Image
True science teaches us to doubt and, in ignorance, to refrain.
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
Science increases our power in proportion as it lowers our pride.
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
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
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
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
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
A discovery is generally an unforeseen relation not included in theory.

Image
Mediocre men often have the most acquired knowledge
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
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
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
Those who do not know the torment of the unknown cannot have the joy of discovery.
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
Obervation is a passive science, experimentation is an active science.
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
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

The terrain is everything the germ is nothing.
