That other sort of theorists who held
Mere unintelligence prepared the way
For either seed's upsprouting: you repelled
Their notion that both kinds could sow themselves.
True! but admit 't is understanding delves
And drops each germ, what else but folly thwarts
The doer's settled purpose? Let the sage
Concede a use to evil, though there starts
Full many a burgeon thence, to disengage
With thumb and finger lest it spoil the yield
