Science does not permit exceptions.
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
Effects vary with the conditions which bring them to pass, but laws do not vary. Physiological and pathological states are ruled by the same forces they differ only because of the special conditions under which the vital laws manifest themselves.
Claude Bernard
Image
Mediocre men often have the most acquired knowledge. It is in the darker. It is in the darker regions of science that great men are recognized they are marked by ideas which light up phenomena hitherto obscure and carry science forward.
Claude Bernard
Image
A contemporary poet has characterized this sense of the personality of art and of the impersonality of science in these words,-'Art is myself science is ourselves. '
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.

Priestley [said] that each discovery we make shows us many others that should be made.

Obervation is a passive science, experimentation is an active science.
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.

Image
In a word, I consider hospitals only as the entrance to scientific medicine they are the first field of observation which a physician enters but the true sanctuary of medical science is a laboratory only there can he seek explanations of life in the normal and pathological states by means of experimental analysis.

The joy of discovery is certainly the liveliest that the mind of man can ever feel.

Claude Bernard
Image
Our ideas are only intellectual instruments which we use to break into phenomena we must change them when they have served their purpose, as we change a blunt lancet that we have used long enough.
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
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
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
In teaching man, experimental science results in lessening his pride more and more by proving to him every day that primary causes, like the objective reality of things, will be hidden from him forever and that he can only know relations.
Claude Bernard
Image
Science rejects the indeterminate.

The terrain is everything the germ is nothing.

Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.
