This paper contributes to a growing body of literature focusing on Anton Wilhelm Amo’s account of the mind-body relation. The first aim of this paper is to provide an overview of that literature, bringing together several interpretations of Amo’s account of the mind-body relation and providing a comprehensive overview of where the debate stands so far. Doing so reveals that commentary is split between those who take Amo to adopt a Leibnizian account of pre-established harmony between mind and body (Smith (...) 2015, Emma-Adamah 2015) and those who argue that Amo adopts a theory of occasional causation (Meyns 2019, Walsh 2019). Both views deny that the body is the efficient cause of the mind’s ideas but while the Leibnizian account holds that ideas exist innately in the mind, the occasional causation account maintains that the body is their occasional cause. That is, on this reading of Amo, sensations in the body are the ‘occasion’ on which the mind efficiently causes its own ideas. The second aim of this paper – which promises to take this interpretative debate in a new direction – is to demonstrate that we should in fact attribute to Amo a specific version of occasional causation known as 'concurrentism'. Concurrentism is the view that, while the mind does efficiently cause its own ideas, it can only do so with the assistance (or ‘concurrence’) of God. In other words, on this view, God makes possible the efficient causal activity of the human mind in generating ideas, in response to ‘occasions’ in the body. (shrink)

Suppose that you prefer A to B, B to C, and C to A. Your preferences violate Expected Utility Theory by being cyclic. Money-pump arguments offer a way to show that such violations are irrational. Suppose that you start with A. Then you should be willing to trade A for C and then C for B. But then, once you have B, you are offered a trade back to A for a small cost. Since you prefer A to B, you (...) pay the small sum to trade from B to A. But now you have been turned into a money pump. You are back to the alternative you started with but with less money. This Element shows how each of the axioms of Expected Utility Theory can be defended by money-pump arguments of this kind. The Element also defends money-pump arguments from the standard objections to this kind of approach. This title is also available as Open Access on Cambridge Core. (shrink)

This volume contains 12 papers addressed to researchers and advanced students in informal logic and related fields, such as argumentation, formal logic, and communications. Among the issues discussed are attempts to rethink the nature of argument and of inference, the role of dialectical context, and the standards for evaluating inferences, and to shed light on the interfaces between informal logic and argumentation theory, rhetoric, formal logic and cognitive psychology.

How language works — its functions, mechanisms, and limitations — matters to the early moderns as much as it does to contemporary philosophers. Many of the moderns make reflection on language central to their philosophical projects, both as a tool for explaining human cognition and as a weapon to be used against competing views. Even in philosophers for whom language is less central, we can find important connections between their views on language and their other philosophical commitments.

I argue that many of the priority rankings that have been proposed by effective altruists seem to be in tension with apparently reasonable assumptions about the rational pursuit of our aims in the face of uncertainty. The particular issue on which I focus arises from recognition of the overwhelming importance and inscrutability of the indirect effects of our actions, conjoined with the plausibility of a permissive decision principle governing cases of deep uncertainty, known as the maximality rule. I conclude that (...) we lack a compelling decision theory that is consistent with a longtermist perspective and does not downplay the depth of our uncertainty, while also supporting orthodox effective altruist conclusions about cause prioritization.

In early modern times it was not uncommon for thinkers to tease out from the nature of God various doctrines of substantial physical and metaphysical import. This approach was particularly fruitful in the so-called beast-machine controversy, which erupted following Descartes’ claim that animals are automata, that is, pure machines, without a spiritual, incorporeal soul. Over the course of this controversy, thinkers on both sides attempted to draw out important truths about the status of animals simply from the notion or attributes (...) of God. Automatists – led by Nicolas Malebranche and Antoine Dilly – developed six such arguments, appealing to divine justice, providence, economy, glory (twice) and wisdom, while opponents to animal automatism developed two arguments, appealing to divine wisdom and goodness. In this article I shall examine the substance of all eight of these arguments, along with their origins, patronage, and variations, and the objections they elicited from opponents, with the aim of determining their suitability for use in contemporary debates about animal sentience and consciousness, and hence their relevance for contemporary philosophers.

