The decline of the truth of beings occurs necessarily, and indeed as the completion of metaphysics.

The decline occurs through the collapse of the world characterized by metaphysics, and at the same time through the desolation of the earth stemming from metaphysics.

Collapse and desolation find their adequate occurrence in the fact that metaphysical man, the animal rationale, gets fixed as the laboring animal.

This rigidification confirms the most extreme blindness to the oblivion of Being. But man wills himself as the volunteer of the will to will, for which all truth becomes that error which it needs in order to be able to guarantee for itself the illusion that the will to will can will nothing other than empty nothingness, in the face of which it asserts itself without being able to know its own completed nullity.

Before Being can occur in its primal truth, Being as the will must be broken, the world must be forced to collapse and the earth must be driven to desolation, and man to mere labor. Only after this decline does the abrupt dwelling of the Origin take place for a long span of time. In the decline, everything, that is, beings in the whole of the truth of metaphysics, approaches its end.

The decline has already taken place. The consequences of this occurrence are the events of world history in this century. They are merely the course of what has already ended. Its course is ordered historico-technologically in the sense of the last stage of metaphysics. This order is the last arrangement of what has ended in the illusion of a reality whose effects work in an irresistible way, because they claim to be able to get along without an unconcealment of the essence of Being. They do this so decisively that they need suspect nothing of such an unconcealment.
