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
Science increases our power in proportion as it lowers our pride.
Claude Bernard
Image
In a word, I consider hospitals only as the entrance to scientific medicine they are the first field of observation which a physician enters but the true sanctuary of medical science is a laboratory only there can he seek explanations of life in the normal and pathological states by means of experimental analysis.
Claude Bernard
Image
We must alter theory to adapt it to nature, but not nature to adapt it to theory.
Claude Bernard
Image
Science rejects the indeterminate.
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
Image
Hatred is the most clear- sighted, next to genius.
Claude Bernard
Image
In the philosophic sense, observation shows and experiment teaches.
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
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 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
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
Those who do not know the torment of the unknown cannot have the joy of discovery.
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.

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
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.
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
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
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.
