The joy of discovery is certainly the liveliest that the mind of man can ever feel.

Claude Bernard

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
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

Break Change Enough Ideas Instrument Intellectual Purpose
First causes are outside the realm of science.
CLAUDE BERNARD

Reason 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
True science teaches us to doubt and, in ignorance, to refrain.
CLAUDE BERNARD

Doubt Ignorance Science Teaching True
Particular facts are never scientific; only generalization can establish science.
CLAUDE BERNARD

Establishment Fact General Science
Art is ‘I’; science is ‘we’.
CLAUDE BERNARD

Art Science
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
Science does not permit exceptions.
CLAUDE BERNARD

Exception One Liner Science
Man can learn nothing unless he proceeds from the known to the unknown.
CLAUDE BERNARD

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

Discover General Theory
Men who believe too firmly in their theories, do not believe enough in the theories of others. So these despisers of their fellows make experiments only to destroy a theory, instead of to seek the truth.
CLAUDE BERNARD

Believe Enough Firm Man Seek Theory Truth
We must never make experiments to confirm our ideas, but simply to control them.
CLAUDE BERNARD

Confirm Control Experiment Simplicity
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
We must alter theory to adapt it to nature, but not nature to adapt it to theory.‎
CLAUDE BERNARD

Adapt Nature Theory
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

Imagination Leaving Science Yourself
