Peter Spader has written a magisterial study on Max Scheler, one of phenomenology's earliest and greatest figures, whose theory of ethical personalism has become a major voice in the formulation of phenomenological ethics today. Spader follows Scheler's use of the classic phenomenological approach, by means of which he presented a fresh view of values, feelings, and the person, and thereby staked out a new approach in ethics. Spader recreates the logic of Scheler's quest, revealing the basis of his thought and the reasons for his dramatic changes of direction. This remarkable study provides a framework that allows us to understand Scheler's insights in the context of their dynamic evolution of his thought. It corrects imbalances in the presentation of his ideas and defends Scheler against key misunderstandings and criticisms. In short, Spader's work continues the process of developing Scheler's pioneering theory of ethical personalism.
