More quotes by 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
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
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

The terrain is everything the germ is nothing.

It is what we know already that often prevents us from learning.

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.

Image
Science does not permit exceptions.
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
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
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.
Claude Bernard
Image
The science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen.
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 better educated we are and the more acquired information we have, the better prepared shall we find our minds for making great and fruitful discoveries.
Claude Bernard
Image
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
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
In the philosophic sense, observation shows and experiment teaches.
Claude Bernard
Image
We must alter theory to adapt it to nature, but not nature to adapt it to theory.
Claude Bernard
Image
The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
Claude Bernard
Image
True science teaches us to doubt and, in ignorance, to refrain.
