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.

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.

A methodological statement that occurs at Nicomachean Ethics vii 1 and its implementation in the subsequent discussion has widely been called ‘the method of endoxa’. According to the received interpretation, this method follows some strict steps and epitomizes the dialectical method of inquiry. I question the received interpretation and argue for a deflationary and non-dialectical account which, I believe, conforms with Aristotle’s scientifically oriented general methodology.

What role, if any, does dialectic play in Aristotle’s epistemology in the Topics? In this paper I argue that it does play a role, but a role that is independent of endoxa. In the first section, I sketch the case for thinking that dialectic plays a distinctively epistemological role—not just a methodological role, or a merely instrumental role in getting episteme. In the second section, I consider three ways it could play that role, on two of which endoxa play at (...) least a co-starring role. But in the third section, I argue that endoxa don’t play that co-starring role, by arguing for a deflationary account of what endoxa are. For that reason, the third view emerges as the most plausible; but the third view is, I’ll suggest, Platonic. (shrink)

Plato’s demiurge makes a series of questionable decisions in creating the world. Most notoriously, he endeavors to replicate, to the extent possible, some of the features that his model possesses just insofar as it is a Form. This has provoked the colorful complaint that the demiurge is as raving mad as a general contractor who constructs a house of vellum to better realize the architect’s vellum plans (Keyt 1971). The present paper considers the sanity of the demiurge’s reasoning in light (...) of Timaeus 32c5-33b1, where he invokes considerations of wholeness, completeness, uniqueness, and eternality in deciding to build the body of the world from all of each of the simple bodies. Since the passage makes no appeal to the demiurge’s intelligible model, one can mine it for indications of the value that the demiurge takes those features to have independent of mimetic goals. I argue that, for Plato, those features are intrinsically good-making and, thus, that it is not only appropriate for them to characterize Forms qua Forms but also that it is appropriate for the demiurge to aim at replicating them, to the extent possible, in his creation. In particular, I argue that the demiurge’s success in instilling a circumscribed version of each feature in his creation helps to qualify it as a genuine being despite the fact that it comes to be.

This paper discusses the fallacies of combination and division as they are presented by Aristotle in chapter 4 of his Sophistici Elenchi. Aristotle's examples are concise, their discussion is unclear, and it is difficult to distinguish the cases of combination from those of division. I analyse the Aristotelian examples and the interpretations offered so far. I show that these interpretations suffer from a major defect: they fail to identify a common characteristic whereby the Aristotelian examples can be classified as instances (...) of combination or division. In my reconstruction of the examples, I repair this deficiency: I give a single pattern of explanation for the fallacy of combination and another (similar) pattern for the fallacy of division. Thus, it is possible to free Aristotle from the following charges: (i) he did not clearly distinguish between combination and division, and (ii) he reduced combination and division to a single fallacy. My explanation of the fallacies uses the notion of scope of an expression: in modern terminology, the fallacy of combination can be described as ?fallacy of the wide scope?, the fallacy of division as ?fallacy of the narrow scope?

Roger T. Ames's A Sourcebook in Classical Confucian Philosophy is a companion volume to his Conceptual Lexicon for Classical Confucian Philosophy. It includes texts in the original classical Chinese along with their translations, allowing experts and novices alike to make whatever comparisons they choose. In applying a method of comparative cultural hermeneutics, Ames has tried to let the tradition speak on its own terms. The goal is to encourage readers to move between the translated text and commentary, the philosophical introduction (...) that attempts to sensitize them to the interpretative context, and the companion Lexicon of key philosophical terms, with the expectation that in the fullness of time they will be able to appropriate the original Chinese terminologies themselves. Armed with their own increasingly robust insight into these philosophical terms, readers will be able to carry this nuanced understanding over into their critical reading of other available translations. Ultimately, for students who would understand Chinese philosophy, tian 天 must be understood as tian 天, and dao 道 must be dao 道. (shrink)

The quarrel between Plato and the poets in the Utopia and try to exclude them from there is a very important subject in the Republic. He in the book III explains the limits for poems and determines the poems that can be read for youths and the poems that cannot be read for them. This radical Platonic approach to the poets and their poems can be linked today to the many different media especially TV and its programs. In Plato's view, (...) our reaction to the different events in the everyday life is a copy of our reaction to the poem. This problem is today linked to the TV and other social media like cinema. TV in only an instrument for distribution and transmission, and does not present any new method for interpreting reality. In another word, TV only present reality as it is and TV is like the Platonic poet in this respect. We can recite the Platonic objection on poem, also on the TV and its functions. In the present article we will try to survey the nature and the functions of TV by the Platonic method of critiquing poets in the Utopia. (shrink)

The pseudo-Platonic Definitions seems to ascribe to ὄνοµα, ‘name’, the function of signifying two kinds of predicate. This is problematic, and I propose an emendation of the text, arguing that a definition of ῥῆµα, ‘verb’, has fallen out.

