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

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
The experimenter who does not know what he is looking for will not understand what he finds.
CLAUDE BERNARD

Experiment Himself Philosophy Research Understand
It is what we know already that often prevents us from learning.
CLAUDE BERNARD

Deep Knowledge Learning Ourselves Prevent
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
Particular facts are never scientific; only generalization can establish science.
CLAUDE BERNARD

Establishment Fact General 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

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

Believe Enough Firm Man Seek Theory Truth
The minds that rise and become really great are never self-satisfied, but still continue to strive.
CLAUDE BERNARD

Greatness Mindset Rise Satisfaction Strive
Hatred is the most clear- sighted, next to genius.
CLAUDE BERNARD

Clear Genius Hate
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

We must never make experiments to confirm our ideas, but simply to control them.
CLAUDE BERNARD

Confirm Control Experiment Simplicity
But while I accept specialization in the practice, I reject it utterly in the theory of science.
CLAUDE BERNARD
