Claude Bernard
Claude Bernardwas a French physiologist. Historian Ierome Bernard Cohen of Harvard University called Bernard "one of the greatest of all men of science". Among many other accomplishments, he was one of the first to suggest the use of blind experiments to ensure the objectivity of scientific observations.

We must alter theory to adapt it to nature, but not nature to adapt it to theory.
Man can learn nothing unless he proceeds from the known to the unknown.
The terrain is everything; the germ is nothing,
Hatred is the most clear- sighted, next to genius....
We achieve more than we know. We know more than we understand. We understand more than we can explain.
Science rejects the indeterminate.
But while I accept specialization in the practice, I reject it utterly in the theory of science.
The fact that knowledge endlessly recedes as the investigator is about to grasp it is what constitutes at the same time his torment and happiness.
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.
As soon as the circumstances of an experiment are well known, we stop gathering statistics. ... The effect will occur always without exception, because the cause of the phenomena is accurately defined. Only when a phenomenon includes conditions as yet undefined,Only when a phenomenon includes conditions as yet undefined, can we compile statistics. ... we must learn therefore that we compile statistics only when we cannot possibly help it; for in my opinion, statistics can never yield scientific truth.
Ardent desire for knowledge, in fact, is the one motive attracting and supporting investigators in their efforts; and just this knowledge, really grasped and yet always flying before them, becomes at once their sole torment and their sole happiness. Those who do not know the torment of the unknown cannot have the joy of discovery which is certainly the liveliest that the mind of man can ever feel.
Obervation is a passive science, experimentation is an active science.
Particular facts are never scientific; only generalization can establish science.