This paper deals with what has been called "ars inveniendi" (’art of finding‘) in antiquity, medieval and early modern times. A survey of different techniques of finding tenable and relevant arguments is presented (among them, the Topical tradition, Status theory, Debate theory, Encyclopedic systems, Creativity techniques). Their advantages and disadvantages are critically compared. It is suggested that a mixture of strategies of finding arguments should be used. Finally, a few remarks showing the relationship beween the strategies of finding arguments and (...) creativity in general are given. (shrink)

Philosophers of the modern period are often presented as having made an elementary error: that of confounding the attitude one adopts toward a proposition with its content. By examining the works of Locke and the Port-Royalians, I show that this accusation is ill-founded and that Locke, in particular, has the resources to construct a theory of propositional attitudes.

Descartes claims that God is a substance, and that mind and body are two different and separable substances. This paper provides some background that renders these claims intelligible. For Descartes, that something is real means it can exist in separation, and something is a substance if it does not depend on other substances for its existence. Further, separable objects are correlates of distinct ideas, for an idea is distinct (in an objective sense) if its object may be easily and clearly (...) separated from everything that is not its object. It follows that if our idea of God is our most distinct idea, as Descartes claims, then God must be a substance in the Cartesian sense of the term. Also, if we can have an idea of a thinking subject which does not in any sense refer to bodily things, and if bodily things are substances, then mind and body must be two different substances.

In his groundbreaking work of 1969, Spinoza's Metaphysics: An Essay in Interpretation, Edwin Curley attacked the traditional understanding of the substance-mode relation in Spinoza, according to which modes inhere in substance. Curley argued that such an interpretation generates insurmountable problems, as had already been claimed by Pierre Bayle in his famous Dictionary entry on Spinoza. Instead of having modes inhere in substance Curley suggested that the modes’ dependence upon substance should be interpreted in terms of (efficient) causation, i.e., as committing (...) Spinoza to nothing over and above the claim that substance is the (efficient) cause of the modes. These bold and fascinating claims generated one of the most important scholarly controversies in Spinoza scholarship of the past thirty-five years. In this paper I argue against Curley’s interpretation and attempt to reestablish the traditional understanding of Spinozistic modes as inhering in God and as predicated of God. I also criticize Curley’s philosophical motivation for suggesting this interpretation. In order to show that, for Spinoza, modes are predicated of - and inhere in - substance, I will proceed in the following manner. First, I will summarize Curley’s arguments against substance-mode inherence and present his alternative interpretation of the substance-mode relation. I will then present what I consider to be the most compelling arguments against Curley’s interpretation. Some of these arguments have already been suggested in the literature of the past thirty years (and by Bayle); however, as far as I know, most of the arguments I will be making are new. In the subsequent section I will respond to objections that Curley and Bayle advance against Spinoza’s view of God as the substratum in which all things inhere. Finally, I will address whether Spinozistic modes are predicated of (and not only inhere in) substance, and whether Spinoza considered modes to be particular properties (or “tropes,” in the jargon of contemporary metaphysics). Since Bayle’s claims will be used both in support of and against Curley’s interpretation, it would be appropriate to say a few introductory words on Bayle’s stance. In his Spinoza entry, Bayle criticizes Spinoza’s claim that all things are modes of God, claiming that it “is the most monstrous hypothesis that could be imagined, the most absurd, and the most diametrically opposed to the most evident notions of our mind.” Bayle, however, has no doubt that when Spinoza claims that all things are modes of God, Spinoza means that all things inhere in God. Curley embraces Bayle’s arguments against Spinoza, but uses them in order to claim that we should not ascribe to Spinoza a view which is allegedly shown by Bayle to be absurd. What we should do, Curley argues, is to reinterpret the substance-mode relation as a relation of causal dependence, which would set Spinoza free from Bayle’s hook. Interestingly, as we shall soon see, Bayle himself discusses and rejects a very similar revisionary interpretation of the substance-mode relation. (shrink)

