Much of the debate about Aristotle’s criticisms of Plato has focused on the separability of the Forms. Here the dispute has to do with the ontological status of the Forms, in particular Plato’s claim for their ontological priority in relation to perceptible objects. Aristotle, however, also disputes the explanatory and causal roles that Plato claims for the Forms. This second criticism is independent of the first; even if the problem of the ontological status of the Forms were (...) resolved to Aristotle’s satisfaction, this second criticism would still stand. The problem here is not that there is no room for Aristotle’s four causes in Plato’s ontology; on the contrary, antecedents for all four can be found in Plato’s works. The problem, instead, is that Plato’s Forms fail to meet the general requirements that Aristotle sets out for the material, efficient, formal, and final causes of perceptible objects. Hence, even if the Forms were immanent in perceptible objects, they would still explain nothing about them. (shrink)

The ‘traditional’ interpretation of the Receptacle in Plato’s Timaeus maintains that its parts act as substrata to ordinary particulars such as dogs and tables: particulars are form-matter compounds to which Forms supply properties and the Receptacle supplies a substratum, as well as a space in which these compounds come to be. I argue, against this view, that parts of the Receptacle cannot act as substrata for those particulars. I also argue, making use of contemporary discussions of supersubstantivalism, against a (...) substratum interpretation that separates substratum and space in the Timaeus. (shrink)

The paper offers an interpretation of a disputed portion of Plato’s Theaetetus that is often called the Secret Doctrine. It is presented as a process ontology that takes two types of processes, swift and slow motions, as fundamental building blocks for ordinary material objects. Slow motions are powers which, when realized, generate swift motions, which, in turn, are subjectively bundled to compose sensible objects and perceivers. Although the reading of the Secret Doctrine offered here—a new version of the “Causal (...) Theory interpretation”—is not without problems, these problems are acknowledged in Plato’s text, confirming that this interpretation is correct. (shrink)

Gregory Vlastos has argued that Aristotle and other commentators on the Phaedo have mistakenly interpreted Plato’s Forms to be efficient causes. While Vlastos is correct that the Forms by themselves are not efficient causes, because of his neo-Kantianism he has misunderstood the close connection between the Forms and the explanation of change, including teleological change. This paper explores the connection in Plato’s Phaedo between the Forms, the nature of change, and efficient causality, and argues that Aristotle’s remarks are (...) not as misplaced as Vlastos claims.

Three problems threaten any account of philosophical rule in the Republic. First, Socrates is supposed to show that acting justly is always beneficial, but instead he extols the benefits of having a just soul. He leaves little reason to believe practical justice and psychic justice are connected and thus to believe that philosophers will act justly. In response to this problem, I show that just acts produce just souls. Since philosophers want to have just souls, they will act justly. Second, (...) Socrates’ alleged aim is to demonstrate that justice is beneficial, but philosophers, who have to give up a life of philosophy to rule, actually appear to be harmed by ruling. I explain that, since the founders of the city justly command them to rule, philosophers cannot, in fact, obtain a better life, and so ruling does not harm them. Third, it seems incongruous that philosophers, who should, as just people, jump at the opportunity to rule Kallipolis, must be compelled to rule. I show that Plato carefully constructs an educational system that produces rulers who do not want to rule, since such rulers alone will rule best. (shrink)

This essay begins with a consideration of one way in which animals and persons may be valued as “irreplaceable.” Drawing on both Plato and Pascal, I consider reasons for skepticism regarding the legitimacy of this sort of attachment. While I do not offer a complete defense against such skepticism, I do show that worries here may be overblown due to the conflation of distinct metaphysical and normative concerns. I then go on to clarify what sort of value is at (...) issue in cases of irreplaceable attachment. I characterize “unique value” as the kind of value attributed to a thing when we take that thing to be (theoretically, not just practically) irreplaceable. I then consider the relationship between this sort of value and intrinsic value. After considering the positions of Gowans, Moore, Korsgaard, Frankfurt, and others, I conclude that unique value is best understood not as a variety of intrinsic value but rather as one kind of final value that is grounded in the extrinsic properties of the object.