The nature and value of autonomy has long been debated in diverse philosophical traditions, including moral and political philosophy. Although the notion dates back to ancient Greek philosophy, it was during the Age of Enlightenment that autonomy drew much attention. Thus, as may be known, moral philosophers tended to emphasize self-regulation, particularly one’s own will to abide by universal moral laws, as the term “autonomy” originates from the Greek words “self” (auto) and “rule” (nomos). In parallel, modern epistemologists supposedly espoused (...) the idea of intellectual autonomy as self-reliance. In this classical view, an intellectually autonomous explorer of knowledge must not depend on a belief that is obtained from another’s testimony, until one can justify it to oneself. However, accompanying the growing focus on the importance of social dimensions of acquiring knowledge and understanding, recent epistemologists have doubted the classical view and have since reconsidered intellectual autonomy from distinct approaches such as social and virtue epistemology. This paper propounds an interpersonal-epistemic approach to intellectual autonomy. First, it is argued that thinking through questioning both individually and with other epistemic peers is an interpersonal-epistemic practice. Second, it is demonstrated that with particular cognitive features inherent within us, an intellectually autonomous person must think through questioning in necessary situations. This interpersonal account of intellectual autonomy can conceptually enrich intellectual autonomy by considering its relationship with not only responsibility but also with vulnerability. Specifically, regarding responsibility, an intellectually autonomous person must be responsible for his or her own actions throughout questioning processes. Regarding vulnerability, our intellectual autonomy lies in retaining autonomy with vulnerability in the plastic control of the questioning processes. (shrink)

Aristotle talks about 'the first philosophy' throughout the Metaphysics – and it is metaphysics that Aristotle considers to be the first philosophy – but he never makes it entirely clear what first philosophy consists of. What he does make clear is that the first philosophy is not to be understood as a collection of topics that should be studied in advance of any other topics. In fact, Aristotle seems to have thought that the topics of Metaphysics are to be studied (...) after those in Physics. In what sense could metaphysics be the first philosophy in the context of contemporary metaphysics? This is the question examined in this essay. Contemporary topics such as fundamentality, grounding, and ontological dependence are considered as possible ways to understand the idea of first philosophy, but I will argue that the best way to understand it is in terms of essence.

An age-old proposal that to be is to be a unity, or what I call a grouping, is updated and applied to the question “Why is there something rather than nothing?” (WSRTN). I propose the straight-forward idea that a thing exists if it is a grouping which ties zero or more things together into a new unit whole and existent entity. A grouping is visually manifested as the surface, or boundary, of the thing. In regard to WSRTN, when we subtract (...) away all existent entities, the resulting "nothing" is the entirety, the all. That “nothing is the complete definition of the situation. An entirety/all is a grouping, meaning that “nothing” is itself an existent entity. One objection might be that being a grouping is a property so how can it be there in "nothing"? The answer is that it is only once all known existent entities, including all properties and the mind visualizing this, are removed does this “nothing” gain the entirety/all grouping property. Therefore, the very lack of all existent entities is itself what allows this new property to be present and thereby to allow "nothing" to be an existent entity. This entirety/all grouping property is inherent, or intrinsic, to “nothing” and cannot be removed to get a more pure “nothing”. While the ideas that “nothing” is a “something” that exists necessarily isn’t new, the grouping, or any, mechanism for how this can be so is. (shrink)

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.