This paper aims at specifying the complex links which two major and polemically related 18th-century linguistic theories James Harris' universal grammar in Hermes (1751) and John Horne Tooke's system of etymology in the Diversions of Purley (1786, 1804) bear to empiricism. It describes both the ideologicalethical determining factors of the theories and the epistemological consequences dependent upon their respective philosophical orientation (Harris using classical Greek philosophy against empiricism, Tooke criticizing Locke's semantics along Hobbesian lines). The effects within the linguistic theories (...) are examined through a comparison of the theories of determination which follow from divergent theses concerning abstraction. The analysis proposed in this paper exemplifies once more the historical question of the exact location of the compatibility/incompatibility between empiricist and non-empiricist linguistic theories.

This article canvases the main areas of controversy: the nature of Lockean signification and his position on propositions and particles.

In a series of papers, Sperber provides the following analysis of the phenomenon of ill-understood belief (or 'quasi-belief', as I call it): (i) the quasi-believer has a validating meta-belief, to the effect that a certain representation is true; yet (ii) that representation does not give rise to a plain belief, because it is 'semi-propositional'. In this paper I discuss several aspects of this treatment. In particular, I deny that the representation accepted by the quasi-believer is semantically indeterminate, and I reject (...) Sperber's claim that quasi-belief is a credal attitude distinct from plain belief. (shrink)

Discussion of the Aristotelian syllogistic over the last sixty years has arguably centered on the question whether syllogisms are inferences or implications. But the significance of this debate at times has been taken to concern whether the syllogistic is a logic or a theory, and how it ought to be represented by modern systems. Largely missing from this discussion has been a study of the few passages in the Prior Analytics where Aristotle provides explicit guidance on how to individuate syllogisms. (...) I argue that syllogisms are individuated by unordered premise pairs and so may be fruitfully thought of as multi-succedent sequents. I conclude by drawing a few consequences for the representation of the syllogistic. (shrink)

The paper focuses on the epistemology developed by Richard Burthogge, the lesser-known seventeenth-century English philosopher, and author, among other works, of Organum Vetus & Novum (1678) and An Essay upon Reason and the Nature of Spirits (1694). Although his ideas had a minimal impact on the philosophy of his time, and have hitherto not been the subject of a detailed study, Burthogge’s writings contain a highly original concept of idealistic constructivism, anticipating (relatively speaking) Kant’s idealism. At the same time, some (...) interesting implications for the issue of self-interpretation and self-identity can be derived from his account of the mind. At the core of Burthogge’s epistemological position is a remarkable idea of structural and functional similarity between the three human cognitive faculties, that is between reasoning, sensation and imagination. Accordingly, every cognition, intellectual as well as sensuous, contains in its structure an object-directed operation of apprehending and thus can be viewed as an intentional act in a broad sense of the term. An immediate consequence of this claim for both mind and object is that they cannot be reduced to a pure stream of sense data, but on the contrary are to be considered ontologically independent from the content of a cognitive act. Furthermore, an object of cognition is never presented to the mind directly, as it is in itself, but always under the modus concipiendi, a particular form or manner of conceiving, specific to human cognitive powers due to their internal structure. As a result, Burthogge clearly anticipates Kant in claiming that it is impossible to know reality in itself, and in situating human consciousness as if in between two unknowable spheres: the external and internal one. Since these restrictions are imposed not only on external, but also on internal cognition, that is on self-knowledge, they lead to considerable difficulties regarding the mind’s identity. Basically, two principal strategies to address this issue are available in the post-Cartesian framework of seeing the mind as an ontologically independent entity, and both of them appear to be ineffective when employed in Burthogge’s epistemology. First, the mind identity can be grounded in some extra-mental factors, preferably in matter. However, with no access to the external world in itself, and with the scope of knowledge restricted to mental phenomena, the mind’s identity cannot be defined in terms of relationship with the reality of which it knows nothing except that it exits. The second option is to explain personal identity by referring it to the intrinsic properties of the mind. Nevertheless, this strategy also faces insuperable obstacles, and for the same reasons as the former does. Since self-knowledge is no exception to the structural-functional principles imposed on cognition, the mind can also be known only under the subjective conditions of conceiving. It is, therefore, just as unknowable in itself as the external things are. The main purpose of the paper is to explore this aspect of Burthogge’s philosophy. (shrink)

