We Amuse Ourselves Painting Our Prison-walls With

Happy Contractedness Of Youth, Nay, Of Mankind In General, That They Think Neither Of The High Nor The Deep, Of The True Nor The False, But Only Of What Is Suited To Their Own Conceptions.

Whatever You Can Do Or Dream, Begin It.

Girls We Love For What They Are; Young Men For What They Promise To Be.

How Many Years Must A Man Do Nothing, Before He Can At All Know What Is To Be Done And How To Do It!

Hypotheses Are Only The Pieces Of Scaffolding Which Are Erected Round A Building During The Course Of Construction, And Which Are Taken Away As Soon As The Edifice Is Completed.
