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.
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.
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.
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.
