Although I am an intellectual---indeed, precisely because of this fact---I realize, perhaps better than other people do, the great truth that intellect is not everything. I know that reason has two limits, the upper and the lower. The upper limit is formed by the axioms on which our scientific systems are based. We cannot go beyond that limit, and in the choice of axioms we must be guided not by reason but by what we usually call intuition. The lower limit is formed by individual unrepeatable facts which cannot be interpreted by any consequences deduced from general laws and from axioms.
