Written shortly after Jaspers's major systematic work and before his analysis of the problem of truth, Reason and Existenz occupies a primary position in the development of his thought.

This book traces the work of German philosopher Karl Jaspers (1883-1969) from his origins as a young psychiatrist up to his maturity as an existentialist philosopher. The critique of Jaspers’s thought follows his attempts to grant meaning to the human search for self-understanding. It reveals the difficulties and frustrations entailed in this search. The book reveals to the reader Jaspers’s handling of these difficulties through constituting a philosophical relation toward the Being existing beyond the individual: other people, the world, and transcendence.In this book, the author conducts an ongoing dialog with existing research into Jaspers’s work, and proposes her own new reading. As well as critiquing the existing interpretations, the author uncovers the challenges Jaspers’s character has presented the readers. Unlike most scholars, who generally ignored Jaspers’s early writings, dealing with psychiatry and psychology, this book suggests a philosophical reading of these writings. This exposes the unity of the world from which Jaspers created, first as a psychiatrist and later as a philosopher. This reading shows Jaspers’s work as an ambitious attempt to formulate an original perception of the two basic themes that have interested philosophy and human thought throughout the ages: Selfhood and Being.

Karl Jaspers is one of the least understood and most neglected major philosophers of the twentieth century, and yet his ideas, particularly those concerned with death, have immense contemporary relevance.Filiz Peach provides a clear explanation of Jaspers' philosophy of existence, clarifying and reassessing the concept of death that is central to his thought. For Jaspers, a human being is not merely a physical entity but a being with a transcendent aspect and so, in some sense 'deathless'. Peach explores this transcendent aspect of humanity and what it is to be 'deathless' in Jaspersian terms.This book is a major contribution to the scarce literature on Jaspers and will be valuable to student and academic alike.
