    Atomic sentences – or the propositions they express – can be true, as can logically complex sentences composed out of atomic sentences. A comprehensive metaphysics of truth aims to tell us, in an informative way, what the truth of any sentence whatsoever consists in, be it atomic or complex. Monists about truth are committed to truth always consisting in the same thing, no matter which sentence you consider. Pluralists about truth think that the nature of truth is different for different sets of sentences. The received view seems to be that logically complex sentences – and indeed logic itself – somehow impose a monistic constraint on any comprehensive metaphysics of truth. In what follows, I argue that the received view is mistaken.

    Hardin’s (1988) empirically-grounded argument for color eliminativism has defined the color realism debate for the last thirty years. By Hardin’s own estimation, phenomenal structure – the unique/binary hue distinction in particular – poses the greatest problem for color realism. Examination of relevant empirical findings shows that claims about the unique hues which play a central role in the argument from phenomenal structure should be rejected. Chiefly, contrary to widespread belief amongst philosophers and scientists, the unique hues do not play a fundamental role in determining all color appearances. Among the consequences of this result is that greater attention should be paid to certain proposals for putting the structure of phenomenal color into principled correspondence with surface reflectance properties. While color realism is not fully vindicated, it has much greater empirical plausibility than previously thought.

    I propose a division of the literature on natural kinds into metaphysical worries, semantic worries, and methodological worries. I argue that the latter set of worries, which concern how classification influences scientific practices, should occupy centre stage in philosophy of science discussions about natural kinds. I apply this methodological framework to the problems of classifying chemical species and nanomaterials. I show that classification in nanoscience differs from classification in chemistry because the latter relies heavily on compositional identity, whereas the former must consider additional properties, namely, size, shape, and surface chemistry. I use this difference to argue for a scale-dependent theory of scientific classification.

    The idea that the world is structured—that some things are “built” out of others—has been at the forefront of recent metaphysics. Making Things Up presents a comprehensive and distinctive view on these matters. It is a model of good philosophy: ambitious, insightful, open-minded, and guided by sound judgment. Don’t be deceived by its conversational tone. The book contains riches on the surface and below; new layers are revealed with each reading.

    Ontological arguments like those of Gödel (1995) and Pruss (2009; 2012) rely on premises that initially seem plausible, but on closer scrutiny are not. The premises have modal import that is required for the arguments but is not immediately grasped on inspection, and which ultimately undermines the simpler logical intuitions that make the premises seem plausible. Furthermore, the notion of necessity that they involve goes unspecified, and yet must go beyond standard varieties of logical necessity. This leaves us little reason to believe the premises, while their implausible existential import gives us good reason not to.

    It is a striking fact from reverse mathematics that almost all theorems of countable and countably representable mathematics are equivalent to just five subsystems of second order arithmetic. The standard view is that the significance of these equivalences lies in the set existence principles that are necessary and sufficient to prove those theorems. In this article I analyse the role of set existence principles in reverse mathematics, and argue that they are best understood as closure conditions on the powerset of the natural numbers.

    This article follows on the introductory article “Direct Logic for Intelligent Applications” [Hewitt 2017a]. Strong Types enable new mathematical theorems to be proved including the Formal Consistency of Mathematics. Also, Strong Types are extremely important in Direct Logic because they block all known paradoxes[Cantini and Bruni 2017]. Blocking known paradoxes makes Direct Logic safer for use in Intelligent Applications by preventing security holes.

    Adverbialist theories of thought such as those advanced by Hare (1969) and Sellars (1969) promise an ontologically sleek understanding of a variety of intentional states, but such theories have been largely abandoned due to the ‘many-property problem’. In an attempt to revitalize this otherwise attractive theory, in a series of papers as well as his recent book, Uriah Kriegel has offered a novel reply to the ‘many-property problem’ and on its basis he argues that ‘adverbialism about intentionality is alive and well’. If true, Kriegel will have shown that the logical landscape has long been unnecessarily constrained. His key idea is that the many-property problem can be overcome by appreciating that mental states stand in the determinable-determinate relation to one another. The present paper shows that this relation can’t save adverbialism because it would require thinkers to think more thoughts than they need be thinking.

