In the Posterior Analytics Aristotle contrasts demonstrations with syllogisms through signs. In the Prior Analytics he defines a sign as a demonstrative premise. One is thus led to ask: is a sign a demonstration? This book reconstructs the history of the notion of “demonstration through signs” from roughly the third through to the thirteenth century. It examines the work of Aristotle’s Greek, Arabic, and Latin commentators, both within and outside the tradition of the Posterior Analytics.

The Legacy of Aristotelian Enthymeme provides a historical-logical analysis of Aristotle's rhetorical syllogism, the enthymeme, through its Medieval and Renaissance interpretations. Bringing together notions of credibility and proof, an international team of scholars highlight the fierce debates around this form of argumentation during two key periods for Aristotle's beliefs. Reflecting on medieval and humanist thinkers, philosophers, poets and theologians, this volume joins up dialectical and rhetorical argumentation as key to the enthymeme's interpretation and shows how the enthymeme was the source of a major interpretive conflict. As a method for achieving the standards for proof and credibility that persist across diverse fields of study today including the law, politics, medicine and morality, this book takes in Latin and Persian interpretations of the enthymeme and casts contemporary argumentation in a new historical light.

"The Oxford Handbook of Charles S. Peirce brings together 35 essays on the American philosopher and polymath Charles Sanders Peirce (1839-1914) with the aim of showing how his work is still relevant today. The volume takes its cues from Peirce's work in phenomenology and normative philosophy-where the latter includes, besides aesthetics and ethics, also logic. Within the domain of logic, attention is given to his work in formal logic as well as his work in graphical or diagrammatic logic. Ample attention is given also to Peirce's pragmatism and his metaphysics. The volume further includes biographical papers as well as papers on abduction, semiotics, linguistics, physics, biology, religion, history, science, and education"--

A state-of-the-art overview of ancient logic for students and scholars, with in-depth analyses of its central themes.

Oxford Studies in Medieval Philosophy showcases the best scholarly research in this flourishing field. The series covers all aspects of medieval philosophy, including the Latin, Arabic, and Hebrew traditions, and runs from the end of antiquity into the Renaissance. It publishes new work by leading scholars in the field, and combines historical scholarship with philosophical acuteness. The papers will address a wide range of topics, from political philosophy to ethics, and logic to metaphysics. OSMP is an essential resource for anyone working in the area.

The history of logic and its development during the medieval period Radulphus Brito’s Quaestiones super Priora Analytica Aristotelis is a major work written in the early 1300s which treated Aristotle’s text devoted to the theory of the syllogism. Brito, perhaps one of the most influential medieval thinkers known as the Modistae, examines both categorical and hypothetical syllogisms. In his text, based on six known manuscripts which are complete or nearly complete, Brito was critical of many of the theories of his contemporary, Simon of Faversham. It should also be mentioned that Brito edited his work several times. There are at least two versions which indicate Brito returned to this material during his long career at the university in Paris. This volume is the first critical text edition of Brito’s Quaestiones super Priora Analytica Aristotelis and will therefore be of great interest to those studying the history of logic and its development during the medieval period.

Cardinal and Archbishop of Canterbury Robert Kilwardby OP (c. 1215-1279) was a very important and influential thinker in his time, but he has not received the scholarly attention that he deserves. In this book we present the first study of all of his philosophical thinking from logic and grammar to metaphysics and ethics.

This Handbook shows the links between medieval and contemporary philosophy. Topic-based essays on all areas of philosophy explore this relationship and introduce the main themes of medieval philosophy. They are preceded by the fullest chronological survey now available of the different traditions: Latin and Greek, Islamic and Jewish.

Peirce’s Speculative Grammar: Logic as Semiotics offers a comprehensive, philologically accurate, and exegetically ambitious developmental account of Peirce’s theory of speculative grammar. The book traces the evolution of Peirce’s grammatical writings from his early research on the classification of arguments in the 1860s up to the complex semiotic taxonomies elaborated in the first decade of the twentieth century. It will be of interest to academic specialists working on Peirce, the history of American philosophy and pragmatism, the philosophy of language, the history of logic, and semiotics.

In the course of the long debate on the nature and the classification of signs, from Boethius to Ockham, there are at least three lines of thought: the Stoic heritage, that influences Augustine, Abelard, Francis Bacon; the Aristotelian tradition, stemming from the commentaries on "De Interpretatione;" the discussion of the grammarians, from Priscian to the Modistae. Modern interpreters are frequently misled by the fact that the various authors regularly used the same terms. Such a homogeneous terminology, however, covers profound theoretical differences. The aim of these essays is to show that the medieval theory of signs does not represent a unique body of semiotic notions: there are diverse and frequently alternative semiotic theories. This book thus represents an attempt to encourage further research on the still unrecognized variety of the semiotic approaches offered by the medieval philosophies of language.
