Belief has no place as far as science reaches, and may be first permitted to take root where science stops.

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 physicians are the natural attorneys of the poor, and the social problems should largely be solved by them.

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

There can be no scientific dispute with respect to faith, for science and faith exclude one another.

Imprisoned quacks are always replaced by new ones.

Only those who regard healing as the ultimate goal of their efforts can, therefore, be designated as physicians.
