This is a vague statement. But note in the first place that such a conception of the proper province of philosophy where it is released from vain metaphysics and idle epistemology is in line with the origin of philosophy sketched in the first hour. And in the second place, note how contemporary society, the world over, is in need of more general and fundamental enlightenment and guidance than it now possesses. I have tried to show that a radical change of the conception of knowledge from contemplative to active is the inevitable result of the way in which inquiry and invention are now conducted. But in claiming this, it must also be conceded, or rather asserted, that so far the change has influenced for the most part only the more technical side of human life. The sciences have created new industrial arts. Man's physical command of natural energies has been indefinitely multiplied. There is control of the sources of material wealth and prosperity. What would once have been miracles are now daily performed with steam and coal and electricity and air, and with the human body. But there are few persons optimistic enough to declare that any similar command of the forces which control man's social and moral welfare has been achieved.
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?
