Art is I; Science is We.
Man can learn nothing except by going from the known to the unknown.
It is what we know already that often prevents us from learning.
The experimenter who does not know what he is looking for will not understand what he finds.
Science increases our power in proportion as it lowers our pride.
Man can learn nothing unless he proceeds from the known to the unknown.
Those who do not know the torment of the unknown cannot have the joy of discovery.
The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
Hatred is the most clear- sighted, next to genius...
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.
Descriptive anatomy is to physiology what geography is to history, and just as it is not enough to know the typography of a country to understand its history, so also it is not enough to know the anatomy of organs to understand their functions.
True science teaches us to doubt and, in ignorance, to refrain.
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.
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.
