 One abiding characteristic of Hamann’s many responses to the philosophy of his time, therefore, is this ‘metacritical’ instinct: not to construct a rival account, but to go for the jugular; not to set up a rival critique, but to insist that critique itself must be subject to meta-critique, which concerns itself with the issues that must be attended to in relation to the act of philosophical reflection itself. It consists of attention to the fundamental stance or position on issues or insights that must underlie any work on philosophy or theology. According to Hamann, often “the difficulties lie in womb of the concepts” (N III, 31, 21). Hamann’s writing therefore is not so much ‘unsystematic’ as is sometimes said, but ‘presystematic’. He addresses issues that must be recognized in any self-critical reflection, matters that must be presuppositions for any system. Thus one of the most salient features of his “Metacritique of the Purism of Reason”, his unpublished response to Kant’s Critique of Pure Reason, was to focus on the question of language. Through a tissue of imagery, he suggests that a proper view of language implies that the alleged ‘purity’ of a priori reason is untenable.