    Giacomo (Jacopo) Zabarella (b. 1533 in Padua, d. 1589 in Padua) is considered the prime representative of Renaissance Italian Aristotelianism. Known most of all for his writings on logic and methodology, Zabarella was an alumnus of the University of Padua, where he received his Ph.D. in philosophy. Throughout his teaching career at his native university, he also taught philosophy of nature and science of the soul (De anima). Among his main works are the collected logical works Opera logica (1578) and writings on natural philosophy, De rebus naturalibus (1590). Zabarella was an orthodox Aristotelian seeking to defend the scientific status of theoretical natural philosophy against the pressures emanating from the practical disciplines, i.e., the art of medicine and anatomy.

    I will begin by reviewing three classic points in philosophy of mind. Point 1 is that there is a theory, which I will call here ‘the reflexive theory’ or ‘RT’ for short, according to which a (psychological) state is a conscious state of a subject only if the subject of the state is conscious of being in the state. Since ‘is conscious of’ is a rough synonym of ‘is aware of’, we may also say that, according to RT, a psychological state is a conscious state of a subject only if the subject of the state is aware of being in the state. Point 2 is that RT faces a regress objection; that is, it is apparently committed to an infinite regress of a problematic sort. The objection might be formulated this way. First Premise: if RT is true, then, if you instantiate one conscious state you instantiate an infinity of conscious states. Second Premise: you do not instantiate an infinity of conscious states. Conclusion: either RT is false or you never instantiate a conscious state—a disaster for a theory of consciousness!

    Humean accounts of natural lawhood (such as Lewis’s) have often been criticized as unable to account for the laws’ characteristic explanatory power in science. Loewer (Philos Stud 160:115–137, 2012) has replied that these criticisms fail to distinguish grounding explanations from scientific explanations. Lange (Philos Stud 164:255–261, 2013) has replied by arguing that grounding explanations and scientific explanations are linked by a transitivity principle, which can be used to argue that Humean accounts of natural law violate the prohibition on self-explanation. Lange’s argument has been sharply criticized by Hicks and van Elswyk (Philos Stud 172:433– 443, 2015), Marshall (Philos Stud 172:3145–3165, 2015), and Miller (Philos Stud 172:1311–1332, 2015). This paper shows how Lange’s argument can withstand these criticisms once the transitivity principle and the prohibition on self-explanation are properly refined. The transitivity principle should be refined to accommodate contrasts in the explanans and explanandum. The prohibition on self-explanation should be refined so that it precludes a given fact p from helping to explain why some other fact q helps to explain why p. In this way, the transitivity principle avoids having counterintuitive consequences in cases involving macrostates having multiple possible microrealizations. The transitivity principle is perfectly compatible with the irreducibility of macroexplanations to microexplanations and with the diversity of the relations that can underwrite scientific explanations.

    The meta-problem of consciousness is (to a first approximation) the problem of explaining why we think that there is a problem of consciousness. Just as metacognition is cognition about cognition, and a metatheory is a theory about theories, the metaproblem is a problem about a problem. The initial problem is the hard problem of consciousness: why and how do physical processes in the brain give rise to conscious experience? The relevant sort of consciousness here is phenomenal consciousness. A system is phenomenally conscious if there is something it is like to be that system, from the first-person point of view. The meta-problem is roughly the problem of explaining why we think phenomenal consciousness poses a hard problem, or in other terms, the problem of explaining why we think consciousness is hard to explain.

    I argue for patternism, a new answer to the question of when some objects compose a whole. None of the standard principles of composition comfortably capture our natural judgments, such as that my cat exists and my table exists, but there is nothing wholly composed of them. Patternism holds, very roughly, that some things compose a whole whenever together they form a “real pattern”. Plausibly we are inclined to acknowledge the existence of my cat and my table but not of their fusion, because the first two have a kind of internal organizational coherence that their putative fusion lacks. Kolmogorov complexity theory supplies the needed rigorous sense of “internal organizational coherence”.

During his period at the University of Jena (1787–94), Reinhold proclaimed the need for a more “scientific” and systematic presentation of the Critical philosophy, one based upon a single, self-evident first principle. In an effort to satisfy this need, he expounded his own “Elementary Philosophy” in a series of influential works between 1789 and 1791.

