This paper explores the concept of "Nothingness" and its connection to Graham Priest's paraconsistent logic, with a critical focus on Heidegger's ontological perspective. Heidegger argues that logic and ontology are incompatible, and truth extends beyond mere propositions, tied to the indescribable experience of "Nothing." He contends that logical rules are not essential for ontological truth, leading to two conceptions of truth: fundamental and propositional. The study delves into this profound examination, considering the implications for understanding truth and the limitations of logic in grasping the elusive aspects of existence.

This book concerns the foundations of epistemic modality and hyperintensionality and their applications to the philosophy of mathematics. I examine the nature of epistemic modality, when the modal operator is interpreted as concerning both apriority and conceivability, as well as states of knowledge and belief. The book demonstrates how epistemic modality and hyperintensionality relate to the computational theory of mind; metaphysical modality and hyperintensionality; the types of mathematical modality and hyperintensionality; to the epistemic status of large cardinal axioms, undecidable propositions, and abstraction principles in the philosophy of mathematics; to the modal and hyperintensional profiles of the logic of rational intuition; and to the types of intention, when the latter is interpreted as a hyperintensional mental state. Chapter 2 argues for a novel type of expressivism based on the duality between the categories of coalgebras and algebras, and argues that the duality permits of the reconciliation between modal cognitivism and modal expressivism. I also develop a novel topic-sensitive truthmaker semantics for dynamic epistemic logic, and develop a novel dynamic two-dimensional semantics. Chapter 3 provides an abstraction principle for epistemic (hyper- )intensions. Chapter 4 advances a topic-sensitive two-dimensional truth-maker semantics, and provides three novel interpretations of the framework along with the epistemic and metasemantic. Chapter 5 applies the fixed points of the modal µ-calculus in order to account for the iteration of epistemic states in a single agent, by contrast to availing of modal axiom 4 (i.e.

I apply Dennett’s ‘real patterns’ idea to the ontology of physics, and specifically to the puzzle of how to relate the very different ontologies one finds at different scales in physics (e.g. particles vs continua, or fields vs particles). I argue that real patterns provide part but not all of the answer to the puzzle, and locate the rest of the answer in the structural-realist idea that ontology in general is secondary to (mathematically-presented) structure. I make some suggestions for the application of these ideas outside physics, including in the philosophy of mind context that motivated Dennett’s original proposal.

According to the causal-historical theory of reference, natural kind terms refer in virtue of complicated causal relations the speakers have to their environment. A common objection to the theory is that purely causal relations are insufficient to fix reference in a determinate fashion. The so-called hybrid view holds that what is also needed for successful fixing are true descriptions associated in the mind of the speaker with the referent. The main claim of this paper is that the objection fails: reference fixing of natural kind terms can be purely causal. The main argument draws inspiration from recent theoretical advances made in metaphysics of kinds by Marion Godman, Antonella Mallozzi, and David Papineau. The main claim is that their notion of super-explanatory properties may explain how reference of many kind terms can be fixed purely causally.

Among the various attempts to formulate a theory of quantum gravity, a class of approaches suggests that spacetime, as modeled by general relativity, is destined to fade away. A major issue becomes then to identify which structures may inhabit the more fundamental, non-spatiotemporal environment, as well as to explain the relationship with the higher-level spatiotemporal physics. Recently, it has been suggested that a certain understanding of functionalism is the proper tool to suitably account for the recovery of spacetime. Here the viability and usefulness of such a conceptual strategy is explored, by looking at the various levels of spacetime emergence a theory of quantum gravity is expected to deal with. Our conclusion will be that, while its viability is clear also in a quantum gravity context, the import of spacetime functionalism remains rather unsettled.

ABSTRACT: While there is considerable disagreement on the precise nature of material objecthood, it is standardly assumed that material objects must be spatial. In this paper, I provide two arguments against this assumption. The first argument is made from largely a priori considerations about modal plenitude. The possibility of non-spatial material objects follows from commitment to certain plausible principles governing material objecthood and plausible principles regarding modal plenitude. The second argument draws from current philosophical discussions regarding theories of quantum gravity and the emergence of spacetime. When it is appreciated what possible worlds these current theories commit us to, the possibility of non-spatial material objects will follow. Thus, either route will lead us to the possibility of non-spatial material objects. The significance of this result is that we need to revise our accounts of material objecthood to both accommodate these possibilities and the theories that lead to them.