The Oxford Handbook of the Philosophy of Love offers a wide array of original essays on the nature and value of love. The editors, Christopher Grau and Aaron Smuts, have assembled an esteemed group of thinkers, including both established scholars and younger voices. The volume contains thirty-three essays addressing both issues about love as well as key philosophers who have contributed to the philosophy of love, such as Plato, Kierkegaard, Schopenhauer, and Murdoch. The topics range from central issues (...) about the nature and variety of love, the possibility of its rational justification, and whether it is an emotion, to the significance of love for law, economics, morality, and free will. The volume also contains an introduction to the subject as well as essays on love’s relation to jealousy, biotechnology, religion, knowledge, and several other topics. This wide-ranging handbook will be a key resource for specialists working on the philosophy of love, and a helpful guide for those looking to learn more about the area. (shrink)

A standard interpretation of Plato’s metaphysics holds that sensible particulars are images of Forms. Such particulars are fairly independent, like Aristotelian substances. I argue that this is incorrect: Platonic particulars are not Form images but aggregates of Form images, which are property-instances. Timaeus 49e-50a focuses on “this-suches” and even goes so far as to claim that they compose other things. I argue that Form images are this-suches, which are tropes. I also examine the geometrical account, showing that the geometrical (...) constituents of the elements are also Form images. Thus everything in the sensible world is composed of tropes. (shrink)

This paper provides a rational reconstruction of a Platonic trope bundle theory that is a live alternative to contemporary bundle theories. According to the theory, Platonic particulars are composed of what Plato calls images of Forms; contemporary metaphysicians call these tropes. Tropes are dependent on Forms and the Receptacle, while trope bundles are structured by natural kinds using the Phaedo's principles of inclusion and exclusion and the Timaeus’ geometrised elements, as well as by co-location in the Receptacle. Key elements (...) of discussion include persistence and abundance of Plato's tropes. The resulting theory is compared with contemporary trope bundle theories. (shrink)

The paper argues that Motion and Rest are “greatest kinds” and not just convenient examples, since they are all-pervading. Thus Motion and Rest can be jointly predicated of a single subject and can be predicated of each other, just as Sameness and Otherness can. While Sameness and Otherness are opposites, a single subject may be the same in one respect, namely, the same as itself, and other in another respect, namely, other than other things. Thus they can be predicated of (...) a single subject, and they can be predicated of each other, as well, since Sameness is other than other things and Otherness is the same as itself. The same explanation applies to Motion and Rest, as the paper demonstrates: a given subject may be in motion in one respect while being at rest in another respect. This distinction is made in the Sophist itself, right in the passage concerning the greatest kinds. Thus Motion and Rest should be considered greatest kinds on par with Being, Sameness, and Otherness, and each of these kinds pervades all other kinds. (shrink)

Plato’s Socrates holds that we always have reason to be just, since being just is essential for living a happy and successful life. In Book II of Plato’s Republic, Socrates’ main interlocutor, Glaucon, raises a vivid and powerful challenge to this claim. He presents the case of Gyges, a Lydian shepherd who possesses a ring that gives him the power of invisibility. Glaucon’s contention is that Gyges does not have reason to be just in this circumstance, since being (...) just will not promote his happiness. Thus, the argument poses the following challenge: what reason do we have to be just, particularly in circumstances where we can get away with injustice? In this essay, we describe Glaucon’s challenge, highlight its similarity to challenges offered by other skeptical figures in the history of philosophy, namely, Hobbes’ Foole and Hume’s sensible knave, and present three broad lines of response.

Mysticism and the sciences have traditionally been theoretical enemies, and the closer that philosophy allies itself with the sciences, the greater the philosophical tendency has been to attack mysticism as a possible avenue towards the acquisition of knowledge and/or understanding. Science and modern philosophy generally aim for epistemic disclosure of their contents, and, conversely, mysticism either aims at the restriction of esoteric knowledge, or claims such knowledge to be non-transferable. Thus the mystic is typically seen by analytic philosophers as a (...) variety of 'private language' speaker, although the plausibility of such a position is seemingly foreclosed by Wittgenstein's work in the Philosophical Investigations. Yorke re-examines Wittgenstein's conclusion on the matter of private language, and argues that so-called 'ineffable' mystical experiences, far from being a 'beetle in a box', can play a viable role in our public language-games, via renewed efforts at articulation.

We describe in our own words a visual phenomenon first described by Gallagher and Tsuchiya in 2020. The key to the phenomenon (as we describe it) is to direct one’s left eye at the image of one's left eye, while simultaneously directing one's right eye at the image of one's right eye. We suggest that one would naturally arrive at this phenomenon if one took a sufficiently literal reading of certain words of Socrates preserved in Plato's Alcibiades. We speculate (...) that perhaps Socrates was aware of the visual phenomenon in question. (shrink)

The review argues that Plato makes a valid distinction between inferior hypothetical and superior unhypothetical methods. Given the distinction, the book confuses the hypothetical for unhypothetical dialectic.

