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
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
We achieve more than we know. We know more than we understand. We understand more than we can explain.
Claude Bernard
Image
The fact that knowledge endlessly recedes as the investigator is about to grasp it is what constitutes at the same time his torment and happiness.
Claude Bernard
Image
The terrain is everything the germ is nothing.
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.

First causes are outside the realm of science.

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

Hatred is the most clear- sighted, next to genius.

Science admits no exceptions otherwise there would be no determinism in science, or rather, there would be no science.

Obervation is a passive science, experimentation is an active science.
Claude Bernard
Image
In these researches I followed the principles of the experimental method that we have established, i.e., that, in presence of a well-noted, new fact which contradicts a theory, instead of keeping the theory and abandoning the fact, I should keep and study the fact, and I hastened to give up the theory.

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
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
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
Those who do not know the torment of the unknown cannot have the joy of discovery.
Claude Bernard
Image
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
Claude Bernard
Image
A discovery is generally an unforeseen relation not included in theory.
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.

Science increases our power in proportion as it lowers our pride.
