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.

More quotes by Claude Bernard

Image
In the philosophic sense, observation shows and experiment teaches.
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
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
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
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
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
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
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
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
Obervation is a passive science, experimentation is an active science.
Claude Bernard
Image
Science admits no exceptions otherwise there would be no determinism in science, or rather, there would be no science.
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
The stability of the internal medium is a primary condition for the freedom and independence of certain living bodies in relation to the environment surrounding them.
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.
Claude Bernard
Image
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.
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
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
If I had to define life in a single phrase, I should clearly express my thought of throwing into relief one characteristic which, in my opinion, sharply differentiates biological science. I should say: life is creation.
Claude Bernard
Image
Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.
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.
