Walter Sinnott-Armstrong argues that moral disagreement and widespread moral bias pose a serious problem for moral intuitionism. Seneca’s view that we just recognise the good could be criticised using a similar argument. His approach to argumentation offers a way out, one that may serve as a model for a revisionary intuitionism.

In this paper we provide an interpretation of Aristotle's rule for the universal quantifier in Topics Θ 157a34–37 and 160b1–6 in terms of Paul Lorenzen's dialogical logic. This is meant as a contribution to the rehabilitation of the role of dialectic within the Organon. After a review of earlier views of Aristotle on quantification, we argue that this rule is related to the dictum de omni in Prior Analytics A 24b28–29. This would be an indication of the dictum’s origin in (...) the context of dialectical games. One consequence of our approach is a novel explanation of the doctrine of the existential import of the quantifiers in dialectical terms. After a brief survey of Lorenzen's dialogical logic, we offer a set of rules for dialectical games based on previous work by Castelnérac and Marion, to which we add here the rule for the universal quantifier, as interpreted in terms of its counterpart in dialogical logic. We then give textual evidence of the use of that rule in Plato's dialogues, thus showing that Aris... (shrink)

In Nicomachean Ethics 7.7 (= Eudemian Ethics 6.7), Aristotle distinguishes softness (malakia) from lack of self-control (akrasia) and endurance (karteria) from self-control (enkrateia). This paper argues that unqualified softness consists of a disposition to give up acting to avoid the painful toil (ponos) required to execute practical resolutions, and (coincidentally) to enjoy the pleasures of rest and relaxation. The enduring person, in contrast, persists in her commitments despite the painful effort required to enact them. Along the way, I argue that (...) this interpretation qualifies our understanding of the pleasures and pains with which temperance and intemperance are concerned. (shrink)

We examine the issues concerning the legality and ethicality of the Second Amendment right to bear arms balanced by the employer's duty to provide a safe workplace for its employees. Two court rulings highlight this balancing act: McDonald et al. v. City of Chicago et al. and District of Columbia v. Heller. “Stand Your Ground” and “Castle Doctrine” laws in the recent Trayvon Martin shooting on February 26, 2012 are also applicable. Various ethical frameworks examine the firearms debate by viewing (...) the Second Amendment from three perspectives. These include a pro‐gun perspective drawing upon libertarianism and fundamental rights; a moderate gun perspective drawing upon consequentialism and stakeholder theory; and finally, an anti‐gun perspective drawing upon a Public Health Ethics and peace ethics approach. We explore the issue of gun control from a business perspective as employers face ethical decisions in responding to legislation that allows guns in the workplace and/or in employer parking lots while still being responsible to provide a safe workplace for their employees. We make recommendations regarding how companies should manage by proactively avoiding legal challenges to employees' rights to own and carry guns into the workplace. This includes emphasis on enhanced security, Human Resource policies and monitoring rapidly changing laws. (shrink)

The hypothesis formulated by Usener and Diels that Theophrastus’ De sensibus is a crucial source of relevant sections of the Placita is insufficiently supported by the evidence. Of the fifteen Placita chapters dealing with sense perception and cognition, only a few are related to the treatise.

Aristotle’s theory of causes requires a first, unmoved mover outside the sublunary world, along with soul as first and unmoved mover in the natural world below. Aristotle separates the charmed group of causes headed by soul that are jointly sufficient for typical animal behaviour from external causes. The border between external and charmed is permeable: crops growing in the field are co-opted to become an instrument of soul that nourishes the animal. (Instruments of soul like the sumphuton pneuma are internal (...) to the animal from the start.) But no causes, not even the Unmoved Mover, may supersede soul as unmoved mover. (shrink)

In Posterior Analytics II 19 Aristotle likens the way in which sense perception gives rise to knowledge of the universal to the way in which one soldier’s ceasing his flight from the enemy leads other soldiers to do the same ‘heôs epi archên êlthen.’ Although the remark seems intended to characterize knowledge as the end result of an accumulative process, the concluding reference to ‘a starting point’ or archê has no clear meaning. I argue that the phrase can be plausibly (...) understood in light of Aristotle’s explanation of how a single calm thought can spread calm to other thoughts (Problems 917a29-33) and a single cloud can serve as a starting point (archê) for a revival of stormy weather (Problems 941a9-13). In addition, Aristotle elsewhere (e.g. Generation of Animals 788a13-16) speaks of the archê as the person or thing which initiates a process. Thus, when one soldier’s stopping causes another soldier to stop, this process can continue ‘until they come to the one who initiated the process.’ . (shrink)

