Ulrich Horstmann

Ulrich Horstmann is a German literary scholar and writer who has also written under the pseudonym Klaus Steintal. Frequently described as a philosopher in the tradition of philosophical pessimism, he is perhaps most notorious for his view, often regarded as extreme even among other pessimist philosophers, that voluntary human extinction ought to be achieved by way of intentional global thermonuclear annihilation. Horstmann developed an idea of anthropofugal thinking in his philosophical essay "Das Untier" (1983).