‘Greek Ethics’, an undergraduate class taught by the British moral philosopher N. J. H. Dent, introduced this reviewer to the ethical philosophy of ancient Greece. The class had a modest purview—a sequence of Socrates, Plato, and Aristotle—but it proved no less effective, in retrospect, than more synoptic classes for having taken this apparently limited and (for its students and academic level) appropriate focus. This excellent Companion will now serve any such class extremely well, allowing students a broader exposure than (...) that traditional sequence, without sacrificing the class’s circumscribed focus. The eighteen chapters encompass some of what went before, and surprisingly much of what came after, those three central philosophers—including, for instance, a discussion of Plotinus and his successors, as well as a discussion of Horace. The book will therefore be useful in many different types of class on ethical philosophy in the ancient world. This Companion will be useful not only to students, but also to at least three further groups: specialists in ancient Greek philosophy (since some contributors advance significant new positions, e.g. R. Kamtekar on Plato’s ethical psychology and D. Charles on Aristotle’s ‘ergon argument’ as already implicitly invoking ‘to kalon’); scholars working in academic subjects adjacent to ancient Greek philosophy; and contemporary moral philosophers.

In accordance with Leo Strauss’s ingenious suggestion, the Athenian Stranger of Plato’s Laws is best understood as an alternative ‘Socrates’, fleeing from the hemlock to Crete. Situated between Crito and Phaedo, Laws effectively tests the reader’s loyalty to the real Socrates who obeys Athenian law and dies cheerfully in Athens. Having separated Plato from the Stranger, a nuanced defence of Karl Popper’s suspicions about Laws confronts the apologetic readings of both Strauss and Christopher Bobonich. As hinted by (...) his preference for wine, the antidote for hemlock, the Athenian Stranger repeatedly proves himself the opposite of Socrates, particularly with respect to piety. Once the Stranger is recognized as ‘an unreliable narrator’, this apparently ponderous product of Plato’s senility becomes the taut thriller of an innovative teacher at the peak of his powers.

Commentators such as Terence Irwin (1999) and Christopher Shields (2006) claim that the Ring of Gyges argument in Republic II cannot demonstrate that justice is chosen only for its consequences. This is because valuing justice for its own sake is compatible with judging its value to be overridable. Through examination of the rational commitments involved in valuing normative ideals such as justice, we aim to show that this analysis is mistaken. If Glaucon is right that everyone would endorse Gyges’ (...) behavior, it follows that nobody values justice intrinsically. Hence, the Gyges story constitutes a more serious challenge than critics maintain. (shrink)

Value capture occurs when an agent’s values are rich and subtle; they enter a social environment that presents simplified — typically quantified — versions of those values; and those simplified articulations come to dominate their practical reasoning. Examples include becoming motivated by FitBit’s step counts, Twitter Likes and Re-tweets, citation rates, ranked lists of best schools, and Grade Point Averages. We are vulnerable to value capture because of the competitive advantage that such crisp and clear expressions of value have in (...) our private reasoning and our public justification. There is, however, a price. In value capture, we take a central component of our autonomy — our ongoing deliberation over the exact articulation of our values — and we outsource it. And the metrics to which we outsource usually engineered for the interests of some external force, like a large-scale institution’s interest in cross-contextual comprehensibility and quick aggregability. That outsourcing cuts off one of the key benefits to personal deliberation. In value capture, we no longer adjust our values and their articulations in light of own rich experience of the world. Our values should often be carefully tailored to our particular selves or our small-scale communities, but in value capture, we buy our values off the rack. In some cases – like decreasing CO2 emissions – the costs of non-tailored values are outweighed by the benefit of precise collective coordination. In other cases, like in our aesthetic lives, they are not. This suggests that we should want different values suited to different scales. We should want value federalism. Some values are perhaps best pursued at the largest-scale level, others at smaller scales. The problem occurs when we exhibit an excess preference for the largest-scale values – when we consistently let the universal metrics swamp our quieter interests. (shrink)

Much of the philosophical literature on causation has focused on the concept of actual causation, sometimes called token causation. In particular, it is this notion of actual causation that many philosophical theories of causation have attempted to capture.2 In this paper, we address the question: what purpose does this concept serve? As we shall see in the next section, one does not need this concept for purposes of prediction or rational deliberation. What then could the purpose be? We will argue (...) that one can gain an important clue here by looking at the ways in which causal judgments are shaped by people‘s understanding of norms. (shrink)

Representation theorems are often taken to provide the foundations for decision theory. First, they are taken to characterize degrees of belief and utilities. Second, they are taken to justify two fundamental rules of rationality: that we should have probabilistic degrees of belief and that we should act as expected utility maximizers. We argue that representation theorems cannot serve either of these foundational purposes, and that recent attempts to defend the foundational importance of representation theorems are unsuccessful. As a result, we (...) should reject these claims, and lay the foundations of decision theory on firmer ground. (shrink)

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived (...) of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage.

