Claude Bernard, born on July 12, 1813, was a distinguished French physiologist and pioneer in the field of experimental medicine. His groundbreaking research and scientific contributions revolutionized our understanding of the human body and its functions. Bernard’s emphasis on experimentation and rigorous scientific methodology helped establish the foundations of modern physiology. He is particularly known for his work on the concept of homeostasis, which explains the body’s ability to maintain a stable internal environment. Bernard’s relentless pursuit of scientific truth and his commitment to empirical evidence laid the groundwork for future advancements in medicine and biology. His legacy as a brilliant scientist and visionary thinker continues to shape the field of physiology to this day.
The true worth of an experimenter consists in his pursuing not only what he seeks in his experiment, but also what he did not seek.

The investigator should have a robust faith – and yet not believe.

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.

Art is I; science is we.

Experimentation is an active science.

It is what we know already that often prevents us from learning.

Man can learn nothing except by going from the known to the unknown.

A fact in itself is nothing. It is valuable only for the idea attached to it, or for the proof which it furnishes.
