But while I accept specialization in the practice, I reject it utterly in the theory of science.

Claude Bernard

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

Beautiful Imagination Ourselves Science Truth
In science, the best precept is to alter and exchange our ideas as fast as science moves ahead.
CLAUDE BERNARD

Ahead exchange Fast Ideas Move Science
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

Built Death Fact Material Observation Science
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

Condition Force Law Manifestation State
Man can learn nothing unless he proceeds from the known to the unknown.

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

Character Clear Creation Expression Life Science
We must remain, in a word, in an intellectual disposition which seems paradoxical, but which, in my opinion, represents the true mind of the investigator. We must have a robust faith and yet not believe.
CLAUDE BERNARD

Believe Faith Intellectual Opinion Word
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.

We must never make experiments to confirm our ideas, but simply to control them.
CLAUDE BERNARD

Confirm Control Experiment Simplicity
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

Kitchen Life Light Reach Science
True science teaches us to doubt and, in ignorance, to refrain.
CLAUDE BERNARD

Doubt Ignorance Science Teaching True
First causes are outside the realm of science.
CLAUDE BERNARD

A discovery is generally an unforeseen relation not included in theory.
CLAUDE BERNARD

Discover General Theory
In the philosophic sense, observation shows and experiment teaches.
CLAUDE BERNARD

Experiment Observation Philosophy Teaching
Experiment is fundamentally only induced observation.
CLAUDE BERNARD

Experiment Fundamental Observation
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.
