In this short text, a distinguished philosopher turns his attention to one of the oldest and most fundamental philosophical problems of all: How it is that we are able to sort and classify different things as being of the same natural class? Professor Armstrong carefully sets out six major theories—ancient, modern, and contemporary—and assesses the strengths and weaknesses of each. Recognizing that there are no final victories or defeats in metaphysics, Armstrong nonetheless defends a traditional account of universals as the (...) most satisfactory theory we have.This study is written for advanced students, but as Armstrong goes considerably beyond his earlier work on this topic, it will interest professional scholars as well. Carefully plotted and clearly written, Universals is both a paradigm of exposition and a case study on the value of careful analysis of fundamental issues in philosophy. (shrink)

Jeffrey E. Brower presents and explains the hylomorphic conception of the material world developed by Thomas Aquinas, according to which material objects are composed of both matter and form. In addition to presenting and explaining Aquinas's views, Brower seeks wherever possible to bring them into dialogue with the best recent literature on related topics. Along the way, he highlights the contribution that Aquinas's views make to a host of contemporary metaphysical debates, including the nature of change, composition, material constitution, the (...) ontology of stuff vs. things, the proper analysis of ordinary objects, the truthmakers for essential vs. accidental predication, and the metaphysics of property possession.

New translations of the central mediaeval texts on the problem of universals are presented here in an affordable edition suitable for use in courses in mediaeval philosophy, history of mediaeval philosophy, and universals. Includes a concise Introduction, glossary of important terms, notes, and bibliography.

In this article I address the Problem of Universals by answering questions about what facts a solution to the Problem of Universals should explain and how the explanation should go. I argue that a solution to the Problem of Universals explains the facts the Problem of Universals is about by giving the truthmakers (as opposed to the conceptual content and the ontological commitments) of the sentences stating those facts. I argue that the sentences stating the relevant facts are those like (...) 'a has the property F', that is, sentences stating that a particular has a certain property. Finally I show how answering these questions in this way transforms the Problem of Universals, traditionally conceived as the One over Many, that is, the problem of explaining how different particulars can have the same properties, into the Many over One, that is, the problem of explaining how the same particular can have different properties. The Problem of Universals is the problem of the Many over One. (shrink)

Throughout his career Aquinas held to the Avicennian doctrine that the nature or essence of sensible substances is somehow indifferent. According to Aquinas's version of this well-known doctrine an essence as such posssesses only those characteristics which are specified in its definition. The essence of a human being, for instance, possesses as such animality and rationality and nothing else. On this view, all the other characteristics and in particular general properties like being one or many, universal or particular, do not (...) belong to essence as such, but are attributed to it only in so far as it enjoys a particular mode of existence. Essence, for instance, is in itself neither universal nor particular, but is universal in so far as it exists in the intellect and particular in its extra-mental existence in different individuals. Although Aquinas is entirely consistent all through his career in maintaining that essence as such is neither universal nor particular, there is a point of viw from which the essence of a sensible substance can be regarded as universal or common, namely the point of view of inviduation.

William of Ockham (c.1287-1347) is known to be one of the major figures of the late Middle Ages. The scope and significance of his doctrine of human thought, however, has been a controversial issue among scholars in the last decade, and this book presents a full discussion of recent developments. Claude Panaccio proposes a richly documented and entirely original reinterpretation of Ockham's theory of concepts as a coherent blend of representationalism, conceptual atomism, and non reductionist nominalism, stressing in the process (...) its special interest for current discussions in philosophy of mind and cognitive sciences.

In this study of the relationship between Boethius and Thomas Aquinas,.

Apart from his Consolation of Philosophy, perhaps the most well known text of Boethius is his discussion of universals in the Second Commentary on Porphyry’s Isagoge.1 In that passage, he first reviews the arguments for and against the existence of universal entities, and then offers a theory he attributes to Alexander of Aphrodisias, a kind of theory called in recent times “moderate realism,” according to which there are no universal entities in the ontology of the world, but nevertheless there is (...) an objective, non-arbitrary basis for the formation of our universal or general concepts about that world. At the very end of the passage, Boethius adds the intriguing comment that he has presented this view not necessarily because it is his own, but because it is the one that fits Aristotle’s.. (shrink)
