I Edmund Husserl's Logische Untersuchungen is, by any standard and also by nearly common consent, a great philosophical work. Within the phenom enological movement, it is generally recognised that the breakthrough to pure phenomenology - not merely to eidetic phenomenology, but also to transcendental phenomenology - was first made in these investiga tions. But in the context of philosophy of logic and also of theory of know ledge in general, these investigations took decisive steps forward. Amongst their major achievements generally recognised are of course: the final death-blow to psychologism as a theory of logic in the Prolegomena, a new conception of analyticity which vastly improves upon Kant's, a theory of meaning which is many-sided in scope and widely ramified in its appli cations, a conception of pure logical grammar that eventually became epoch-making, a powerful restatement of the conception of truth in terms of 'evidence' and a theory of knowledge in terms of the dynamic movement from empty intention to graduated fulfillment. There are many other detailed arguments, counter-arguments, conceptual distinctions and phenomenolo gical descriptions which deserve the utmost attention, examination and assimilation on the part of any serious investigator. With the publication of J. N. Findlay's English translation of the Untersuchungen, it is expected that this work will find its proper place in the curriculum of the graduate programs in philosophy in the English speaking world.

The twelve original studies collected in this volume examine different aspects of Edmund Husserl's Logical Investigations. They are authored by scholars and specialists internationally recognized for their expertise in the fields of logic, phenomenology, history of philosophy and philosophy of mind. They approach Husserl's groundwork from different angles and perspectives and shed new light on a number of issues such as meaning, intentionality, ontology, logic, etc.

Edmund Husserl is the founder of phenomenology and the Logical Investigations is his most famous work. It had a decisive impact on twentieth century philosophy and is one of few works to have influenced both continental and analytic philosophy. This is the first time both volumes have been available in paperback. They include a new introduction by Dermot Moran, placing the Investigations in historical context and bringing out their contemporary philosophical importance. These editions include a new preface by Sir Michael Dummett.

Husserl's "Logical Investigations" is designed to help students and specialists work their way through Husserl's expansive text by bringing together in a single volume six self-contained, expository yet critical essays, each the work of an international expert on Husserl's thought and each devoted to a separate Logical Investigation.

This volume is a window on a period of rich and illuminating philosophical activity that has been rendered generally inaccessible by the supposed "revolution" attributed to "Analytic Philosophy" so-called. Careful exposition and critique is given to every serious alternative account of number and number relations available at the time.

Abductive Reasoning: Logical Investigations into Discovery and Explanation is a much awaited original contribution to the study of abductive reasoning, providing logical foundations and a rich sample of pertinent applications. Divided into three parts on the conceptual framework, the logical foundations, and the applications, this monograph takes the reader for a comprehensive and erudite tour through the taxonomy of abductive reasoning, via the logical workings of abductive inference ending with applications pertinent to scientific explanation, empirical progress, pragmatism and belief revision.