EXPANDED EDITION (eBook): -/- Infinity Is Not What It Seems...Infinity is commonly assumed to be a logical concept, reliable for conducting mathematics, describing the Universe, and understanding the divine. Most of us are educated to take for granted that there exist infinite sets of numbers, that lines contain an infinite number of points, that space is infinite in expanse, that time has an infinite succession of events, that possibilities are infinite in quantity, and over half of the world’s population believes (...) in a divine Creator infinite in knowledge, power, and benevolence. -/- According to this treatise, such assumptions are mistaken. In reality, to be is to be finite. The implications of this assessment are profound: the Universe and even God must necessarily be finite. -/- The author makes a compelling case against infinity, refuting its most prominent advocates. Any defense of the infinite will find it challenging to answer the arguments laid out in this book. But regardless of the reader’s position, FOREVER FINITE offers plenty of thought-provoking material for anyone interested in the subject of infinity from the perspectives of philosophy, mathematics, science, and theology. -/- This electronic edition of FOREVER FINITE is offered free online for all and is expanded with content that does not appear in the published edition due to print production page limitations. From the Introduction to the Conclusion, Chapters 1–27 are identical to the published print edition, including the page numbering for the chapters. This electronic edition adds an appendix and associated content—specifically, updates to the book’s back matter (68 new endnotes, 17 new bibliographic references, 3 new figure credits, 14 new glossary terms) and front matter (an updated table of contents and this preface note).

One may distinguish between three broad conceptions of linguistic meaning. One conception, which I will call “logical”, views meaning as given in reference (for words) and truth (for sentences). Another conception, the “monological” one, seeks meaning in the cognitive capacities of the single mind. A third, “dialogical”, conception attributes meaning to interaction between individuals and personal perspectives. In this chapter I directly contrast how well these three approaches deal with the evidence brought forth by fictive interaction. I examine instances of (...) fictive interaction and argue that intersubjectivity in these instances cannot be reduced to either referential-logical or individual-cognitive semantic notions. It follows that intersubjectivity must belong to the essence of linguistic meaning. (shrink)

This article is an extended analysis of the most recent scholarly work on Locke's account of sensitive knowledge. Lex Newman's "dual cognitive relations" model of sensitive knowledge is examined in detail. The author argues that the dual cognitive relations model needs to be revised on both philosophical and historical grounds. While no attempt is made to defend Locke's position, the aim is to show that it is at least consistent, contrary to the received view. The final section provides textual support (...) for the interpretation. (shrink)

Do facts about what an agent would freely do in certain circumstances at least partly determine any of her moral obligations? Actualists answer ‘yes’, while possibilists answer ‘no’. We defend two novel hybrid accounts that are alternatives to actualism and possibilism: Dual Obligations Hybridism and Single Obligation Hybridism. By positing two moral ‘oughts’, each account retains the benefits of actualism and possibilism, yet is immune from the prima facie problems that face actualism and possibilism. We conclude by highlighting one substantive (...) difference between our two hybrid accounts. (shrink)

Aristotle’s modal syllogistic is his study of patterns of reasoning about necessity and possibility. Many scholars think the modal syllogistic is incoherent, a ‘realm of darkness’. Others think it is coherent, but devise complicated formal modellings to mimic Aristotle’s results. This volume provides a simple interpretation of Aristotle’s modal syllogistic using standard predicate logic. Rini distinguishes between red terms, such as ‘horse’, ‘plant’ or ‘man’, which name things in virtue of features those things must have, and green terms, such as (...) ‘moving’, which name things in virtue of their non-necessary features. By applying this distinction to the Prior Analytics, Rini shows how traditional interpretive puzzles about the modal syllogistic melt away and the simple structure of Aristotle’s own proofs is revealed. The result is an applied logic which provides needed links between Aristotle’s views of science and logical demonstration. The volume is particularly valuable to researchers and students of the history of logic, Aristotle’s theory of modality, and the philosophy of logic in general. (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)

This article explores Spinoza's distinctive contribution to the eudaimonistic tradition, which considers happiness (eudaimonia) to be the highest good. Most (if not all) ancient eudaimonists endorse some sort of hierarchy between mind and body, where one is always dependent on, or subordinate to, the other. In particular, many of them endorse ethical intellectualism, where mental things are considered more valuable than bodily ones. I argue that Spinoza, in contrast, considers mind and body ontologically and ethically identical and equal, thereby bringing (...) something new to this ethical tradition. (shrink)

