This paper deals with Bonaventure’s stand on the separability of accidents discussed within the framework of the theology of the Eucharist, in his Commentarium in Sententias, IV, d. 12, p. 1, a. 1, q. 1. Since an accident was traditionally defined as ens in alio, the existence of accidents apart from any subject in the Eucharist was considered philosophically challenging. The Franciscan theologian has been credited with having distinguished, for the first time (Bakker PJJM. La raison et le miracle: les (...) doctrines eucharistiques (c. 1250 – c.1400): contribution à l’étude des rapports entre philosophie et théologie. s.n., Nijmegen, 1999; Vijgen J.

München: Akademie Verlag, 2013), between the relation of accident to subject secundum aptitudinem, and the relation of accident to subject secundum actum, while sustaining that only the relation to subject secundum aptitudinem constitutes the accident’s proper definition, a view that Aquinas would subscribe to and develop further, relying on Avicenna’s idea of the real distinction between essence and existence. The chapter will discuss Bonaventure’s rather different reasons for refusing to accept actual being in alio as the accident’s essence. Bonaventure does not appeal to a distinction between being and essence but draws on the common essence of accidents in individualized substances vs. accidents as universals, or accidents secundum species sive differentias speciales.

Medieval scholastics share a commitment to a substance-accident ontology and to an analysis of efficient causation in which agents act in virtue of their powers. Given these commitments, it seems ready-made which entities are the agents or powers: substances are agents and their accidents powers. William of Ockham, however, offers a rather different analysis concerning material substances and their essential powers, which this article explores. The article first examines Ockham’s account of propria and his reasons for claiming that a material (...) substance is essentially powerful sine accidentibus. However, the article subsequently argues that, given Ockham’s reductionism about material substance, only substantial forms – never substances – are truly agents and powers. Thus, a material substance is essentially powerful but only by courtesy – per accidens, as Ockham calls it – because it has a non-identical part, its substantial form, which does all the causal work by itself, per se.

Die Studie stellt einen direkten Vergleich zwischen der Scholastik und der byzantinischen Philosophie und Theologie dar. Sie stellt Lehren der Philosophie und Theologie des Hoch- und Spätmittelalters einander gegenüber und bespricht diese in kritischer, jedenfalls nicht in doxographischer Hinsicht. Die Zeitlogik hat ihren Ursprung in der Antike. In der Spätantike und insbesondere im Mittelalter erlangten ihre Resultate auch eine theologische und politische Brisanz. Das Studium der Semantik von Sätzen über Zukunftsereignisse, die eintreten oder auch ausbleiben können, sowie das Studium der (...) Semantik von Sätzen über Vergangenheitsereignisse lehren uns Einiges über Zukunftserwartungen. Zusätzlich ist der Vergleich lateinischer und griechischer mittelalterlicher Quellen zur Zeitlogik bezeichnend für die Reichweite der philosophischen Reflektion in der mittelalterlichen Weltanschauung.

Among medieval Aristotelians, William of Ockham defends a minimalist account of artifacts, assigning to statues and houses and beds a unity that is merely spatial or locational rather than metaphysical. Thus, in contrast to his predecessors, Thomas Aquinas and Duns Scotus, he denies that artifacts become such by means of an advening ‘artificial form’ or ‘form of the whole’ or any change that might tempt us to say that we are dealing with a new thing (res). Rather, he understands artifacts (...) as per accidens composites of parts that differ, but not so much that only divine power could unite them, as in the matter and form of a proper substance. For Ockham, artifacts are essentially rearrangements, via human agency, of already existing things, like the clay shaped by a sculptor into a statue or the stick and bristles and string one might fashion into a broom. Ockham does not think that a new thing is thereby created, although his emphasis on the contribution of human artisans seems to leave questions about the ontological status of their agency open. In any case, there are no such things as natural statues, any more than substances created by human artifice. (shrink)

In In V Metaphysics, lec. 9, Aquinas distinguishes between “being by accident” (ens per accidens) and “being by itself” (ens per se) and includes the nine accidental categories under the latter. But isn’t substance a being per se while accidents are, by definition, accidental beings? Several authors—including Ralph McInerny, Paul Symington, and Greg Doolan—have offered explanations of this strange classification. Drawing on an overlooked parallel text in the Posterior Analytics commentary and on Aquinas’s critique of Avicenna’s understanding of accidental (...) denominatives, this paper presents an alternative explanation of the lecture. In the process, it clarifies how Aquinas views the relation of the ten categories to predication and suggests important implications for how we should understand the analogy of being and the phrase “substantial being” (esse substantiale).

