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

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

In teaching man, experimental science results in lessening his pride more and more by proving to him every day that primary causes, like the objective reality of things, will be hidden from him forever and that he can only know relations.
CLAUDE BERNARD

Experiment Forever Man Reality Relation Science Teaching
We must alter theory to adapt it to nature, but not nature to adapt it to 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.

Particular facts are never scientific; only generalization can establish 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.

Determination Fact Goal Reason Reduce Science
We achieve more than we know. We know more than we understand. We understand more than we can explain.

Art is ‘I’; science is ‘we’.

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