Diachronic emergence has recently been characterised as transformation. This aims to capture the thought that the entities that emerge are radically new or different. Transformation is hence closely linked with a central (but rarely raised) challenge for all emergentists: how to account for the identity and individuation of entities involved in emergence. With this challenge in view, I develop and probe four interpretations of transformation: addition, replacement, fusion, and transubstantiation. Of those, transubstantiation provides the most plausible response to the challenge (...) about identity. Accordingly, diachronic emergence is a transformative process whereby an individual passes from one primary kind to another. (shrink)

Using the Aristotelian virtue of friendship and concept of practical wisdom, this paper argues that engaging in political discourse with friends on social media is conducive to the pursuit of the good life because it facilitates the acquisition of the socio-political information and understanding necessary to live well. Previous work on social media, the virtues, and friendship focuses on the initiation and maintenance of the highest form of friendship (Aristotle’s ‘ideal friendship’) online. I argue that the information necessary to live (...) well can come from non-ideal, civic friends in addition to ideal friends. In order to acquire this information successfully via social media, users should practice inclusive engagement, self-control, discretion, and audience-sensitivity in their cyber interactions. This argument is salient given the current concerns about ‘echo chambers’ or ‘filter bubbles’, in which users ignore or block out friends and news sources that support political perspectives different from one’s own.

We provide a new interpretation of Zeno’s Paradox of Measure that begins by giving a substantive account, drawn from Aristotle’s text, of the fact that points lack magnitude. The main elements of this account are (1) the Axiom of Archimedes which states that there are no infinitesimal magnitudes, and (2) the principle that all assignments of magnitude, or lack thereof, must be grounded in the magnitude of line segments, the primary objects to which the notion of linear magnitude applies. Armed (...) with this account, we are ineluctably driven to introduce a highly constructive notion of (outer) measure based exclusively on the total magnitude of potentially infinite collections of line segments. The Paradox of Measure then consists in the proof that every finite or potentially infinite collection of points lacks magnitude with respect to this notion of measure. We observe that the Paradox of Measure, thus understood, troubled analysts into the 1880’s, despite their knowledge that the linear continuum is uncountable. The Paradox was ultimately resolved by Borel in his thesis of 1893, as a corollary to his celebrated result that every countable open cover of a closed line segment has a finite sub-cover, a result he later called the “First Fundamental Theorem of Measure Theory.” This achievement of Borel has not been sufficiently appreciated. We conclude with a metamathematical analysis of the resolution of the paradox made possible by recent results in reverse mathematics. (shrink)

Fragments of Aristotle’s lost Protrepticus seem to offer inconsistent arguments for the value of contemplation (one argument appealing to contemplation's uselessness, the other appealing to its utility). In this paper, I argue that these arguments are mutually consistent. Further, I argue that, contrary to first appearances, Aristotle has resources in the Protrepticus for explaining how contemplation, even if it has divine objects, can nevertheless be useful in the way in which he claims, viz., for providing cognitive access to boundary markers (...) (horoi) of the human good. (shrink)

In fragments from the Protrepticus, Aristotle offers three linked arguments for the view that philosophy is easy. According to an obvious normative worry, however, Aristotle also seems to think that the easiness of many activities has little to do with their choiceworthiness. Hence, if the Protrepticus seeks to exhort its audience to philosophize on the basis of philosophy’s easiness, then perhaps the Protrepticus provides the wrong sort of hortatory appeal. In response, I briefly situate Aristotle’s arguments in their dialectical context. (...) On this basis, I elucidate what sort of easiness Aristotle attributes to philosophy, and what difference Aristotle thinks philosophy’s easiness makes to its choiceworthiness. (shrink)

I examine Zhu Xi's investigation thesis, the claim that a necessary condition (in ordinary cases) for one’s acting fully virtuously is one’s investigating the all-pervasive pattern in things (gewu格物). I identify four key objections that the thesis faces, which I label the rationalism, elitism, demandingness, and irrelevance worries. Zhu Xi, I argue, has resources for responding to each of these worries, and for defending a broadly intellectualist conception of fully virtuous agency.

In Nicomachean Ethics X.7–8, Aristotle defends a striking view about the good for human beings. According to Aristotle, the single happiest way of life is organized around philosophical contemplation. According to the narrowness worry, however, Aristotle's contemplative ideal is unduly Procrustean, restrictive, inflexible, and oblivious of human diversity. In this paper, I argue that Aristotle has resources for responding to the narrowness worry, and that his contemplative ideal can take due account of human diversity.

