In science, the best precept is to alter and exchange our ideas as fast as science moves ahead.

Claude Bernard

The true worth of an experimenter consists in his pursuing not only what he seeks in his experiment, but also what he did not seek.
CLAUDE BERNARD

Experiment Himself Seek True Worth
Man can learn nothing unless he proceeds from the known to the unknown.
CLAUDE BERNARD

Learning Man Unknown
With the aid of these active experimental sciences man becomes an inventor of phenomena, a real foreman of creation; and under this head we cannot set limits to the power that he may gain over nature through future progress of the experimental sciences.
CLAUDE BERNARD

Active Creation Experiment Head Limitation Nature Progress Science
We must never make experiments to confirm our ideas, but simply to control them.
CLAUDE BERNARD

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.

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

Determination Fact Goal Reason Reduce Science
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
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
