William of Ockham

Aquinas, Ockham, and Burdan all claim that a person can be numerically identical over time, despite changes in size, shape, and color. How can we reconcile this with the Indiscernibility of Identicals, the principle that numerical identity implies indiscernibility across time? Almost all contemporary metaphysicians regard the Indiscernibility of Identicals as axiomatic. But I will argue that Aquinas, Ockham, and Burdan would reject it, perhaps in favor of a principle restricted to indiscernibility at a time.

Truth is a key notion in Ockham’s philosophical reductionist program, a notion that has been the object of contrasting interpretations in scholarship. My interpretation is that, for Ockham, ‘being true’ expresses an epistemological relation, namely the one through which our mind reflects on a proposition of language, compares it with an extra-mental state of affairs, and thus ascertains their correspondence. Placing truth at a point of intersection of language with mind and reality, Ockham’s interpretation of Aristotle’s characterization of philosophy as (...) the science of truth comes to be innovative. For Ockham, philosophy is a meticulous training of interpretation of language in order to account correctly for the truth-value of propositions. (shrink)

William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge involves a kind of dilemma for Ockham. Depending on how Ockham responds to this dilemma, his (...) razor will, Chatton argues, either prove unacceptably dull when it comes to determining ontological commitment or prove unacceptably sharp when it comes to determining commitments entailed by certain theological doctrines. While Chatton’s objection is subtle and interesting in its own right, the broader significance of the debate between these thinkers lies in the light it sheds on medieval approaches to issues surrounding metaphysical methodology.

William of Ockham is a towering figure in the history of philosophy and he is commonly seen as the most important nominalist thinker of the Middle Ages. His nominalism basically consists in three theses: there are no universals in the external world, no relations either, and no quantities considered as distinct entities. This book provides an introduction to Ockham's defence of these positions and to what they amount to in metaphysics, semantics, and epistemology. It thus displays the outlines of a (...) rich and carefully crafted nominalist system that is still of great philosophical interest today. All along in so doing, it situates Ockham's thought with respect to several salient contemporary debates in philosophy. (shrink)

Intellective intuitive cognition plays a key role in William of Ockham’s philosophy. On many occasions, Walter Chatton argues that this kind of cognition is unnecessary. Chatton has two main arguments for his point. First, he raises doubts about the possibility of distinguishing intellective intuitive cognition from sensory intuitive cognition. The former always arises with the latter, and whatever we can explain through the former, we can explain equally well through the latter. Second, he argues that we cannot separate the intellective (...) intuitive cognition of a singular thing from the cognition of the species of that thing. We cannot intuitively and intellectively cognize a thing without recognizing that thing as a thing of a certain kind. Chatton’s conclusion is that since we can never experience an act of intellective intuitive cognition in itself, it is superfluous to posit this act of cognition. We can explain the singular cognition of an extramental singular simply by making the cognition of its species and the sensory intuitive cognition of it interact with each other. (shrink)

We highlight the fundamental influence that the work of Alasdair Urquhart has had in the area of distributive lattice-ordered algebras and in particular to the development of Ockham algebras, to which we attach some new results.

The 16th and 17th centuries witnessed a philosophical shift that would help pave the way for modern science, a shift from metaphysical theories of material objects to other views embracing only the empirically-accessible parts of material things. One much-debated topic in the course of this shift was regarding prime matter. The late scholastic Jacobus Zabarella (1533-1589) arrived upon his views about prime matter via his version of the regressus method, a program for a sort of scientific reasoning. In his De (...) rebus naturalibus, Zabarella defends the position that prime matter is extended. However, it is less clear how he accounts for its extension. There is an important text where he apparently suggests that prime matter is extended in and of itself. However, there are two other texts apparently stating that matter is extended in virtue of a distinct accident in the category of quantity. I argue that a decisive reading based solely upon any particular texts is not available. Nevertheless, examining Zabarella’s writing on the topic as a whole, the trajectory of his overall argument is remarkably sympathetic to Averroes, who famously took the accidentally quantified position. Thus, from this systematic feature, the accidentally quantified reading is more reasonable. (shrink)