_ Source: _Volume 53, Issue 2-4, pp 142 - 169 I offer an explanation of why the fallacy of “accident” is so called. By ‘accident’ here, Aristotle does not mean accidental predication but being _per accidens_. Understood in this way, the fallacy of accident can be analyzed in terms of the rules that Aristotle gives for being _per accidens_. The fallacy of accident lost the original justification for its name in the late Greek period. It became associated with accidental predication (...) and not with being _per accidens_. The fallacy was then solved by construing it syllogistically so that the paralogisms became invalid through not having a universal major premise. This medieval analysis became the dominant approach in the medieval period but has led to confusion over the fallacy of accident in millennia of logic books. I end by considering how to formulate the fallacy of accident more fruitfully in modern terms via Aristotle’s original approach. (shrink)

For Aristotle the fallacy of accident arises from mistakes about being per accidens and not from accidental predication. Mistakes in perceiving per accidens come from our judgements about being per accidens and so commit that fallacy. Practical syllogisms have the same formal structure as being and perceiving per accidens . Moreover perceiving per accidens typically provides the minor premise for the practical syllogism as it makes it possible for us to know singular propositions, especially those (...) about substances. Thus these minor premises may come about through fallacious reasoning, what today would be called reasoning via collateral information. On account of these foundations for the practical syllogism, even a person of practical wisdom will need a lot of luck to avoid mistakes. (shrink)

This article studies the advances made in the logic of Renaissance physiognomy from the state of the subject in antiquity and the Middle Ages. The properties and accidents of the human body are investigated in the context of the signs selected by physiognomers, whether univocal or in syndromes, strong or weak in character, negative or positive, consistent with each other or contradictory. When these signs are translated into propositions, the construction of argument which flows from them is shown to ut (...) plurimum reasoning, in which an element of quasi-mathematical proto-probability and hermeneutical thinking may be detected. These allow the question "is x more likely to be the case than y or z?" to be answered through a variety of procedures. Renaissance physiognomy is shown to be a discipline in which a novel combination of rational procedures come together, and a site of conceptual change in respect of property and accidence. (shrink)

in a january 1642 letter, rené descartes advises his correspondent—his then-follower, the Utrecht medical professor Henricus Regius—to consistently endorse the view that the human mind is related to its body by means of a "substantial union": Whenever the occasion arises, as much privately as publicly, you ought to profess that you believe a human to be a true ens per se and not per accidens and the mind to be really and substantially united to the body not through position (...) or disposition [situm aut dispositionem], as you say in your last written text, but through a true mode of union [verum modum unionis], as everyone...

