Science does not permit exceptions.

Claude Bernard

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

Experiment Observation Philosophy Teaching
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
Man can learn nothing unless he proceeds from the known to the unknown.
CLAUDE BERNARD

Learning Man Unknown
Everything is poisonous, nothing is poisonous, it is all a matter of dose.

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

Deep Knowledge Learning Ourselves Prevent
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
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
Experiment is fundamentally only induced observation.
CLAUDE BERNARD

Experiment Fundamental Observation
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
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
First causes are outside the realm of science.
CLAUDE BERNARD

Reason 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
With the aid of these active experimental sciences man becomes an inventor of phenomena, a real foreman of creation; and under this head we cannot set limits to the power that he may gain over nature through future progress of the experimental sciences.
CLAUDE BERNARD