    In my book Understanding Scientific Progress (Maxwell 2017), I argue that fundamental philosophical problems about scientific progress, above all the problem of induction, cannot be solved granted standard empiricism (SE), a doctrine which most scientists and philosophers of science take for granted. A key tenet of SE is that no permanent thesis about the world can be accepted as a part of scientific knowledge independent of evidence. For a number of reasons, we need to adopt a rather different conception of science which I call aim-oriented empiricism (AOE). This holds that we need to construe physics as accepting, as a part of theoretical scientific knowledge, a hierarchy of metaphysical theses about the comprehensibility and knowability of the universe, these theses becoming increasingly insubstantial as we go up the hierarchy. Fundamental philosophical problems about scientific progress, including the problems of induction, theory unity, verisimilitude and scientific discovery, which cannot be solved granted SE, can be solved granted AOE.

    [Editor's Note: The following new entry by Ana María Mora-Márquez replaces the former entry on this topic by the previous author.] Simon of Faversham († 1306) was a thirteenth-century scholar, mainly known as a commentator on Aristotle’s logic and natural philosophy. He is considered a modist, among other things because of his use of the notions of modi praedicandi and modi essendi in his commentary on Aristotle’s Categories (cf. Marmo 1999). Simon’s work as an Aristotelian commentator heavily relies on Albert the Great’s paraphrases on the Aristotelian corpus. Simon’s question-commentaries often portray key medieval discussions in a somewhat undeveloped state.

    The central question of my paper is whether there is a coherent logical theory in which truth is construed in epistemic terms and in which also some version of the law of excluded middle is defended. Brentano in his later writings has such a theory. My first question is whether his theory is consistent. I also make a comparison between Brentano’s view and that of an intuitionist at the present day, namely Per Martin-Löf. Such a comparison might provide some insight into what is essential to a theory that understands truth in epistemic terms.

    Dom Robert Desgabets (1610–1678) was an early defender and teacher of the Cartesian philosophy at St. Maur in the region of Lorraine, France. He was born in Ancemont and in 1636 became a monk in the Benedictine order. He taught theology at Saint-Evre at Toul between 1635–1655, and served as Procurer General of Mihiel to Paris during 1648–49. Although he is little-known today, he played an important role in the development and transmission of the Cartesian philosophy, especially in Paris and Toulouse. He is best known for his role in the theological controversy over the Cartesian explication of the Eucharist (Desgabets, 1671), and for his defense of Nicolas Malebranche against the skeptic Simon Foucher (Desgabets, 1675).

    The following general attitude to mathematics seems plausible: standard claims, such as ‘there are infinitely many primes’ or ‘every consistent set of sentences has a model’, are true; nevertheless, if one rifles through the fundamental furniture of the universe, one will not find mathematical objects, such as numbers, sets or models. A natural way of making sense of this attitude is to augment it with the following thought: this is possible because such standard claims have paraphrases that make clear that their truth does not require the fundamental existence of such objects. This paper will draw out some surprising consequences of this general approach to mathematics—an approach that I call paraphrase anti-realism. These consequences concern the relationship between logical structure, on the one hand, and explanatory structure, on the other.

    My article aims to revisit the aesthetic thought of the Austrian psychologist and philosopher Joseph Wilhelm Nahlowsky (1812–1885), as expounded in his formerly famous monograph Das Gefühlsleben. I show that although Nahlowsky was a direct heir of Herbart, his ideas were in keeping with both the contemporary debate about form and content and the then-emerging paradigm of psychological aesthetics. I describe his developments on aesthetic feelings and his remarkable attempt to elaborate a general psycho-affective theory on the experience of the aesthetic object. I also discuss the importance of the notion of form, inherited from Herbart, in his psychological aesthetics. Finally, I demonstrate that, in addition to having marked an ‘affective’ turn in Herbartianism, Nahlowsky was a key actor in the evolution of ideas in psychological aesthetics in the second half of the nineteenth century.

