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.

More quotes by Claude Bernard

Image
Science does not permit exceptions.
Claude Bernard
Image
The eloquence of a scientist is clarity scientific truth is always more luminous when its beauty is unadorned than when it is tricked out in the embellishments with which our imagination would seek to clothe it.
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
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
A great discovery is a fact whose appearance in science gives rise to shining ideas, whose light dispels many obscurities and shows us new paths.
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
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 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
All the vital mechanisms, varied as they are, have only one object, that of preserving constant the conditions of life in the internal environment.
Claude Bernard
Image
Progress is achieved by exchanging our theories for new ones which go further than the old, until we find one based on a larger number of facts. ... Theories are only hypotheses, verified by more or less numerous facts. Those verified by the most facts are the best, but even then they are never final, never to be absolutely believed.
Claude Bernard
Image
Science increases our power in proportion as it lowers our pride.
Claude Bernard
Image
It is what we know already that often prevents us from learning.
Claude Bernard
Image
A discovery is generally an unforeseen relation not included in theory.
Claude Bernard
Image
Obervation is a passive science, experimentation is an active science.
Claude Bernard
Image
Put off your imagination, as you put off your overcoat, when you enter the laboratory. Put it on again, as you put on your overcoat, when you leave.
Claude Bernard
Image
The experimenter who does not know what he is looking for will not understand what he finds.
Claude Bernard
Image
Proof that a given condition always precedes or accompanies a phenomenon does not warrant concluding with certainty that a given condition is the immediate cause of that phenomenon. It must still be established that when this condition is removed, the phenomen will no longer appear.
Claude Bernard
Image
Those who do not know the torment of the unknown cannot have the joy of discovery.
Claude Bernard
Image
Hatred is the most clear- sighted, next to genius.
Claude Bernard

First causes are outside the realm of science.
