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 BERNARDWhen 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.

The joy of discovery is certainly the liveliest that the mind of man can ever feel.
CLAUDE BERNARD -
True science teaches us to doubt and, in ignorance, to refrain.
CLAUDE BERNARD -
Feeling alone guides the mind.
CLAUDE BERNARD -
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 -
The terrain is everything; the germ is nothing.
CLAUDE BERNARD -
We must alter theory to adapt it to nature, but not nature to adapt it to theory.
CLAUDE BERNARD -
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 -
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 -
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 -
Science admits no exceptions; otherwise there would be no determinism in science, or rather, there would be no science.
CLAUDE BERNARD -
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 -
Art is ‘I’; science is ‘we’.
CLAUDE BERNARD -
When entering on new ground we must not be afraid to express even risky ideas so as to stimulate research in all directions. As Priestley put it, we must not remain inactive through false modesty based on fear of being mistaken.
CLAUDE BERNARD -
Particular facts are never scientific; only generalization can establish science.
CLAUDE BERNARD -
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. ‘

We achieve more than we know. We know more than we understand. We understand more than we can explain.
CLAUDE BERNARD -
The investigator should have a robust faith – and yet not believe.