    The world is awake. That can stand as a slogan for panpsychism: the view that I will understand here as holding that consciousness is fundamental and ubiquitous in nature. This does not mean that everything is conscious. Whether a particular non-fundamental entity is conscious will depend upon the arrangement of its fundamental constituents given some presumed laws of ‘mental chemistry’ which govern the emergence of complex forms of consciousness. So in bare outline panpsychism presents a familiar picture of fundamental features interacting in ways to generate more complex forms. Nor does panpsychism entail that sophisticated, high level consciousness is ubiquitous. The term ‘consciousness’ is notoriously hard to define and the victim of multitudes of more or less well motivated (re)definitions. I aim for a minimal conception. For contrast, compare this expansive notion of consciousness, plucked merely for illustrative purposes from Aaronson (2016): ‘displaying intelligent behavior (by passing the Turing Test or some other means) might be thought a necessary condition for consciousness’. On the minimal conception, consciousness does not at all require that ability to pass the Turing test. Feeling pain (or any other sensation) alone is sufficient for consciousness. It’s worth noting this because there is a somewhat pernicious ambiguity lurking here, that between a property and the evidence we have for ascribing it. Although still inaccurate, Aaronson’s dictum is closer to the truth if we change the final phrase to ‘a necessary condition for the ascription of consciousness’. But note that we can have theoretical reasons for ascribing a property without there being any direct observational evidence for the ascription. So, the kind of minimal consciousness in question is not ‘self-consciousness’ or ‘transcendental subjectivity’, or awareness of the self as a subject, or awareness of one’s own mental states, or the ability to conceptualize one’s own mental states as such. Consciousness is simply sentience, or the way things are present (to the mind).

    Øystein Linnebo and Richard Pettigrew ([2014]) have recently developed a version of noneliminative mathematical structuralism based on Fregean abstraction principles. They argue that their theory of abstract structures proves a consistent version of the structuralist thesis that positions in abstract structures only have structural properties. They do this by defining a subset of the properties of positions in structures, so-called fundamental properties, and argue that all fundamental properties of positions are structural. In this paper, we argue that the structuralist thesis, even when restricted to fundamental properties, does not follow from the theory of structures that Linnebo and Pettigrew have developed. To make their account work, we propose a formal framework in terms of Kripke models that makes structural abstraction precise. The formal framework allows us to articulate a revised definition of fundamental properties, understood as intensional properties. Based on this revised definition, we show that the restricted version of the structuralist thesis holds.

    Fictions evoke imagery, and their value consists partly in that achievement. This paper offers analysis of this neglected topic. Section I identifies relevant philosophical background. II offers a working definition of imagery. III identifies empirical work on visual imagery. IV and V criticize imagery essentialism, through the lens of genuine fictional narratives. This outcome, though, is not wholly critical. The expressed spirit of imagery essentialism is to encourage philosophers to "put the image back into the imagination." The weakened conclusion is that while an image is not essential to imagining, it should be returned to our theories of imagination.

This is used to provide conceptual justification for a method that is applied to obtain the Schr ödinger equation, the Klein-Gordon equation, and the Klein-Gordon equation for a particle in an electromagnetic field. Additionally, it is argued that the existence of such state is incompatible with indirect realism; and the discussion suggests that a panexeperientialist view is a straightforward means to embrace it.

    Presentism is the view that only present things exist (Hinchliff 1996: 123; Crisp 2004: 15; Markosian 2004: 47–48). So understood, presentism is an ontological doctrine; it’s a view about what exists (what there is), absolutely and unrestrictedly. The view is the subject of extensive discussion in the literature, with much of it focused on the problems that presentism allegedly faces. Thus, much of the literature that frames the development of presentism has grown up either in formulating objections to the view (e.g., Sider 2001: 11–52), or in response to such objections (e.g., Bigelow 1996; Markosian 2004), with exceptions to this largely coming via the ways in which presentism is motivated.

    I present an argument against a relational theory of spacetime that regards spacetime as a ‘structural quality of the field’. The argument takes the form of a trilemma. To make the argument, I focus on relativistic worlds in which there exist just two fields, an electromagnetic field and a gravitational field. Then there are three options: either spacetime is a structural quality of each field separately, both fields together, or one field but not the other. I argue that the first option founders on a problem of geometric coordination and that the second and third options collapse into substantivalism. In particular, on the third option it becomes clear that the relationalist’s path to Leibniz equivalence is no simpler or more straightforward than the substantivalist’s.