Within the context of general relativity, Leibnizian metaphysics seems to demand that worlds are “maximal” with respect to a variety of space-time properties (Geroch 1970; Earman 1995). Here, we explore maximal worlds with respect to the “Heraclitus” asymmetry property which demands that of no pair of spacetime events have the same structure (Manchak and Barrett 2023). First, we show that Heraclitus-maximal worlds exist and that every Heraclitus world is contained in some Heraclitus-maximal world. This amounts to a type of compatibility between the Leibnizian and Heraclitian demands. Next, we consider the notion of “observationally indistinguishable” worlds (Glymour 1972, 1977; Malament 1977). We know that, modulo modest assumptions, any world is observationally indistinguishable from some other (non-isomorphic) world (Manchak 2009). But here we show a way out of this general epistemic predicament: if attention is restricted to Heraclitus-maximal worlds, then worlds are observationally indistinguishable if and only if they are isomorphic. Finally, we show a sense in which cosmic underdetermination can still arise for individual observers even if the Leibnizian and Heraclitian demands are met.

Philosophers and physicists often claim that the ‘privileged coordinates’ of a physical theory provide a window into its structure. The purpose of this paper is to examine whether this is the case. We show that there are general relativistic spacetimes that admit the same privileged coordinates but have different structure, and we infer from this that privileged coordinates do not provide a perfect guide to underlying structure. We conclude by isolating the conditions under which privileged coordinates do perfectly reflect structure.

Emotional hardcore and other music genres featuring screamed vocals are puzzling for the appreciator. The typical fan attaches appreciative value to musical screams of emotional pain all the while acknowledging it would be inappropriate to hold similar attitudes towards their sonically similar everyday counterpart: actual human screaming. Call this the screamed vocals problem. To solve the problem, I argue we must attend to the anti-sublimating aims that get expressed in the emotional hardcore vocalist’s choice to scream the lyrics. Screamed vocals help us see the value in rejecting (a) restrictive social norms of emotional expressiveness and (b) restrictive artistic norms about how one ought to express or represent pain in art, namely that if one is going to do so they must ensure the pain has been ‘beautified’. In developing this second point I argue that emotional hardcore is well-suited (though not individually so) for putting pressure on longstanding views in the history of aesthetics about the formal relationship between art and human pain.

The advanced division of cognitive labor generates a set of challenges and opportunities for professional philosophers. In this paper, I re-characterize the nature of synthetic philosophy in light of these challenges and opportunities. For my definition of synthetic philosophy see part 2. In part 1, I’ll remind you of the centrality of the division of labor to Plato’s Republic, and why this is especially salient in his banishment of the poets from his Kallipolis. I’ll then focus on the significance of an easily overlooked albeit rather significant character, Damon, mentioned in that dialogue. I’ll argue that if we take the relationship between Socrates and Damon seriously, we’ll notice that in modeling imperfect polities, Plato inscribes Socrates within the advanced division of cognitive labor who defers to Damon as an expert on a key feature of the art of government. In fact, I’ll argue that in Republic, Plato offers us at least two ways to conceptualize philosophy’s relationship to the sciences, and that he alerts us to the social significance of this.

Illusionists and a posteriori physicalists agree entirely on the metaphysical nature of reality—that all concrete entities are composed of fundamental physical entities. Despite this basic agreement on metaphysics, illusionists hold that phenomenal consciousness does not exist, whereas a posteriori physicalists hold that it does. One explanation of this disagreement would be that either the illusionists have too demanding a view about what consciousness requires, or the a posteriori physicalists have too tolerant a view. However, we will argue that this divergence of opinion is merely an upshot of the semantic indeterminacy of the term ‘conscious’ and its cognates. We shall back up this diagnosis by showing how semantic indeterminacy of the kind in question is a pervasive feature of language. By illustrating this pattern with a range of historical examples, we shall show how the dispute between the illusionists and their a posteriori physicalist opponents is one instance of a common kind of terminological imprecision. The disagreement between the illusionists and the a posteriori physicalists is thus not substantial. In effect, the two sides differ only about how to make an indeterminate term precise. The moral is that they should stop looking for arguments designed to settle the dispute in their favour.

It is one thing to believe something, and it is another to grasp it. For example, everyone knows that life is short, but most of us arguably do not fully grasp this fact. Grasping this fact can have a notable effect on our cognition and behavior, prompting us to reconsider how to best spend our limited time. Similarly, most of us know but seldom grasp that children are starving all around the world and that we could, if we put in a sufficient collective effort, halt much of this suffering. Grasping these facts makes us more inclined to donate to charity—or at least makes us more inclined to feel guilty if we don't. As both of these examples illustrate, grasping seems to be something above and beyond mere belief or knowledge, and it seems to make an important difference to our cognitive and decision-making processes.

A classic objection to Humeanism about scientific laws is that Humeans cannot make sense of the counterfactual invariance of the laws. For example, if there were ‘nothing in the entire history of the universe except a single electron’ (Lange, 2009, p. 55) then, intuitively, the laws would still be the same. But classic Humean views don’t seem to get such results.

