Wittgenstein’s appeal lies in the fact that he provides a strange kind of vindication of romanticism, of conceptual Gemeinschaft, of custom-based concepts rather than statute-seeking Reform, and that he does so through a very general theory of meaning, rather than from the premisses habitually used for this purpose. Because there is no unique formal notation valid for all speech, each and every culture is vindicated. One never knew that could be done—and so quickly too! It is that above all which endows his philosophy with such a capacity to attract and to repel. His mystique of consensual custom denies that anything can sit in judgment of our concepts, that some may be more rational and others less so. So all of them are in order and have nothing to fear from philosophy, as indeed he insists. This is a fairly mild form of irrationalism, invoking no fierce dark Gods, merely a consensual community. It is the Soft Porn of Irrationalism.