This paper studies the notions of conceptual grounding and conceptual explanation (which includes the notion of mathematical explanation), with an aim of clarifying the links between them. On the one hand, it analyses complex examples of these two notions that bring to the fore features that are easily overlooked otherwise. On the other hand, it provides a formal framework for modeling both conceptual grounding and conceptual explanation, based on the concept of proof. Inspiration and analogies are drawn with the recent (...) research in metaphysics on the pair metaphysical grounding–metaphysical explanation, and especially with the literature in philosophy of science on the pair causality-causal explanation.

No presente artigo, pretendo analisar uma das interpretações da distinção transcendental entre fenômenos e coisas em si mesmas, a tese dos dois aspectos [the two-aspect view]. Meu objetivo é indicar e esclarecer alguns pressupostos fundamentais dessa interpretação, nem sempre explicitados pelos seus defensores. Um dos maiores desafios dessa interpretação é explicar como é possível conciliá-la com a tese kantiana da não espacialidade das coisas em si mesmas. Pretendo mostrar que a conciliação pressupõe a satisfação das três seguintes condições: em primeiro (...) lugar, é necessário admitir que, para Kant, a relação cognitiva entre objeto e sujeito cognoscente é _constitutiva_ do objeto; em segundo lugar, é preciso conceber a identidade entre fenômeno e coisa em si mesma como uma _identidade relativa_, não absoluta; em terceiro lugar, é preciso admitir que certos enunciados sobre o objeto da cognição possuem uma estrutura lógica peculiar, a estrutura de um _juízo reduplicativo_. A análise desses pressupostos visa contribuir para a elucidação dos compromissos teóricos da tese kantiana do idealismo transcendental. (shrink)

This article presents a novel reading of Descartes’s critique of the traditional syllogistic. The reading differs from those previously presented by scholars who regard Descartes’s critique as a version of a well-known argument: that syllogisms are circular or non-ampliative and thus trivial. It is argued that Descartes did not see syllogisms as defective in themselves. For him the problem was rather that anyone considering a valid and informative syllogism must already know, by an intuition wholly independent of the syllogism, that (...) the conclusion follows from the premises. Moreover, without such an intuition the syllogistic on its own is incapable of determining whether the consequence truly holds. Thus the syllogistic is useless unless accompanied by an intuition that renders it otiose. This reading of Descartes’s view is supported and explained by examples drawn from Descartes’s writing and from the Port-Royal Logic—one of the first attempts to develop a logical system on Cartesian principles.

In this paper we explain our pretense account of truth-talk and apply it in a diagnosis and treatment of the Liar Paradox. We begin by assuming that some form of deflationism is the correct approach to the topic of truth. We then briefly motivate the idea that all T-deflationists should endorse a fictionalist view of truth-talk, and, after distinguishing pretense-involving fictionalism (PIF) from error- theoretic fictionalism (ETF), explain the merits of the former over the latter. After presenting the basic framework (...) of our PIF account of truth-talk, we demonstrate a few advantages it offers over T-deflationist accounts that do not explicitly acknowledge pretense at work in the discourse. In turning to the Liar Paradox, we explain how the quasi-anaphoric functioning that our account attributes to truth-talk provides a diagnosis of the Liar Paradox (and other instances of semantic pathology) as having no content—in the sense of not specifying any of what we call M-conditions. At the same time, however, we vindicate the intuition that we can understand liar sentences, thereby avoiding one standard objection to “meaningless strategy” responses to the Liar Paradox. With this diagnosis in place, we then, by way of treatment, introduce a new predicate, ‘semantically defective’, and show how the explanation we give for its application allows for a consistent, yet revenge-immune, (dis)solution of the Liar Paradox, and semantic pathology generally.