It is often assumed that Aristotle, Boethius, Chrysippus, and other ancient logicians advocated a connexive conception of implication according to which no proposition entails, or is entailed by, its own negation. Thus Aristotle claimed that the proposition ‘if B is not great, B itself is great […] is impossible’. Similarly, Boethius maintained that two implications of the type ‘If p then r’ and ‘If p then not-r’ are incompatible. Furthermore, Chrysippus proclaimed a conditional to be ‘sound when the contradictory of (...) its consequent is incompatible with its antecedent’, a view which, in the opinion of S. McCall, entails the aforementioned theses of Aristotle and Boethius. Now a critical examination of the historical sources shows that the ancient logicians most likely meant their theses as applicable only to ‘normal’ conditionals with antecedents which are not self-contradictory. The corresponding restrictions of Aristotle’s and Boethius’ theses to such self-consistent antecedents, however, turn out to be theorems of ordinary modal logic and thus don’t give rise to any non-classical system of genuinely connexive logic,.

This paper reconstructs the function argument of Aristotle’s Eudemian Ethics 2.1. The argument seeks to define happiness through the method of division; shows that the highest good is better than all four of the goods of the soul, not only two, as commentators have thought; and unlike the Nicomachean argument, makes the highest good definitionally independent of the human function.

Anyone interested in philosophical argumentation should be prepared to study philosophical debates and controversies because it is an intensely dialogical, and even contentious, genre of argumentation. There is hardly any other way to do them justice. This is the reason why the present special issue addresses philosophical argumentation within philosophical debates. Of the six articles in this special issue, one deals with a technical aspect, the diagramming of arguments, another contrasts two moments in philosophical argumentation, Antiquity and the twentieth century, (...) focusing on the use of refutation, and the remaining four analyze particular philosophical controversies. The controversies analyzed differ significantly in their characteristics (time, extension, media, audience,…). Hopefully, this varied sample will illuminate some salient aspects of philosophical argumentation, its representation and variations throughout history. We are fully aware that, given the scarcity of previous studies of philosophical debates from the perspective of argumentation theory, the following specimens of analysis must have several shortcomings. But it is a well-known adage that the hardest part is the beginning. That is what we tried to achieve here, no more, but no less either. (shrink)

This paper advances a philosophical interpretation of Hegel's Logic as defending a metaphysics, which includes an absolute, itself comparable to God in other systems of metaphysics of interest to Hegel, including Aristotle's and Spinoza's. Two problems are raised which can seem to block the prospects for such a metaphysically inflationary interpretation. The key to resolving these problems is consideration of the kinds of metaphysical priority that Hegel sees in Aristotle. This allows us to build a philosophical model of Hegel's absolute, (...) and to demonstrate how the model fits the argument of Hegel's Logic. Application of this model provides a philosophical explanation of the senses in which Hegel's metaphysics is idealist; he argues that thought is absolute and comparable to God in other systems of metaphysics: thought is both self-determining and metaphysically prior to being.

This paper provides a detailed examination of Kit Fine’s sizeable contribution to the development of a neo‐Aristotelian alternative to standard mereology; I focus especially on the theory of ‘rigid’ and ‘variable embodiments’, as defended in Fine 1999. Section 2 briefly describes the system I call ‘standard mereology’. Section 3 lays out some of the main principles and consequences of Aristotle’s own mereology, in order to be able to compare Fine’s system with its historical precursor. Section 4 gives an exposition of (...) Fine’s theory of embodiments and goes on to isolate a number of potential concerns to which this account gives rise. In particular, I argue that Fine’s theory threatens to proliferate primitive sui generis relations of parthood and composition, whose characteristics must be stipulatively imposed on them, relative to particular domains; given its ‘superabundance’ of objects, Fine’s system far outstrips the already inflated ontological commitments of standard mereology; and there is a legitimate question as to why we should consider Fine’s primitive and sui generis relations of parthood and composition to be genuinely mereological at all, given their formal profile. These three objections lead me to conclude that we ought to explore other avenues that preserve the highly desirable, hylomorphic, features of Fine’s mereology, while avoiding its methodological and ontological excesses.

