This book is a thesis submitted to the Faculty of Arts of the University of Utrecht. It was prepared under the supervision of Prof. Dr. H. Schultink. I would like to express my gratitude to him for his criticisms of earlier versions which led to many improvements, in particular with respect to the exposition of the argument. To my co-referent Dirk van Dalen, reader in the Department of Philo sophy (,Centrale Interfaculteit') of the University of Utrecht, I am (...) greatly indebted for his valuable and fruitful suggestions about problems relevant to both linguistics and logic. Several ideas developed in this study owe their present concrete form to our many discussions. This thesis originates in syntactic research into the Aspects carried out in 1967 under the supervision of Albert Kraak, professor at the University of Nijmegen, who ever since gave much attention to my work in progress. I am very grateful to him for his careful and stimulating criticism as well as for the continuous support he gave me during these years. The present study closely relates to the work of my colleague Wim Klooster with regard to both its theoretical framework and its subject matter. Our joint work on the measurement of duration in Dutch is an integral part of the argument. I have greatly profited from the numerous discussions we have had. (shrink)

This paper presents a formalization of the classical proof of completeness in Henkin-style developed by Troelstra and van Dalen for intuitionistic logic with respect to Kripke models. The completeness proof incorporates their insights in a fresh and elegant manner that is better suited for mechanization. We discuss details of our implementation in the Lean theorem prover with emphasis on the prime extension lemma and construction of the canonical model. Our implementation is restricted to a system of intuitionistic propositional logic (...) with implication, conjunction, disjunction, and falsity given in terms of a Hilbert-style axiomatization. As far as we know, our implementation is the first verified Henkin-style proof of completeness for intuitionistic logic following Troelstra and van Dalen's method in the literature. (shrink)

How should we account for the contextual variability of knowledge claims? Many philosophers favour an invariantist account on which such contextual variability is due entirely to pragmatic factors, leaving no interesting context-sensitivity in the semantic meaning of ‘know that.’ I reject this invariantist division of labor by arguing that pragmatic invariantists have no principled account of embedded occurrences of ‘S knows/doesn’t know that p’: Occurrences embedded within larger linguistic constructions such as conditional sentences, attitude verbs, expressions of probability, comparatives, and (...) many others, I argue, give rise to a threefold problem of embedded implicatures.

This has been available under Teaching Materials, but items in that category are not easily located, so I have added it here. This short dialogue can be used to introduce students to the core claims of Stoic moral philosophy and to position Stoic moral philosophy in relation to its ancient alternatives: Cynicism, Epicureanism, and Peripatetic thought. The dialogue form is meant to make this fun and easy. -/- This little dialogue may also be of interest to readers who have encountered (...) various popular books on "How to Stoic". Such readers should know that Stoicism is a school of _philosophy_. The Stoics themselves would not recommend that you try to Stoic Yourself unless and until you were convinced of the _truth_ of the central claims of the school -- a truth that the ancient Stoics sought to establish by _arguments_. To treat Stoicism simply as self-help, without due regard to whether its central claims can be shown to be true, would be to treat those ancient philosophers with contempt. (shrink)

‘Know-that’, like so many natural language expressions, exhibits patterns of use that provide evidence for its context-sensitivity. A popular family of views – call it prag- matic invariantism – attempts to explain the shifty patterns by appeal to a pragmatic thesis: while the semantic meaning of ‘know-that’ is stable across all contexts of use, sentences of the form ‘S knows [doesn’t know] that p’ can be used to communicate a pragmatic content that depends on the context of use. In this (...) paper, the author argues that pragmatic invariantism makes inaccurate predictions for a wide range of well- known use data and is committed to attributing systematic pragmatic error to ordinary speakers. But pragmatic error is unprecedented, and it is doubtful that speakers are systematically wrong about what they intend to communicate. (shrink)

Surveys the ideals of friendship in ancient Greco-Roman philosophy. The notion of the best friendship inevitably reflects the various conceptions of a good life.

