William Osler

The physician must be a man of courage.

The student who is not prepared to take the whole world for his oyster is not prepared for the study of medicine.

The chief mental stock-in-trade of the successful physician is common sense.

Live not in the past, look not to the future, but do the thing that is before you, whether it is eating your breakfast, or kissing your wife, or tending to a dying man.

The way to learn medicine is to be in the hospital, not in the lecture-room.

It is astonishing with how little reading a doctor can practice medicine, but it is not astonishing how badly he may do it.

The student must be taught to see, to hear, to feel, to smell, and to reason, and to reason correctly.

The physician is the only person who can truly understand the patient's suffering.

The student of medicine should be a student for life.

The physician who knows only medicine, knows not even medicine.

The life of a physician is one of constant self-sacrifice.

The greatest teacher is the patient.

The practice of medicine is not a trade, but a profession, and a profession of the highest order.

The student must be taught to think for himself, to observe for himself, and to reason for himself.

The greatest asset of a physician is his common sense.

The physician who does not read is like a ship without a rudder.

The secret of success in medicine is to work hard, to observe carefully, and to think clearly.

The physician must be a man of integrity, a man of honor, and a man of compassion.

Live not in the past, but in the present. The past is gone, the future is not yet. The present is all we have.

He who studies medicine without books sails an uncharted sea, but he who studies medicine without patients does not go to sea at all.