While evidence-based medicine (EBM) is often accused on relying on a paradigm of 'absolute truth', it is in fact highly consistent with Karl Popper's criterion of demarcation through falsification. Even more relevant, the first three steps of the EBM process are closely patterned on Popper's evolutionary approach of objective knowledge: (1) recognition of a problem; (2) generation of solutions; and (3) selection of the best solution. This places the step 1 of the EBM process (building an answerable question) in a (...) pivotal position for the understanding of the whole process, and underscores a few aspects which are often overlooked in EBM courses. First in this step internal evidence (including personal expertise) must be appraised and integrated in the problem. Second, issues of applicability of the possible solution should be anticipated. Third, and possibly more important, the goal of the intervention should be set at this stage (typically by choosing the outcome in a PICO question). Depending whether or not goals depend on the goals of others, and whether they concern others' voluntary behaviour, goals may be classified as self-serving, moral, altruistic or moralistic. Thus, delicate ethical questions must be addressed at this stage, which means that patient preferences and values must be carefully sought, so that empathy, counselling and narrative medicine must be mastered to be able to formulate correctly an answerable question. The need to modify the current description of the EBM process to increase the recognition of implicit assumptions and increase the consistency of this model is discussed. (shrink)

According to the received view (Bocheński, Kneale), from the end of the fourteenth to the second half of nineteenth century, logic enters a period of decadence. If one looks at this period, the richness of the topics and the complexity of the discussions that characterized medieval logic seem to belong to a completely different world: a simplified theory of the syllogism is the only surviving relic of a glorious past. Even though this negative appraisal is grounded on good reasons, it (...) overlooks, however, a remarkable innovation that imposes itself at the beginning of the sixteenth century: the attempt to connect the two previously separated disciplines of logic and mathematics. This happens along two opposite directions: the one aiming to base mathematical proofs on traditional (Aristotelian) logic; the other attempting to reduce logic to a mathematical (algebraical) calculus. This second trend was reinforced by the claim, mainly propagated by Hobbes, that the activity of thinking was the same as that of performing an arithmetical calculus. Thus, in the period of what Bocheński characterizes as ‘classical logic’, one may find the seeds of a process which was completed by Boole and Frege and opened the door to the contemporary, mathematical form of logic.

It is generally assumed that Descartes invokes “objective being in the intellect” in order to explain or describe an idea’s status as being “of something.” I argue that this assumption is mistaken. As emerges in his discussion of “materially false ideas” in the Fourth Replies, Descartes recognizes two senses of ‘idea of’. One, a theoretical sense, is itself introduced in terms of objective being. Hence Descartes can’t be introducing objective being to explain or describe “ofness” understood in this sense. Descartes (...) also appeals to a pretheoretical sense of ‘idea of’. I will argue that the notion of objective being can’t serve to explain or describe this “ofness” either. I conclude by proposing an alternative explanation of the role of objective being, according to which Descartes introduces this notion to explain the mind’s ability to attain clear and distinct ideas.

Logic is usually thought to concern itself only with features that sentences and arguments possess in virtue of their logical structures or forms. The logical form of a sentence or argument is determined by its syntactic or semantic structure and by the placement of certain expressions called “logical constants.”[1] Thus, for example, the sentences Every boy loves some girl. and Some boy loves every girl. are thought to differ in logical form, even though they share a common syntactic and semantic (...) structure, because they differ in the placement of the logical constants “every” and “some”. By contrast, the sentences Every girl loves some boy. and Every boy loves some girl. are thought to have the same logical form, because “girl” and “boy” are not logical constants. Thus, in order to settle questions about logical form, and ultimately about which arguments are logically valid and which sentences logically true, we must distinguish the “logical constants” of a language from its nonlogical expressions.

