"And since all things have been named light and night and things corresponding to their powers for each, everything is full alike of light and invisible night, both equal since nothing has a share in neither"
About this Quote
Parmenides is trying to short-circuit your most basic mental habit: carving the world into opposites and then treating those opposites as if they were the world. Light and night sound like a clean, intuitive pair - presence and absence, knowledge and ignorance, being and not-being. He invokes naming on purpose. The moment you label forces, you start believing the labels track real divisions in reality rather than convenient handles for human sense-making.
The line’s odd pivot - “invisible night” and then the claim that everything is “full alike” of both - is where the philosophy turns combative. If everything participates equally in light and night, then neither can function as an absolute principle. You can’t explain reality by saying “it’s made of X” if X only makes sense against its negation. The subtext is a warning: dualisms seduce because they’re rhetorically tidy, not because they’re metaphysically sound.
Context matters. Parmenides is writing against the early Greek impulse to build cosmologies out of elemental rivals and flux (think Heraclitus’s churn). His deeper target is “nothing” itself. “Nothing has a share in neither” reads like a riddle, but it’s a trapdoor: non-being cannot be part of the inventory of what is. So any theory that smuggles “not-being” in as a real ingredient (as darkness often is, poetically) collapses.
It works because it weaponizes poetry - light, night, fullness - to argue for an austere thesis: reality can’t be grounded in contrasts without quietly granting reality to the void.