The article analyses the concept of actual infinity in William of Ockham’s thought, thanks to a close reading of his writings, first those on physics, where he argues more than once the existence of the actual infinity, intended as a set of infinite parts in act present in a continuum. By virtue of this representation of infinity, Ockham also states that two sets with infinite parts are not necessarily equal, but one of the two can be greater than the other, (...) as would happen with the revolutions of the moon and the sun in an endless time. Nonetheless, in the theological works, the Franciscan seems to have apparently a different position, since he denies the possibility of the actual infinity, either as a set of infinite entities existing all simultaneously, or as an infinite entity, since in both cases a limit would be placed on God’s omnipotence. Ockham instead demonstrates that he has a double vision of the actual infinity, similar to that of Cantor, as already proposed by Annaliese Maier. The essay will therefore show the compatibility of Ockham’s physics and theological writings by virtue of the different meanings of infinity. (shrink)

Ockham’s own formulations of his Razor state that one should only include a given entity in one’s ontology when one has either sensory evidence, demonstrative argument, or theological authority in favor of it. But how does Ockham decide which theological claims to treat as data for theory construction? Here I show how over time (perhaps in no small part due to pressure and attention from ecclesiastical censors) Ockham refined and changed the way he formulated his Razor, particularly the “authority clause” (...) that states that authoritative theological pronouncements constitute a reason for postulating entities in one’s ontology. This refinement proceeded across three stages, culminating in the political writings of the final period of his life, in which Ockham offers reasons (not previously mentioned in scholarly discussions of Ockham’s Razor) against granting ecclesial authority any significant role to play in settling ontological questions.

There is a long history of philosophers granting a privileged epistemic status to cognition of directly present objects. In this paper, I examine three important historic accounts which provide different models of this cognitive state and its connection with its objects: that of the Stoics, who are corporealists and think that ordinary perception may have an epistemically privileged status, but who seem to struggle to accommodate non-perceptual cognizance; that of Augustine, who thinks that incorporeal objects are directly present to us (...) in ‘intellectual perception’, and that, by way of contrast, ordinary sense-perception does not have a privileged epistemic status; and that of William of Ockham, who allows for unmediated action at a distance and is fairly generous about what counts as being directly present.

This paper attempts to demonstrate that the logical problematic of signification, has a very dangerous socio-political effect due to the ontological implication that is connected to the signification of terms in logic. It expounds the notion of signification in Formal Logic as exposed by William of Ockham. It thus, employs this notion of signification of terms, to discuss the term “Fulani”, to show the danger potent in distorting the signification of the term “Fulani” as in every conventional and connotative terms. (...) This work claims that as a result of the connection between logic and ontology, conceptualization and perception, names and reality, the distortion of terms, which are the building blocks of propositions in logic could lead to a dangerous cognition and perception of ontological realities. To this end, it posits a critique on the dangerous change in the signification of the term “Fulani”, in the conceptualization and perception of present day Nigeria people, of West Africa. A dangerous change, as this paper claims, if not speedily reconstructed and re-conceptualized, could lead to a disastrous situation in the socio-political reality of the Nigerian State. (shrink)

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 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: 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 the purpose that the artisan had in mind when she decided to make an artifact fixes the function 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)