In his “Farewell to Substance: A Differentiated Leave-Taking”, Peter Simons reaches the provocative conclusion that the concept of substance, as it is employed by metaphysicians, has become obsolete, since in the end there may be nothing at all which answers to it. No harm is done, Simons allows, if we continue to retain an everyday notion of substance, as long as we are aware of the limitations of this practice: there is no reason in general to expect that what is (...) salient from our specifically human point of view will retain a special place in light of our most considered scientific and metaphysical theories of the world. In this paper, I argue that, contrary to Simons’ pessimistic outlook, the concept of substance continues to retain its importance for metaphysics. Among the primary explanatory roles played by the concept of substance in metaphysics is its use in designating certain kinds of entities as occupying a privileged position relative to a particular ontology. But disputes over substancehood can also target the criteria themselves relative to which an ontologically privileged position is awarded to certain taxonomic categories. In these uses, we see the concept of substance employed in an absolute, a relational and a comparative sense, to designate items as substances simpliciter, as the substances of something else, or as more or less deserving of substance status.

You are the kind of entity for whom things can be good or bad. This is one of the most important facts about you. It provides you with the grounds for taking a passionate interest in your own life, for you are deeply concerned that things should go well for you. Presumably, you also want to do well, but that may be in part because you think that doing well is good for you, and that your life would be impoverished (...) if you did not. But even if your interest in doing well is completely independent of any reference to your own condition, it probably depends on the thought that there are other entities, entities who are dependent upon you or affected by you, for whom things can be good or bad. It is only because there are entities like you, entities for whom things can be good or bad, that anything is important at all. If there were no entities for whom things can be good or bad, nothing would matter. (shrink)

Aristotelian ideas have in the past been applied with mixed fortunes to quantum mechanics. One of the most persistent criticisms is that Aristotle’s notions of potentiality and actuality are burdened with a teleological character long ago abandoned in the natural sciences. Recently this criticism has been met with a model of the actualization of quantum potentialities in light of Aristotle’s doctrine of ‘spontaneous events’. This presumably restores the nowadays acceptable idea of efficient causation in place of Aristotle’s original doctrine of (...) the ‘four causes’. In this article I challenge the model by arguing that when properly scrutinized Aristotle’s final cause poses no problems for an Aristotelian reading of quantum mechanics. Final causes in fact provide a better ontology for quantum mechanics than spontaneous causation. The idea of ‘spontaneity’ is unanalyzable and therefore of little use in quantum mechanics. In addition, it is ontologically sterile in the context of quantum measurement, as shown by a historical and conceptual review of the role of efficient causation in experimental physics. (shrink)

Ontological separation plays a key role in Aristotle’s metaphysical project: substances alone are ontologically χωριστόν. The standard view identifies Aristotelian ontological separation with ontological independence, so that ontological separation is a non-symmetric relation. I argue that there is strong textual evidence that Aristotle employs an asymmetric notion of separation in the Metaphysics—one that involves the dependence of other entities on the independent entity. I argue that this notion allows Aristotle to prevent the proliferation of substance-kinds and thus to secure the (...) unity of his metaphysical system. (shrink)

Frege argues that number is so unlike the things we accept as properties of external objects that it cannot be such a property. In particular, (1) number is arbitrary in a way that qualities are not, and (2) number is not predicated of its subjects in the way that qualities are. Most Aristotle scholars suppose either that Frege has refuted Aristotle's number theory or that Aristotle avoids Frege's objections by not making numbers properties of external objects. This has led some (...) to conclude that Aristotle's accounts of arithmetical and geometrical objects differ substantially. I close this supposed gap by showing that Aristotle's arithmetical objects, like geometrical objects, are just certain sensible things qua certain properties they in fact possess. Specifically, numbers are pluralities qua quantitative or relational properties like ten units or ten. I show that this view is resistant to the Fregean concerns about arbitrariness and numerical predication. (shrink)

The opening argument in the Metaphysics M.2 series targeting separate mathematical objects has been dismissed as flawed and half-hearted. Yet it makes a strong case for a point that is central to Aristotle’s broader critique of Platonist views: if we posit distinct substances to explain the properties of sensible objects, we become committed to an embarrassingly prodigious ontology. There is also something to be learned from the argument about Aristotle’s own criteria for a theory of mathematical objects. I hope to (...) persuade readers of Metaphysics M.2 that Aristotle is a more thoughtful critic than he is often taken to be. (shrink)

I argue in defense of Aristotle's position that contemplation is the proper use of at least some of one's leisure and that, consequently, leisure education must consist in teaching the inclination and capacity for contemplation. However, my position is somewhat more flexible than Aristotle's, in that I allow that there are other activities worthy of some leisure. My argument examines Aristotle's own comments on the importance of theoria as well as commentaries by Ackrill, Nagel, Broadie, Green and Telfer. In the (...) conclusion I argue that there are good reasons to think that studying Philosophy is one of the best strategies for leisure education. (shrink)

