In science, the best precept is to alter and exchange our ideas as fast as science moves ahead.

Claude Bernard

Particular facts are never scientific; only generalization can establish science.
CLAUDE BERNARD

Establishment Fact General Science
In the philosophic sense, observation shows and experiment teaches.
CLAUDE BERNARD

Experiment Observation Philosophy Teaching
We must remain, in a word, in an intellectual disposition which seems paradoxical, but which, in my opinion, represents the true mind of the investigator. We must have a robust faith and yet not believe.
CLAUDE BERNARD

Believe Faith Intellectual Opinion Word
Priestley said that each discovery we make shows us many others that should be made.
CLAUDE BERNARD

Discover Science Show
Science rejects the indeterminate.
CLAUDE BERNARD

Determination Rejection Science
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
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
Mediocre men often have the most acquired knowledge.
CLAUDE BERNARD

It is what we know already that often prevents us from learning.
CLAUDE BERNARD

Deep Knowledge Learning Ourselves Prevent
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
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
Those who do not know the torment of the unknown cannot have the joy of discovery.
CLAUDE BERNARD

Discover Hard Time Joy Struggle
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

Break Change Enough Ideas Instrument Intellectual Purpose
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
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

Imagination Leaving Science Yourself
Obervation is a passive science, experimentation is an active science.
CLAUDE BERNARD

Active Experiment Observation Passive Science