In lieu of an abstract, here is a brief excerpt of the content:Cartesian CompositesPaul HoffmanTowards the end of a paper in which I argued that Descartes thinks a human being is a genuine unity, I invited other commentators to come to Descartes’s defense by accounting for his apparently contradictory claims that a human being is an ens per se and that it is an ens per accidens.1 These claims seem to be contradictory, because in saying that a human being (...) is an ens per se, Descartes appears to be asserting that a human being is genuinely one, and in saying that a human being is an ens per accidens, he appears to assert that a human being is not genuinely one, but instead is a mere heap or aggregate. In the ensuing eleven years no one has taken up my invitation, except to argue that I was mistaken in claiming that Descartes thinks a human being has per se unity in any robust sense.2In this paper I will take up the challenge myself, having noticed a similarity between Descartes’s account of the unity of composite substances and his account of composite figures having true and immutable natures. After showing how he can consistently maintain that a human being is both an ens per se and ens per accidens in roughly the same way he can consistently maintain that composite figures both do and do not have true and immutable natures, I will try to respond to criticisms of my claim that he thinks of a human being as a substance or an ens per se.Let me begin with an analysis and comparison of two passages from the Objections and Replies. In the first, from the Replies to the First Objections, Descartes [End Page 251] discusses composite figures. In the second, from the Replies to the Fourth Objections, Descartes discusses composite substances.Next, to remove the other part of the difficulty, it should be noted that those ideas which do not contain true and immutable natures, but contain only ones which are fictitious and composed by the intellect, can be divided by the same intellect, not only through abstraction, but through a clear and distinct operation, so that any ideas which the intellect cannot so divide were undoubtedly not composed by it. As, for example, when I think of a winged horse, or an actually existing lion, or a triangle inscribed in a square, I easily understand that I can also in opposition think of a horse without wings, a non-existing lion, a triangle without a square, and so on; from which it follows that these do not have true and immutable natures. But if I think of a triangle or a square (I do not speak here of a lion or horse because their natures are not clearly evident to us), then certainly whatever I apprehend as contained in the idea of a triangle, as that its three angles are equal to two right angles, etc., I will truly affirm of the triangle, and of the square whatever is found in the idea of the square. For even if I can understand a triangle, abstracting from the fact that its angles should equal two right angles, I cannot nevertheless deny that of it by a clear and distinct operation, that is, correctly understanding this is what I say. Furthermore, if I consider a triangle inscribed in a square, not in order to attribute to the square those things which pertain only to the triangle or to the triangle those things which pertain to the square, but in order to examine only those things which arise from the conjunction of the two, then its nature will be no less true and immutable than the square or triangle alone, and it will be permitted to affirm that the square is not less than twice the triangle inscribed in it and similar things which pertain to the nature of this composite figure. (AT VII 117–8; CSM II 83–4)3I am not unaware that some substances are commonly called ‘incomplete.’ But if they are said to be incomplete because they cannot exist per se alone, I confess that it seems contradictory to me that...

This book explores noteworthy approaches to modal syllogistic adopted by medieval logicians including Abélard, Albert the Great, Avicenna, Averröes, Jean Buridan, Richard Campsall, Robert Kilwardby, and William of Ockham. The book situates these approaches in relation to Aristotle's discussion in the Prior and Posterior Analytics, and other parts of the Organon, but also in relation to the thought of Alexander of Aphrodisias and Boethius on the one hand, and to modern interpretations of the modal syllogistic on the other. Problems explored (...) include: Aristotle's doctrine of modal conversion, the pure and mixed necessity-moods, modal ecthesis, the pure and mixed contingency-moods, and Aristotle's use of counter-examples. Medieval logicians brought various concepts to bear on these problems, including the distinction between per se and per accidens terms, the notion of essential predication, the distinction between ut nunc and simpliciter propositions, the distinction between de dicto and de re modals, and the notion of ampliation. All these are examined in this book. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 38.1 (2000) 27-40 [Access article in PDF] Sensible Qualities: The Case of Sound Robert Pasnau University of Colorado 1. Background The Aristotelian tradition distinguishes the familiar five external senses from the less familiar internal senses. Aristotle himself did not in fact use this terminology of 'external' and 'internal,' but the division became common in the work of Arab and Hebrew philosophers, and in (...) the Latin West the distinction is taken for granted.1 I am going to put to one side the obscurities involved in the various internal senses of phantasia, imagination, memory, etc.; I will instead focus on the external senses. These five external senses—sight, hearing, smell, taste, touch—have their familiar counterparts in the external world: color, sound, odor, flavor, and the various tangible qualities. (The tangible qualities, unfortunately, resist being reduced to a single genus, and are typically listed as hot and cold, wet and dry, etc., where this etc. stands in for the complete list that one might or might not be able to give.2 ) These sensibilia (I will simply speak of sensibles) were known as the proper or special objects of the external senses.In addition to these proper objects, the senses were taken to have five common objects—size, shape, number, motion, rest—and also an unlimited variety of incidental objects, the per accidens sensibles—Coriscus, one's enemy, a horse race, etc. These per accidens sensibles are in a way the most interesting and important sense objects of all. They are interesting, first, inasmuch as one of the hardest and most interesting problems about perception is the problem of seeing as, which seems to be precisely the phenomenon at issue [End Page 27] here. They are important, also, inasmuch as genuine perception, as we now think of it, almost always involves the perception of something sensible per accidens. Our everyday sensory experiences revolve around the experience of seeing objects of certain kinds. We can of course step back and decide that what we are really seeing is colors and shapes. But that is not how we ordinarily see things.Despite their interest and importance, I want to put aside these per accidens sensibles, and focus instead on the common and proper sensibles, both of which Aristotle described as sensible per se (kath' hauta). In his classic statement on the objects of sensation, at De anima II 6, 418a7-25, Aristotle suggests that the grounds for distinguishing the per se from the per accidens are that the former sensibles are capable in their own right of making an impression on the senses. Color itself affects the external senses, and so does size. Coriscus, however, considered as Coriscus, does no such thing. He affects the senses only inasmuch as he is colored, perfumed, etc.3 To focus on the per se sensibles, then, is to focus on those things in the world that are suited to make impressions on the external senses.Why are some such sensibles proper, whereas others are common? The well-known rule of thumb here, reflected in how we refer to these sensibles, is that each proper sensible can be perceived by only one of the external senses. The common sensibles are those per se sensibles that fail this test. (Note that, of the common sensibles, only number, movement and rest are truly common to all five of the senses; shape and size are perceptible only by touch and sight.4 ) It is not clear, however, that this is the appropriate criterion for distinguishing the proper from the common sensibles. Albert the Great, for instance, argues that a proper sensible must meet three tests: (1) It is sensed by only one sense; (2) this sense is not capable of error with respect to it; and (3) the organ of this sense is naturally suited to be affected by it alone.5 The last of these tests is problematic, however, for at least two reasons. First, it is problematic for touch, given that the tangible qualities resist being reduced to a single genus. Second, more seriously... (shrink)

