Claude Bernard was a French physiologist. Historian I. 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. He was the first to define the term milieu intérieur, now known as homeostasis.
Mediocre men often have the most acquired knowledge.
The investigator should have a robust faith - and yet not believe.
Observation is a passive science, experimentation an active science.
Science does not permit exceptions.
It is what we know already that often prevents us from learning.
Art is I science is we.
Experimentation is an active science.