In previous chapters, it has become clear that Proclus’ metaphysics is often relevant to human life. In this chapter, that relation is elaborated on in detail, starting from the notion of a ‘textual community’. In the first section, the author presents the Neoplatonic goal of human life, assimilation to the divine. In the second section, he elaborates the scale of virtues through which, according to Proclus, one may reach that assimilation. The third section is devoted to establishing the interesting hypothesis (...) that the philosophical curriculum was in fact considered a mystagogy, aimed at internalizing semantic associations and thereby acquiring the different virtues. In the last section the author turns to Proclus’ political philosophy, and specifically the analogical relation between the philosopher-ruler and the demiurge. (shrink)

The Platonic dialogues contain passages that seem to point in quite opposite directions on the question of the moral equality of women with men. Rep. V defends the view that sexual difference need not be relevant to a person’s capacity for philosophy and thus for virtue. Tim. 42a-c, however, makes incarnation in a female body a punishment for failure to master the challenges of embodiment. This paper examines the different ways in which two subsequent Platonists, Proclus (d. 485 CE) and (...) Theodore of Asine (d. c. 360 CE), dealt with this tension. (shrink)

Plato's Tim. 90b1-c6 describes a pathway to the soul's salvation via the study of the heavens. This paper poses three questions about this theme in Platonism: 1. The epistemological question: How is the paradigmatic function of the visible heavenly bodies to be reconciled with various Platonic misgivings about the faculty of perception? 2. The metaphysical question: How can »assimilation« to the motions of bodies in the realm of Becoming provide for the salvation of souls when souls are »higher«- a mid-point (...) between Being and Becoming? 3. The psychological question: What can it mean for an incorporeal soul to utilise the motions of a body for an ethical and cognitive paradigm? And provides an account of how Proclus and some of his fellow Neoplatonists answered these questions. (shrink)

In dit artikel wordt de dominante metafysische oriëntatie in de hedendaagse meta-ethiek kritisch onder de loep genomen. Het hedendaagse debat, dat zich voornamelijk richt op de vraag hoe moraliteit metafysisch gezien 'in de werkelijkheid past', wordt gekenmerkt door een reeks complexe en soms esoterische discussies die, zo wordt betoogd, weinig bijdragen aan ons filosofische begrip van ethiek. Deze focus op metafysische grondslagen heeft geleid tot een tunnelvisie, waarin het debat gevangen zit tussen steeds ingewikkeldere vormen van non-cognitivisme, herconceptualisaties van 'objectiviteit' (...) en metafysische acrobatiek. Als alternatief wordt voorgesteld de aandacht in de meta-ethiek te verleggen naar het domein van praktisch redeneren. Door ons te concentreren op de patronen van geldige praktische argumentatie en het soort overwegingen dat mensen daadwerkelijk overtuigt, kunnen we wellicht een beter inzicht krijgen in de aard van ethische normativiteit en de rol ervan in ons leven. Het artikel pleit voor een meer pragmatische en minder metafysisch beladen benadering van de meta-ethiek, die zich richt op de daadwerkelijke praktijken van moreel redeneren en argumenteren.

Later versions of Platonic ethics fit the frame of eudaimonism and specify a telos based on Theaetetus 176B and Timaeus 90A-D: 'likeness to god in so far as possible'. This paper examines the development of this idea from the middle Platonist Alcinous to the Neoplatonist Proclus. It examines the way in which Proclus makes this specification of human happiness a bit less "other worldy".

In this paper we look at two kinds of relations that give rise to reasons for action of a distinctive sort: friendship and erotic love. We argue that what is common to these different relations of affection is that the people in them exhibit dispositions toward mutual direction by one another and interpretation of one another (in a sense that we describe in detail below). This mutual responsiveness is, in part, a matter of responding to reasons that arise from the (...) relation of love or friendship. These reasons are frequently distinct from – and may be opposed to – normative reasons arising from prudence or even morality. Yet reasons of love are normative: they too may obligate us. They may make demands on us that conflict with our present desires and require considerable sacrifice. (shrink)

