The case with most men is that they go out into life with one or another accidental characteristic of personality of which they say: Well, this is the way I am. I cannot do otherwise. Then the world gets to work on them and thus the majority of men are ground into conformity. In each generation a small part cling to their "I cannot do otherwise" and lose their minds. Finally there are a very few in each generation who in spite of all life's terrors cling with more and more inwardness to this "I cannot do otherwise". They are the geniuses. Their "I cannot do otherwise" is an infinite thought, for if one were to cling firmly to a finite thought, he would lose his mind.
Søren Aabye Kierkegaard