The paper argues against a commitment to metaphysical necessity, semantic modalities are enough. The best approaches to elucidate the semantic modalities are (still) versions of lingustic ersatzism and fictionalism, even if only developed in parts. Within these necessary properties and the difference between natural and semantic laws can be accounted for. The proper background theory for this is an updated version of Logical Empiricism, which is congenial to recent trends in Structural Realism. The anti-metaphysical attitude of Logical Empiricism deserves revitalization. Another target besides metaphysical necessity are substantial forms of iterated modalities, as used, for instance, in the philosophy of religion.

Work in philosophy of mind often engages in descriptive phenomenology, i.e., in attempts to characterize the phenomenal character of our experience. Nagel’s famous discussion of what it’s like to be a bat demonstrates the difficulty of this enterprise (1974). But while Nagel located the difficulty in our absence of an objective vocabulary for describing experience, I argue that the problem runs deeper than that: we also lack an adequate subjective vocabulary for describing phenomenology. We struggle to describe our own phenomenal states in terms we ourselves find adequately expressive. This paper aims to flesh out why our phenomenological vocabulary is so impoverished – what I call the impoverishment problem. As I suggest, this problem has both practical and philosophical import. After fleshing out the problem in more detail, I draw some suggestive morals from the discussion in an effort to point the way forward towards a solution.

I distinguish five types of discrimination, three of which are personal-level and distinctively visual. I explain their implication relations. Then I argue that the plausibility of the claim that seeing something requires discriminating it, as opposed to simply attributing some properties to it, hinges on the type of discrimination under consideration. A weak form of discrimination trivializes the debate. Stronger notions of discrimination, however, cannot be understood without attribution. Attribution appears to form the fundamental level of personal-level representation.

In the Transcendental Aesthetic (TA), Kant is typically held to make negative assertations about “things in themselves,” namely that they are not spatial or temporal. These negative assertions stand behind the “neglected alternative” problem for Kant’s transcendental idealism. According to this problem, Kant may be entitled to assert that spatio-temporality is a subjective element of our cognition, but he cannot rule out that it may also be a feature of the objective world. In this paper, I show in a new way how Kant’s view (focusing on his conclusions about space) is not subject to this objection, by showing that he does not make the denial about mind-independent reality that he is typically held to make. The argument develops consequences of a new reading of Kant’s expression “an sich selbst” (‘in itself’; ‘in themselves’). I argue that “an sich selbst” or “per se” has a special, judgment-level role, so that this expression does not form new noun-terms adjectivally. It follows that the conceptual unit of Kant’s “Conclusions” in the TA is simply “things” (Dinge), since “things in themselves” is not a nominal expression; Kant adopts the Wolffian ontological use of “thing” as the basic kind-term for any existent. The arguments that things per se are not in space are arguments that space cannot be a necessary property or relations of things as a kind. I show that this does not involve the positive claim about mind-independent reality that inspires the neglected alternative objection.

In Plato’s Philebus, Socrates’ second account of ‘false’ pleasure (41d-42c) outlines a form of illusion: pleasures that appear greater than they are. I argue that these pleasures are perceptual misrepresentations. I then show that they are the grounds for a methodological critique of hedonism. Socrates identifies hedonism as a judgment about the value of pleasure based on a perceptual misrepresentation of size, witnessed paradigmatically in the ‘greatest pleasures’.

Time appears to us to pass. Some philosophers think that we should account for these experiences by appeal to change in what there unrestrictedly is (i.e. ontological change). I argue that such an appeal can only be the beginning of an account of passage. To show this, I consider a minimal type of view—a purely topological view— that attempts to account for experiences as of passage by an appeal to ontological change and topological features of the present. I argue that, if ontological change is needed to account for our experiences as of passage, then there are other features of our experiences as of passage that a purely topological view does not have the resources to explain. These features include the implacability of time’s passage, the orderliness of time’s passage, and the impossibility of a having a past that was never present.

I outline and defend a limited realism in socio-political conceptual amelioration (RSCA). RSCA claims that, in some cases, socio-political concepts are ameliorated to represent parts of a concept-independent reality more accurately. My main aim is to dissolve a seeming dilemma for RSCA: Whereas social kinds are mind-dependent (i.e. depending on human thought and action), realism implies that the kinds represented are ontologically independent of the concepts representing them. To dissolve this dilemma, I suggest considering two different roles concepts play concerning social kinds. Concepts can both generate social kinds and represent social kinds. Once a concept has generated a social kind, this social kind is part of a concept-independent reality that can be represented by different concepts. Thereby, RSCA allows ameliorated concepts to represent social kinds (e.g., rape, marriage) more accurately while acknowledging that human actions or concepts have generated these social kinds.

