Imagine a philosophy conference in Presocratic Greece. The hot question is: what are things made of? Followers of Thales say that everything is made of water, followers of Anaximenes that everything is made of air, and followers of Heraclitus that everything is made of fire. Nobody is quite clear what these claims mean, and some question whether the founders of the respective schools ever made them. But amongst the groupies there is a buzz about all the recent exciting progress. The mockers and doubters make plenty of noise too. They point out that no resolution of the dispute between the schools is in sight. They diagnose Thales, Anaximenes and Heraclitus as suffering from a tendency to overgeneralize. We can intelligibly ask what bread is made of, or what houses are made of, but to ask what things in general are made of is senseless, some suggest, because the question is posed without any conception of how to verify an answer; language has gone on holiday. Paleo-pragmatists invite everyone to relax, forget their futile pseudo-inquiries and do something useful instead.

The book records a series of philosophical exchanges between its authors, amounting to a debate extended over more than fifteen years. Its subject matter is the nature and scope of reason. A central case at issue is basic logical knowledge, and the justification for basic deductive inferences, but the arguments range far more widely, at stake the distinctions between analytic and synthetic, and between a priori and a posteriori. The discussion naturally involves problems about the conditions for linguistic understanding and competence, and what it might be to grasp a concept or to have an intuition. Since reason is central to philosophical method, there are associated implications for how philosophy itself works, or should work. In particular, the discussion raises fundamental concerns about how to approach epistemology.

This dissertation explores the concepts of naturalness, intrinsicality, and duplication. An intrinsic property is had by an object purely in virtue of the way that object is considered in itself. Duplicate objects are exactly similar, considered as they are in themselves. The perfectly natural properties are the most fundamental properties of the world, upon which the nature of the world depends. In this dissertation I develop a theory of intrinsicality, naturalness, and duplication and explore their philosophical applications. Chapter 1 introduces the notions, gives a preliminary survey of some proposed conceptual connections between the notions, and sketches some of their proposed applications. Chapter 2 gives my background assumptions and introduces notational conventions. In chapter 3 I present a theory of naturalness. Although I take ‘natural’ as a primitive, I clarify this notion by distinguishing and explicating various conceptions of naturalness. In chapter 4 I give a theory of various notions related to naturalness, especially intrinsicality and duplication. I show that ‘intrinsic’ and ‘duplicate’ are interde nable, and then give analyses of these and other notions in terms of naturalness. If, as I think likely, naturalness cannot be analyzed, then what is the proper response? David Lewis suggests: accept naturalness as a primitive. I am sympathetic to this proposal, but not to the form Lewis gives it: chapter 5 contains an argument against Lewis’s theory of naturalness. In chapter 6 I reject the idea that naturalness is analyzable in terms of immanent universals. I focus on the work of D. M. Armstrong. I also criticize Armstrong’s arguments against transcendent universals.

You drop the glass. It shatters. Here there are two distinct events, related by causation. What is this relation? ;I argue that the causal relation is best understood as the relation of being a probability-raiser of a process. I take the causal relata to be property instances at spatiotemporal regions, analyze the notion of a process in terms of sequences of events related by nomic subsumption , and understand probability-raising as counterfactual chance dependence in the style of David Lewis. Thus causes are understood as property instances on which the sequence of property instances constituting the lawful production of the effect depends. ;The understanding of causation offered here synthesizes the leading extant analyses of causation, which divide into probability-raising and process-linkage . I argue that the synthesis offered improves on its predecessors by developing a series of four problem cases: preemption, which shows causation without probability-raising, overlapping, which shows probability-raising without causation, double prevention, which shows causation without process-linkage, and mere traces, which shows process-linkage without causation. These objections interlock: the preempting cause and trace noncause are both process-linked to, but not probability-raising of, their alleged effects, while the double preventing cause and overlapping noncause are both probability-raising of, but not process-linked to, their alleged effects. Understanding causes as probability-raisers of processes resolves this problematic. A continuity requirement is then added which preserves these solutions, renders the relation continuous and transitive, and resolves a further problem case combining preemption and double-prevention involving causation without probability-raising or process-linkage

Quantum mechanics seems to portray nature as nonseparable, in the sense that it allows spatiotemporally separated entities to have states that cannot be fully specified without reference to each other. This is often said to implicate some form of “holism.” We aim to clarify what this means, and why this seems plausible. Our core idea is that the best explanation for nonseparability is a “common ground” explanation, which casts nonseparable entities in a holistic light, as scattered reflections of a more unified underlying reality.