Ranging from Alan Turing’s seminal 1936 paper to the latest work on Kolmogorov complexity and linear logic, this comprehensive new work clarifies the relationship between computability on the one hand and constructivity on the other. The authors argue that even though constructivists have largely shed Brouwer’s solipsistic attitude to logic, there remain points of disagreement to this day. Focusing on the growing pains computability experienced as it was forced to address the demands of rapidly expanding applications, the content maps the (...) developments following Turing’s ground-breaking linkage of computation and the machine, the resulting birth of complexity theory, the innovations of Kolmogorov complexity and resolving the dissonances between proof theoretical semantics and canonical proof feasibility. Finally, it explores one of the most fundamental questions concerning the interface between constructivity and computability: whether the theory of recursive functions is needed for a rigorous development of constructive mathematics. This volume contributes to the unity of science by overcoming disunities rather than offering an overarching framework. It posits that computability’s adoption of a classical, ontological point of view kept these imperatives separated. In studying the relationship between the two, it is a vital step forward in overcoming the disagreements and misunderstandings which stand in the way of a unifying view of logic. (shrink)

Neo-Kantianism emerged over the course of the 1860s and it occupied a leading position in the German universities from the 1870s until the First World War. Demands for getting "back to Kant" had become common since the early 1860s, and these demands were discussed in the meetings of the Philosophical Society of Berlin (Philosophische Gesellschaft zu Berlin; PGB), which was the international organization of Hegelians. In this paper I address some reactions among the PGB members to the 1860s Kant revival. (...) The journal "Der Gedanke", the organ of the PGB, reported closely how Kant returned to the spotlight of German philosophy. The reactions of the PGB members to the Kant revival was not only critical. Over the course of the 1860s the interest on Kant among the members grew little by little. (shrink)

Os demonstrativos foram considerados tradicionalmente como expressões referenciais. É o que encontramos na história da filosofia desde o início da tradição gramatical ocidental que sempre tratou os demonstrativos como pronomes. A maior provocação no livro de King consiste precisamente em romper com essa tradição ao apresentar os demonstrativos complexos (“esta mesa”, “aquele homem” etc.) como termos quantificados (e, portanto, termos não-referenciais). King apóia seu tratamento sobre exemplos escolhidos que parecem favorecer sua tese, como “aquele arquiteto que construiu essas pirâmides era (...) um gênio”, quando o locutor da frase não tem nenhum alvo referencial em mente e não pode apontar para ninguém no contexto da enunciação. Mostrarei: 1) que o tratamento de King representa uma tremenda ruptura com a tradição e desconsidera as intuições de gerações e gerações de lingüistas e filósofos da linguagem; 2) que King apóia sua tese em evidências de natureza puramente sintática sem discutir metodologicamente o peso que devemos atribuir a essas evidências sintáticas nas discussões de semântica; 3) que King não leva em conta todos os dados disponíveis, forçando os dados por ele recolhidos a entrar numa mesma teoria unificada, mas, para isso, paga um preço alto: uma redundância inaceitável na semântica das expressões demonstrativas simples.

Recent literature on the Young Hegelians attests to a renewed appreciation of their philosophical and political significance. Important new studies have linked them to the literary and political currents of their time, traced the changing patterns of their relationships with early French socialism, and demonstrated the affinity of their thought with Hellenistic theories of self-consciousness. The conventional interpretative context, which focuses on the left-Hegelian critique of religion and the problem of the realisation of philosophy, has also been decisively challenged. Ingrid (...) Pepperle emphasizes instead the centrality of practical philosophy, notably Hegel's dialectic of objectification, arguing that Bruno Bauer in particular derives from this a doctrine of autonomy with politically revolutionary implications.

This article examines Cohen’s “transcendental method”, Windelband’s “critical method”, the neo-Kantian distinctions between natural science and the humanities (i. e., human or cultural sciences), and Weber’s account of ideal-typical explanations. The Marburg and the Southwest Schools of neo-Kantianism have in common that their respective philosophies of science focused on method, but they substantially differ in their approaches. Cohen advanced the “transcendental method”, which was taken up and transformed by Natorp and Cassirer; later, it became influential in neo-Kantian approaches to 20th (...) century physics. Windelband distinguished between facts and values, linking the former to the “genetic” method of history and the latter to the “critical” method of philosophy; and between the “nomothetic” and “idiographic” methods of the empirical sciences, a distinction further elaborated by Rickert. The distinction does not give rise to a sharp discrimination but is rather what Weber would later call an ideal type. All these approaches contribute in different ways to understanding the structure of scientific knowledge, focusing on different aspects of the general path of the empirical sciences between rationalism and empiricism.

