Claude Bernard

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

Confirm Control Experiment Simplicity
The investigator should have a robust faith – and yet not believe.
CLAUDE BERNARD

Believe Faith Investigate
When entering on new ground we must not be afraid to express even risky ideas so as to stimulate research in all directions. As Priestley put it, we must not remain inactive through false modesty based on fear of being mistaken.
CLAUDE BERNARD

Afraid Direction Fear Ground Ideas Mistake Modesty Risk
But while I accept specialization in the practice, I reject it utterly in the theory of science.
CLAUDE BERNARD

Acceptance Myself Practice Science Theory

Mediocre men often have the most acquired knowledge.

Science rejects the indeterminate.
CLAUDE BERNARD

A fact in itself is nothing. It is valuable only for the idea attached to it, or for the proof which it furnishes.
CLAUDE BERNARD

Attachment Evidence Fact Ideas Value
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.