This paper examines three accounts of the sleeping beauty case: an account proposed by Adam Elga, an account proposed by David Lewis, and a third account defended in this paper. It provides two reasons for preferring the third account. First, this account does a good job of capturing the temporal continuity of our beliefs, while the accounts favored by Elga and Lewis do not. Second, Elga’s and Lewis’ treatments of the sleeping beauty case lead to highly counterintuitive consequences. The proposed (...) account also leads to counterintuitive consequences, but they’re not as bad as those of Elga’s account, and no worse than those of Lewis’ account. (shrink)

The question of the holistic structure of an organism is a recurring theme in the philosophy of biology and has been increasingly discussed again in recent years. Organisms have recently been described as complex systems that autonomously create, maintain and reproduce themselves while constantly interacting with their environment. Key focal points include their autopoiesis, autonomy, agency and teleological structure. This perspective marks a significant advancement from the 20th-century viewpoint, which predominantly saw organisms as genetically programmed, randomly generated and blindly selected (...) survival-machines. However, crucial questions about the shape and development of organisms still lack answers. Shape and development are deeply interconnected and seem to require a holistic approach. Here, I will briefly outline a phenomenological perspective which could provide a framework for seeking answers to these fundamental questions. In particular, I propose a common four-fold phenomenal structure of the developing organism and the cognising consciousness, which makes it possible to observe the agential and teleological structure of the organism "from within". This fourfold structure also describes the molecular level and thus provides a general organismic concept. It furthermore corresponds to the four Aristotelian "causes" (conditions). (shrink)

What is philosophy of science? Numerous manuals, anthologies or essays provide carefully reconstructed vantage points on the discipline that have been gained through expert and piecemeal historical analyses. In this paper, we address the question from a complementary perspective: we target the content of one major journal of the field—Philosophy of Science—and apply unsupervised text-mining methods to its complete corpus, from its start in 1934 until 2015. By running topic-modeling algorithms over the full-text corpus, we identified 126 key research topics (...) that span across 82 years. We also tracked their evolution and fluctuating significance over time in the journal articles. Our results concur with and document known and lesser-known episodes of the philosophy of science, including the rise and fall of logic and language-related topics, the relative stability of a metaphysical and ontological questioning (space and time, causation, natural kinds, realism), the significance of epistemological issues about the nature of scientific knowledge as well as the rise of a recent philosophy of biology and other trends. These analyses exemplify how computational text-mining methods can be used to provide an empirical large-scale and data-driven perspective on the history of philosophy of science that is complementary to other current historical approaches.

Ectogestation involves the gestation of a fetus in an ex utero environment. The possibility of this technology raises a significant question for the abortion debate: Does a woman’s right to end her pregnancy entail that she has a right to the death of the fetus when ectogestation is possible? Some have argued that it does not Mathison & Davis. Others claim that, while a woman alone does not possess an individual right to the death of the fetus, the genetic parents (...) have a collective right to its death Räsänen. In this paper, I argue that the possibility of ectogestation will radically transform the problem of abortion. The argument that I defend purports to show that, even if it is not a person, there is no right to the death of a fetus that could be safely removed from a human womb and gestated in an artificial womb, because there are competent people who are willing to care for and raise the fetus as it grows into a person. Thus, given the possibility of ectogestation, the moral status of the fetus plays no substantial role in determining whether there is a right to its death. (shrink)

In temporal binding, the temporal interval between one event and another, occurring some time later, is subjectively compressed. We discuss two ways in which temporal binding has been conceptualized. In studies showing temporal binding between a voluntary action and its causal consequences, such binding is typically interpreted as providing a measure of an implicit or pre-reflective “sense of agency”. However, temporal binding has also been observed in contexts not involving voluntary action, but only the passive observation of a cause-effect sequence. (...) In those contexts, it has been interpreted as a top-down effect on perception reflecting a belief in causality. These two views need not be in conflict with one another, if one thinks of them as concerning two separate mechanisms through which temporal binding can occur. In this paper, we explore an alternative possibility: that there is a unitary way of explaining temporal binding both within and outside the context of voluntary action as a top-down effect on perception reflecting a belief in causality. Any such explanation needs to account for ways in which agency, and factors connected with agency, have been shown to affect the strength of temporal binding. We show that principles of causal inference and causal selection already familiar from the literature on causal learning have the potential to explain why the strength of people’s causal beliefs can be affected by the extent to which they are themselves actively involved in bringing about events, thus in turn affecting binding.

