The law appears at first in the form of a fundamental principle which presupposes identity as a characteristic of Being, that is, of the ground of beings. This principle in the sense of a statement has in the meantime become a principle bearing the characteristics of a spring that departs from Being as the ground of beings, and thus springs into the abyss. But this abyss is neither empty nothingness nor murky confusion, but rather: the event of appropriation. In the event of appropriation vibrates the active nature of what speaks as language, which at one time was called the house of Being. “Principle of identity” means now: a spring demanded by the essence of identity because it needs that spring if the belonging together of man and Being is to attain the essential light of the appropriation.