This book recounts the remarkable history of efforts by significant medieval thinkers to accommodate the ontology of the Trinity within the framework of Aristotelian logic and ontology. These efforts were remarkable because they pushed creatively beyond the boundaries of existing thought while trying to strike a balance between the Church's traditional teachings and theoretical rigor in a context of institutional politics. In some cases, good theology, good philosophy, and good politics turned out to be three different things. The principal thinkers (...) discussed are Augustine, Boethius, Abélard, Gilbert of Poitiers, Bonaventure, Aquinas, Scotus, and Ockham. The aspects of Trinitarian doctrine dealt with are primarily internal ontological questions about the Trinity. The approach draws on history of theology and philosophy, as well as on the modern formal disciplines of set-theoretic semantics and formal ontology. Augustine inaugurated the project of constructing models of the Trinity in language drawn from Platonic and Aristotelian philosophy, especially the conceptual framework of Aristotle's Categories. He used the Aristotelian notions of substance and relation to set up a model whose aim was not so much to demystify the Trinity as to demonstrate the logical consistency of maintaining that there is one and only one God at the same time as maintaining that there are three distinct persons, each of whom is God. Standing against this tradition are various heretical accounts of the Trinity. The book also analyzes these traditions, using the same techniques. All these accounts of the Trinity are evaluated relative to the three constraints under which they were formed, bearing in mind that the constraints on philosophical theorizing are not limited to internal consistency but also take note of explanatory power. Besides analyzing and evaluating individual accounts of the Trinity, the book provides a novel framework within which different theories can be compared. (shrink)

One version of moral error theory maintains that the central problem with morality is an ontological commitment to irreducible normativity. This paper argues that this version of error theory ultimately depends on an appeal to Ockham’s Razor, and that Ockham’s Razor should not be applied to irreducible normativity. This is because the appeal to Ockham’s Razor always contains an intractable element of epistemic circularity; and if this circularity is not vicious, we can construct a sound argument for the existence of (...) irreducibly normative truths that contains a similar kind of epistemic circularity. This argument is a version of Pascal’s Wager which I call “Parfit’s Wager,” because it is based on a passage from Derek Parfit’s On What Matters. It states that, if we believe that there are some irreducibly normative truths, we are more likely to be believing what we ought to believe compared to not believing that there are such truths, and that this indicates that we ought rationally to believe that there are such truths, justifying the ontological commitment to irreducible normativity in the process.

In the most recent monograph on William of Ockham’s political writings, Takashi Shogimen rightly asserts that “there is no such thing as the ‘standard’ view of the Venerabilis Inceptor as a political thinker.”1 This could be said of many medieval writers, but the extent to which it is true of Ockham is noteworthy. Who else has been described as both “a constitutional liberal” and “an anarchist?”2 Was he a “meticulous deconstructor of church and polity” who “irredeemably undermined the foundations of (...) institutions” or “a true theologian” caught up in a “political and doctrinal hurricane?”3 As Tierney notes, we are “not dealing with a schizophrenic,” so it is impossible for these diverse categorizations of Ockham’s...

Review of William of Ockham, Questions on Virtue, Goodness, and the Will, ed. and tr. Eric W. Hagedorn (Cambridge University Press, 2021), in Metascience (2021.

This paper addresses the question whether future contingents are knowable, that is, whether one can know that things will go a certain way even though it is possible that things will not go that way. First I will consider a long-established view that implies a negative answer, and draw attention to some endemic problems that affect its credibility. Then I will sketch an alternative line of thought that prompts a positive answer: future contingents are knowable, although our epistemic access of (...) them is limited in some important respects.

Resumen El concepto de scientia plasmado en la obra de Guillermo de Ockham considera, en primer lugar, la teoría de la suposición, la cual transforma la visión del conocimiento evidente a partir del examen de términos y proposiciones como signos de las cosas. En segundo lugar, el conocimiento intuitivo de los singulares, el cual posibilita la formulación de proposiciones necesarias que describen hechos y estados de cosas. En tercer lugar, una perspectiva lógica de scientia como conjuntos de proposiciones que configuran (...) las distintas ciencias.The concept of scientia established in William of Ockham's work considers firstly, the theory of supposition, which transforms the view of the evident knowledge based on the analysis of terms and propositions as signs of things. Secondly, the intuitive knowledge of singulars, which allows the formulation of necessary propositions that describe facts and state of affairs. Thirdly, a logical approach of science as set of propositions that configure the different sciences. (shrink)