'Christian theology', Vladimir Lossky observes, 'does not know of an abstract divinity'. By this one can read 'no doctrine of God abstracted from the rich sets of traditions that provide a context for the form of such a confession', traditions that shape reason doxologically to witness to the incomprehensible 'plentitude of being'. Sounding like Pascal he declares that 'the God of the philosophers and savants is introduced into the heart of the Living God, taking the place of the Deus absconditus, qui posuit tenebras labitulum suum'. Consequently, what Christian dogmatics speaks of as the 'Holy Spirit' cannot be conceived as the Spirit of such an abstracted God, but of the God who 'descends' in 'the divine person of Christ [who] makes human persons capable of an ascent in the Holy Spirit'

Non-Humean accounts of the metaphysics of nature posit either laws or powers in order to account for natural necessity and world-order. We argue that such monistic views face fundamental problems. On the one hand, neo-Aristotelians cannot give unproblematic power-based accounts of the functional laws among quantities offered by physical theories, as well as of the place of conservation laws and symmetries in a lawless ontology; in order to capture these characteristics, commitment to governing laws is indispensable. On the other hand, ontologies that entirely exclude some kind of power ascription to worldly entities face what we call the Governing Problem: such ontologies do not have the resources to give an adequate account of how laws play their governing role. We propose a novel dualist model, which, we argue, has the resources to solve the difficulties encountered by its two dominant competitors, without inheriting the problems of either view. According to the dualist model, both laws and powers are equally fundamental and irreducible to each other, and both are needed in order to give a satisfactory account of the nomological structure of the world. The dualist model constitutes thus a promising alternative to current monistic views in the metaphysics of science.

In this paper, I articulate and argue for a new truthmaker view of ontological commitment, which I call the “General Truthmaker View”: when one affirms a sentence, one is ontologically committed to there being something that makes true the proposition expressed by the sentence. This view comes apart from Quinean orthodoxy in that we are not ontologically committed to the things over which we quantify, and it comes apart from extant truthmaker views of ontological commitment in that we are not ontologically committed to the truthmakers of our sentences

This work explores the problem of the persistence of objects through change, given the assumption that objects are three-dimensional entities; and the continuation of events through time, given the assumption that events are four-dimensional entities. My main concern is to provide an informative metaphysical grounding of temporal continuation by identifying the primitive relations and properties into which this concept can be analyzed. My thesis is that entities a and b can be said to be the same three-dimensional object if a and b stand to each other in the relation of temporal continuation. a and b stand to each other in the relation of immediate temporal continuation, if they stand to each other in the relation of spatio-temporal continuity, they have the same essential parts, and they share a part in common. The parts of events also stand to each other in relations of temporal continuation, but they do not change across time and they need not stand to each other in the relation of spatio-temporal continuity. I propose a formal ontology of both objects and events, based on the primitive concepts of parthood and temporal continuation.

In this paper I will use sex by deception as a case study for highlighting some of the most tricky concepts around sexuality and moral psychology, including rape, consensual sex, sexual rights, sexual autonomy, sexual individuality, and disrespectful sex. I begin with a discussion of morally wrong sex as rooted in the breach of five sexual liberty rights that are derived from our fundamental human liberty rights: sexual self-possession, sexual autonomy, sexual individuality, sexual dignity and sexual privacy. I then argue (against the standard interpretation) that experimental findings in moral psychology show that the principle of respect for persons—a principle that grounds our human liberty rights—drives our intuitive moral judgments. In light of this discussion, I examine a puzzle about sex by deception—a puzzle which at first may seem to compel us to define 'rape' strictly in terms of force rather than sexual autonomy. I proceed by presenting an argument against the view that, as a rule, sex by deception undermines consent—a position held by prominent thinkers such as Philippe Patry (2001), Onora O’Neill (2003), Rubenfeld (2012), Tom Dougherty (2013a, 2013b), Joyce M. Short (2013), and Danielle Bromwich and Joseph Millum (2013, 2018). As we will see, sex following deception to increase your chances does not always constitute rape. Lying about your age, education, job, family background, marital status, or interest in a relationship, for example, does not make your sex partner incapable of consenting, which is to say that sex by deception need not be rape. I even go so far as to say that sex with another person that is facilitated by withholding information about having a venereal disease shouldn't be classified as rape. Although sex by deception doesn't compromise consent, it nonetheless violates the principle of respect for persons, not by vitiating sexual autonomy and compromising consent, but by failing to respect other sexual rights, such as our rights to sexual dignity, individuality, and privacy.

