The thought of a thing precedes the thing itself, but not its potentiality. The unthought thing, never certain of its potent "to be" (to be decay’s necessity & increase’s sufficient determination) cannot conceive till thought itself & of things passing, be perpetuated. This means Memory is a power we live by; learn of by the likes of the dead & of sex----our more celebrated among "recent", thoughtful perpetuations (lest we forget gravity, time & emptiness).