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)

William of Ockham (d. 1347) was among the most influential and the most notorious thinkers of the late Middle Ages. In the twenty-seven questions translated in this volume, most never before published in English, he considers a host of theological and philosophical issues, including the nature of virtue and vice, the relationship between the intellect and the will, the scope of human freedom, the possibility of God's creating a better world, the role of love and hatred in practical reasoning, whether (...) God could command someone to do wrong, and more. In answering these questions, Ockham critically engages with the ethical thought of such predecessors as Aristotle, Augustine, Thomas Aquinas, and John Duns Scotus. Students and scholars of both philosophy and historical theology will appreciate the accessible translations and ample explanatory notes on the text. Eric W. Hagedorn is Associate Professor of Philosophy at St. Norbert College, Wisconsin. He has published a number of articles and book reviews on medieval philosophy of mind, language, and logic in journals including Oxford Studies in Medieval Philosophy and Notre Dame Philosophical Reviews.

The methods of intellectual history have not yet been applied to studying the invention of technology for printing texts and images ca. 1375–ca. 1450. One of the several conceptual developments in this period refl ecting the possibility of mechanical replication is a view of the relationship of eternity to durational time based on Gregory of Nyssa’s philosophy of time and William of Ockham’s. Th e article considers how changes in these ideas helped enable the conceptual possibilities of the dissemination of (...) ideas. It describes a direct connection of human perceptual knowledge to divine knowledge that enhanced the authority of printed production to transfer and reproduce the true and the good. (shrink)

Claude Lafleur et Joanne Carrier Suivant l’ordre traditionnel à son époque d’un cours sur la « Vieille Logique », ou Ars Vetus, Ockham, après avoir commenté l’Isagoge de Porphyre et les Catégories d’Aristote, en vient à son Expositio in librum Perihermenias Aristotelis, dont on offre ici une traduction française et une édition orthographique de la partie considérée alors comme le Proême, une partie divisée elle-même en trois parties — l’exégèse du Vénérable incepteur insistant très fortement sur le début de la (...) deuxième partie et, de façon notable, encore plus spécialement sur ce que signifie une « passion de l’âme », autrement dit, pour Ockham lui-même et surtout pour nous, un « concept ».

Following the traditional order in his time of a course on “Old Logic”, or Ars Vetus, Ockham, after commenting on Porphyry’s Isagoge and Aristotle’s Categories, comes to his Expositio in librum Perihermenias Aristotelis, of which is offered here a French translation and an orthographic edition of the part considered then as the Proem (chapter 1 of Bekker’s edition, 16a1-18, for us famous because of the “semiotic triangle” of the written, vocal and mental signs, in relation, taking into account the realities (...) [pragmata, res], with truth and falseness), a part itself divided in three parts (Bekker 16a1-2, 3-9, 9-16) — the exegesis of the Venerable Inceptor insisting very strongly on the beginning of the second part (16a3-4, thus on two lines) and, notably, even more especially on what a “passion of the soul” means, in other words, for Ockham himself and particularly for us, a “concept” (a remarkable exegesis whose structure and reprise are also considered).

Claude Lafleur et Joanne Carrier En tant qu’introduction générale aux commentaires d’Ockham sur la logique, celle de Porphyre et d’Aristote, l’Expositionis in libros artis logice Prohemium traite la nature de cette discipline, de son sujet, de son utilité, de sa spécificité et de son statut épistémologique. La nouvelle traduction française ici offerte est accompagnée d’une édition annotée qui restitue l’orthographe médiévale du latin d’Ockham.

Les Questiones in libros Phisicorum Aristotelis, putativement discutées en public au Studium franciscain de Londres par Ockham avant son départ d’Angleterre pour Avignon au printemps 1324, s’ouvrent par sept questions sur la nature du concept.

