Science does not permit exceptions. View quote
Claude Bernard
Man can learn nothing except by going from the known to the unknown. View quote
Claude Bernard
When we meet a fact which contradicts a prevailing theory, we must accept the fact and abandon the theory, even when the theory is supported by great names and generally accepted. View quote
Claude Bernard
All the vital mechanisms, varied as they are, have only one object, that of preserving constant the conditions of life in the internal environment. View quote
Claude Bernard
Science increases our power in proportion as it lowers our pride. View quote
Claude Bernard
The science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen. View quote
Claude Bernard
We must never make experiments to confirm our ideas, but simply to control them. View quote
Claude Bernard
The mental never influences the physical. It is always the physical that modifies the mental, and when we think that the mind is diseased, it is always an illusion. View quote
Claude Bernard
The stability of the internal medium is a primary condition for the freedom and independence of certain living bodies in relation to the environment surrounding them. (Claude Bernard)
Science admits no exceptions; otherwise there would be no determinism in science, or rather, there would be no science. View quote
Claude Bernard
Indeed, proof that a given condition always precedes or accompanies a phenomenon does not warrant concluding with certainty that a given condition is the immediate cause of that phenomenon. It must still be established that when this condition is removed, the phenomen will no longer appear. View quote
Claude Bernard
True science teaches us to doubt and to abstain from ignorance. View quote
Claude Bernard
It is what we know already that often prevents us from learning. View quote
Claude Bernard
The experimenter who does not know what he is looking for will not understand what he finds. View quote

Put off your imagination, as you put off your overcoat, when you enter the laboratory. Put it on again, as you put on your overcoat, when you leave. View quote

Science rejects the indeterminate. View quote
Claude Bernard
Mediocre men often have the most acquired knowledge. View quote
Claude Bernard
If I had to define life in a word, it would be: Life is creation. View quote
Claude Bernard
A modern poet has characterized the personality of art and the impersonality of science as follows: Art is I: Science is We. (Claude Bernard)
Theories are only verified hypotheses, verified by more or less numerous facts. Those verified by the most facts are the best, but even then they are never final, never to be absolutely believed. View quote
Claude Bernard
Ardent desire for knowledge, in fact, is the one motive attracting and supporting investigators in their efforts; and just this knowledge, really grasped and yet always flying before them, becomes at once their sole torment and their sole happiness.... A man of science rises ever, in seeking truth; and if he never finds it in its wholeness, he discovers nevertheless very significant fragments; and these fragments of universal truth are precisely what constitutes science. View quote
Claude Bernard
They make poor observations, because they choose among the results of their experiments only what suits their object, neglecting whatever is unrelated to it and carefully setting aside everything which might tend toward the idea they wish to combat. View quote
Claude Bernard
A fact in itself is nothing. It is valuable only for the idea attached to it, or for the proof which it furnishes. View quote