The idea that there is a coherent and morally relevant concept of sexual perversions has been increasingly called into question. In what follows, I will be concerned with two recent attacks on the notion of sexual perversion: those of Graham Priest and Igor Primoratz. Priest’s paper is the deeper of the two. Primoratz goes methodically through various accounts of sexual perversion and finds difficulties in them. This is no small task, of course, but unlike Priest he does not attempt to (...) provide any diagnosis of why any attempt to analyse the concept of sexual perversion must fail. Priest argues that sexual perversion is an “inapplicable concept”: the presuppositions that would allow us to make sense of the notion have been rightly rejected. Without the theoretical backdrop of an Aristotelian moral teleology, we cannot provide a satisfactory account of sexual perversion, for only such a teleological world-view allows us to give some sense to the idea that a sexual practice might be morally wrong because it is unnatural. Priest surveys accounts of perversion that don’t appeal to any idea of unnaturalness and rejects them—rightly I believe. But, Priest argues, Aristotle’s own moral teleology is part and parcel of his wider views about purpose in nature. This natural teleology has been shown to be explanatorily superfluous. Though some sciences still talk of functions, this can be understood in terms of contributions to evolutionary survival. Though there is considerable disagreement about the details of the right account of function, all versions of this scientifically respectable teleology are morally neutral: it would not follow from the fact that homosexual intercourse does nothing to propagate the agents’ genetic material to future generations that it is therefore morally wrong. Here too I think Priest is right. He also considers what he calls “Aristotelian revivalism” in Roger Scruton’s account of sexual perversion. I think Priest sells Aristotelianism short. I have no interest in defending Scruton’s own understanding of the Aristotelian moral framework nor his particular account of sexual perversion. I shall, however, argue that Aristotelian moral philosophy provides a more useful framework for thinking about these issues than Priest implies, and attempt to defend an account of sexual perversion within the context of this framework.

This third and final volume concludes Hermias' commentary on Plato's Phaedrus. Here, Plato delivers a celebrated critique of writing, and its relationship to orality. Hermias follows him, and adds a general account of good writing. In addition, this volume offers the first English translation of the brief Introduction to Hermogenes' On Styles, which manuscripts attribute-probably mistakenly-to Hermias' teacher Syrianus. Baltzly and Share discuss the Introduction's authorship and its relation to the genuine commentaries of Syrianus on the rhetorical treatises of Hermogenes. (...) They illuminate the relationship between philosophy and rhetoric in the Neoplatonic schools, and provide a novel explanation of Neoplatonic commentaries as performances of Platonic literacy in ancient elite education. This translation offers novel evidence of interest for students of ancient philosophy, rhetorical education, and literature more broadly. It is accompanied by explanatory notes, an introduction, and scholarly apparatus, including indices, glossaries, and bibliography. (shrink)

Plato’s Phaedrus is a dialogue of journeys, a tale of transitions. It begins with Socrates’ question, ‘Where to and from whence, my dear Phaedrus?’ and concludes with the Socrates’ decision, ‘Let’s go’ (sc. back into the city from whence they’ve come). In the speech that forms its centre-piece Socrates narrates another famous journey—the descent of the soul into the body and its reascent to the realm of Forms through erotic madness. It is not too implausible to suppose that Plato himself (...) saw fit to relate his powerful images of the human soul’s fall and re-ascent by dramatic means that highlight the movement from one place to another. This explains how Hermias of Alexandria -- author of the longest sustained work on the Phaedrus to survive from antiquity related the physical journey to the Ilissus to the soul's descent and ascent. This seemingly implausible allegorising gains a certain kind of sense when we consider that the Neoplatonic commentary tradition formed part of a philosophic way of life with an ethical telos.

The author puts forward and defends a new argument for indirect realism called the argument from pain. The argument is akin to a well-known traditional argument to the same end, the argument from hallucination. Like the latter, it contains one premise stating an analogy between veridical perceptions and certain other states and one premise stating that those states are states of acquaintance with sense-data. The crucial difference is that the states that are said to be analogous to veridical perceptions are (...) pain-states instead of hallucinations. This difference makes the argument from pain immune to the standard objections against the argument from hallucination. (shrink)

In Plato’s dialogues we often find Socrates talking at length about poetry. Sometimes he proposes censorship of certain works because what they say is false or harmful. Other times we find him interpreting the poets or rejecting potential interpretations of them. This raises the question of whether there is any consistent account to be given of Socrates’ practice as a literary critic. One might think that Plato himself in the Ion answers the question that I have raised. Rhapsody, at least (...) in the Ion , is portrayed as the activity of interpreting and evaluating the works of the poets. At first glance at least, Plato seems to conclude that this activity cannot meet the standards of a τέχνη. Rhapsodes are divine madmen. Thus, there cannot be a systematic Platonic account of literary criticism because this activity is inherently irrational and, subsequently, not something that one could engage in in a systematic way, guided by a theory of any sort. In the first part of the paper I argue that the Ion does not simply consign the Interpretation of poetry to the irrational and, as a result, does not pose an obstacle to the possibility of a Platonic literary criticism. In the second part of the paper I turn to the task of finding an account of the purpose of reading poetry and strategies for fulfilling this purpose that make systematic sense of Socrates’ multifarious remarks about poetry.

