Belief cannot be reckoned with in terms of science, for science and faith are mutually exclusive.

Life itself is but the expression of a sum of phenomena, each of which follows the ordinary physical and chemical laws.

No doubt science cannot admit of compromises, and can only bring out the complete truth. Hence there must be controversy, and the strife may be, and sometimes must be, sharp. But must it even then be personal? Does it help science to attack the man as well as the statement? On the contrary, has not science the noble privilege of carrying on its controversies without personal quarrels?

If popular medicine gave the people wisdom as well as knowledge, it would be the best protection for scientific and well-trained physicians.

The task of science, therefore, is not to attack the objects of faith, but to establish the limits beyond which knowledge cannot go and found a unified self-consciousness within these limits.

The task of science is to stake out the limits of the knowable, and to center consciousness within them.

The body is a cell state in which every cell is a citizen. Disease is merely the conflict of the citizens of the state brought about by the action of external forces.
