A desire to take medicine is, perhaps, the great feature which distinguishes man from other animals.
— Sir William Osler
'Recent Advances in Medicine', Science (1891), 17, 170.

A library … is a great catalyser, accelerating the nutrition and rate of progress in a profession.
— Sir William Osler
Address for the Dedication of the New Building of the Boston Medical Library (12 Jan 1901). Printed as 'Books and Men', The Boston Medical and Surgical Journal (17 Jan 1901), 144, No. 3, 60.

An old writer says that there are four sorts of readers: “Sponges which attract all without distinguishing; Howre-glasses which receive and powre out as fast; Bagges which only retain the dregges of the spices and let the wine escape, and Sives which retaine the best onelv.” A man wastes a great many years before he reaches the ‘sive’ stage.

At the outset do not be worried about this big question—Truth. It is a very simple matter if each one of you starts with the desire to get as much as possible. 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. In this unsatisfied quest the attitude of mind, the desire, the thirst—a thirst that from the soul must arise!—the fervent longing, are the be-all and the end-all.
— Sir William Osler

Even in populous districts, the practice of medicine is a lonely road which winds up-hill all the way and a man may easily go astray and never reach the Delectable Mountains unless he early finds those shepherd guides of whom Bunyan tells, Knowledge, Experience, Watchful, and Sincere.
— Sir William Osler
In Aequanimitas (1906), 299.
Science quotes on:  |  Medicine (221)  |  Physician (195)

Fed on the dry husks of facts, the human heart has a hidden want which science cannot supply.

In departing from any settled opinion or belief, the variation, the change, the break with custom may come gradually; and the way is usually prepared; but the final break is made, as a rule, by some one individual, … who sees with his own eyes, and with an instinct or genius for truth, escapes from the routine in which his fellows live. But he often pays dearly for his boldness.
— Sir William Osler
In The Harveian Oration, delivered before the Royal College of Physicians of London (18 Oct 1906). Printed in 'The Growth of Truth, as Illustrated in the Discovery of the Circulation of Blood', The Lancet (27 Oct 1906), Vol. 2, Pt. 2, 1114.

Like other departments of philosophy, medicine began with an age of wonder. The accidents of disease and the features of death aroused surprise and stimulated interest, and a beginning was made when man first asked in astonishment, Why should these things be?
— Sir William Osler
In 'The Evolution of Internal Medicine', Modern Medicine: Its Theory and Practice, (1907), Vol. 1, xvi.

My second fixed idea is the uselessness of men above sixty years of age, and the incalculable benefit it would be in commercial, political, and in professional life, if as a matter of course, men stopped work at this age.
— Sir William Osler
In farewell address, Johns Hopkins University, 'The Fixed Period', as quoted in Harvey Cushing, The Life of Sir William Osier (1925), vol. 1, 666. He was reflecting on his own intention to retire (now age 55) because he felt a teacher should have a fixed period of service. The title of his address was from an Anthony Trollope novel The Fixed Period which discussed the retiring of college teachers at age 60.

Now of the difficulties bound up with the public in which we doctors work, I hesitate to speak in a mixed audience. Common sense in matters medical is rare, and is usually in inverse ratio to the degree of education.
— Sir William Osler

Search the scriptures of human achievement and you cannot find any to equal in beneficence the introduction of Anæsthesia, Sanitation, with ail that it includes, and Asepsis—a short half century’s contribution towards the practical solution of the problems of human suffering, regarded as eternal and insoluble.
— Sir William Osler

Seeing and thinking have done much for human progress; in the sphere of mind and morals everything, and could the world have been saved by armchair philosophy, the Greeks would have done it; but only a novum organon could do this, the powerful possibilities of which were only revealed when man began to search our the secrets of nature by way of experiment, to use the words of Harvey.
— Sir William Osler

Take the sum of human achievement in action, in science, in art, in literature—subtract the work of the men above forty, and while we should miss great treasures, even priceless treasures, we would practically be where we are today. … The effective, moving, vitalizing work of the world is done between the ages of twenty-five and forty.
— Sir William Osler

That man can interrogate as well as observe nature was a lesson slowly learned in his evolution. Of the two methods by which he can do this, the mathematical and the experimental, both have been equally fruitful—by the one he has gauged the starry heights and harnessed the cosmic forces to his will; by the other he has solved many of the problems of life and lightened many of the burdens of humanity.
— Sir William Osler
In 'The Evolution of the Idea of Experiment in Medicine', in C.G. Roland, Sir William Osler, 1849-1919: A Selection for Medical Students (1982), 103. As cited in William Osler and Mark E. Silverman (ed.), The Quotable Osler (2002), 249

The extraordinary development of modern science may be her undoing. Specialism, now a necessity, has fragmented the specialities themselves in a way that makes the outlook hazardous. The workers lose all sense of proportion in a maze of minutiae.

The greater the ignorance the greater the dogmatism.
— Sir William Osler
In Montréal Médical Journal (1902). Collected in Aequanimitas, with Other Addresses to Medical Students, Nurses and Practitioners of Medicine (1904), 279. Osler was referring to the ignorant dogmatism in literature from pharmaceutical houses and the hucksterism of some of their representatives.

There is no more potent antidote to the corroding influence of mammon than the presence in the community of a body of men devoted to science, living for investigation and caring nothing for the lust of the eyes and the pride of life.

To each of us life is an experiment in Nature’s laboratory, and she tests and tries us in a thousand ways, using us and improving us if we serve her turn, ruthlessly dispensing with us if we do not.

To study the phenomenon of disease without books is to sail uncharted sea, while to study books without patients is not to go to sea at all.
— Sir William Osler

We are all dietetic sinners; only a small percent of what we eat nourishes us, the balance goes to waste and loss of energy .
— Sir William Osler

Who runs may read the scroll which reason has placed as a warning over the human menageries: “chained, not tamed.” And yet who can doubt that the leaven of science, working in the individual, leavens in some slight degree the whole social fabric. Reason is at least free, or nearly so; the shackles of dogma have been removed, and faith herself, freed from a morganatic alliance, finds in the release great gain.
— Sir William Osler
Address to the Wistar Institute of Anatomy and Biology of the University of Pennsylvania (1894). Collected in 'The Leaven of Science', Aequanimitas (1904), 100. A “morganatic” alliance is one between persons of unequal rank, the noble and the common.

Quotes by others about Sir William Osler (1)

That ability to impart knowledge … what does it consist of? … a deep belief in the interest and importance of the thing taught, a concern about it amounting to a sort of passion. A man who knows a subject thoroughly, a man so soaked in it that he eats it, sleeps it and dreams it—this man can always teach it with success, no matter how little he knows of technical pedagogy. That is because there is enthusiasm in him, and because enthusiasm is almost as contagious as fear or the barber’s itch. An enthusiast is willing to go to any trouble to impart the glad news bubbling within him. He thinks that it is important and valuable for to know; given the slightest glow of interest in a pupil to start with, he will fan that glow to a flame. No hollow formalism cripples him and slows him down. He drags his best pupils along as fast as they can go, and he is so full of the thing that he never tires of expounding its elements to the dullest.
This passion, so unordered and yet so potent, explains the capacity for teaching that one frequently observes in scientific men of high attainments in their specialties—for example, Huxley, Ostwald, Karl Ludwig, Virchow, Billroth, Jowett, William G. Sumner, Halsted and Osler—men who knew nothing whatever about the so-called science of pedagogy, and would have derided its alleged principles if they had heard them stated.
In Prejudices: third series (1922), 241-2.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
