The pseudonymous author of the Philosophical Crumbs and its Concluding Unscientific Postscript, Johannes Climacus, describes himself as a "humorist". This chapter discusses his account of the roles for irony and humor as confinia, or boundaries, between the aesthetic, ethical, and religious existence-spheres. Irony and humor serve as "incognitos" for ethical and religious existence and play significant roles in ethical and religious development. The Postscript contains the most famous Søren Kierkegaardian satire, ostensibly at the expense of Hegelianism. The chapter considers how Climacus' ostensibly anti-Hegelian satire might rebound on his readers, and aspects of the "way out" central to the "legitimacy" of the comic. For Christianity, the "way out" would ultimately have to be eschatological. That belief, for the Christian, is indeed eschatological: faith in a God who "will prevail in the end", such that the essential suffering of life need not be experienced as utterly overwhelming.
