The present author developed a calculus for the logic of ‘because’. In a recent paper in this journal, it has been claimed that the central inference rules for the logic are invalid and that the intuition upon which the rules are based is not accounted for. This note criticises these arguments and presents an independent argument in favour of the rules used in the logic.

Bernard Bolzano développe une théorie exhaustive et très élaborée des propositions comme entités structurées et composées de concepts. L’une de ses thèses principales consiste à dire que toutes les propositions ont en commun la même structure : « A – a – b ». Cet article examine le rôle que jouent les propriétés eu égard à cette thèse. Lorsque les propriétés figurent dans les théories sémantiques standards, elles sont généralement conçues comme des entités partageables, en d’autres mots, comme des universaux. (...) Je montre que Bolzano croyait que ce sont bien plutôt des propriétés particularisées qui tombent sous la représentation-prédicat d’une proposition. De là émerge une sémantique plutôt inhabituelle : une proposition de la forme [A – a – b] est vraie ssi une des propriétés particularisées qui se tiennent sous la représentation-prédicat [b] inhère au sujet de la proposition, c’est-à-dire l’entité dénotée par la représentation-sujet [A].Bernard Bolzano developed a highly elaborate and comprising account of propositions as structured entities composed of concepts. One of his main contentions was that all propositions share a common structure : “A – has – b”. The main part of my paper is a discussion of the role which properties play for this thesis and thus in Bolzano’s semantics. Where properties feature as semantic values in standard semantic theories they are conceived of as shareable entities, in other words, as universals. I show that it is particularised properties which Bolzano thought to be the entities standing under the predicate-ideas of propositions. With this idea, a rather uncommon semantic arises : a proposition of the form [A – has – b] will be true iff one of the particularised properties standing under the predicate-idea [b] inheres in the subject of the proposition, i.e. in the entity denoted by the subject-idea [A].

Anthony Everett has argued that fictional realism entails that some fictional characters are indeterminately identical. Benjamin Schnieder and Tatjana von Solodkoff deny that fictional realism has that entailment. But, we argue in this paper, their view is arbitrary, since there is no reason to prefer their principles to alternative ones. We don’t take this to show that fictional realism should be rejected. But we do take this to show that fictional realists who deny that some fictional characters are indeterminately (...) identical need another response to Everett’s argument. (shrink)

Bridging the gap between the world of science and the realm of the spiritual, B. Alan Wallace introduces a natural theory of human consciousness that has its roots in contemporary physics and Buddhism. Wallace's "special theory of ontological relativity" suggests that mental phenomena are _conditioned_ by the brain, but do not _emerge_ from it. Rather, the entire natural world of mind and matter, subjects and objects, arises from a unitary dimension of reality that is more fundamental than these dualities, as (...) proposed by Wolfgang Pauli and Carl Jung. To test his hypothesis, Wallace employs the Buddhist meditative practice of _samatha_, refining one's attention and metacognition, to create a kind of telescope to examine the space of the mind. Drawing on the work of the physicist John Wheeler, he then proposes a more general theory in which the participatory nature of reality is envisioned as a self-excited circuit. In comparing these ideas to the Buddhist theory known as the Middle Way philosophy, Wallace explores further aspects of his "general theory of ontological relativity," which can be investigated by means of _vipasyana_, or insight, meditation. Wallace then focuses on the theme of symmetry in reference to quantum cosmology and the "problem of frozen time," relating these issues to the theory and practices of the Great Perfection school of Tibetan Buddhism. He concludes with a discussion of the general theme of complementarity as it relates to science and religion. The theories of relativity and quantum mechanics were major achievements in the physical sciences, and the theory of evolution has had an equally deep impact on the life sciences. However, rigorous scientific methods do not yet exist to observe mental phenomena, and naturalism has its limits for shedding light on the workings of the mind. A pioneer of modern consciousness research, Wallace offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physicists and philosophers with the time-honored meditative traditions of Buddhism.

Some of the most eminent and enduring philosophical questions concern matters of priority: what is prior to what? What 'grounds' what? Is, for instance, matter prior to mind? Recently, a vivid debate has arisen about how such questions have to be understood. Can the relevant notion or notions of priority be spelled out? And how do they relate to other metaphysical notions, such as modality, truth-making or essence? This volume of new essays, by leading figures in contemporary metaphysics, is the (...) first to address and investigate the metaphysical idea that certain facts are grounded in other facts. An introduction introduces and surveys the debate, examining its history as well as its central systematic aspects. The volume will be of wide interest to students and scholars of metaphysics.

