Death. The certain prospect of death could sweeten every life with a precious and fragrant drop of levity- and now you strange apothecary souls have turned it into an ill-tasting drop of poison that makes the whole of life repulsive.
This is the manner of noble souls: they do not want to have anything for nothing; least of all, life. Whoever is of the mob wants to live for nothing; we others, however, to whom life gave itself, we always think about what we might best give in return...
One should not wish to enjoy where one does not give joy.
Friedrich Nietzsche (1844 - 1900)
