This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book considers the relation of Rödl exposition of the categories of the temporal “at the most abstract level” with possible, more specific metaphysical-logical extensions thereof: Laws of reason and laws of nature are both laws, and not by homonymy. It presents Rödl’s approach, as developed in his Replies, in grouping various “post-naturalist” philosophies together under three headings: formal idealism, quietism, and absolute idealism. The book explores quietism: the quietist agrees with formal idealism and SC&O’s absolute idealism on the incoherence of naturalism, yet she contends that both are mistaken in assuming that there is, then, still room for discussing judgment at all. The book discusses formal idealism and quietism in relation to SC&O’s absolute idealism.
