William of Ockham, the most prestigious philosopher of the fourteenth century, was a late Scholastic thinker who is regarded as the founder of Nominalism, the school of thought that denies that universals have any reality apart from the individual things signified by the universal or general term. Ockham's Summa Logicae was intended as a basic text in philosophy, but it's originality and scope encompass his whole system of philosophy. Yet the paucity of English translations and the structural complexity of the Latin have made the Summa, until now, almost completely inaccessible. Here Michael Loux has translated the first part of the Summa, one of the most original and influential medieval texts in logic. Preceding the translation are two essys: The first focuses on Ockham's ontology; the second deals with his theory of supposition. They are meant to introduce the reader to the central themes of Part I of the Summa, but, while introductory, these essays incorporate a controversial interpretation of Ockham which is intended to suggest a continuity between his philosophy and the work of contemporary analytic philosophy.

Charles Peirce, the founder of pragmatism, was a thinker of extraordinary depth and range - he wrote on philosophy, mathematics, psychology, physics, logic, phenomenology, semiotics, religion and ethics - but his writings are difficult and fragmentary. This book provides a clear and comprehensive explanation of Peirce's thought. His philosophy is presented as a systematic response to 'nominalism', the philosophy which he most despised and which he regarded as the underpinning of the dominant philosophical worldview of his time. The book explains Peirce's challenge to nominalism as a theory of meaning and shows its implications for his views of knowledge, truth, the nature of reality, and ethics. It will be essential reading both for Peirce scholars and for those new to his work.

A major contribution to the history of philosophy in the later medieval period (1250-1350).