It is widely supposed that Epicurus' identification of aponia (painlessness) and the absence of anxiety (ataraxia) yields as a consequence the claim that the most pleasant life is one that requires little in the way of resources or power. This paper argues that the remarks in Cicero which attempt to reconstruct Epicurus' reasons for thinking that aponia and ataraxia are the limit of pleasure are best interpreted if we suppose that the inference runs the other direction. Epicurus supposed that it (...) was a pre-theoretical constraint on any account of human happiness that it should be natural. Moreover, its naturalness means its in-principle availability to most humans. (shrink)

This essay surveys the main objections to aesthetic hedonism, the view that aesthetic value is reducible to the value of aesthetic pleasure or experience. Hedonism is the dominant view of aesthetic value, but a spate of recent criticisms has drawn its accuracy into question. I introduce some distinctions crucial to the criticisms, before using the bulk of the essay to identify and review six major lines of argument that hedonism's critics have employed against it. Whether or not these arguments suffice (...) to refute hedonism decisively, I argue that its privileged status, as the sole contender in aesthetic value theory, is detrimental to downstream research on aesthetic phenomena. The essay concludes with an overview of current work and promising avenues of inquiry into non-hedonic alternatives. (shrink)

Lengthy review of the 2020 Brill Companion to Hellenistic Astronomy with special reference to Neoplatonism.

Translation and commentary on the only surviving sustained work on Plato's Phaedrus from antiquity.

Bas van Fraassen’s Constructive Empiricism (CE) has been much discussed. There is, however, a curious feature of van Fraassen’s writings that has been overlooked up until now. This is that he sometimes capitalises certain key terms, notably “Induction”. This is done to differentiate a pragmatic small ‘i’ induction (which has epistemic import) from a rule-bound capital ‘I’ induction (which does not). In this paper, I argue that van Fraassen’s small letter/capital letter distinction reveals an underlying dualism, one that is reminiscent (...) of the notoriously problematic semantic dualism in Logical Positivism (between a theoretical language and an observation language). Despite partly developing CE to overcome Logical Positivism’s kind of dualism, van Fraassen seems to have tacitly endorsed it anyway. If so, then CE requires revision. It is, however, not clear how to conduct such a revision. It is not clear what the way forward should be once CE is understood as innately dualistic. (shrink)

Janette Dinishak’s work has helped shed critical light on the scientifically questionable and ethically troubling tendency in psychology and philosophy of mind to theorize autistic people as deficient empathizers. In a recently published reply on the Social Epistemology Review and Reply Collective, Dinishak (2024) brings her important perspective on this topic to bear on our paper “AAC Technology, Autism, and the Empathic Turn” (2022). Dinishak is largely sympathetic to our view while also raising a number of rich and thoughtful philosophical (...) questions. Since each of these questions is capable of jumpstarting a lengthy exchange, we focus our response on those questions that, we hope, are particularly fruitful for advancing further conversation. With this aim in mind, we also engage with some of Dinishak’s own insights from her 2016 chapter “Empathy, Like-mindedness, and Autism.” … [please read below the rest of the article]. (shrink)

In the present volume Proclus comments on the creation of the body of the universe in Plato's Timaeus.

A speaker's use of a declarative sentence in a context has two effects: it expresses a proposition and represents the speaker as knowing that proposition. This essay is about how to explain the second effect. The standard explanation is act-based. A speaker is represented as knowing because their use of the declarative in a context tokens the act-type of assertion and assertions represent knowledge in what's asserted. I propose a semantic explanation on which declaratives covertly host a "know"-parenthetical. A speaker (...) is thereby represented as knowing the proposition expressed because that is the semantic contribution of the parenthetical. I call this view parentheticalism and defend that it better explains knowledge representation than alternatives. As a consequence of outperforming assertoric explanations, parentheticalism opens the door to eliminating the act-type of assertion from linguistic theorizing. (shrink)

In his commentary on Aristotle's Metaphysics, Alexander of Aphrodisias quotes from Aristotle's now-lost work On the Ideas -- his account of the arguments offered by Plato for the theory of Forms and his criticisms of those arguments.

