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

Claude Bernard

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
If I had to define life in a single phrase, I should clearly express my thought of throwing into relief one characteristic which, in my opinion, sharply differentiates biological science. I should say: life is creation.
CLAUDE BERNARD

Character Clear Creation Expression Life Science
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
Those who do not know the torment of the unknown cannot have the joy of discovery.
CLAUDE BERNARD

Discover Hard Time Joy Struggle
Art is ‘I’; science is ‘we’.
CLAUDE BERNARD

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

Confirm Control Experiment Simplicity
The joy of discovery is certainly the liveliest that the mind of man can ever feel.
CLAUDE BERNARD

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

Deep Knowledge Learning Ourselves Prevent
A discovery is generally an unforeseen relation not included in theory.
CLAUDE BERNARD

Discover General Theory
But while I accept specialization in the practice, I reject it utterly in the theory of science.
CLAUDE BERNARD

Acceptance Myself Practice Science Theory
The better educated we are and the more acquired information we have, the better prepared shall we find our minds for making great and fruitful discoveries.
CLAUDE BERNARD

Better Discover Education Information Mindset
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 fact that knowledge endlessly recedes as the investigator is about to grasp it is what constitutes at the same time his torment and happiness.
CLAUDE BERNARD

Constitute End Fact Happiness Hard Time Knowledge
True science teaches us to doubt and, in ignorance, to refrain.
CLAUDE BERNARD

Doubt Ignorance Science Teaching True
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
Obervation is a passive science, experimentation is an active science.
CLAUDE BERNARD

Active Experiment Observation Passive Science
We must keep our freedom of mind, and must believe that in nature what is absurd, according to our theories, is not always impossible.
CLAUDE BERNARD

Absurd Believe Freedom Impossible Mindset Nature
Experiment is fundamentally only induced observation.
CLAUDE BERNARD

Experiment Fundamental Observation
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
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
The terrain is everything; the germ is nothing.
CLAUDE BERNARD

Germs Insect Land Terrain
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
The minds that rise and become really great are never self-satisfied, but still continue to strive.
CLAUDE BERNARD

Greatness Mindset Rise Satisfaction Strive
We achieve more than we know. We know more than we understand. We understand more than we can explain.
CLAUDE BERNARD

Achievement Explanation Team Work Understand
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
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
