Abstract

This paper submits the state-of-the-art review of the collection of remote articles of Hans Poser, the largest expert on philosophy Leibniz who has devoted to studying of his philosophy more half a century. Specifics of his position, as interpreter of philosophy of Leibniz, the author of this review sees in Poser’s justification of the fundamental character of Leibniz’s doctrine about modalities, signs and language. Underlining of reflexive and system forming character of modal concepts in the Leibniz’s philosophy and also relevance of his doctrine about modal concepts both for modern modal logic, and for the modern theory of the proof and metamathematics is the central point of interpretation of Leibniz’s philosophy by H. Poser. Concerning a question of the relation of science and metaphysics, H. Poser speaks out in defense of metaphysics, pointing to impossibility of the solution of many problems without the appeal to metaphysics.24 articles presented in this collection give a complete look about all parties of many-sided thinking of Leibniz. The collection presents some kind of encyclopedia of Leibniz’s philosophy in which all last achievements of the modern Leibniz Research are accumulated and are presented in such systematic order that the collection by right can be considered as the monography and to serve as the reference book for everyone who wants to gain a complete and competent view about Leibniz’s philosophy.