In Modal Logic as Metaphysics, Timothy Williamson claims that the possibilism-actualism (P-A) distinction is badly muddled. In its place, he introduces a necessitism-contingentism (N-C) distinction that he claims is free of the confusions that purportedly plague the P-A distinction. In this paper I argue first that the P-A distinction, properly understood, is historically well-grounded and entirely coherent. I then look at the two arguments Williamson levels at the P-A distinction and find them wanting and show, moreover, that, when the N-C (...) distinction is broadened (as per Williamson himself) so as to enable necessitists to fend off contingentist objections, the P-A distinction can be faithfully reconstructed in terms of the N-C distinction. However, Williamson’s critique does point to a genuine shortcoming in the common formulation of the P-A distinction. I propose a new definition of the distinction in terms of essential properties that avoids this shortcoming. (shrink)

According to commonsense psychology, one is conscious of everything that one pays attention to, but one does not pay attention to all the things that one is conscious of. Recent lines of research purport to show that commonsense is mistaken on both of these points: Mack and Rock (1998) tell us that attention is necessary for consciousness, while Kentridge and Heywood (2001) claim that consciousness is not necessary for attention. If these lines of research were successful they would have important (...) implications regarding the prospects of using attention research to inform us about consciousness. The present essay shows that these lines of research are not successful, and that the commonsense picture of the relationship between attention and consciousness can be. (shrink)

Variants of the slogan that a succession of experiences does not amount to an experience of succession are commonplace in the philosophical literature on temporal experience. I distinguish three quite different arguments that might be captured using this slogan: the individuation argument, the unity argument, and the causal argument. Versions of the unity and the causal argument are often invoked in support of a particular view of the nature of temporal experience sometimes called intentionalism, and against a rival view sometimes (...) called extensionalism. I examine these arguments in light of the individuation argument. In particular, I show that the individuation argument is, at least prima facie, neutral between those two views of temporal experience; and once the individuation argument is in place, the unity and causal argument also lose their force against extensionalism.

Abstract: The article presents and critically discusses Walton's (and Reed's and Macagno's) argument scheme approach to a theory of good argumentation. In particular, four characteristics of Walton's approach are presented: 1. It presents normative requirements for argumentation in the form of argument schemes, i.e. relatively concrete type descriptions. 2. These schemata are enthymematic, i.e. they omit some of the premises required by other approaches. 3. The actual argument schemes are usually supplemented by critical questions. 4. The method is inductive, bottom-up, (...) gaining the normative schemata by abstraction from empirically collected groups of similar arguments. These characteristics, among others, are then discussed on the basis of four adequacy conditions: AC1: effectiveness in achieving the epistemic goal of obtaining and communicating justified acceptable opinions; AC2: completeness in capturing the good argument types; AC3: efficiency in achieving the goals; AC4: justification of the argument schemes. The discussion then reveals a number of weaknesses in Walton's argument schemes; among other things, they are neither effective (in the defined sense) nor truly justified. Contributing factors to these problems include the schema approach, i.e. not looking at the form of arguments, and the lack of epistemological foundations in the development of good types of arguments. However, the critical analyses reveal a better alternative: an epistemological approach based on epistemological principles. The article concludes with a detailed analysis of the scheme Practical Inference, which confirms the general criticism in detail. (shrink)

This paper examines two mistakes regarding David Lewis’ Principal Principle that have appeared in the recent literature. These particular mistakes are worth looking at for several reasons: The thoughts that lead to these mistakes are natural ones, the principles that result from these mistakes are untenable, and these mistakes have led to significant misconceptions regarding the role of admissibility and time. After correcting these mistakes, the paper discusses the correct roles of time and admissibility. With these results in hand, the (...) paper concludes by showing that one way of formulating the chance–credence relation has a distinct advantage over its rivals. (shrink)

In Reasons and Persons, Parfit (1984) posed a challenge: provide a satisfying normative account that solves the Non-Identity Problem, avoids the Repugnant and Absurd Conclusions, and solves the Mere-Addition Paradox. In response, some have suggested that we look toward person-affecting views of morality for a solution. But the person-affecting views that have been offered so far have been unable to satisfy Parfit's four requirements, and these views have been subject to a number of independent complaints. This paper describes a person-affecting (...) account which meets Parfit's challenge. The account satisfies Parfit's four requirements, and avoids many of the criticisms that have been raised against person-affecting views. (shrink)

This article presents theories of attention that attempt to derive their answer to the question of what attention is from their answers to the question of what it is for some activity to be done attentively. Such theories provide a distinctive account of the difficulties that are faced by the attempt to locate processes in the brain by which the phenomena of attention can be explained. Their account does not share the pessimism of theories suggesting that the concept of attention (...) is defective. Instead it reconstrues the explanatory relationship between attention and the processes that constitute it, in a way that is illustrated here by considering the relationship between attention and the processes that are identified by the biased competition theory. After considering some of the ways in which an adverbialist approach might be developed, the article concludes by suggesting some possible solutions to a problem concerning distraction, by which prominent adverbialist theories of attention have been dogged.

