The fate of an epoch that has eaten of the tree of knowledge is that it must...recognize that general views of life and the universe can never be the products of increasing empirical knowledge, and that the highest ideals, which move us most forcefully, are always formed only in the struggle with other ideals which are just as sacred to others as ours are to us.

It is true that the path of human destiny cannot but appal him who surveys a section of it. But he will do well to keep his small personal commentarie to himself, as one does at the sight of the sea or of majestic mountains, unless he knows himself to be called and gifted to give them expression in artistic or prophetic form.
