Negligent omissions, cases in which an agent unintentionally forgets to fulfill an obligation, are philosophically problematic. They are problematic because they are considered blameworthy despite the fact that the conditions for voluntariness often appear unfulfilled. In an attempt to explain how they may be voluntary, this book delves into the action theories of Aristotle, Anselm, Aquinas, Scotus, and Suarez. In doing so, not only is the philosophical (and theological) importance of negligent omissions demonstrated via new and insightful interpretations, but a complex model for explaining...

In Perception and the Internal Senses Juhana Toivanen advances a detailed philosophical reconstruction of Peter of John Olivi's (ca. 1248-98) conception of the cognitive psychology of the sensitive (i.e. animal) soul. Like most medieval philosophers, Olivi thought that higher animals and human beings have many psychological capacities in common. The book analyses these capacities by concentrating on Olivi's conception of the metaphysics of the soul, his theory of perception, and his views about the post-sensory cognitive power which medieval philosophers called the internal senses....

Methods and Methodologies explores two questions about studying the Aristotelian tradition of logic. The first, addressed by the chapters on methods in the first half of the book, is directly about the medieval logical commentaries, treatises and handbooks. How did medieval authors in the different traditions, Latin and Arabic, go about their work on Aristotelian logic? In particular, how did they themselves conceive the relationship between logic and other branches of philosophy and disciplines outside philosophy? The second question is about methodologies, the subject of the chapters...

During a career spanning four decades, Sten Ebbesen has produced a body of work which stands as a remarkable and important contribution to the field of medieval philosophy. Combining philological expertise and textual work with a deep philosophical understanding and a broad historical outlook, his vast output deftly penetrates and analyses often difficult and complex issues. The present volume pays homage to this body of work by investigating topics relevant to its two most central themes: logical and linguistic analysis. True to the work it seeks to honour, these closely connected themes are...

In Ockham's Assumption of Mental Speech: Thinking in a World of Particulars, Sonja Schierbaum advances a detailed philosophical reconstruction of William Ockham's (1287-1349) conception of mental speech. Ockham's conception provides a rich account of cognition and semantics that binds together various philosophical issues and forms a point of departure for many later and even contemporary debates. The book analyses the role of mental speech for the semantics and the use of linguistic expressions as well as its function within Ockham's cognitive theory and epistemology. Carefully...

In John Duns Scotus on Parts, Wholes, and Hylomorphism, Thomas M. Ward examines Scotus's arguments for his distinctive version of hylomorphism, the view that at least some material objects are composites of matter and form. It considers Scotus's reasons for adopting hylomorphism, and his accounts of how matter and form compose a substance, how extended parts, such as the organs of an organism, compose a substance, and how other sorts of things, such as the four chemical elements (earth, air, fire, and water) and all the things in the world, fail to compose a substance. It highlights...

Richard of St.Victor (d.1173) developed original ideas about the faculty of imagination in a twelfth-century Parisian context. Related to the historical study of philosophical psychology, Richard of St. Victor's Theory of Imagination acknowledges that the faculty of imagination, being a necessary precondition for human reasoning and a link between soul and body, plays an important role in Richard's understanding of the human soul. Richard also deals with the interpretation of biblical language, metaphors, rhetoric, and the possibility of creative imagination. Considering all these...

Suarez on Aristotelian Causality offers the first comprehensive account of Francisco Suarez's position with respect to the four Aristotelian causes in his Metaphysical Disputations. Suarez deals with these causes in the greater part of Metaphysical Disputations 12-27 approximately a third of his famous work on metaphysics. Nevertheless, no previous attempt at analysis of causality as a part of his overall metaphysical position has been offered. The material, formal, efficient and final cause as understood by Suarez each receives a chapter in this volume just as his...

In The Thirteenth-Century Notion of Signification, Ana Maria Mora-Marquez presents an exhaustive study of the three 13th-century discussions explicitly dealing with the notion of Significatio. Her study aims to show that the three discussions emerge because of apparently opposite claims about the signification of words in the authoritative literature of the period, namely in Aristotle, Boethius and Priscian. It also shows that the three discussions develop in the same direction - towards a unified use of the notion of signification, which keeps its explanatory role in semiotics,...

In Walter Chatton on Future Contingents, Jon Bornholdt presents the first full-length translation, commentary, and analysis of the various attempts by Chatton (14th century C.E.) to solve the ancient problem of the status and significance of statements about the future. At issue is the danger of so-called logical determinism: if it is true now that a human will perform a given action tomorrow, is that human truly free to perform or refrain from performing that action? Bornholdt shows that Chatton constructed an original (though problematic) formal analysis that enabled him to canvass...
