The person who is considered pure-minded, but who has no experience of the world and who does not know good or evil, has no credit; he is a simpleton. He is no better than a rock. A rock does not know what is evil. The greatness of man is that he goes through all this which takes away that purity of mind with which man is born - and rises through it, not being pushed under - but holding to its original purity, rising above all that pulls him down and keeps him down on the earth. It is a kind of fight throughout life. He who has no cause to fight, he does not know life. He is perhaps an angelic person, perhaps a pious person, and that we can call him out of respect; but plainly speaking, he is a simpleton.
