The best are the worst
Only a few ever make it to the top. At each stage in their advancement a sieve was applied to catch the valuable ones and let the rubbish escape. A sieve always catches the gross and lets the fine escape. Thus, after many applications of the sieve, only those who most promote worldly values are left - the grossest of the gross.
Nietzsche has no end of praise for these heroes:
"Diligent in business - but indolent of spirit, content with your inadequacy, and with the cloak of duty hung over your discontentment: that is how you live, that is how you want your children to live!"
