A great discovery is a fact whose appearance in science gives rise to shining ideas, whose light dispels many obscurities and shows us new paths.

Claude Bernard

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
Science increases our power in proportion as it lowers our pride.
CLAUDE BERNARD

Lower Ourselves Power Pride Science
The experimenter who does not know what he is looking for will not understand what he finds.
CLAUDE BERNARD

Experiment Himself Philosophy Research Understand
Those who have an excessive faith in their theories or in their ideas are not only poorly disposed to make discoveries, but they also make very poor observations.
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
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
Priestley said that each discovery we make shows us many others that should be made.
CLAUDE BERNARD

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.
CLAUDE BERNARD

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
