Nietzsche's dynamic contradictiousness has served as a source for the kind of static, somnolent, undiscriminating, sceptical tolerance which seems to be expressed by the claim to have stopped believing in sin. Readiness to question everything mutates mysteriously into a pose of equal indifference to all possible answers. Can this be more than pose? That it often is a pose, lasting only till the owner's moral corns happen to be trodden on, is by now a common observation. (The shocked immoralist in Tom Stoppard's play Professional Foul is a nice case.) But this is not just an unfair joke by satirists. What else could the undiscriminating position be? It is scarcely possible to vindicate it as a stern attempt to stand by one's moral principles, and remain indifferent in the face of all temptation to do otherwise.
