Obervation is a passive science, experimentation is an active science.

Claude Bernard

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
Science rejects the indeterminate.
CLAUDE BERNARD

Determination Rejection Science
The first requirement in using statistics is that the facts treated shall be reduced to comparable units.
CLAUDE BERNARD

Compare Requirement Statistics Treat
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

Average Darkness Greatness Knowledge Man Recognition Science
Priestley said that each discovery we make shows us many others that should be made.
CLAUDE BERNARD

Discover Science Show
When we meet a fact which contradicts a prevailing theory, we must accept the fact and abandon the theory, even when the theory is supported by great names and generally accepted.
CLAUDE BERNARD

Abandonment Acceptance Believe Conflict Fact Intuition Support Theory
Obervation is a passive science, experimentation is an active science.
CLAUDE BERNARD

Active Experiment Observation Passive Science
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
We must never make experiments to confirm our ideas, but simply to control them.
CLAUDE BERNARD

Confirm Control Experiment Simplicity
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
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

Climb Horizon Necessary Proportion Science Theory
The experimenter who does not know what he is looking for will not understand what he finds.
CLAUDE BERNARD

Experiment Himself Philosophy Research Understand
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
Science does not permit exceptions.
CLAUDE BERNARD

Exception One Liner Science
With the aid of these active experimental sciences man becomes an inventor of phenomena, a real foreman of creation; and under this head we cannot set limits to the power that he may gain over nature through future progress of the experimental sciences.
CLAUDE BERNARD

Active Creation Experiment Head Limitation Nature Progress Science
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