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use in other (...) populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

The article is primarily concerned with the notion of a truth-maker. An explication for this notion is offered, which relates it to other notions of making something such-and-such. In particular, it is shown that the notion of a truth-maker is a close relative of a concept employed by van Inwagen in the formulation of his Consequence Argument. This circumstance helps understanding the general mechanisms of the concepts involved. Thus, a schematic explication of a whole battery of related notions is offered. (...) It is based on an explanatory notion, introduced by the sentential connector “because”, whose function is examined in some detail. Finally, on the basis of the explication proposed, an argument is developed to the effect that the objects usually regarded as truth-makers are not apt to play this role. (shrink)

In spite of its significance for everyday and philosophical discourse, the explanatory connective has not received much treatment in the philosophy of logic. The present paper develops a logic for based on systematic connections between and the truth-functional connectives.

The paper deals with the notions of grounding and of existential dependence. It is shown that cases of existential dependence seem to be systematically correlated to cases of grounding and hence the question is raised what sort of tie might hold the two notions together so as to account for the observed correlation. The paper focusses on three possible ties between grounding and existential dependence: identity, definition, and grounding. A case for the definitional tie is made.

The main contribution of this paper is a novel account of ontological dependence. While dependence is often explained in terms of modality and existence, there are relations of dependence that slip through the mesh of such an account. Starting from an idea proposed by Jonathan Lowe, the article develops an account of ontological dependence based on a notion of explanation; on its basis, certain relations of dependence can be established that cannot be accounted by the modal-existential account. Dependence is only (...) one of two main topics of this paper, for it is approached via a discussion of the category of substance. On a traditional view, substances can be characterised as independent entities. Before the background of a modal-existential account of dependence, this idea appears problematic. The proposed notion of explanatory dependence is shown to vindicate the traditional approach to substance. (shrink)

The argument for modal collapse is partly responsible for the widespread rejection of the so-called Principle of Sufficient Reason in recent times. This paper discusses the PSR against the background of the recent debate about grounding and develops principled reasons for rejecting the argument from modal collapse.

reality is a complex affair. It comprises a huge variety of different elements. Importantly, though, reality is not a mere aggregate of its elements but rather a structured whole or system whose building blocks are not all on the same level. Instead, they form hierarchical networks ordered by relations of priority. In such networks, derivative aspects of reality obtain in virtue of their grounds, that is, in virtue of more fundamental aspects of reality that are prior to them.This picture of (...) reality as a structured whole is currently enjoying a renaissance in the works of philosophers such as Kit Fine, Jonathan Schaffer, and many others. But far from being a new picture, it has been widely endorsed throughout the... (shrink)

In Metaphysics of States of Affairs, Bo Meinertsen reviews and works out several underdeveloped points in the existing scholarly debate on states of affairs, and presents his own original account in detail. In this paper, we raise three problems for Meinertsen’s account and draw attention to an alternative view that, though not discussed in the book, is not beset by these problems.

The article discusses an idea of how to extend the notion of rigidity to predicates, namely the idea that predicates stand in a certain systematic semantic relation to properties, such that this relation may hold rigidly or nonrigidly. The relation (which I call signification) can be characterised by recourse to canonical property designators which are derived from predicates (or general terms) by means of nominalization: a predicate signifies that property which the derived property designator designates. Whether signification divides into rigid (...) and non-rigid cases will then depend uponwhether canonical property designators divide into rigid and non-rigid ones. But, I shall argue, they do not, and so the only notion of rigidity gained this way is trivial. To show this, I first focus on the kind of canonical property designators which could be thought to be nonrigid, canonical designators such as having the colour of ripe tomatoes which themselves contain non-rigid property designators. An argument to the effect that such complex canonical designators are non-rigid is rebutted, five arguments to the effect that they are rigid are formulated, and finally an explanation of their rigidity based on the general nature of canonical property designators is presented.

