Allerdings ist das Leben nicht eigentlich da, um genossen, sondern um überstanden, abgethan zu werden... - Arthur Schopenhauer

No rose without a thorn. Yes, but many a thorn without a rose.

To free a man from error is not to deprive him of anything but to give him something: for the knowledge that a thing is false is a piece of truth. No error is harmless: sooner or later it will bring misfortune to him who harbours it. Therefore deceive no one, but rather confess ignorance of what you do not know, and leave each man to devise his own articles of faith for himself.

To become reconciled to a friend with whom you have broken, is a form of weakness; and you pay the penalty of it when he takes the first opportunity of doing precisely the very thing which brought about the breach.
