The mental never influences the physical. It is always the physical that modifies the mental, and when we think that the mind is diseased, it is always an illusion.

Claude Bernard
Image
A contemporary poet has characterized this sense of the personality of art and of the impersonality of science in these words,-'Art is myself science is ourselves. '
Claude Bernard
Image
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.
Claude Bernard
Image
First causes are outside the realm of science.
Claude Bernard
Image
We must alter theory to adapt it to nature, but not nature to adapt it to theory.
Claude Bernard
Image
True science teaches us to doubt and, in ignorance, to refrain.
Claude Bernard
Image
The goal of scientific physicians in their own science ... is to reduce the indeterminate. Statistics therefore apply only to cases in which the cause of the facts observed is still indeterminate.
Claude Bernard
Image
The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
