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.

Cellular pathology is not an end if one cannot see any alteration in the cell. Chemistry brings the clarification of living processes nearer than does anatomy. Each anatomical change must have been preceded by a chemical one.

It is the curse of humanity that it learns to tolerate even the most horrible situations by habituation, that it forgets the most shameful happenings in the daily shame of events, and that it can hardly understand when individuals aim to destroy this infamy.

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.

It is the curse of humanity that it learns to tolerate even the most horrible situations by habituation.

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

Brevity in writing is the best insurance for its perusal.
