This article provides an account of the Enlightenment dispute over hermeneutical skepticism with particular reference to the idea of hermeneutical probability in the philosophical work of Christian August Crusius. The essay sheds new light on the hermeneutical issues addressed in the philosophical school of the so-called Thomasians based mainly in Leipzig in the first half of the eighteenth century. The paper deals with Crusius’ wide-ranging efforts to cope with the uncertain character of most parts of human knowledge and his attempts (...) to construct a workable theory of hermeneutical probability. This raises points of central interest relating to probabilism in the methodology of textual interpretation and connects Crusius to contemporary discussions of hermeneutical skepticism. (shrink)
