Infinitely Divisible
No new reality can originate, therefore
everything existed since always
 reality reducible to an infinite number of
“seeds.”
– “seeds” contain elements of everything and
are in everything (some more than others)
– “Everything participates in everything“
– Particles originally in huge mass that began
separating… how??

impersonal MIND
– Not mixed with anything
 Gives
order and constancy to universe

things
– Differentiates them from dead matter

always returns to whirlpool motion
promoted by nous
