The doubter is a true man of science; he doubts only himself and his interpretations, but he believes in science.
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.
Claude Bernard
The experimenter who does not know what he is looking for will not understand what he finds.
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
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.
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.
Claude Bernard
