the world resembleth man, in that it hath a backside,—SO MUCH is true!
There is in the world much filth: SO MUCH is true! But the world itself is not therefore a filthy monster!
There is wisdom in the fact that much in the world smelleth badly: loathing itself createth wings, and fountain-divining powers!
In the best there is still something to loathe

Context

“For these are all unclean spirits; especially those, however, who have no peace or rest, unless they see the world FROM THE BACKSIDE—the backworldsmen! TO THOSE do I say it to the face, although it sound unpleasantly: the world resembleth man, in that it hath a backside,—SO MUCH is true! There is in the world much filth: SO MUCH is true! But the world itself is not therefore a filthy monster! There is wisdom in the fact that much in the world smelleth badly: loathing itself createth wings, and fountain-divining powers! In the best there is still something to loathe; and the best is still something that must be surpassed!— O my brethren, there is much wisdom in the fact that much filth is in the world!— 15. Such sayings did I hear pious backworldsmen speak to their consciences, and verily without wickedness or guile,—although there is nothing more guileful in the world, or more wicked.” source
