appreciation. Without the former, man will be the sport and victim of natural forces which he cannot use or control. Without the latter, mankind might become a race of economic monsters, restlessly driving hard bargains with nature and with one another, bored with leisure or capable of putting it to use only in ostentatious display and extravagant dissipation.
