Nothing
Hegel (Logic of Being, the beginning)
The beginning of the Logic after Being. Not empirical emptiness, but the thought-determination "Nothing." Immediately identical with Being --- both are utterly indeterminate. Their truth is Becoming.
Origin
Parmenides: Nothing is unthinkable. Hegel: Nothing is thinkable as pure indeterminacy --- and identical with Being.