Prima facie it seems easy to understand what he had in mind when he spoke of accidental being and being as true. Accidental or incidental being, what the Latins would later call ens per accidens, was in fact a juxtaposition of two or more categorical beings. As such it lacked a unified essence and thus it lacked genuine being. It was being "only in name." Being as true, he told us, was in the synthesis of the intellect, that is, (...) the intellect's second operation of judgment. Apparently, it was the being of the copula "is" in a true judgment. Contrasted with this was being as false, or pseudo-being, which strictly is nonbeing, found in the copula of a false judgment. (shrink)

Truth of x (independently of any description of x) that it is f. A property f which holds of x but is not per se of x is said to hold per accidens of x. The essence of an individual is the sum of its per se properties. We can formulate the following: doctrine a: concrete individuals do not have essences though abstract entities do. Doctrine b: concrete individuals have essences but they do not individuate, whereas abstract entities have (...) essences which do individuate. Assumption i: we shall say that a thing exists insofar as it has an essence. Assumption ii: we shall say that we know a thing when we know what its per se properties are. We argue that plato held doctrine a and aristotle doctrine b (with assumptions i and ii). (edited). (shrink)

The article looks into the recent magisterium of the Church on the death penalty and deems it an instance of the development of doctrine rather than a circumstantiated reaction. It then dwells on the thinking that constitutes the backbone of the Encyclical Evangelium Vitae and compares and contrasts it with the various pronouncements of the teaching office of the Church, and with the two editions of the Cathechism of the Catholic Church. When one carefully examines the issue, human dignity and (...) its consequent human rights - among which one must mention the inalienable right to life - emerge as the hermeneutical cog of the problem. Together with the personalistic views of Vatican II, such a hermeneutic asks for a rethinking of the ethical norms in penal law which, in a clearer and more definitive way - per se, and not simply per accidens -, must then declare the moral implausibility of death whenever it is meted out as punishment. A death inflicted on someone else can only be justified within the strict and rigorous condition of legitimate self-defence. (shrink)

