The Scariest Passage in the Critique of Pure Reason

With Halloween upon us, it is appropriate that I should present to my esteemed readers for their delectation if not horror the scariest passage in Kant's magnum opus:

Unconditioned necessity, which we so indispensably require as the last bearer of all things, is for human reason the veritable abyss. . . . We cannot put aside, and  yet also cannot endure the thought, that a being, which we represent to ourselves as supreme among all possible beings, should, as it were, say to itself: 'I am from eternity to eternity, and outside of me there is nothing save what is through my will, but whence then am I? (A613 B641)

Interpretation later.
