A doctor must work eighteen hours a day and seven days a week. If you cannot console yourself to this, get out of the profession.

A good teacher must know the rules a good pupil, the exceptions.

Facts are not science - as the dictionary is not literature.

Don't confuse hypothesis and theory. The former is a possible explanation the latter, the correct one. The establishment of theory is the very purpose of science.

Whenever ideas fail, men invent words.

In the sick room, ten cents' worth of human understanding equals ten dollars' worth of medical science.
