The stability of the internal medium is a primary condition for the freedom and independence of certain living bodies in relation to the environment surrounding them.
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
We must alter theory to adapt it to nature, but not nature to adapt it to theory.
Claude Bernard
Image
It is what we know already that often prevents us from learning.
Claude Bernard

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

Claude Bernard
Image
Obervation is a passive science, experimentation is an active science.
Claude Bernard

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
True science teaches us to doubt and, in ignorance, to refrain.
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
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
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
In the philosophic sense, observation shows and experiment teaches.
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

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. '
