called in question, then naturally no fact, science, could be presupposed. Thus Plato was set on the path to the pure idea. Not gathered from the de facto sciences but formative of pure norms, his dialectic of pure ideas-as we say, his logic or his theory of science - was called on to make genuine 1 science possible now for the first time, to guide its practice. And precisely in fulfilling this vocation the Platonic dialectic actually helped create sciences in the pregnant sense, sciences that were consciously sustained by the idea of logical science and sought to actualize it so far as possible. Such were the strict mathematics and natural science whose further developments at higher stages are our modem sciences. But the original relationship between logic and science has undergone a remarkable reversal in modem times. The sciences made themselves independent. Without being able to satisfy completely the spirit of critical self-justification, they fashioned extremely differentiated methods, whose fruitfulness, it is true, was practically certain, but whose productivity was not clarified by ultimate insight. They fashioned these methods, not indeed with the everyday man's naivete, but still with a na!ivete of a higher level, which abandoned the appeal to the pure idea, the justifying of method by pure principles, according to ultimate a priori possibilities and necessities.

Husserl and Mathematics explains the development of Husserl's phenomenological method in the context of his engagement in modern mathematics and its foundations. Drawing on his correspondence and other written sources, Mirja Hartimo details Husserl's knowledge of a wide range of perspectives on the foundations of mathematics, including those of Hilbert, Brouwer and Weyl, as well as his awareness of the new developments in the subject during the 1930s. Hartimo examines how Husserl's philosophical views responded to these changes, and offers a pluralistic and open-ended picture of Husserl's phenomenology of mathematics. Her study shows Husserl's phenomenology to be a method capable of both shedding light on and internally criticizing scientific practices and concepts.

Originally published in French under the title La Logique de Husserl: Étude sur Logique Formelle et logique transcendentale.

Edmund Husserl (1859-1938) is widely regarded as the principal founder of phenomenology, one of the most important movements in twentieth-century philosophy. His work inspired subsequent figures such as Martin Heidegger, his most renowned pupil, as well as Jean-Paul Sartre and Maurice Merleau-Ponty, all of whom engaged with and developed his insights in significant ways. His work on fundamental problems such as intentionality, consciousness, and subjectivity continues to animate philosophical research and argument. The Husserlian Mind is an outstanding reference source to the full range of Husserl's philosophy. Forty chapters by a team of international contributors are divided into seven clear parts covering the following areas: major works phenomenological method phenomenology of consciousness epistemology ethics and social and political philosophy philosophy of science metaphysics. Contained in these sections are chapters on many of the key aspects of Husserl's thought, including intentionality, transcendental philosophy, reduction, perception, time, self and subjectivity, personhood, logic, psychology, ontology, and idealism. Offering an unparalleled guide to the enormous range of his thought, The Husserlian Mind is essential reading for students and scholars of Husserl, phenomenology, and the history of twentieth-century philosophy. It will also be of interest to those in related fields in the humanities, social sciences, and psychology and the cognitive sciences.

The Essential Husserl, the first anthology in English of Edmund Husserl's major writings, provides access to the scope of his philosophical studies, including selections from his key works: Logical Investigations, Ideas I and II, Formal and Transcendental Logic, Experience and Judgment, Cartesian Meditations, The Crisis of European Sciences and Transcendental Phenomenology, and On the Phenomenology of the Consciousness of Internal Time. The collection is an indispensable resource for anyone interested in twentieth-century philosophy.

This is a critical examination of the three types of logic advocated by current philosophical schools. Harris shows that certain basic presuppositions underlying the techniques of symbolic logic have resulted in intellectual stultification, moral dilemma, and practical sterility. These presuppositions are shown to be at variance with those of contemporary scientific method. Critical consideration is given to alternatives, and a more appropriate logic of science is proposed, providing an escape from crippling relativism and promising objective validation of value judgments. This approach offers some prospect of solutions to the major problems now troubling our civilization.
