Philosophy often at least implicitly includes and depends on a logical structure which is also that of jokes. This is the case when philosophy involves questioning or establishing concepts in their own right, and when it involves the kinds of metaphysics which ask about reality and the world as a wholeor as such. Taking this humour-like structure into account in presenting philosophy helps, among otherthings, to lay open part of the character of philosophy itself, to underscore the radical self-perspective thatis constitutive of philosophy, and to contextualise the often confusing experience of coming to grips with anunfamiliar philosophical framework.
