The idea that excessive physical exercise is a sound means of promoting
health is erroneous. Man is not constructed to be a running or a leaping
animal like a deer or a cat, and to raise the physical above the mental
culture were to return to the shortness and misery of savage life.
Physical training, while it should be moderately encouraged, should be
refined and made secondary to mental training. Every rash and violent
feat of competitive prowess should be discountenanced.
