Genius is one of the many forms of insanity.
The ignorant man always adores what he cannot understand
God and I both knew what it meant once; now God alone knows.
The appearance of a single great genius is more than equivalent to the birth of a hundred mediocrities
Unfortunately, goodness and honor are rather the exception than the rule among exceptional men, not to speak of geniuses
Good sense travels on the well-worn paths; genius, never. And that is why the crowd, not altogether without reason, is so ready to treat great men as lunatics.
