Quote

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.

First causes are outside the realm of 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
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
Image
The eloquence of a scientist is clarity scientific truth is always more luminous when its beauty is unadorned than when it is tricked out in the embellishments with which our imagination would seek to clothe it.
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 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
True science teaches us to doubt and, in ignorance, to refrain.
Claude Bernard
Image
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
Claude Bernard
Image
Science does not permit exceptions.
Claude Bernard
Image
Il ne fallait jamais faire des expériences pour confirmer ses idées, mais simplement pour les contrôler. We must never make experiments to confirm our ideas, but simply to control them.
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 experimenter who does not know what he is looking for will not understand what he finds.
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.
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
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.

The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
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
The science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen.

In the philosophic sense, observation shows and experiment teaches.
