Image
Well-observed facts, though brought to light by passing theories, will never die they are the material on which alone the house of science will at last be built.
Claude Bernard
Image
Theories are like a stairway by climbing, science widens its horizon more and more, because theories embody and necessarily include proportionately more facts as they advance.
Claude Bernard
Image
Mediocre men often have the most acquired knowledge
Claude Bernard
Image
The goal of scientific physicians in their own science ... is to reduce the indeterminate. Statistics therefore apply only to cases in which the cause of the facts observed is still indeterminate.
Claude Bernard
Image
Men who believe too firmly in their theories, do not believe enough in the theories of others. So ... these despisers of their fellows ... make experiments only to destroy a theory, instead of to seek the truth.
Claude Bernard
Image
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.
Claude Bernard
Image
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.
Claude Bernard
Image
The eloquence of a scientist is clarity scientific truth is always more luminous when its beauty is unadorned than when it is tricked out in the embellishments with which our imagination would seek to clothe it.
Claude Bernard
Image
Progress is achieved by exchanging our theories for new ones which go further than the old, until we find one based on a larger number of facts. ... Theories are only 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.
Claude Bernard
Image
If I had to define life in a single phrase, I should clearly express my thought of throwing into relief one characteristic which, in my opinion, sharply differentiates biological science. I should say: life is creation.
Claude Bernard
Image
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.
Claude Bernard
Image
True science teaches us to doubt and, in ignorance, to refrain.
Claude Bernard
Image
A great discovery is a fact whose appearance in science gives rise to shining ideas, whose light dispels many obscurities and shows us new paths.
Claude Bernard
Image
Science admits no exceptions otherwise there would be no determinism in science, or rather, there would be no science.
Claude Bernard
Image
The terrain is everything the germ is nothing.
Claude Bernard
Image
We achieve more than we know. We know more than we understand. We understand more than we can explain.
Claude Bernard
Image
It is what we know already that often prevents us from learning.
Claude Bernard
Image
All the vital mechanisms, varied as they are, have only one object, that of preserving constant the conditions of life in the internal environment.
Claude Bernard
Image
Il ne fallait jamais faire des expériences pour confirmer ses idées, mais simplement pour les contrôler. We must never make experiments to confirm our ideas, but simply to control them.
Claude Bernard
Image
In the philosophic sense, observation shows and experiment teaches.