We discuss the social-epistemic aspects of Catherine Elgin’s theory of reflective equilibrium and understanding and argue that it yields an argument for the view that a crucial social-epistemic function of epistemic authorities is to foster understanding in their communities. We explore the competences that enable epistemic authorities to fulfil this role and argue that among them is an epistemic virtue we call “epistemic empathy”.

This paper examines the debate between permissive and impermissive forms of Bayesianism. It briefly discusses some considerations that might be offered by both sides of the debate, and then replies to some new arguments in favor of impermissivism offered by Roger White. First, it argues that White’s (Oxford studies in epistemology, vol 3. Oxford University Press, Oxford, pp 161–186, 2010) defense of Indifference Principles is unsuccessful. Second, it contends that White’s (Philos Perspect 19:445–459, 2005) arguments against permissive views do not (...) succeed. (shrink)

This paper argues that we should replace the common classification of theories of welfare into the categories of hedonism, desire theories, and objective list theories. The tripartite classification is objectionable because it is unduly narrow and it is confusing: it excludes theories of welfare that are worthy of discussion, and it obscures important distinctions. In its place, the paper proposes two independent classifications corresponding to a distinction emphasised by Roger Crisp: a four-category classification of enumerative theories (about which items constitute (...) welfare), and a four-category classification of explanatory theories (about why these items constitute welfare).

In the first chapter of his Knowledge and Lotteries, John Hawthorne argues that thinkers do not ordinarily know lottery propositions. His arguments depend on claims about the intimate connections between knowledge and assertion, epistemic possibility, practical reasoning, and theoretical reasoning. In this paper, we cast doubt on the proposed connections. We also put forward an alternative picture of belief and reasoning. In particular, we argue that assertion is governed by a Gricean constraint that makes no reference to knowledge, and that (...) practical reasoning has more to do with rational degrees of belief than with states of knowledge.

The aim of the paper is to develop general criteria of argumentative validity and adequacy for probabilistic arguments on the basis of the epistemological approach to argumentation. In this approach, as in most other approaches to argumentation, proabilistic arguments have been neglected somewhat. Nonetheless, criteria for several special types of probabilistic arguments have been developed, in particular by Richard Feldman and Christoph Lumer. In the first part (sects. 2-5) the epistemological basis of probabilistic arguments is discussed. With regard to the (...) philosophical interpretation of probabilities a new subjectivist, epistemic interpretation is proposed, which identifies probabilities with tendencies of evidence (sect. 2). After drawing the conclusions of this interpretation with respect to the syntactic features of the probability concept, e.g. one variable referring to the data base (sect. 3), the justification of basic probabilities (priors) by judgements of relative frequency (sect. 4) and the justification of derivative probabilities by means of the probability calculus are explained (sect. 5). The core of the paper is the definition of '(argumentatively) valid derivative probabilistic arguments', which provides exact conditions for epistemically good probabilistic arguments, together with conditions for the adequate use of such arguments for the aim of rationally convincing an addressee (sect. 6). Finally, some measures for improving the applicability of probabilistic reasoning are proposed (sect. 7). (shrink)

Standard decision theory has trouble handling cases involving acts without finite expected values. This paper has two aims. First, building on earlier work by Colyvan (2008), Easwaran (2014), and Lauwers and Vallentyne (2016), it develops a proposal for dealing with such cases, Difference Minimizing Theory. Difference Minimizing Theory provides satisfactory verdicts in a broader range of cases than its predecessors. And it vindicates two highly plausible principles of standard decision theory, Stochastic Equivalence and Stochastic Dominance. The second aim is to (...) assess some recent arguments against Stochastic Equivalence and Stochastic Dominance. If successful, these arguments refute Difference Minimizing Theory. This paper contends that these arguments are not successful. (shrink)

