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

We must never make experiments to confirm our ideas, but simply to control them.

The terrain is everything; the germ is nothing.

CLAUDE BERNARD

Believe Enough Firm Man Seek Theory Truth
Hatred is the most clear- sighted, next to genius.

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

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
The better educated we are and the more acquired information we have, the better prepared shall we find our minds for making great and fruitful discoveries.