In many actual arguments, the conclusion seems intuitively to follow from the premisses, even though we cannot show that it follows logically. The traditional approach to evaluating such arguments is to suppose that they have an unstated premiss whose explicit addition will produce an argument where the conclusion does follow logically. But there are good reasons for doubting that people so frequently leave the premisses of their arguments unstated. The inclination to suppose that they do stems from the belief that (...) the only way in which an argument's conclusion can follow definitely from its premisses is to follow logically. I argue that this belief is mistaken. I propose a revision of the current generic conception of logical consequence, and its variant specifications, to avoid the paradoxes of strict implication. The revised conception can then be naturally extended to include also what we might call 'enthymematic consequence'. This concept is a kind of consequence, whose properties merit investigation.

The purpose of this paper is to build a parallelism between Aristotle’s debate with Plato on the merits of poetry and the debate of Hume with Smith on the nature of sympathy. My arguments is that the Aristotelian concept of pity, as presented in the Poetics, presupposes a mechanism of sympathy which is akin to the Smithian one, as articulated in his Theory of Moral Sentiments. Accordingly, I reconstruct Aristotle’s debate with Plato on poetry as a debate on the operation (...) and value of sympathy, and I trace an intriguing contiguity on the way Plato and Hume understood the mechanism of sympathy.

In this paper I argue that the basic form of good luck (eutuchia) that Aristotle identifies in his Eudemian Ethics 8.2 is the divine good luck, which is not also natural good luck, as is commonly assumed by interpreters. The property of being lucky is neither a primitive nor a natural property, nor such that it is based on some natural property, but a property bestowed by god. Hence, the only satisfactory explanation of good luck must be theological. Furthermore, I (...) argue that Aristotle’s account is neutral in regard to character, intellectual, and physical dispositions of those who are subject to good luck. (shrink)

Since Aristotle, many writers have treated metaphors and similes as equals: any metaphor can be paraphrased as a simile, and vice-versa. This property of metaphors is the basis for psycholinguistic comparison theories of metaphor comprehension. However, if metaphors cannot always be paraphrased as similes, then comparison theories must be abandoned. The different forms of a metaphor—the comparison and categorical forms—have different referents. In comparison form, the metaphor vehicle refers to the literal concept, e.g. 'in my lawyer is like a shark', (...) the term 'shark' refers to the literal fish. In categorical form, 'my lawyer is a shark', 'shark' refers to an abstract (metaphorical) category of predatory creatures. This difference in reference makes it possible for a metaphor and its corresponding simile to differ (a) in interpretability and (b) in meaning. Because a metaphor cannot always be understood in terms of its corresponding simile, we conclude that comparison theories of metaphor are fundamentally flawed. (shrink)

Priority monism is the doctrine that there is exactly one substance: the whole concrete cosmos. This paper develops an objection to priority monism. The objection is that although every substance is necessarily a substance, for the priority monist the cosmos is not necessarily a substance. It follows that the cosmos is not a substance and so priority monism is false. The priority monist's pluralist opponent, I argue, can avoid a parallel objection to her view.

Establishing Dispositionalism as a viable theory of modality requires the successful fulfilment of two tasks: showing that all modal truths can be derived from truths about actual powers, and offering a suitable metaphysics of powers. These two tasks are intertwined: difficulties in one can affect the chances of success in the other. In this paper, I generalise an objection to Dispositionalism by Jessica Leech and argue that the theory in its present form is ill-suited to account for de re truths (...) about merely possible entities. I argue that such difficulty is rooted in a problem in the metaphysics of powers. In particular, I contend that the well-known tension between two key principle of powers ontology, namely Directedness and Independence has received an unsatisfactory solution so far, and that it is this unsatisfactory solution concerning the status of “unmanifested manifestations” that makes it hard for Dispositionalism to account for mere possibilia. I develop a novel account of the status of unmanifested manifestations and an overall metaphysics of powers which allows to better respond to Leech's objection and handle mere possibilia. The central idea of the proposal is that unmanifested manifestations are akin to mere logical existents, and are best characterised as non-essentially non-located entities. (shrink)

The author of the Yogav sistha Mah r m yana has liberation (moksa) foremost on her or his mind and this focus appears to relegate virtue (dharma) to poor relation status. Yet, R ma's question to Vasistha is, 'How should one live in this world?' This signals a strongly ethical stance and opens another avenue of exploration; the possibility that the teachings on the realisation of liberation are concomitant with the teachings regarding the embodiment of virtue. The aim of this (...) paper is to flesh out the admittedly skeletal frame of virtue by comparing the theories in the Yogav sistha with Aristotle's elaboration of virtue in the Nicomachean Ethics. I argue that, in spite of fundamental metaphysical differences between the two philosophers, the stages of moral development described in the Yogav sistha harmonise with Aristotle's theories and provide insights into problems that arise in Aristotle's work.