The Questiones in Libros Phisicorum Aristotelis (Questions on the books of Aristotle’s Physics), putatively discussed in public at the Franciscan Studium of London by Ockham before leaving England for Avignon in the spring of 1324, opens with seven questions about the nature of the concept. Here are offered a French translation and an orthographic edition, with an intertextual correspondence table, of this De conceptu, which, massively, appears to have been “magistrally” compiled from the excursus of the Expositio in Prohemium libri (...) Peryermenias Aristotelis, also translated and edited in this way, above, in this dossier. (shrink)

As a general introduction to Ockham’s commentaries on logic, that of Porphyry and Aristotle, the Expositionis in libros artis logice Prohemium deals with the nature of this discipline, its subject, its utility, its specificity, and of its epistemological status. The new French translation offered here is accompanied by an annotated edition that reproduces the medieval spelling of Ockham’s Latin. The same goes for the new translation of the beginning of Ockham’s first logical commentary, the Expositio in librum Porphirii De predicabilibus, (...) whose highlight is the interpretation of Porphyry’s questions on universals (genera and species).

Thomas Aquinas, John Duns Scotus, and William of Ockham disagree over how and whether virtues are specified by their objects. For Thomas, habits and acts are specified by their formal objects. For instance, the object of theft is something that belongs to someone else, and more particularly theft is distinct from robbery because theft is the open taking of another’s good, whereas robbery is open and violent. A habit such as a virtue or a vice shares or takes the act’s (...) object. For Scotus, although the same virtue or act cannot have objects which differ formally, different virtues and acts can have an object which is identical according to its formal ratio, in the way that the different theological virtues might even formally have God as their object. Ockham accepts Scotus’s view that charity and hope are two kinds of love, we will see how, unlike Scotus, he argues that these theological virtues differ on account of their immediate complex objects. The disagreement between these three figures raises important difficulties concerning what it even means to be a formal object. (shrink)

Claude Panaccio Guillaume d’Ockham rejette l’existence des universaux, des relations et des quantités à titre d’entités distinctes, mais il reconnaît en même temps que la vérité des énoncés généraux, des énoncés relationnels et des énoncés quantitatifs dépend pour l’essentiel de ce qui se passe objectivement dans le monde. On montre ici comment l’idée ockhamiste de chose résout cette tension apparente et l’on reconstruit à partir de là le programme nominaliste qui est celui d’Ockham : établir l’ontologie la plus économique possible (...) et la défendre par une théorie sémantique appropriée.

Ockham developed two theories to explain the intentionality of memory: one theory that takes previously perceived things to be the objects of memory, and another that takes one’s own earlier acts of perceiving to be the objects of memory. This paper examines both theories, paying particular attention to the reasons that motivated Ockham to give up the first theory in favor of the second. It argues that the second theory is to be understood as a theory of double intentionality. At (...) the core of this theory is the thesis that one directly remembers one’s own acts, and indirectly also the objects of these acts. The paper analyzes the cognitive mechanism that makes this double intentionality possible and examines the causal account that Ockham gave for explaining the emergence of acts of remembering. It emphasizes that he accepted nothing more than a causal chain of acts and habits, thereby offering an ontologically parsimonious theory of memory. (shrink)

In this essay, we reconsider two themes particularly discussed by the interpreters of Ockham: that of divine omnipotence and the hypothesis of the intuitive cognition of non-existent things. The purpose is to show that the hypothetical case considered by Ockham was subjected to opposite interpretations. For theological reasons, Ockham attributes not only to God but also to human beings the possibility of having acts of intuitive cognition of things that do not exist; nonetheless, he holds that it is contradictory for (...) God to give us the evident cognition of things that appear to be present when they are actually absent. Walter Chatton opposes this conclusion, arguing that no contradiction ensues from that hypothesis. Instead, he believes that it is impossible for God to give us the intuition of things that absolutely do not exist or are in no way present to us. Ockham’s arguments include some difficulties that Chatton acutely sees and discusses. In particular, Chatton calls into question Ockham’s missed distinction between the existence and the presence of the intuited thing. (shrink)

This article investigates the relation between the will and evil in Ockham’s thought. The main purpose is to show to what extent the deliberate and conscious will of evil (velle malum sub ratione mali) is possible according to Ockham’s psychological and metaethical assumptions.

