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

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

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

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
A man of science rises ever, in seeking truth; and if he never finds it in its wholeness, he discovers nevertheless very significant fragments; and these fragments of universal truth are precisely what constitutes science.
CLAUDE BERNARD

CLAUDE BERNARD

Priestley said that each discovery we make shows us many others that should be made.

We achieve more than we know. We know more than we understand. We understand more than we can explain.

The mental never influences the physical. It is always the physical that modifies the mental, and when we think that the mind is diseased, it is always an illusion.

The experimenter who does not know what he is looking for will not understand what he finds.

Obervation is a passive science, experimentation is an active science.

When we meet a fact which contradicts a prevailing theory, we must accept the fact and abandon the theory, even when the theory is supported by great names and generally accepted.