It considers how Plato argued for Forms or Ideas such as the Large Itself, the Just Itself and so on and whether Plato supposed that there were Forms corresponding to (...) sortal terms like Man.

It is an axiom of late neoplatonic metaphysics that all things are in all, but in each in an appropriate manner (ὀικείως, ET 103). These manners or modes of being are indicated by adverbial forms such as παραδειματικῶς or εἰκονικῶς. Thus, for example, the Forms are in the World Soul in the mode of images, while the objects in the sensible realm below Soul are in it in the manner of paradigms (in Tim. II 150.27). Among the many modes of (...) being distinguished by Proclus we find existence ὁλικῶς and μερικῶς – in the manner of a whole and in the manner of a part. This paper investigates the nature and significance of these mereological modes of being. (shrink)

The longevity of Aristotelian natural science consists not so much in the fact that Aristotle’s solutions to puzzles were accepted by generations of philosophers, but by the fact that the presuppositions that made these puzzles look puzzling were. In what follows I consider some Neoplatonic responses to two puzzles that Aristotle poses in De Caelo Book 2, Chapter 12. Both Proclus and Simplicius rejected Aristotle’s solutions to the puzzles he posed. In one case, but not in the other, they also (...) reassessed the relative importance of the presuppositions that created the puzzle. (shrink)

The commentary on Plato's Republic by Proclus (d. 485 CE), which takes the form of a series of essays, is the only sustained treatment of the dialogue to survive from antiquity. This three-volume edition presents the first complete English translation of Proclus' text, together with a general introduction that argues for the unity of Proclus' Commentary and orients the reader to the use which the Neoplatonists made of Plato's Republic in their educational program. Each volume is completed by a Greek (...) word index and an English-Greek glossary that will help non-specialists to track the occurrence of key terms throughout the translated text. The second volume of the edition presents Proclus' essays on the tripartite soul and the virtues, female philosopher rulers, and the metaphysics and epistemology of the central books of the Republic. The longest of the essays in Volume II interprets the nature and significance of the 'marriage number' whose miscalculation leads to the degeneration of the ideal city-state. (shrink)

Proclus' commentary on Plato's dialogue Timaeus is arguably the most important commentary on a text of Plato, offering unparalleled insights into eight centuries of Platonic interpretation. It has had an enormous influence on subsequent Plato scholarship. This edition offers the first new English translation of the work for nearly two centuries, building on significant recent advances in scholarship on Neoplatonic commentators. It provides an invaluable record of early interpretations of Plato's dialogue, while also presenting Proclus' own views on the meaning (...) and significance of Platonic philosophy. The present volume, the fifth in the edition, presents Proclus' commentary on the Timaeus, dealing with Proclus' account of static and flowing time; we see Proclus situating Plato's account of the motions of the stars and planets in relation to the astronomical theories of his day. The volume includes a substantial introduction, as well as notes that will shed new light on the text. (shrink)

The purpose of this paper is to reconstruct Frege’s argument against the relativity of truth contained in his posthumous writing Logic from 1897. Two points are made. The first is that the argument is a performative version of the common objection that truth relativism is incoherent: it is designed to show that the assertion of the relativity of truth involves a performative incoherence, because the absoluteness of truth is a success condition for making assertions. From a modern point of view, (...) the central premise of the argument, that the successful making of assertions depends on the absoluteness of truth, is highly doubtful. The second point is that this premise can be made plausible within the framework of Frege’s conception of truth and assertion: it can be derived from his thesis that, in order to put something forward as true, we do not need the word ‘true’, but only the assertoric force.

