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

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

Admit Determination Exception Science
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
The great experimental principle, then, is doubt, that philosophic doubt which leaves to the mind its freedom and initiative, and from which the virtues most valuable to investigators in physiology and medicine are derived.
CLAUDE BERNARD

Doubt Experiment Freedom Greatness Leave Medicine Mindset Principle Virtue
We must never make experiments to confirm our ideas, but simply to control them.
CLAUDE BERNARD

Confirm Control Experiment Ideas Simplicity
A fact in itself is nothing. It is valuable only for the idea attached to it, or for the proof which it furnishes.
CLAUDE BERNARD

Attachment Evidence Fact Ideas Value
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

Condition Environment Object Oneself Preserve
But while I accept specialization in the practice, I reject it utterly in the theory of science.
CLAUDE BERNARD

Acceptance Myself Practice Science Theory
A discovery is generally an unforeseen relation not included in theory.
CLAUDE BERNARD

Discover General Theory
The true worth of an experimenter consists in his pursuing not only what he seeks in his experiment, but also what he did not seek.
CLAUDE BERNARD

Experiment Himself Seek True Worth
In science, the best precept is to alter and exchange our ideas as fast as science moves ahead.
CLAUDE BERNARD

Ahead exchange Fast Ideas Move Science
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

Beautiful Imagination Ourselves Science Truth
When entering on new ground we must not be afraid to express even risky ideas so as to stimulate research in all directions. As Priestley put it, we must not remain inactive through false modesty based on fear of being mistaken.
CLAUDE BERNARD

Afraid Direction Fear Ground Ideas Mistake Modesty Risk
Feeling alone guides the mind.
CLAUDE BERNARD

Alone Feeling Guide Mindset
Priestley said that each discovery we make shows us many others that should be made.
CLAUDE BERNARD

The terrain is everything; the germ is nothing.
CLAUDE BERNARD

Science does not permit exceptions.
