The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
Claude Bernard

First causes are outside the realm of science.
Claude Bernard
Image
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
Image
Those who do not know the torment of the unknown cannot have the joy of discovery.
Claude Bernard
Image
Science increases our power in proportion as it lowers our pride.
Claude Bernard

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

The terrain is everything the germ is nothing.