This article examines how the theory of proportions was explained during the second half of the seventeenth century in the works of Andreas Tacquet, Antoine Arnauld, Ignace Gaston Pardies, Bernard Lamy, and Jacques Rohault. These five authors had very different conceptions of this subject, and on one hand, they show that this question was not forgotten, even after the Geometry of Descartes, and on the other hand, their work displays the progressive transformation of mathematical objects. While Tacquet deepened Euclidean thought, (...) the others stopped taking the Euclidean model as paradigmatic and tried to change the order of the Elements and to establish book V of Euclid in new ways. We shall see that this multiplicity of the approaches highlights both the vitality of the reflections and the difficulty in developing a new ontology of mathematics. Some of them nevertheless opened new perspectives that were to bloom only much later. We shall also see the increasingly important place of the algebra as time went by. (shrink)

In the 1680s, Gottfried Leibniz and Antoine Arnauld engaged in a philosophically rich correspondence. One issue they discuss is modal metaphysics – questions concerning necessity, possibility, and essence. While Arnauld's contributions to the correspondence are considered generally astute, his contributions on this issue have not always received a warm treatment. I argue that Arnauld's criticisms of Leibniz are sophisticated and that Arnauld offers his own Cartesian account in its place. In particular, I argue that Arnauld offers an account of possibility (...) that is actualist, modal actualist and essence-based. (shrink)

Despite its basically syllogistic character, Richard Whately's Elements of logic presents the subject in a modern theoretical setting. Whately, for instance, regarded logic as an abstract science, and defined the syllogism as a purely formal device to be used as a means of determining the validity of all arguments. In this paper, I argue that such instances of abstractive ascent place Whately's theory in closer proximity to later 19th-century developments than to the work of his 17th-century predecessors. In addition to (...) discussing the theory itself, other sections deal with its historical setting, and various reactions to it. (shrink)

In this paper, I defend a novel interpretation of Antoine Arnauld’s conception of God, namely a ‘partially hidden’ conception of God. I focus on divine simplicity and whether God acts for reasons. I argue that Arnauld holds the view that: God, God’s action and God’s attributes are (i) identical, and (ii) conceptually distinct, but that (iii) there are no conceptual priorities among them. Next, I argue that Arnauld’s view about whether God has any type of reasons is agnosticism, but that (...) there are certain types of reasons we know that God does not have, e.g., practical reasons.

The studies that make up this book were written and brought together to honor the memory of Jan Pinborg. His unexpected death in 1982 at the age of forty-five shocked and saddened students of medieval philosophy everywhere and left them with a keen sense of disappoint ment. In his fifteen-year career Jan Pinborg had done so much for our field with his more than ninety books, editions, articles, and reviews and had done it all so well that we recognized him (...) as a leader and counted on many more years of his scholarship, his help, and his friendship. To be missed so sorely by his international colleagues in an academic field is a mark of Jan's achievement, but only of one aspect of it, for historians of philosophy are not the only scholars who have reacted in this way to Jan's death. In his decade and a half of intense productivity he also acquired the same sort of special status among historians of linguistics, whose volume of essays in his memory is being G. L. Bursill-Hall almost simultane published under the editorship of ously with this one. Sten Ebbesen, Jan's student, colleague, and successor as Director of the Institute of Medieval Greek and Latin Philology at the University of Copenhagen, has earned the gratitude of all of us by memorializing Jan 1 in various biographical sketches, one of which is accompanied by a 2 complete bibliography of his publications.

