But while I accept specialization in the practice, I reject it utterly in the theory of science.

Claude Bernard

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
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

Condition Force Law Manifestation State
Hatred is the most clear- sighted, next to genius.
CLAUDE BERNARD

Clear Genius Hate
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
Those who have an excessive faith in their theories or in their ideas are not only poorly disposed to make discoveries, but they also make very poor observations.
CLAUDE BERNARD

Excess Faith Ideas Observation Poor Theory
It is what we know already that often prevents us from learning.
CLAUDE BERNARD

Deep Knowledge Learning Ourselves Prevent
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
Science increases our power in proportion as it lowers our pride.
CLAUDE BERNARD

Lower Ourselves Power Pride 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
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 rejects the indeterminate.
CLAUDE BERNARD

Determination Rejection 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
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 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
Obervation is a passive science, experimentation is an active science.
CLAUDE BERNARD

Active Experiment Observation Passive Science
Feeling alone guides the mind.
CLAUDE BERNARD

Alone Feeling Guide Mindset
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
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
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
First causes are outside the realm of science.
CLAUDE BERNARD

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

Discover Feeling Live 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

In the philosophic sense, observation shows and experiment teaches.
CLAUDE BERNARD

Experiment Observation Philosophy Teaching
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.
