Being loves (a) self-concealing

Discussed in The Principle of Reason, page 64.

In this article on Heidegger Thomas Sheehan has a different translation.

[T]he very structure of disclosure -- i.e., the fact that the absent-but-anticipated determines or "gives" finite presence -- entails that its ultimate source remain intrinsically hidden even while disclosing the being of entities. This intrinsic hiddenness at the core of disclosure is what Heidegger calls the "mystery." Heidegger argued that the "mystery" was the ultimate issue in philosophy, and he believed Heraclitus had said as much in his fragment no. 123: "Disclosure-as-such loves to hide."