Il volume ripercorre lo sviluppo del pensiero del giovane Nicola Cusano dalla frequentazione del maestro albertista Eimerico da Campo presso l’Università di Colonia (1425) e dal confronto con le posizioni filosofiche dei domenicani dello Studium coloniense, fino agli anni della maturità a Roma (1450). Il saggio illustra il contesto storico-culturale della genesi del De docta ignorantia, testo che suggella la presa di distanza di Cusano dal proprio passato universitario ma anche, al contempo, la sua insoddisfazione nei confronti dell’umanesimo diffuso in (...) Italia negli anni del Concilio di Ferrara-Firenze; e lo segue nella sua ‘caccia della Sapienza’, nell’incontro con differenti tradizioni e contesti, fino alla formulazione dell’ideale del ‘Socrate cristiano’ nell’Idiota. Il volume, riccamente documentato anche sul piano della storia delle interpretazioni e degli studi su Cusano, contribuisce a far luce sulla formazione del suo pensiero e sulle questioni che ne hanno segnato la vita.

ABSTRACTIn the recent secondary literature on Ockham’s philosophy of mind, it has been debated whether Ockham proposed an externalist or an internalist view of the intentional contents of intuitive...

In his Bipartitum in morali philosophia, the Scottish philosopher William of Manderston, a pupil of John Mair, and an Ockhamist philosopher, is quoting a text of Antonin of Padua who distinguishes the factum opened to a juridical qualification from the inner belief, known by God alone. Quoting the same text, the authors of the Malleus maleficarum try hard to distinguish three distinct fields, the inner beliefs which belongs to God, the exterior acts, the facts, which are relevant for the judges, (...) and the third field, which establishes a relation between the fact and the beliefs. This third field is proper to the inquisitors. Against this ethics of imputability, Manderston, relying on Ockham’s ethics, advocates an intentionalist ethics which depends on a sharp separation between interiority and exteriority. The soteriological dimension of the question entirely belongs to the inner life, whereas the exteriority is strictly disciplinary. By his radicality, Manderston appears as a paradigm of the modern dichotomy between conscience and law, Paolo Prodi once pointed out as a cornerstone of the religious modernity. (shrink)

Cuando G. K. Chesterton en su corto ensayo Aproximación al tomismo quiere resumir los descarríos o los logros de los sabios sobre la realidad, muestra las tres controversias generales del pensamiento: (1) la disolución de las cosas en las soluciones químicas del escepticismo, que es la controversia entre el flujo o la transición informe; (2) la difícil clasificación de las unidades ideales, que es la controversia entre realismo y nominalismo; y (3) el reconocimiento, también arduo, de la variedad cuando a (...) la vez se admite la unidad, que es el viejo acertijo metafísico de la unidad y lo múltiple. Este libro se concentra en la segunda controversia, sin el olvido de los otros dos problemas, en la persona de Guillermo de Ockham, el lógico sagaz que vivió entre los siglos XIII y XIV d.C. Las relaciones de la Literatura con la Filosofía o con la ciencia no se acaban en la especulación poética o estética de motivos filosóficos, mucho más que esto, se extienden a la práctica o ejercicio de los conceptos filosóficos. Erguido en este principio, he rescatado a la figura de Guillermo de Ockham, así como al debate por la realidad o no de las Ideas, en composiciones literarias de Carlos Fuentes, Jorge Luis Borges, Umberto Eco, el ya mencionado G. K. Chesterton, y más. (shrink)
