Book review focuses on the book by Günther Neumann, dedicated to the thought of Heidegger and Leibniz. The book deals with Heidegger's three approaches to Leibniz's thought: Interpretation of Leibniz in the context of the making of fundamental ontology and in Being and Time, as well as the reading of Leibniz after Being and Time; Interpretation of Leibniz during the transition to Ereignis thought; Interpetation of Leibniz in the framework of Ereignis thought. Author's scrupulous close reading approach allows to show the changes in Heidegger's approach to Leibniz's philosophy, as well as sketch out the placement of Leibniz's great themes on the horizon of Heidegger's history of the truth of being. Author also shows that from metaphysics there stems a certain view in the modern philosophical discussions oriented on neurosciences-a certain view on the human being and on the freedom of will. On this background Heidegger appears as a thinker who has looked beyond the alloy of metaphysics and sciences, in which the concept of freedom has been greatly restricted. Heidegger manages ( thanks to the radical questioning of Being) to turn the view on the problem of freedom, which appears in G. Neumann's books as the main problem of philosophy-through the contact of Leibniz's thought and Heidegger's.

In the wide and varied field of contemporary philosophy different philosophers can be found-both ones that develop their own original thoughts in close connection with philosophy's classical texts, and ones that take part in modern science's methodological and/ or conceptual discussions. If the form er are more oriented on knowing the texts and context of philosophy, then the latter focus on the constellation of various actual sciences, which poses its own ( often very partisan and one-sided) criteria as to what can be called the contribution of philosophy, in a cultural context heavily influenced by science. Rarely does anyone succeed in joining these routes ( dialogues with the classics of philosophy and with actual science ), especially in a way where philosophy's dialogue with science actually gains a new quality-illuminates whether it is «on the path ofbeing, or nonbeing" (Heidegger, 1993, 38).

Such a conjoining perspective is provided by the philosopher Günther Neumann. He has studied physics and mathematics in the University of Erlangen-Nuremberg, philosophy in the University of Freiburg, been a stipendiary of MIT in USA, clone physics research with the Fraunhofer Society and as a physicist been teachirig in various universities. Parallel to aforementioned, he is also an editorial member of the ''Heideggerian studies" and an editor of several volumes of the Complete works of Martin Heidegger, and currently a member of the Scientific board of Heidegger-Gesellschaft. This feature of his academic life's way has shown itself in publications: his books and papers deal with questions of mathematics and physics, and also with those of philosophy (modern metaphysics, philosophy of nature, phenomenology).

In correspondence, the author has emphasised that he turned his gaze especially on Heidegger's understanding of Leibniz's thought since the extensive January 2017 paper read in Ron1e's Pontifical Lateran University. The Heidegger und Leibniz volume published in 2020 serves as a prelude to Hans-Christian Günther's edited multi-volume guide to Heidegger - Das Denken Martin Heideggers. In this volume, the author focuses more on those aspects of understanding of Leibniz, that change (or stay intact) in Heidegger's thought viewed through the perspective of immanent development. In this book the author manages to excellently show the three phases of Heidegger's reception of Leibniz's thought: Reading of Leibniz in the phase of making and development of the project of fundamental ontology; Reading of Leibniz during the transition to Ereignis-Thought in the 30s; Reading of Leibniz in the framework of the History of Being (30s and onward).
As in the case of other great Western thinkers, so in Leibniz's does Heidegger try to unveil the "unsaid in what is said." After all, it is not only about the "unfathomable variety of Leibniz's positions and questions;" but also about the "thinking struggle," about starting a philosophical conversation with Leibniz - to think about what Leibniz thought as monads, as Dasein.
In this conversation-struggle of several decades it is seen that Leibniz is a philosopher through whose works and main concepts an approach to the core and basic movement of Western metaphysics is shown. The author of the book manages to show just how much Heidegger's turn to Leibniz shows a perspective on technology, information, language, freedom, nature and other fundamental keywords of philosophy. And it is not about a mere historical overview, but about the historical fate of the West, which Heidegger tried to uncover with the help of his approach of history of being, in which the transition from Leibniz to German Idealism to Nietzsche is shown (Neumann, 2020, 77).
The book by Günther Neumann is in the field of the coordinated problematics a very valuable addition not only to the research of the thought of Leibniz and Heidegger, but also a strong addition to the acknowledgement of the scope of Heidegger's thought - which is especially essential in a time where it has become far too easy to see behind every thought uttered by a thinker only a narrowly viewed "political" aspect. The editor of Heidegger Leibniz-Seminaries, and the editor of two complete volumes of Heidegger's Vorträge as apart of Heidegger's Gesamtausgabe, the connoisseur of Heidegger's thought - Neumann with his books manages to keep the level of conversation at a very high bar, where a true thought exchange with and about Heidegger may begin.
