Unfortunately I was unable to get in touch with the author, who has the copyright, and whose e-mail address has changed without notice. For this reason I cannot post the original paper. I would be grateful for information on how to reach him. Metaphysics has come to an end' because its essential possibilities have been exhausted. For Descartes the ego cogito is the ground, what is certain, what is already represented and produced in all thoughts.
Truth thereby becomes certainty.
This certainty is in the subject. The subject becomes reason existing in and for itself, the animal rationale. Heidegger calls Nietzsche's position 'metaphysics of subjectivity'. It is the subjectivity of the body. This reversal of Platonism, this making the body absolutely valid, exhausts the last possibility of metaphysics - i.e. its reversal'.