This essay argues that there are theoretical benefits to keeping distinct—more pervasively than the literature has done so far—the psychological states of imagining that p versus believing that in-the-story p, when it comes to cognition of fiction and other forms of narrative. Positing both in the minds of a story’s audience helps explain the full range of reactions characteristic of story consumption. This distinction also has interesting conceptual and explanatory dimensions that haven’t been carefully observed, and the two mental state (...) types make distinct contributions to generating emotional responses to stories. Finally, the differences between the mental states illuminate how a given story can be both shared with others and at the same time experienced as personal. (shrink)

Bestaande literatuur over Knoet de Grote zijn troonsbestijging, zoals dat van vooraanstaand 19e-eeuws historicus Edward Augustus Freeman, zou een ‘geromantiseerd’ beeld hebben geschetst van de kwestie.

The paper by Monteiro, Musten and Compson (2014) is to be commended for providing a comprehensive discussion of the compatibility issues arising from the integration of mindfulness – a 2,500-year-old Buddhist practice – into research and applied psychological domains. Consistent with the observations of various others (e.g., Dunne, 2011; Kang & Whittingham, 2010), Monteiro and colleagues have not only highlighted that there are differences in how Buddhism and contemporary mindfulness interventional approaches interpret and contextualize mindfulness, but there are also differing (...) interpretations of mindfulness within Buddhism. These apparent differences within Buddhism are arguably more noticeable when making comparisons across Buddhist vehicles (i.e., Theravada, Mahayana, Vajrayana), but to a lesser extent intra-vehicular differences can also be said to exist (i.e., differences between Buddhist traditions of the same vehicle). This commentary investigates the validity of some of these different Buddhist constructions of mindfulness, and then discusses how a better understanding of their scriptural and conceptual soundness (or lack thereof) may help to reconcile some of the actual and perceived incompatibility between Buddhist practice and contemporary secular mindfulness-based approaches.

I identify two versions of the scientific anti-realist’s selectionist explanation for the success of science: Bas van Fraassen’s original and K. Brad Wray’s newer interpretation. In Wray’s version, psycho-social factors internal to the scientific community – viz. scientists’ interests, goals, and preferences – explain the theory-selection practices that explain theory-success. I argue that, if Wray’s version were correct, then science should resemble art. In art, the artwork-selection practices that explain artwork-success appear faddish. They are prone to radical change over time. (...) Theory-selection practices that explain theory-success in science are however not faddish. They are mostly stable; that is, long-lived and consistent over time. This is because scientists (explicitly or implicitly) subscribe to what I will call the testability norm: scientific theories must make falsifiable claims about the external physical world. The testability norm and not psycho-sociology explains the theory-selection practices that explain theory-success in science. Contra Wray, scientific anti-realists can then maintain that the external physical world (as expressed in the testability norm) explains theory-success. (shrink)

This is a volume of twelve essays concerning the fundamental tension in personalised medicine between individual choice and the common good.

A philosophical analysis of the future of art must explicate art’s nature, as well as discuss the historical nature of art practice. Only so can one explain those contemporary developments in art which have led many people to doubt whether art even has a future. Arguably, art practice as we know it started with the installing of the modern system of the fine arts. I explain the pragmatics of art so understood, and suggest that we can define art, internally. We (...) need not resort to a nominalist approach that claims that something is a work of art if some representative of the art world says it is. Instead of such empty proceduralism, I explain how all art’s focal objects, persons and activities are mutually adjusted and can only be understood in light of the whole. Within that whole of art practice, the contemporary samples of art’s alleged failure can be assessed. Now the modern system treats the arts as aesthetic, and prescribes that to judge a work one has to experience it for oneself. Why this should be so, I explain in terms of the perceivability of the artist in the work. Next, art develops as a whole rather than in a piecemeal manner. Particular contemporary works may alienate the audience from art practice, yet once they are recognisably in a procedure which has clear artistic potency they can be incorporated fruitfully in the modern system as explained. In all, the future of art is the future of the modern system, unless the system as a whole goes. We see this happen with the Taliban, but do not ourselves seem to be vulnerable to such onslaught. Yet, our culture may be in the process of eliminating the human mind from the objective reality, and if nothing stops us, art too will come to an end. Luckily, by then we will not be such as to lament that demise. (shrink)

