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

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.

Medicine is a social science, and politics is nothing more than medicine on a grand scale.

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

If we would serve science, we must extend her limits, not only as far as our own knowledge is concerned, but in the estimation of others.

Medical statistics will be our standard of measurement: we will weigh life for life and see where the dead lie thicker, among the workers or among the privileged.

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