Knowing of Not-Knowing: the Outlines of a Critical Skepticism

Abstract

Abstract Sextus Empiricus’ definition of skepticism as a search for truth still poses great problems for research today. Perhaps the most urgent of these is: How can we reasonably assert the possibility of knowledge and at the same time deny its reality? The paper tries to solve this question by drawing attention to a hitherto neglected variant of skepticism: the so-called critical skepticism. In confrontation with Hume and Kant, Salomon Maimon develops a skeptical position which, with the help of transcendental argumentation, produces a knowing of not-knowing. Maimon defends with Kant (and against Hume) transcendental knowledge which at the same time offers a reason to reject with Hume and against Kant empirical knowledge. By doing so, he distinguishes a knowledge of possibility from a (non-)knowledge of reality, whereby the search for truth—expressed in the assumption that knowledge is possible—is and remains the only truth.