In the specific case of geography, the real world consists on the one hand of physical geographic features (bona fide objects) and on the other hand of various fiat objects, for example legal and administrative objects, including parcels of real estate, areas of given soil types, census tracts, and so on. It contains in addition the beliefs and actions of human beings directed towards these objects (for example, the actions of those who work in land registries or in census bureaux), and the relations between these beliefs and actions and their targets. The document is a Report of the Specialist Meeting held under the auspices of the Varenius Project.

In this book, Brit Brogaard defends the view that visual experience is like belief in having a representational content. Her defense differs from most previous defenses of this view in that it begins by looking at the language of ordinary speech. She provides a linguistic analysis of what we say when we say that things look a certain way or that the world appears to us to be a certain way. She then argues that this analysis can be used to argue for the view that visual experience has a representation content that mediates between you and the world when you visually perceive.

This volume provides novel approaches to a variety of questions about ambivalence and the role it plays in our lives. As the contributions illustrate, ambivalence finds its way into a gamut of philosophical and psychological debates about rationality, skepticism, emotions, intentionality, racism, global justice, well-being, mindfulness, and intersubjectivity. These debates concern questions like: “Is ambivalence distinct from uncertainty?”, “Does ambivalence affect the way we respond to paradoxes?”, “How can two nations come to an agreement about nuclear disarmament?”, “Is ambivalence irrational when it frustrates effective action?”, “Why do people who have had training in law enforcement commit such heinous acts of violence?”, “How does mindfulness resolve ambivalence?”, and “Why isn’t valuing your interests and ends and taking them seriously sufficient for self-love?”

There are three theories in the epistemology of modality that have received sustained attention over the past 20 years: conceivability-theory, counterfactual-theory, and deduction-theory. In this paper we argue that all three face what we call the problem of modal epistemic friction. One consequence of the problem is that for any of the three accounts to yield modal knowledge, the account must provide an epistemology of essence. We discuss an attempt to fend off the problem within the context of the internalism versus externalism debate about epistemic justification. We then investigate the effects that the PMEF has on reductive and non-reductive theories of the relation between essence and modality.

According to the foundationalist picture, shared by many rationalists and positivist empiricists, science makes cognitive progress by accumulating justified truths. Fallibilists, who point out that complete certainty cannot be achieved in empirical science, can still argue that even successions of false theories may progress toward the truth. This proposal was supported by Karl Popper with his notion of truthlikeness or verisimilitude. Popper’s own technical definition failed, but the idea that scientific progress means increasing truthlikeness can be expressed by defining degrees of truthlikeness in terms of similarities between states of affairs. This paper defends the verisimilitude approach against Alexander Bird who argues that the “semantic” definition is not sufficient to define progress, but the “epistemic” definition referring to justification and knowledge is more adequate. Here Bird ignores the crucial distinction between real progress and estimated progress, explicated by the difference between absolute degrees of truthlikeness and their evidence-relative expected values. Further, it is argued that Bird’s idea of returning to the cumulative model of growth requires an implausible trick of transforming past false theories into true ones.

The present paper aims to show that the reconstruction of the formal framework of the proofs in Pr. An. 1.15, as proposed by Malink and Rosen 2013 (‘Proof by Assumption of the Possible in Prior Analytics 1.15’, Mind, 122, 953-85) is due to affront a double impasse. Malink and Rosen argue convincingly that Aristotle operates with two different modal frameworks, one as found in the system of modal logic presented in Prior Analytics 1.3 and 8-22, and one occurring in many of Aristotle’s works, such as the Physics, De Caelo and the Metaphysics. However, they misconstrue the latter framework. More precisely, they misconstrue the domain of significance of what they call the ‘Principle of Necessitation’. As a consequence, bringing the two frameworks into one results into a contradictory modal logic. On the other hand, if the Principle of Necessitation is rectified, the proofs put forward by Malink and Rosen in the same paper are no longer available.

Most facts of grounding involve nonfundamental concepts, and thus must themselves be grounded. But how? The leading approaches—due to Bennett, deRosset, and Dagupta—are subject to objections. The way forward is to deny a presupposition common to the leading approaches, that there must be some simple formula governing how grounding facts are grounded. Everyone agrees that facts about cities might be grounded in some complex way about which we know little; we should say the same about the facts of grounding themselves. The kinds of facts that might enter into the grounds of the facts of grounding are explored at length.