Ernst Mayr argued that the emergence of biology as a special science in the early nineteenth century was possible due to the demise of the mathematical model of science and its insistence on demonstrative knowledge. More recently, John Zammito has claimed that the rise of biology as a special science was due to a distinctive experimental, anti-metaphysical, anti-mathematical, and anti-rationalist strand of thought coming from outside of Germany. In this paper we argue that this narrative neglects the important role played (...) by the mathematical and axiomatic model of science in the emergence of biology as a special science. We show that several major actors involved in the emergence of biology as a science in Germany were working with an axiomatic conception of science that goes back at least to Aristotle and was popular in mid-eighteenth-century German academic circles due to its endorsement by Christian Wolff. More specifically, we show that at least two major contributors to the emergence of biology in Germany—Caspar Friedrich Wolff and Gottfried Reinhold Treviranus—sought to provide a conception of the new science of life that satisfies the criteria of a traditional axiomatic ideal of science. Both C.F. Wolff and Treviranus took over strong commitments to the axiomatic model of science from major philosophers of their time, Christian Wolff and Friedrich Wilhelm Joseph Schelling, respectively. The ideal of biology as an axiomatic science with specific biological fundamental concepts and principles thus played a role in the emergence of biology as a special science. (shrink)

Epistemic contextualism in the style of Lewis (1996) maintains that ascriptions of knowledge to a subject vary in truth with the alternatives that can be eliminated by the subject’s evidence in a context. Schaffer (2004, 2005, 2007, 2008, 2015), Schaffer and Knobe (2012), and Schaffer and Szabo ́ (2014) hold that the question under discussion or QUD always determines these alternatives in a context. This paper shows that the QUD does not perform such a role for "know" and uses this (...) result to draw a few lessons about the metasemantics of context- sensitivity. (shrink)

Assertion is widely regarded as an act associated with an epistemic position. To assert is to represent oneself as occupying this position and/or to be required to occupy this position. Within this approach, the most common view is that assertion is strong: the associated position is knowledge or certainty. But recent challenges to this common view present new data that are argued to be better explained by assertion being weak. Old data widely taken to support assertion being strong has also (...) been challenged. This paper examines such challenges and finds them wanting. Far from diminishing the case for strong assertion, carefully considering new and old data reveals that assertion is as strong as ever. (shrink)

This article explains how social norms can help to distinguish and understand a range of different kinds of social inequality and social hierarchy. My aim is to show how the literature on social norms can provide crucial resources to relational egalitarianism, which has made social equality and inequality into a central topic of contemporary normative political theorizing. The hope is that a more discriminating and detailed picture of different kinds of social inequality will help relational egalitarians move beyond a discussion (...) of the justice or injustice of social equality as a single general category.

Vehicle externalism maintains that the vehicles of our mental representations can be located outside of the head, that is, they need not be instantiated by neurons located inside the brain of the cogniser. But some disagree, insisting that ‘non-derived’, or ‘original’, content is the mark of the cognitive and that only biologically instantiated representational vehicles can have non-derived content, while the contents of all extra-neural representational vehicles are derived and thus lie outside the scope of the cognitive. In this paper (...) we develop one aspect of Menary’s vehicle externalist theory of cognitive integration—the process of enculturation—to respond to this longstanding objection. We offer examples of how expert mathematicians introduce new symbols to represent new mathematical possibilities that are not yet understood, and we argue that these new symbols have genuine non-derived content, that is, content that is not dependent on an act of interpretation by a cognitive agent and that does not derive from conventional associations, as many linguistic representations do.

Inspired by Bas van Fraassen’s Stance Empiricism, Anjan Chakravartty has developed a pluralistic account of what he calls epistemic stances towards scientific ontology. In this paper, I examine whether Chakravartty’s stance pluralism can exclude epistemic stances that licence pseudo-scientific practices like those found in Scientology. I argue that it cannot. Chakravartty’s stance pluralism is therefore prone to a form of debilitating relativism. I consequently argue that we need (1) some ground or constraint in relation to which epistemic stances can be (...) ranked by degrees, and (2) some way to demarcate science from pseudo-science so that we know what epistemic stances are about. Regarding (1), I argue that empirical detectability can serve as the ground in relation to which epistemic stances are ranked by degrees. Regarding (2), I argue for ranking sciences on a continuum according to established institutional criteria, rather than attempting to draw a strict demarcation. (shrink)
