Art is I; science is we
The experimenter who does not know what he is looking for will not understand what he finds
In teaching man, experimental science results in lessening his pride more and more by proving to him every day that primary causes, like the objective reality of things, will be hidden from him forever and that he can only know relations
It is what we know already that often prevents us from learning
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.
A fact in itself is nothing. It is valuable only for the idea attached to it, or for the proof which it furnishes.
Mediocre men often have the most acquired knowledge
Man can learn nothing except by going from the known to the unknown.
Observation is a passive science, experimentation an active 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.
It's what we think we know that keeps us from learning.
The science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen.
If I had to define life in a word, it would be: Life is creation.
Science increases our power in proportion as it lowers our pride.
A modern poet has characterized the personality of art and the impersonality of science as follows: Art is I: Science is We.
