"No human being is constituted to know the truth, the whole truth, and nothing but the truth; and even the best of men must be content with fragments, with partial glimpses, never the full fruition."

"Shakespeare gets to the root of the alcohol question in his well-known statement—'Good wine is a good, familiar creature if it be well used.'"

"The best preparation for tomorrow is to do today's work superbly well."

"In the history of medicine, there are few instances in which a disease has been more accurately, more graphically or more briefly described."

"There are three classes of human beings: men, women and women physicians."

"Far too large a section of the treatment of disease is to-day controlled by the big manufacturing pharmacists, who have enslaved us in a plausible pseudo-science."

"One special advantage of the skeptical attitude of mind is that a man is never vexed to find that after all he has been in the wrong."

"In a true and perfect form, imperturbability is indissolubly associated with wide experience and an intimate knowledge of the varied aspects of disease. With such advantages he is so equipped that no eventuality can disturb the mental equilibrium of the physician; the possibilities are always manifest, and the course of action clear. From its very nature this precious quality is liable to be misinterpreted, and the general accusation of hardness, so often brought against the profession, has here its foundation. Now a certain measure of insensibility is not only an advantage, but a positive necessity in the exercise of a calm judgment, and in carrying out delicate operations. Keen sensibility is doubtless a virtue of high order, when it does not interfere with steadiness of hand or coolness of nerve; but for the practitioner in his working-day world, a callousness which thinks only of the good to be effected, and goes ahead regardless of smaller considerations, is the preferable quality. Cultivate, then, gentlemen, such a judicious measure of obtuseness as will enable you to meet the exigencies of practice with firmness and courage, without, at the same time, hardening "the human heart by which we live.""

"The re-interpretation and eventually eradication of the concept of right and wrong which has been the basis of child training, the substitution of intelligent and rational thinking for faith in the certainties of the old people, these are the belated objectives of practically all effective psychotherapy."

"Children must be free to think in all directions irrespective of the peculiar ideas of parents who often seal their children's minds with preconceived prejudices and false concepts of past generations. Unless we are very careful, very careful indeed, and very conscientious, there is still great danger that our children may turn out to be the same kind of people we are."

"The world was sick, and the ills from which it was suffering were mainly due to the perversion of man, his inability to live at peace with himself. The microbe was no longer the main enemy; science was sufficiently advanced to be able to cope with it admirably. If it were not for such barriers as superstition, ignorance, religious intolerance, misery and poverty."