At the opening of Spinoza’s Ethics, we find the three celebrated definitions of substance, attribute, and God: E1d3: By substance I understand what is in itself and is conceived through itself, i.e., that whose concept does not require the concept of another thing, from which it must be formed [Per substantiam intelligo id quod in se est et per se concipitur; hoc est id cujus conceptus non indiget conceptu alterius rei, a quo formari debeat]. E1d4: By attribute I understand what (...) the intellect perceives of a substance, as constituting its essence [Per attributum intelligo id, quod intellectus de substantia percipit, tanquam ejusdem essentiam constituens]. E1d6: By God I understand a being absolutely infinite, that is, a substance consisting of an infinity of attributes, of which each one expresses an eternal and infinite essence We are accustomed to think of these paramount definitions as a fixed and settled formulation of the core of Spinoza’s metaphysics, but if we look at the development of Spinoza’s thought, the picture we get is quite different. In the early drafts of the Ethics and in his early works, Spinoza seems to have experimented with various conceptualizations of the relations between substance, attribute, and God. Some of Spinoza’s works make barely any use of the notions of substance and attribute, and the testimony of Spinoza’s letters suggests that, at a certain stage in his philosophical development, the concept of attribute may have been put on the back burner, if not completely dropped. Indeed, another closely related concept—accident [accidens]—was fated to be pulled out of the system (and for good reasons ). The final version of the Ethics makes hardly any use of this notion, but Spinoza’s letters show that in early drafts of the Ethics he used the term ‘accident’ to refer to what cannot be or be conceived without substance. In this paper I will attempt to provide a brief outline of the genealogy of Spinoza’s key metaphysical concepts. This genealogy, like any other, can help us to reexamine and reconsider what seems to us natural, stable and obvious. In the first part of the paper, I rely on Spinoza’s letters to trace the development of his definitions of substance and attribute in the early drafts of the Ethics. The letters, whose dates are more or less established, also provide a temporal grid for our subsequent discussions. The second part surveys Spinoza’s discussion and conceptualization of substance and attributes in the Treatise on the Emendation of the Intellect, the Theological-Political Treatise (1670), and briefly, Spinoza’s 1663 book on Descartes’ Principles of Philosophy, and its appendix on Metaphysical Thoughts, the Cogitata Metaphysica. The third part of the paper is dedicated to Spinoza’s understanding of substance and attribute in the Short Treatise on God, Man, and His Well-Being. I conclude with some remarks on the stability of Spinoza’s final position on the issue, as expressed in the published version of the Ethics . (shrink)

The present essay takes up matters discussed by Robert Pasnau in his response to our previous criticism of his account of Aquinas's view of when a foetus acquires a human soul.

We contend that in his criticisms of our account Pasnau fails clearly to (...) distinguish first, between a passive potentiality and an active capacity; second, between having a power intrinsically and being an instrumental agent of that which has it intrinsically; third, between per accidens and per se causal series; and fourth, between sense cognition and conceptual thought. We conclude that philosophy and embryology support the position that human beings exist from the point of conception. (shrink)

In this article I argue for an empiricist view on laws. Some laws are fundamental in the sense that they are the result of inductive generalisations of observed regularities and at the same time in their formulation contain a new theoretical predicate. The inductive generalisations simul- taneously function as implicit definitions of these new predicates. Other laws are either explicit definitions or consequences of other previously established laws. I discuss the laws of classical mechanics, relativity theory and electromagnetism in detail. (...) Laws are necessary, whereas acciden- tal generalisations are not. But necessity here is not a modal concept, but rather interpreted as short for the semantic predicate “... is necessarily true”. Thus no modal logic is needed. The neces- sity attributed to law sentences is in turn interpreted as “necessary condition for the rest of the the- ory”, which is true since fundamental laws are implicit definitions of theoretical predicates use in the theory.

