Abstract

The time of „philosophical systems“ seems to be definitively over since Kant and Hegel. On this background, the publication of the work „Neues System der philosophischen Wissenschaften im Grundriss“ (New System of Philosophical Sciences in Ground Plan) is a truly spectacular philosophical event: Dirk Hartmann deliberately follows Hegel‘s „Enzyklopädie der philosophischen Wissenschaften im Grundrisse“ of 1817 in the title of his work, in order to make clear the intention and claim of his opus magnum: In contrast to the increased fragmentation and specialization of philosophy in the 20th century, Hartmann focuses on the philosophical treatment of the whole: In seven volumes, he discusses the classical philosophical problems in their interdependent context, not cataloguing them one after the other, but by consistently developing them from one another. Volume I deals with central epistemological problems: „What is knowledge?“, „Is knowledge even possible?“, „Are there forms of substantial non-empirical truth?“, „Is there an ideal language?“, „Can logic be reasoned?“ and „What is science?”. Since this is the first volume of the entire system, the question „What is philosophy?“ is raised at the very beginning too, and the reasons why philosophy should begin with epistemology are expounded. Finally, the criterion of meaning guiding the entire work, the principle of knowability, is justified and defended against pertinent objections.