RésuméLa philosophie de Spinoza est souvent célébrée pour son fort courant anti-normatif. Spinoza soutient, par exemple, que le bien et le mal n'indiquent rien de positif dans les choses, et que les affects sont toujours particuliers à la situation dans laquelle ils surviennent. Et pourtant, Spinoza soutient que la mélancolie est « toujours mauvaise » et la gaieté « toujours bonne », problématisant ainsi un principe métaphysique clé de son système. Prêtant attention à certaines sections de l’Éthique et du Traité (...) théologico-politique, cet article offre une lecture de ces deux affects problématiques, avant d’établir un lien entre Spinoza et des travaux récents sur la mélancolie aux débuts de l’époque moderne, qui la conceptualisent comme un « assemblage ».

In recent years, many philosophers of science have attempted to articulate a theory of non-epistemic emergence that is compatible with mechanistic explanation and incompatible with reductionism. The 2005 account of Fred C. Boogerd et al. has been particularly influential. They argued that a systemic property was emergent if it could not be predicted from the behaviour of less complex systems. Here, I argue that Boogerd et al.'s attempt to ground emergence in complexity guarantees that we will see emergence, but at (...) the cost of rendering it either trivial or epistemic. There are three basic problems. First, neither the measures of complexity explicitly mentioned by Boogerd et al. nor the most popular measures in the literature can do the practical and theoretical work that they assign to complexity. Second, I argue that while the success of their view depends on restricting the base of information available to the reductionist, this cannot be done in a way that is metaphysically neutral with respect to emer..

What is a natural kind? As we shall see, the concept of a natural kind has a long history. Many of the interesting doctrines can be detected in Aristotle, were revived by Locke and Leibniz, and have again become fashionable in recent years. Equally there has been agreement about certain paradigm examples: the kinds oak, stickleback and gold are natural kinds, and the kinds table, nation and banknote are not. Sadly agreement does not extend much further. It is impossible to (...) discover a single consistent doctrine in the literature, and different discussions focus on different doctrines without writers or readers being aware of the fact. In this paper I shall attempt to find a defensible distinction between natural and non-natural kinds. (shrink)

This paper draws on Claudia Card’s discussions of moral luck to consider the complicated moral life of people—described as pessimists—who accept the heavy knowledge of the predictability of the bad moral luck of oppression. The potential threat to ethics posed by this knowledge can be overcome by the pessimist whose resistance to oppression, even in the absence of hope, expresses a sense of still having a ‘‘claim’’ on flourishing despite its unattainability under oppression.

In the eighth chapter of De Sophisticis Elenchis, Aristotle introduces a mode of sophistical refutation that constitutes an addition to the taxonomy of the earlier chapters of the treatise. The new mode is pseudo-scientific refutation, or “the [syllogism or refutation] which though real, [merely] appears appropriate to the subject matter”. Against the grain of its most commonly accepted reading, I argue that Aristotle is not concerned in SE 8 to establish that both the apparent refutations of SE 4–7 and pseudo-scientific (...) refutations issue in false conclusions. His concern rather is to provide a causal analysis of both classes of apparent refutation alike which will explain why both kinds of apparent refutation are sophistical – and whose solutions are therefore the task of no special science but of a dialectical σλλογιστιϰή τέχνη. I conclude my analysis with the observation that Aristotle exploits the results of SE 8 to fend off inSE 9, 10, and 11 respectively a triad of threats to the very existence of a τέχνη of the resolution of sophistical refutation. The three threats are: the impossibility of omniscience; the relativity of semantic beliefs; and the incapacity of a questioner ignorant of a science to expose the ignorance of a pretender to scientific expertise.

In recent decades, the logical study of rational belief dynamics has played an increasingly important role in philosophy. However, the dynamics of concepts such as conceptual learning received comparatively little attention within this debate. This is problematic insofar as the occurrence of conceptual change (especially in the sciences) has been an influential argument against a merely logical analysis of beliefs. Especially Kuhn’s ideas about the incommensurability, i.e., untranslatability, of succeeding theories seem to stand in the way of logical reconstruction. This (...) paper investigates conceptual change as model-changing operations similar to belief revision and relates it to the notion of incommensurability. I consider several versions of conceptual change and discuss their influences on the expressive power, translatability and the potential arising of incommensurability. The paper concludes with a discussion of animal taxonomy in Aristotle’s and Linnaeus’s work. (shrink)