Der Beitrag wird zunächst unterschiedliche Altruismusbegriffe unterscheiden, insbesondere den biologischen und den psychologischen Altruismus. Ich werde Argumente für und gegen die Existenz des psychologischen Altruismus vorstellen und zeigen, dass insbesondere evolutionstheoretische Argumente, entgegen einer gängigen Auffassung, nicht gegen die Existenz eines genuinen psychologischen Altruismus sprechen. In einem zweiten Schritt werde ich auf empirische Studien zur psychologischen Motivation altruistischen Verhaltens und zur Entwicklung von pro-sozialen Einstellungen bei Kindern eingehen und diese kritisch diskutieren. Schließlich werde ich die These vertreten, dass der Altruismus primär insofern zur menschlichen Natur gehört, als Mensch zu sein wesentlich beinhaltet, sich und andere als Personen – im Sinne von sich gegenseitig Gründe gebend – zu begreifen.

I here defend microphysical manyism. According to microphysical manyism, each composite or higher-level object is a mere plurality of microphysical particles. After clarifying the commitments of the view, I offer two physicalist-friendly arguments in its favour. The first argument appeals to the Canberra Plan. Here I argue that microphysical particles acting in unison play the theoretical roles associated with composite objects - that they do everything that we think of composite objects as doing - and thus that composite objects are to be identified with pluralities of microphysical particles. Along the way I rebut the objections that pluralities of particles don’t display the right emergent, ‘lingering’, or modal properties to be good candidates for identification with higher-level objects. In the second argument I claim that microphysical manyism is uniquely able to capture a compelling and widespread physicalist intuition concerning the intimate nature of the relationship between higher-level, composite objects and the microphysical world.

Non-well-founded set theories allow set-theoretic exotica that standard ZFC will not allow, such as a set that has itself as its sole member. We can distinguish plenitudinous non-well-founded set theories, such as Boffa set theory, that allow infinitely many such sets, from restrictive theories, such as Finsler-Aczel or AFA, that allow exactly one. Plenitudinous non-well-founded set theories face a puzzle: nothing seems to explain the identity or distinctness of various of the sets they countenance. In this paper I aim to sharpen this puzzle, make clear who it does and does not apply to and, ultimately, to argue in favor of a plenitudinous theory like Boffa.

A drawback of the standard modal ontological proof is that it assumes that it is possible that there is something godlike. Kurt Gödel’s ontological proof seeks to establish this possibility with the help of certain axiological principles. But the axiological principles he relies on are not very plausible. And the same goes for other Gödelian ontological proofs in the literature. In this paper, I put forward a Gödelian ontological proof that only relies on plausible axiological principles. And I adopt the proof both for constant and variable domains. Nevertheless, the proof still needs the axiom that being godlike is positive in the sense of being a “purely good”-making property.

We know that Twitter is not what it used to be, but if you were around the Twittersphere in 2019, you may remember a series of long discussions, by very well-known neuroscientists, on the nature of neural representation. Reading from the bleachers, many philosophers like us couldn’t help but notice that some of the themes discussed in these threads were very familiar. Indeed, they were uncannily similar to the way philosophers of mind argued in the 1970s and 1980s about the prospects of naturalizing intentionality. While the recent debates were couched in terms of multivariate analyses, pattern similarity, and repetition suppression, they were ultimately about how to understand misrepresentation, representational content, and even reference to abstract and non-existent entities, albeit in the context of contemporary cognitive neuroscience. The time was then ripe to try to bring together both philosophers and neuroscientists interested in the nature of representation, so they could talk to and learn from each other.

A non-solipsist form of presentness is usually thought to require the non-relative copresentness of space-like separated events, where this requirement further implies the non-relative simultaneity of these events. Since special relativity is thought to rule out any global, non-relative simultaneity, typical non-solipsist forms of presentness are taken to be inconsistent with special relativity. To address this problem, we re-explain the relationship between the non-solipsism of presentness and co-presentness by appealing to metaphysical indeterminacy. We propose presentness indeterminacy, the thesis that where an event, p, is determinately present, any event in space-like relation to p lacks a determinate tense. We argue that for many theories of time, indeterminate co-presentness is all that the non-solipsism of presentness requires. Since there is no determinate co-presentness, the inconsistency between presentness and special relativity in these theories disappears.

The dispute about whether there is indeterminacy in the world is long and inconclusive. At first glance, it seems like quantum mechanics ought to provide a quick, empirical resolution to the debate: prima facie, a photon in a superposition of right-polarized and left-polarized states has an indeterminate polarization. But quantum mechanics has not provided any such resolution; the controversy drags on. In this paper, I suggest some reasons for this impasse, and lay out a path forward.