Das spezifische Ziel von Argumentationen ist nicht einfach, den Adressaten etwas glauben zu machen - dies wäre bloße Rhetorik ﷓, sondern: den Adressaten beim Erkennen der Akzeptabilität (insbesondere der Wahrheit) der These anzuleiten und ihn so zu begründetem Glauben, zu Erkenntnis zu führen. Argumentationen leiten das Erkennen an, indem sie in ihren Argumenten hinreichende Akzeptabilitätsbedingungen der These als erfüllt beurteilen und so den Adressaten implizit auffordern, diese Bedingungen zu überprüfen. Argumentationen sind gültig, wenn sie prinzipiell das Erkennen anleiten können; d. (...) h. wenn die genannten Akzeptabilitätsbedingungen hinreichend sind, wenn sie tatsächlich erfüllt (die Argumente also wahr) sind und wenn es irgendjemanden gibt, der zwar die Akzeptabilität der Argumente, nicht aber die der These erkannt hat. Eine gültige Argumentation ist adäquat, um einen bestimmten Adressaten rational zu überzeugen, wenn dieser u. a. die Akzeptabilität der Argumente, nicht aber die der These erkannt hat. Die in gültigen Argumentationen als erfüllt beurteilten Akzeptabilitätsbedingungen sind Konkretisierungen allgemeiner Erkenntnisprinzipien für die spezifische These, z. B. des deduktiven Erkenntnisprinzips: 'Eine Proposition ist wahr, wenn sie von wahren Propositionen logisch impliziert wird.' oder des erkenntnisgenetischen Erkenntnisprinzips: 'Eine Proposition ist wahr, wenn sie korrekt verifiziert worden ist.' Eine Konkretisierung des deduktiven Prinzips für eine These p wäre z. B.: 'p ist wahr, 1. wenn q und r wahr sind und 2. wenn q und r zusammen p logisch implizieren.' Sind beide Bedingungen erfüllt, so könnte 'q; r; also p.' eine gültige deduktive Argumentation sein. Die verschiedenen Argumentationstypen unterscheiden sich danach, auf welchem Erkenntnisprinzip sie basieren. Das argumentativ angeleitete Erkennen der Akzeptabilität der These funktioniert so: Der Adressat benutzt das von ihm (zumindest implizit) gewußte allgemeine Erkenntnisprinzip als Checkliste, auf der er nach dem Vorbringen der Argumente abhakt, welche Akzeptabilitätsbedingung des Erkenntnisprinzips durch das Zutreffen des Arguments jeweils erfüllt wird. Auf der Basis dieser Funktionsbestimmung werden in der "Praktischen Argumentationstheorie" (erstmalig) präzise Gültigkeitskriterien für Argumentationen allgemein und für mehrere spezielle Argumentationstypen entwickelt, erkenntnistheoretisch begründet und auf komplexe Argumentationsbeispiele aus Philosophie, Wissenschaft, Technik und Kultur angewendet. Die Analyse der erkenntnistheoretischen Grundlagen - der zugrundeliegenden Erkenntnisprinzipien - vor allem der interpretierenden und praktischen Argumentationen ist zudem von erheblicher Bedeutung weit über die Argumentationstheorie hinaus: für die Interpretationstheorie, die Handlungstheorie und die praktische Philosophie.

In “Bayesianism, Infinite Decisions, and Binding”, Arntzenius et al. (Mind 113:251–283, 2004 ) present cases in which agents who cannot bind themselves are driven by standard decision theory to choose sequences of actions with disastrous consequences. They defend standard decision theory by arguing that if a decision rule leads agents to disaster only when they cannot bind themselves, this should not be taken to be a mark against the decision rule. I show that this claim has surprising implications for a (...) number of other debates in decision theory. I then assess the plausibility of this claim, and suggest that it should be rejected.

We commonly explain the distinctive prudential and moral status of persons in terms of our mental capacities. I draw from recent work to argue that the common explanation is incomplete. I then develop a new explanation: We are ethically important because we are the object of a pattern of self-concern. I argue that the view solves moral problems posed by permissive ontologies, such as the recent personite problem.