This paper discusses Aristotle’s theory of reproduction: specifically, the good that he thinks organisms attain by reproducing. The aim of this paper is to refute the widespread theory that Aristotle believes plants and animals reproduce for the sake of attenuated immortality. This interpretive claim plays an important role in supporting one leading interpretation of Aristotle’s teleology: the theory that Aristotelian nature is teleologically oriented with a view solely to what benefits individual organisms, and what benefits the organism is its survival (...) and well–being. This paper challenges the theories that Aristotle takes plants and animals to reproduce for the sake of attenuated immortality, and that he believes survival to be the most basic of goods. It is argued that Aristotle believes reproduction is detrimental to organisms’ health and longevity but nonetheless is central to plant and animal flourishing. It is claimed that, to explain the fundamentality of the reproductive soul function, Aristotle appeals to the eternal and divine. (shrink)

In Aristotle's biological works, there is an apparent conflict between passages which seem to insist that only hypothetical necessity (anagk ex hypotheses) operates in the sublunary world, and passages in which some biological phenomena are explained as simply (hapls) necessary. Parallel to this textual problem lies the claim that explanations in terms of simple necessity render teleological explanations (in some of which Aristotle puts hypothetical necessity to use) superfluous. I argue that the textual conflict is only apparent, and that Aristotle's (...) notion of coincidental sameness allows him to avoid the superfluity problem. (shrink)

In Sophistical Refutations 8 Aristotle claims that every sophistical refutation depends on a false belief which is implicitly held by the victim of the fallacy and can normally be elicited from him as an explicit additional premiss. In this case the fallacious argument will be turned into a valid one, albeit with a false premiss. The paper discusses the nature of the FVP and tries to discover how it works when it tacitly causes the false appearance of a fallacious argument.

The goal of this article is to explore how a social justice framework can help illuminate the role that consent should play in health and science policy. In the first section, we set the stage for our inquiry with the important case of Henrietta Lacks. Without her knowledge or consent, or that of her family, Mrs. Lacks’s cells gave rise to an enormous advance in biomedical science—the first immortal human cell line, or HeLa cells.

We suggest that, far from establishing an inconsistency in the standard theory of the geometrical linear continuum, Zeno’s Paradox of Extension merely establishes an inconsistency between the standard theory of geometrical magnitude and a misguided system of length measurement. We further suggest that our resolution of Zeno’s paradox is superior to Adolf Grünbaum’s now standard resolution based on Lebesgue measure theory.

Once again it is becoming fashionable to ask ‘What character traits are virtues?’ Naturally, it behooves us to try to recapture the insights of our predecessors, as well as forging ahead on our own. In this paper I shall examine one such insight.

Aristotle’s 'Metaphysics' defends a number of theses about oneness ['to hen']. For interpreting the 'Metaphysics'’ positive henology, two such theses are especially important: 'to hen' and being ['to on'] are equally general and so intimately connected that there can be no science of the former which isn’t also a science of the latter, and to hen is the foundation ['archē'] of number qua number. Aristotle decisively commits himself to both and. The central goal of this article is to improve our (...) understanding of what the 'Metaphysics'’ endorsement of their conjunction amounts to. To this end we explore three manners of being one which enter into Aristotle’s 'Metaphysics': I call them 'unity, uniqueness', and 'unit-hood'. On the view the article defends, it’s unity that’s at issue in Aristotle’s endorsement of and unit-hood that’s at issue in his endorsement of. The 'Metaphysics'’ positive henology as whole, I suggest, is best interpreted by positing a theory-internal distinction between unity, uniqueness, and unit-hood. (shrink)