Early twelfth-century logicians invoked past-tensed statements with future-oriented contents to undermine the assumption that every proposition ‘about the past’ is determinate. In the second half of the century, the notion of future-dependence was used to restrict the scope of necessity per accidens. At some point, this idea began to be applied in theology to solve puzzles surrounding predestination, prescience, prophecy, and faith. In the mid-1160s, Magister Udo quotes some thinkers who insisted that the principle of the necessity of the (...) past should exclude dicta that ‘relate to the future’, such as that he has been predestined. Peter of Poitiers adopted this ‘Ockhamist’ strategy around 1170. We find similar accounts in Simon of Tournai and Alan of Lille, who invoked it in other contexts as well. By the time of Praepositinus of Cremona, Hubert of Pirovano, and Stephen Langton, the restricted principle became something of a common view at Paris. (shrink)

The article presents a formalization of Thomas Aquinas proof for the indestructibility of the human soul. The author of the formalization—the first of its kind in the history of philosophy—is Father Joseph Maria Bocheński. The presentation involves no more than updating the logical symbolism used and accompanies the logical formulae with ordinary language paraphrases in order to ease the reader’s understanding of the formulae. “The fundamental idea of the Thomist proof is of utmost simplicity: things which are destructible are destructible (...) either per se or per accidens; but the human soul is destructible neither per se nor per accidens: therefore the human soul is not destructible”. Bochenski’s words required him to devote considerable effort for the sake of precision of the symbolic language that would be maximally adequate to Thomas’ discourse. Moreover, I have thought it necessary to provide an ample commentary to the traditional and contemporary semantical presuppositions of Aquinas philosophical anthropology in light of Bocheński’s interpretation thereof.

The diversity of interpretations of Aristotle’s treatment of chance and luck springs from an apparent contradiction between the claims that “chance events are for the sake of something” and that “chance events are not for the sake of their outcome.” Chance seems to entail the denial of an end. Yet Aristotle systematically refers it to what is for the sake of an end. This paper suggests that, in order to give an account of chance, a reference to “per accidens (...) causes” is not sufficient. Chance occurs as a parody of teleology; it is a“for-no-purpose” that looks like a purpose. The notion of “irony” is suggested as a way of accounting for a situation that keeps an ambiguity open. The fact that chance is thought of in relation to teleology does not mean that it is “reappropriated” by teleology. Rather,chance reveals a hiatus that betrays the limitation of a language concerned with substances to account for events. (shrink)

As contemporary ethical discourse has highlighted, due to the world’s increasing connectedness, everyday actions can contribute to harmful consequences far removed from everyday experience. I argue that Aquinas’s treatment of consequences can give us insight into our responsibility for such effects of our actions on a global scale. In particular, Aquinas recognises that we are responsible for per accidens effects of good actions performed negligently. Even an unintended per accidens effect may follow with a degree of likelihood that (...) makes it foreseeable, even if not actually foreseen; thus the agent is responsible if he fails to take steps to prevent the negative per accidens effect from occurring. I argue that certain global effects of our actions fit this pattern, namely, they are per accidens effects that nonetheless follow from our actions with a high degree of likelihood. Thus, we have a responsibility to take steps to prevent them. (shrink)

The second chapter is devoted to the analysis of the first introduction of and quarrels over Cartesianism at the University of Utrecht, as determined by the teaching of a Cartesian natural philosophy and physiology by Henricus Regius. First, it is shown how his teaching gave rise to the querelle d’Utrecht (1641), in which two main issues were debated: the rejection of substantial forms, and the characterisation of man as ens per accidens. During the quarrel, questions were raised about the (...) consistency of the new philosophy with theology and – insofar as it raised the problem of the individuation of bodies and species by substantial forms – of the unity of man. Secondly, it is shown how Regius’s peculiar approach to natural philosophy (and physiology) led him to quarrel with Descartes himself in 1645–1648, with regard to two main questions: the nature of mind, and the method of natural philosophy, which Regius interprets in both cases from an empirical standpoint, as he maintains that the nature of mind may consist in matter (according to medical evidence), and that all knowledge has a sensory origin. Accordingly, he paved the way for ‘radical’ interpretations of Descartes which rejected his metaphysics, but also for an approach to a natural philosophy more open to the use of experience. In this chapter, I scrutinise the reasons behind Regius’s approach to physics and metaphysics by paying attention, on the one hand, to his quarrel with Descartes, and on the other to the sources of his methodology, which he largely borrows from medical authors. In conclusion, I show that Cartesianism, in the hands of Regius, might serve as the basis for medicine but could not yet become a full-fledged alternative to Aristotelianism. (shrink)