The iterative conception of set is typically considered to provide the intuitive underpinnings for ZFCU (ZFC+Urelements). It is an easy theorem of ZFCU that all sets have a definite cardinality. But the iterative conception seems to be entirely consistent with the existence of “wide” sets, sets (of, in particular, urelements) that are larger than any cardinal. This paper diagnoses the source of the apparent disconnect here and proposes modifications of the Replacement and Powerset axioms so as to allow for the (...) existence of wide sets. Drawing upon Cantor’s notion of the absolute infinite, the paper argues that the modifications are warranted and preserve a robust iterative conception of set. The resulting theory is proved consistent relative to ZFC + “there exists an inaccessible cardinal number.”. (shrink)

The paper argues that an account of understanding should take the form of a Carnapian explication and acknowledge that understanding comes in degrees. An explication of objectual understanding is defended, which helps to make sense of the cognitive achievements and goals of science. The explication combines a necessary condition with three evaluative dimensions: An epistemic agent understands a subject matter by means of a theory only if the agent commits herself sufficiently to the theory of the subject matter, and to (...) the degree that the agent grasps the theory (i.e., is able to make use of it), the theory answers to the facts and the agent’s commitment to the theory is justified. The threshold for outright attributions of understanding is determined contextually. The explication has descriptive as well as normative facets and allows for the possibility of understanding by means of non-explanatory (e.g., purely classificatory) theories. (shrink)

The concept of “life” certainly is of some use to distinguish birds and beavers from water and stones. This pragmatic usefulness has led to its construal as a categorical predicate that can sift out living entities from non-living ones depending on their possessing specific properties—reproduction, metabolism, evolvability etc. In this paper, we argue against this binary construal of life. Using text-mining methods across over 30,000 scientific articles, we defend instead a degrees-of-life view and show how these methods can contribute to (...) experimental philosophy of science and concept explication. We apply topic-modeling algorithms to identify which specific properties are attributed to a target set of entities (bacteria, archaea, viruses, prions, plasmids, phages and the molecule of adenine). Eight major clusters of properties were identified together with their relative relevance for each target entity (two that relate to metabolism and catalysis, one to genetics, one to evolvability, one to structure, and—rather unexpectedly—three that concern interactions with the environment broadly construed). While aligning with intuitions—for instance about viruses being less alive than bacteria—these quantitative results also reveal differential degrees of performance that have so far remained elusive or overlooked. Taken together, these analyses provide a conceptual “lifeness space” that makes it possible to move away from a categorical construal of life by empirically assessing the relative lifeness of more-or-less alive entities.

Deference principles are principles that describe when, and to what extent, it’s rational to defer to others. Recently, some authors have used such principles to argue for Evidential Uniqueness, the claim that for every batch of evidence, there’s a unique doxastic state that it’s permissible for subjects with that total evidence to have. This paper has two aims. The first aim is to assess these deference-based arguments for Evidential Uniqueness. I’ll show that these arguments only work given a particular kind (...) of deference principle, and I’ll argue that there are reasons to reject these kinds of principles. The second aim of this paper is to spell out what a plausible generalized deference principle looks like. I’ll start by offering a principled rationale for taking deference to constrain rational belief. Then I’ll flesh out the kind of deference principle suggested by this rationale. Finally, I’ll show that this principle is both more plausible and more general than the principles used in the deference-based arguments for Evidential Uniqueness. (shrink)

In apparent motion experiments, participants are presented with what is in fact a succession of two brief stationary stimuli at two different locations, but they report an impression of movement. Philosophers have recently debated whether apparent motion provides evidence in favour of a particular account of the nature of temporal experience. I argue that the existing discussion in this area is premised on a mistaken view of the phenomenology of apparent motion and, as a result, the space of possible philosophical (...) positions has not yet been fully explored. In particular, I argue that the existence of apparent motion is compatible with an account of the nature of temporal experience that involves a version of direct realism. In doing so, I also argue against two other claims often made about apparent motion, viz. that apparent motion is the psychological phenomenon that underlies motion experience in the cinema, and that apparent motion is subjectively indistinguishable from real motion.

The coherence objection to the doctrine of the Incarnation maintains that it is impossible for one individual to have both the attributes of God and the attributes of a human being. This article examines Thomas Aquinas’s answer to this objection. I challenge the dominant, mereological interpretation of Aquinas’s position and, in light of this challenge, develop and defend a new alternative interpretation of Aquinas’s response to this important objection to Christian doctrine.

Conditionalization is a widely endorsed rule for updating one’s beliefs. But a sea of complaints have been raised about it, including worries regarding how the rule handles error correction, changing desiderata of theory choice, evidence loss, self-locating beliefs, learning about new theories, and confirmation. In light of such worries, a number of authors have suggested replacing Conditionalization with a different rule — one that appeals to what I’ll call “ur-priors”. But different authors have understood the rule in different ways, and (...) these different understandings solve different problems. In this paper, I aim to map out the terrain regarding these issues. I survey the different problems that might motivate the adoption of such a rule, flesh out the different understandings of the rule that have been proposed, and assess their pros and cons. I conclude by suggesting that one particular batch of proposals, proposals that appeal to what I’ll call “loaded evidential standards”, are especially promising. (shrink)
