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

Claude Bernard

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
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
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

Active Creation Experiment Head Limitation Nature Progress Science
The stability of the internal medium is a primary condition for the freedom and independence of certain living bodies in relation to the environment surrounding them.
CLAUDE BERNARD

Body Environment Freedom Independence Live Medium Stability
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
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
Science rejects the indeterminate.
CLAUDE BERNARD

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

Establishment Fact General Science
Science does not permit exceptions.
CLAUDE BERNARD

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

Deep Knowledge Learning Ourselves Prevent
The first requirement in using statistics is that the facts treated shall be reduced to comparable units.
CLAUDE BERNARD

Compare Requirement Statistics Treat
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 goal of scientific physicians in their own science … is to reduce the indeterminate. Statistics therefore apply only to cases in which the cause of the facts observed is still indeterminate.
CLAUDE BERNARD

Determination Fact Goal Reason Reduce 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
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
