True science teaches us to doubt and, in ignorance, to refrain.

Claude Bernard

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
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

Delicate Live Mechanism Organism Property Wonderful
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
Feeling alone guides the mind.

Alone Feeling Guide Mindset
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
It is what we know already that often prevents us from learning.
CLAUDE BERNARD

Deep Knowledge Learning Ourselves Prevent
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
Man can learn nothing unless he proceeds from the known to the unknown.

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

Confirm Control Experiment Simplicity
The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
CLAUDE BERNARD

Believe Doubt Man Science True
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
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

Appearance Discovery Greatness Light Path Rise Shift
Science does not permit exceptions.
CLAUDE BERNARD

Exception One Liner Science
