Given his known predilection for ontological parsimony, Ockham’s ontology of artifacts is unsurprisingly reductionist: artifacts are nothing over and above their existing and appropriately ordered parts. However, the case of artifacts is notable in that they are real objects that human artisans produce by bringing about a real change: they spatially rearrange existing natural thing(s) or their parts for the sake of some end. This article argues that the human contribution to the nature and production of artifacts is two-fold: (1) (...) the artisan’s cognitive grasp of her expertise and her decision to deploy that expertise are the two efficient causes necessary to explain the existence of an artifact, and (2) the purpose that the artisan had in mind when she decided to make an artifact fixes the function(s) of the artifact such that an artisan’s purpose is the final cause necessary to explain what an artifact is. Artifacts indeed exist, owing what they are and that they are to intelligent and volitional human activity, which Ockham never denies. The article submits that a myopic focus on Ockham’s indisputable reductionism does not exhaust what is metaphysically interesting and relevant about artifacts. (shrink)

In William Ockham on Metaphysics, Jenny E. Pelletier gives an account of Ockham's concept of metaphysics as the science of being and God as it emerges sporadically throughout his philosophical and theological work.

ABSTRACT This paper reconstructs William of Ockham's (c. 1287–1347) account of the ontology of social groups. Across his writings, Ockham mentions kingdoms, religious orders, crowds, people, armies, and corporations. Using the political community as a case-study against the background of Ockham’s metaphysics of parts and wholes, it is argued that at least some social groups are identical to a plurality of many human beings who have decided to order themselves with respect to another in some particular way. In this regard, (...) a social group is a structured aggregate that is nothing over and above its existing and ordered parts, and, at least in the case of the political community, is like an artefact inasmuch as it is partly dependent on the volitional acts of its members to exist at all.

It has long been acknowledged that one of the most original aspects of Ockham’s account of knowledge is his contention that bodies of scientific knowledge are aggregates but without much explanation as to why he holds this view. In this chapter, I argue that a plausible philosophical motivation lies in the inner structure of his mental ontology, namely, in the intellect’s habits, acts, and their objects, which are the true and necessary principles and conclusions of demonstrations. Ockham upholds what I (...) call a “Principle of Object-Act-Habit-Specification,” according to which kinds of habits and their acts are determined by the objects they grasp. This principle entails that if a body of scientific knowledge contains two or more sentences, it can only have aggregate unity. Furthermore, I look at the logical and determinate orders that gather together the sentences of various aggregate bodies of scientific knowledge. (shrink)

In one of his Quodlibeta, William of Ockham entertains two concepts of God, one theological and the other philosophical. He argues that conclusions involving a theological concept of God are believable and can only be established in theology where recourse to faith is permissible. By contrast, conclusions involving a philosophical concept of God are knowable and can be proved in philosophy and theology. The source of these two concepts lies in the Sentences commentary of his confrère Walter Chatton,1 who explores (...) how different descriptions of God affect the provability of theological conclusions about God. Chatton himself is reacting to Ockham’s earlier Sentences commentary where Ockham suggests that a... (shrink)

This slim volume contains a collection of eight essays that were originally given as lectures in 2002 under the aegis of the Society for Medieval Logic and Metaphysics. It is the second in a series of nine volumes published thus far, on subjects such as mental representation, free will, the ontology of individuation, the conceivability of God, skepticism, and nominalism. The title of the present volume is slightly misleading. Only the first two contributions are devoted to medieval treatments of the (...) ten Aristotelian categories (substance, quantity, relation, quality, etc.). The remaining six are about “what is beyond.” One might assume this is intended to refer to God or to the transcendentals, i.e. being, one .. (shrink)

In this introduction, we briefly introduce the concept of social ontology, a fertile sub-field of contemporary analytic metaphysics, and present the motivation for the present volume, which is largely though not exclusively historical in scope. We explain that philosophers in the ancient, medieval, and early modern world, with an emphasis on the medieval tradition, likewise took up questions and issues that are now discussed by philosophers working in social ontology. We then present the contents of the volume and suggest further (...) lines of research. (shrink)

In this short but dense monograph, Roques sets out to fill a significant lacuna in the literature on William of Ockham's logic, epistemology, and metaphysics: his theory of real definitions. Remarkably, the subject has received little attention, given that nominal definitions, specifically in connection to complex connotative concepts in mental language and their role in Ockham's ontological reductionism, have been a central focus since the early 1980s. One reason for this oversight may be the historical association between real definitions and (...) the realist view that essences are universal entities. Ockham, a resemblance nominalist, holds that all essences are individual entities; this does not, as Roques's present... (shrink)

This book offers a collection of contributions on medieval, early modern, and contemporary perspectives on social ontology. Since the 1990s, social ontology has emerged as a vibrant research area in contemporary analytical philosophy. Questions concerning the nature and properties of social groups, institutions, facts, and objects like money and marriage, have been thoroughly discussed. However, the historical perspective has been largely neglected. One of the central aims of this volume is to show that relevant views on social ontology can be (...) found in medieval and early modern philosophy (ca. 1200-1700 C.E.), when, for example, the ontological status of money, law, and the sacraments was hotly debated. We see, furthermore, diverging positions between Aristotelian-inspired authors, who resort to a more naturalistic view of the emergence of the social realm, and authors like Olivi and Ockham, who emphasize the role of human free will and contractualist agreements. This book is the very first to address historical and contemporary social ontologies. Both historians of philosophy and philosophers will benefit from this juxtaposition, which fosters a better understanding of historical positions and approaches by using today’s conceptual and analytical tools, and allows the contemporary debate to gain new perspectives by confronting its own medieval and early modern history.

Towards the end of Aline Medeiros Ramos’s study of John Buridan on craft as an intellectual virtue, she mentions William Ockham in passing and points towards his conception of craft. In this paper, I take up her implicit invitation to explore that conception. I begin by reconstructing Ockham’s notion of craft, and then proceed to discuss three consequences of that conception: the moral neutrality of craft, the role of deliberation in craftwork, and the epistemic status of craft and the craftworker. (...) I conclude by summarizing a number of issues that Buridan, according to Medeiros Ramos, finds it important to discuss, and which are noticeably absent from Ockham’s considerations. (shrink)
