More quotes by 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
The science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen.
Claude Bernard
Image
The terrain is everything the germ is nothing.
Claude Bernard
Image
Those who do not know the torment of the unknown cannot have the joy of discovery.
Claude Bernard
Image
Effects vary with the conditions which bring them to pass, but laws do not vary. Physiological and pathological states are ruled by the same forces they differ only because of the special conditions under which the vital laws manifest themselves.
Claude Bernard
Image
Theories are like a stairway by climbing, science widens its horizon more and more, because theories embody and necessarily include proportionately more facts as they advance.
Claude Bernard
Image
Mediocre men often have the most acquired knowledge
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
Obervation is a passive science, experimentation is an active science.
Claude Bernard
Image
It is what we know already that often prevents us from learning.
Claude Bernard
Image
The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
Claude Bernard
Image
Men who believe too firmly in their theories, do not believe enough in the theories of others. So ... these despisers of their fellows ... make experiments only to destroy a theory, instead of to seek the truth.
Claude Bernard
Image
Hatred is the most clear- sighted, next to genius.
Claude Bernard
Image
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
Image
Well-observed facts, though brought to light by passing theories, will never die they are the material on which alone the house of science will at last be built.
Claude Bernard
Image
We must alter theory to adapt it to nature, but not nature to adapt it to theory.
Claude Bernard
Image
The experimenter who does not know what he is looking for will not understand what he finds.
Claude Bernard
Image
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
We achieve more than we know. We know more than we understand. We understand more than we can explain.
Claude Bernard
Image
Il ne fallait jamais faire des expériences pour confirmer ses idées, mais simplement pour les contrôler. We must never make experiments to confirm our ideas, but simply to control them.