St. Thomas’s Third Way to prove the existence of God, “Of Possibility and Necessity” (ST 1, q.2, art. 3, response) is one of the most controverted passages in the entire Thomistic corpus. The central point of dispute is that if there were only possible beings, each at some time would cease to exist and, therefore, at some point in time nothing would exist, and because something cannot come from nothing, in such an eventuality, nothing would exist now—a reductio ad absurdum (...) conclusion. Therefore, at least one necessary being must exist. Generations of critics and defenders have contended over St. Thomas’s proof. This article argues that the principle of pros hen analogy is implicit in the Third Way and that once identified explains the ontological dependency of possible beings, as secondary analogates, on the first necessary being, as primary analogate. Thus, without the necessary being as primary analogate, possible beings simply could not exist. The fact that they do exist is evidence for the existence of the necessary being. St. Thomas makes synthesizes the principle of pros hen analogy, as found in Aristotle’s Metaphysics, with the Neoplatonic principle of participation. Aristotle develops pros hen analogy in contradistinction to univocal and equivocal predication as well as to genus in Metaphysics 4.2, 11.3, 12.3-5. Since Scotus and re-enforced by modern analytic logic, philosophers have almost universally regarded any kind of analogical predication as a sub-category of equivocal predication and, thus, implicitly occlude the possibility of considering pros hen analogy in their readings of the Third Way. Distinction of per se and per accidens infinite regress and of radical and natural contingency are also central to understanding the Third Way. While resolving apparent problems in the Third Way, the article also seeks to rehabilitate the doctrine of pros hen analogy as a basic principle in Thomistic and, indeed, Aristotelian metaphysics.

In the last 30 years there has been growing interest in and a greater appreciation of the unique contributions that medieval authors have made to the history of logic. In this thesis, we compare and contrast the modal logics of Robert Kilwardby and John Buridan and explore how their two conceptions of modality relate to and differ from modern notions of modal logic. We develop formal reconstructions of both authors' logics, making use of a number of different formal techniques. In (...) the case of Robert Kilwardby we show that using his distinction between per se and per accidens modalities, he is able to provide a consistent interpretation of the apodictic fragment of Aristotle's modal syllogism and that, by generalising this distinction to hypothetical construction, he can develop an account of connexive logic. In the case of John Buridan we show that his modal logic is a natural extension of the usual Kripke-style possible worlds semantics, and that this modal logic can be shown to be sound and complete relative to a proof-theoretic formalisation of Buridan's treatment of the expository syllogism.

This paper explores the interaction between medicine and metaphysics in modern natural philosophy and especially in Descartes ' philosophy. I argue that Descartes ' hypothetical account of birthmarks in connection with his embryology provides an argumentative proof of the metaphysical necessity of a substantial union between mind and body, which however does not threaten his doctrine of the real distinction between these two substances. It would appear that his argument relies on a temporal conception of alethic modalities and provides a (...) new answer to Henricus Regius who in 1641 claimed that, for Descartes, the human being is an ens per accidens.

The purpose of this study is to investigate the legitimacy of the principle, "The per accidens necessarily implies the per se," as it is found in the writings of St. Thomas Aquinas. Special emphasis will be placed upon the function of this principle in the proofs for God's existence. The relevance of the principle in this latter context can be seen at once when it is observed that it is the key to the solution of the well known "prob (...) lem of infinite regress. " The investigation of the principle in question will be divided into two Parts. A preliminary examination of the function of the principle will be made in Part I: Domains Other Than That of Creature-God. The domains to be considered in this Part are those of accident-substance, change, and knowledge. Employing what is learned of the function of the principle in these areas of application, Part II: The Domain of Creature-God will analyze the role of the principle in the proofs for God's existence. This latter Part will constitute the greater portion of the book, since the domain of creatures in their relation to God is the most significant application of the principle in the writings of St. Thomas. In the course of this investigation, relevant analyses by St. Thomas' commentators - both classical and contemporary - will be considered. Finally, in light of the insights offered by St. (shrink)

