Was ist erlaubt?

Theodore Dalrymple kommentiert im City Journal den deutschen Kannibalismus-Prozess kurz und heftig: Ist zwischen Menschen alles erlaubt, sofern sie nur frei zustimmen? Falls nicht, was sind diese ersten Prinzipien, die es verbieten?

"The case is a reductio ad absurdum of the philosophy according to which individual desire is the only thing that counts in deciding what is permissible in society. Brandes wanted to be killed and eaten; Meiwes wanted to kill and eat. Thanks to one of the wonders of modern technology, the Internet, they both could avoid that most debilitating of all human conditions, frustrated desire. What is wrong with that? Please answer from first principles only."
