The lifeworld is saturated with claims, justifications, assertions, validities, values and reasons; it is, in a manifold of senses, the very domain of right. In this brilliantly argued book, Sophie Loidolt advances the compelling thesis that these structures of right and justification, broadly construed, not only shape lived experience, but are, as ‘‘fundamentale Weisen der Welterschliesung,’’ constitutive of subjectivity itself (p. 1). Loidolt takes as her point of departure the phenomenology of Edmund Husserl and offers a detailed reconstruction of Husserl’s genetic analyses of theoretical evidence and justification found in his later writings, above all Experience and Judgment, as well as a thorough presentation of the main trends in the development of his ethical writings from 1908 to the end of his career. This project is not limited to reconstruction and interpretation of Husserl’s text, however, but has instead the goal of outlining a theory of ‘‘right thinking’’ (rechtliches Denken) on phenomenological grounds. A good part of this goal is achieved in the first part of the book, ‘‘Zur Genesis des rechtlichen Denkens bei Husserl,’’ which in turn divides into a discussion of Husserl’s conceptions of theoretical and practical reason. The second major part of the book, as the title ‘‘Horizonte von Kritik und Weiterfuhrung: Zur Genesis des rechtlichen Denkens bei Levinas und Apel’’ indicates, takes the principal results of the first part and further develops them in conjunction with a reflection on the phenomenology of alterity found in the work of Emmanuel Levinas, while also opening a dialogue with the transcendental pragmatics of Karl-Otto Apel. A key element of the theory of right that emerges from the first part is the Husserlian thesis of the pre-predicative origins of the basic sense of logical concepts such as modality, validity, and evidence (Chapter III). Modality here plays a particularly important role, and Loidolt specifically emphasizes the importance of a break with originary, passive doxa as the origin of the critical, and with that the