Many discussions of per se and per accidens series focus on efficient causality and how a consideration of the metaphysics of the matter can deliver us a primary efficient cause of all that is (God). Drawing on my own previous work on causal series, I offer in this article a model for the understanding of per se causal series wherein the causality involved is that of finality. I then consider whether or not such per se final causal series are (...) infinite. Finally, I consider the implications this has for our conception of God as creator. (shrink)

The diversity of interpretations of Aristotle’s treatment of chance and luck springs from an apparent contradiction between the claims that “chance events are for the sake of something” and that “chance events are not for the sake of their outcome.” Chance seems to entail the denial of an end. Yet Aristotle systematically refers it to what is for the sake of an end. This paper suggests that, in order to give an account of chance, a reference to “per accidens (...) causes” is not sufficient. Chance occurs as a parody of teleology; it is a“for-no-purpose” that looks like a purpose. The notion of “irony” is suggested as a way of accounting for a situation that keeps an ambiguity open. The fact that chance is thought of in relation to teleology does not mean that it is “reappropriated” by teleology. Rather,chance reveals a hiatus that betrays the limitation of a language concerned with substances to account for events. (shrink)

It can be confusing to define the object of an action because it may be unclear if there is a per se or a per accidens order to the end. Three common difficulties in distinguishing between these are that the per se ordering must be either in the nature of the end or in the act, that this ordering to an end is a real and not merely a logical one, and that technology has a tendency to ignore the (...) teleology of natures by breaking things down to their parts for manipulation.

_ Source: _Volume 55, Issue 4, pp 239 - 272 According to Peter Auriol, OFM, efficient causation is a composite being consisting of items belonging to three distinct categories: a change, an action, and a passion. The change functions as the subject bearing action and passion. After presenting Aristotle’s account of action and passion, which constitutes the background to Auriol’s theory of causation, this paper considers Auriol’s interpretation of Aristotle’s account in contrast to an alternative interpretation defended by Hervaeus Natalis (...) and William of Ockham. Finally, it shows how Auriol, on the basis of his interpretation of Aristotle, develops his own account of efficient causation as a composite being. (shrink)

In a following section of the book, under the heading “Causes and Analysis” causes per se and causes per accidens are studied. Predication is per se when the attribute belongs to the intrinsic structure of the subject, or when it is not accidental, and finally when it belongs to the thing itself. All causes can be reduced, Bastit believes, to formal causality.

The debate concerning the so-called U.S. Health and Human Services Contraception Mandate has been adequately framed, in the academic field, within the traditional ethical doctrine on cooperation with evil. This principle will allow us to conclude whether employers may ethically comply with the onerous existing law or not. The discussion has been quite heated, because the practical conclusions authors have reached vary widely, depending on which interpretation of the theory they rely on. In this paper, some of these explanations are (...) addressed and analyzed from the standpoint of the Thomistic theory of action, which is now the most common point of view. This work concludes that, although the Contraception Mandate will most likely be repealed by the current U.S. administration, as things once stood, compliance with it may have been ethically licit in some cases.

This work presents an overview of four different approaches to the problem of future contingency and determinism in temporal logics. All of them are bivalent, viz. they share the assumption that propositions concerning future contingent facts have a determinate truth-value. We introduce Ockhamism, Peirceanism, Actualism and T x W semantics, the four most relevant bivalent alternatives in this area, and compare them from the point of view of their expressiveness and their underlying metaphysics of time.

Peter of Bergomo, one of the first to attempt to compile an index and concordance of Aquinas's works, often noted apparent discrepancies between diverse texts. His entry for "accidens" is no exception since approximately ten percent of its divisions are prefaced by the familiar "oppositum videtur dicere." The reader is left with the task of determining whether Bergomo's notations concern only apparent contradictions or whether St. Thomas indeed made significant alterations in his understanding of the topic. Brown's portrayal of (...) Aquinas's texts in their specific contexts permits a nuanced interpretation of St. Thomas's diverse considerations of the being of accidents which avoids both of the aforementioned alternatives.
