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

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

Illusion Influence Mental Mindset Thinking
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

Built Death Fact Material Observation Science
Science does not permit exceptions.
CLAUDE BERNARD

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

Condition Force Law Manifestation State
Those who do not know the torment of the unknown cannot have the joy of discovery.

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

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

Science admits no exceptions; otherwise there would be no determinism in science, or rather, there would be no science.
CLAUDE BERNARD

Man can learn nothing unless he proceeds from the known to the unknown.

In the philosophic sense, observation shows and experiment teaches.

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.
