He who is firm in will molds the world to himself.

The schools must fashion the person, and fashion him in such a way that he simply cannot will otherwise than what you wish him to will.

I know what I can know, and am not troubled about what I cannot know.

Not alone to know, but to act according to thy knowledge, is thy destination,--proclaims the voice of my inmost soul. Not for indolent contemplation and study of thyself, nor for brooding over emotions of piety,--no, for action was existence given thee; thy actions, and thy actions alone, determine thy worth.
