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

If I had to define life in a single phrase, I should clearly express my thought of throwing into relief one characteristic which, in my opinion, sharply differentiates biological science. I should say: life is creation.
CLAUDE BERNARD

Character Clear Creation Expression Life Science
Those who do not know the torment of the unknown cannot have the joy of discovery.
CLAUDE BERNARD

Discover Hard Time Joy Struggle
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
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
CLAUDE BERNARD

Discover Feeling Live Mindset
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
Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.
CLAUDE BERNARD

Delicate Live Mechanism Organism Property Wonderful
We must never make experiments to confirm our ideas, but simply to control them.
CLAUDE BERNARD

Confirm Control Experiment Ideas Simplicity
A discovery is generally an unforeseen relation not included in theory.
CLAUDE BERNARD

Discover General Theory
Mediocre men often have the most acquired knowledge. It is in the darker. It is in the darker regions of science that great men are recognized; they are marked by ideas which light up phenomena hitherto obscure and carry science forward.
CLAUDE BERNARD

Average Darkness Greatness Knowledge Man Recognition Science
Priestley said that each discovery we make shows us many others that should be made.
CLAUDE BERNARD

Discover Science Show
All the vital mechanisms, varied as they are, have only one object, that of preserving constant the conditions of life in the internal environment.
CLAUDE BERNARD

Condition Environment Object Oneself Preserve
It is what we know already that often prevents us from learning.
CLAUDE BERNARD

Deep Knowledge Learning Ourselves Prevent
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
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
Everything is poisonous, nothing is poisonous, it is all a matter of dose.
CLAUDE BERNARD

Amount Poison Portion
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