The pseudo-Aristotelian Mechanical Problems is the earliest known ancient Greek text on mechanics, principally concerned with the explanation of a variety of mechanical phenomena using a particular construal of the principle of the lever. In the introduction, the author (thought to be an early Peripatetic) quotes the tragic poet Antiphon to summarise a discussion of the techne-physis (art-nature) relationship and the status of mechanics as a techne. I argue that this citation of a poet is an Aristotelian cultural signature, intended (...) to guide its reader(s) towards a better understanding of the nature of mechanics as expounded in the Mechanical Problems. By analysing several instances where Aristotle cites Antiphon (as well as other tragic poets) in the Aristotelian corpus, I propose that both the author of the Mechanical Problems and Aristotle use poets for the purpose of persuasion. This is in turn explained by understanding the homologous relationship between mechanics-as-techne (according to the author of the Mechanical Problems) and poetics-as-techne (according to Aristotle) in terms of their shared status as poietike techne (productive art) and claims to universal knowledge. A final facet of the proposed relationship between mechanics and poetry is hypothesised on the grounds of their mimetic nature. (shrink)

Some of Aristotle’s statements about the indemonstrability of the Principle of Non-Contradiction (PNC) in Metaphysics Γ 4 merit more attention. The consensus seems to be that Aristotle provides two arguments against the demonstrability of the PNC, with one located in Γ 3 and the other found in the first paragraph of Γ 4. In this article, I argue that Aristotle also relies upon a third argument for the same conclusion: the argument from truth. Although Aristotle does not explicitly state this (...) argument, it is the best argument that he could use to defend some of his statements in the second paragraph of Γ 4. Since the argument relies on only a few of Aristotle’s core views about truth, I propose that it is faithful to his considered position throughout his corpus, and it may be the strongest argument he could offer for the indemonstrability of the PNC.

This paper focuses on Galen’s views about the formal cause against the wider background of his account of causation. In his works on the pulse, Galen provides an in-depth discussion of issues such as the theory of causes and the problem of definition. While Galen is inclined to incorporate Peripatetic doctrines and vocabulary, he neglects Aristotle’s formal cause both in his account of causes and in that of definition. Further parallels outside the corpus on the pulse confirm Galen’s reserved attitude (...) towards the (Peripatetic) formal cause. In his work That the Faculties of the Soul Follow the Mixtures of the Body, however, Galen refers favourably to the Peripatetic theory of hylomorphic form. More precisely, Galen equates the Peripatetic en-mattered form with the mixture of homoeomerous bodies (the ratio or proportion of the elementary qualities in them). Here I will attempt to provide an explanation of Galen’s mixed attitude towards the formal cause and I will argue that his general position is consistent after all. In addition to this, I will try to set Galen’s position against the background of the Peripatetic debates on the status of form. (shrink)

The paper analyses the argumentative structure of a difficult passage from Aristotle's Metaphysics XII 7 on the basis of a topos of sameness provided in Top. VII 1. In doing this the article gives an example of how Aristotle's treatises on dialectic can prove useful to understand what he says in his more philosophically committed writings. The article also shows how general argumentative techniques and more or less explicit specific philosophical assumptions interact in shaping Aristotle's arguments and how the distinction (...) of these different factors can help us have a better grasp on Aristotle's text.

When in classical formal logic the notions of deduction, valid inference and logical consequence are defined, causal language plays no role. The founder of western logic, Aristotle, identified ‘non-cause’, or ‘positing as cause what is not a cause’, as a logical fallacy. I argue that a systematic re-examination of Aristotle's analysis of NCF, and the related language of logical causality, in the Sophistical Refutations, Topics, Analytics and Rhetoric, helps us to understand his conception of. It reveals that Aristotle's syllogismhood is (...) non-monotonic, and thus narrower than classical validity as consisting in, or coextensive with, necessary truth-preservation. It also supports the conclusion that a syllogism is a form of relevant consequence: the premisses must be causes of the conclusion in the sense that they are not only sufficient but also necessary for the conclusion to follow. Close analysis of NCF also suggests that syllogistic relevance is not a semantic matter, but a syntactic.. (shrink)

A number of recent discussions of atheism allude to cosmological arguments in support of theism. The five ways of Aquinas are classic instances, offered as rational justification for theistic belief. However, the five ways receive short shrift. They are curtly dismissed as vacuous, arbitrary, and even insulting to reason. I contend that the atheistic critique of the Thomistic five ways, and similarly formulated cosmological arguments, argues at cross purposes because it misrepresents them. I first lay out the context, intent and (...) structure of Aquinas’ arguments, then show in what way recent discussions misrepresent them, and finally conclude with a comment on metaphysical orientation, which I take to be central, not only to a proper understanding of the Thomistic five ways but generally to the debate between atheism and theism on the existence of God.