This paper intends to deal with Condillacian Linguistics. Although the Condillacian philosophy of mind and analysis of language were the most important in the late eighteenth century, none of them is mentioned in Chomsky's work (1966, Cartesian Linguistics). It would be useful for the history of Western thought if Chomsky's monumental error were generally recognized and if Condillacian Linguistics were at last to find the place it rightly deserves. The main thesis of Condillac's linguistic ideas (language is the first step (...) in the analysis of thought) is briefly presented with reference to its context and consequences. (shrink)

Peter Geach describes the 'doctrine of distribution' as the view that a term is distributed if it refers to everything that it denotes, and undistributed if it refers to only some of the things that it denotes. He argues that the notion, so explained, is incoherent. He claims that the doctrine of distribution originates from a degenerate use of the notion of ?distributive supposition? in medieval supposition theory sometime in the 16th century. This paper proposes instead that the doctrine of (...) distribution occurs at least as early as the 12th century, and that it originates from a study of Aristotle's notion of a term's being ?taken universally?, and not from the much later theory of distributive supposition. A detailed version of the doctrine found in the Port Royal Logic is articulated, and compared with a slightly different modern version. Finally, Geach's arguments for the incoherence of the doctrine are discussed and rejected. (shrink)

Throughout more than two millennia philosophers adhered massively to ideal standards of scientific rationality going back ultimately to Aristotle’s Analytica posteriora . These standards got progressively shaped by and adapted to new scientific needs and tendencies. Nevertheless, a core of conditions capturing the fundamentals of what a proper science should look like remained remarkably constant all along. Call this cluster of conditions the Classical Model of Science . In this paper we will do two things. First of all, we will (...) propose a general and systematized account of the Classical Model of Science. Secondly, we will offer an analysis of the philosophical significance of this model at different historical junctures by giving an overview of the connections it has had with a number of important topics. The latter include the analytic-synthetic distinction, the axiomatic method, the hierarchical order of sciences and the status of logic as a science. Our claim is that particularly fruitful insights are gained by seeing themes such as these against the background of the Classical Model of Science. In an appendix we deal with the historiographical background of this model by considering the systematizations of Aristotle’s theory of science offered by Heinrich Scholz, and in his footsteps by Evert W. Beth. (shrink)

Consider a group of people whose preferences satisfy the axioms of one of the current versions of utility theory, such as von Neumann-Morgenstern (1944), Savage (1954), or Bolker-Jeffrey (1965). There are political and economic contexts in which it is of interest to find ways of aggregating these individual preferences into a group preference ranking. The question then arises of whether methods of aggregation exist in which the group’s preferences also satisfy the axioms of the chosen utility theory, and in which (...) at the same time the aggregation process satisfies certain plausible conditions (e.g., the Pareto conditions below).

In this paper, I argue that there are cases of explanatory induction in mathematics. To do so, I first introduce the notion of explanatory definition in the context of mathematical explanation. A large part of the paper is dedicated to introducing and analyzing this notion of explanatory definition and the role it plays in mathematics. After doing so, I discuss a particular inductive definition in advanced mathematics—CW\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${ CW}$$\end{document}-complexes—and argue that it is (...) explanatory. With this, we see that there are cases of explanatory induction. (shrink)

This paper compares the features and methods of the two leading implemented systems that offer a tool for helping a user to find or invent arguments to support or attack a designated conclusion, the Carneades Argumentation System and the IBM Watson Debater tool. The central aim is to contribute to the understanding of scholars in informal logic, rhetoric and argumentation on how these two software systems can be useful for them. One contribution of the paper is to explain to these (...) potential users how the two tools are applicable to the task of inventing arguments by using some simple illustrative examples. Another is to redefine the structure of argument invention as a procedure. (shrink)

D'Alembert's Preliminary Discourse, a once‐influential eighteenth‐century consideration of the utility of the humanities, is relevant to contemporary concerns about the declining importance of humanistic education. A sympathetic appraisal of d'Alembert's critique of humanistic erudition as largely useless can serve as a starting point for reconceiving of the humanities as studies that help train the professionals who administer the institutions of modern society to better understand their own commitments.
