Full Idea
You Stoics want to "live according to nature"? Oh you noble Stoics, what fraudulent words! Nature is prodigal and indifferent beyond measure - how could you live by such indifference? Living is wanting to be other than nature.
Clarification
'Prodigal' here means overflowing with variety
Gist of Idea
Nature is totally indifferent, so you should try to be different from it, not live by it
Source
Friedrich Nietzsche (Beyond Good and Evil [1886], §009)
Book Reference

A Reaction
I think this is simply indicative of the slide from optimism to pessimism about nature in the intervening centuries. Stoics thought nature rational. See 'King Lear' for the transition.
