"The very problem of mind and body suggests division; I do not know of anything so disastrously affected by the habit of division as this particular theme. In its discussion are reflected the splitting off from each other of religion, morals and science; the divorce of philosophy from science and of both from the arts of conduct. The evils which we suffer in education, in religion, in the materialism of business and the aloofness of "intellectuals" from life, in the whole separation of knowledge and practice -- all testify to the necessity of seeing mind-body as an integral whole."