The essay is a partial investigation into the semantics of the explanatory connective ‘because’. After three independently plausible assumptions about ‘because’ are presented in some detail, it is shown how their interaction generates a puzzle about ‘because’, once they are combined with a common view on conceptual analysis. Four possible solutions to the puzzle are considered.

ld English manors have their ghosts. And though I would not want to call analytic philosophy a ‘manor’, nor exactly ‘old’, it certainly is of some decent English origin, and it left adolescence a while ago. No wonder then, that it is not exempt from haunting terrors. One particular spectre has been haunting it for decades; it already gave some analytic pioneers the creeps, and we still now and then find people terrified by it: the ghost of old Bradley has (...) not yet found its rest and keeps on threatening people with his notorious regress. The present essay is a lecture in exorcism; much of the fear old Bradley spread, so I will argue, peters out once we dare to look it in the eye. However, this essay is not primarily exegetical, and especially not an attempt in interpreting Bradley. I find Bradley’s writings, to say the least, not particularly accessible. Discussions of isolated passages from his longer treatises will probably be less fruitful than a careful study of the positions within the whole argumentative structure, supplied by the examination of Bradley’s intellectual upcoming. His treatments on relations and properties, in which he develops the famous regress argument, are motivated by a radical goal: a vindication of some form of monism. To reach this goal, he tries to deconstruct the most basic categories of our ordinary conceptual framework. Thus, he holds that.. (shrink)

Fictional realism, i.e., the view that because fictions exist, fictional characters exist as well, has recently been accused of leading to inconsistency generated by phenomena of indeterminacy and inconsistency in fiction. We examine in detail four arguments against fictional realism, and present a version of fictional realism which can withstand those arguments.

It is shown that the standard definitions of truth-functionality, though useful for their purposes, ignore some aspects of the usual informal characterisations of truth-functionality. An alternative definition is given that results in a stronger notion which pays attention to those aspects.

I develop a new argument for an expressivist account of epistemic modals, which starts from a puzzle about epistemic modals which Seth Yalcin recently presented. I reject Yalcin's own solution to the puzzle, and give a better explanation based on expressivism concerning epistemic modals. I also address two alleged problems for expressivism: do embeddings of epistemic modals pose a serious threat to expressivism, and how can expressivism account for disagreements about statements containing epistemic modals?

Gaskin's book The Unity of the Proposition is very rich in material. I will focus only on its central thesis: Gaskin holds that Bradley's regress (more precisely, one particular version of it) is not only innocent, but in fact philosophically significant because it plays a crucial role in solving what Gaskin calls the problem of the unity of the proposition . In what follows, I first explain what that problem is meant to be ( section 1 ), then I present (...) and criticise Gaskin's proposal about how Bradley's regress bears on the problem ( section 2 ), and finally I sketch an alternative approach to the problem ( section 3 ).

The paper focusses on two claims about metaphysical structure: Atomism and Fundamentalism. The first of these claims says that there are mereological atoms, i.e. minimal elements in the mereological structure of reality. The second says that there are fundamental truths, i.e. minimal elements in the grounding structure of reality. A philosopher who defended both of these claims was Bernard Bolzano; the present paper is an exploration of his views on the matter.

The main question of this paper is how to understand the notion of a truth-maker. In section 1, I show that the identification of truth-making with necessitation cannot capture the pretheoretic understanding of notions such as ‘x makes something true’. In section 2, I examine Barry Smith’s reaction to this problem: he defines truth-making as the combination of necessitation and projection. I focus on the formal part of Smith’s account, which is shown to yield undesired results. However, in section 3, (...) I present an alternative account of projection, which fares better and can fruitfully be employed to circumvent the problems raised in section 1. Unfortunately, the account still has to face some troublemakers, as I show in the final section. I conclude, therefore, with a pessimistic view on the project of defining truth-making via necessitation and projection. (shrink)

Bringing together Deleuze, Blanchot, and Foucault, this book provides a detailed and original exploration of the ideas that influenced Deleuze's thought leading up to and throughout his cinema volumes and, as a result, proposes a new definition of art. Examining Blanchot's suggestion that art and dream are "outside" of power, as imagination has neither reality nor truth, and Foucault's theory that power forms knowledge by valuing life, Eugene Brent Young relates these to both Deleuze's philosophy of time and his work (...) with Guattari on art. In doing so, he uses case studies from literature and popular film, including Kafka's Castle, Villeneuve's Arrival, and Kubrick's Eyes Wide Shut. Providing important new insights for those working in literary and cinematic studies, this book advances a new definition of art as that which reverses the realities and truths of power to express obscure ideas and values beyond both our exterior and interior worlds.

The semantic rules that govern ordinary property discourse appear to give rise to a version of Russell's antinomy. Do we therefore have an inconsistent conception of properties? This paper firstly develops a consistent conception of properties and secondly argues that we may indeed interpret ordinary property discourse as expressing the consistent conception rather than an inconsistent one.

This paper investigates the distinction between determining and modifying expressions that played an important role in the Brentano School. The focus lies on how the distinction is applied to adjectives by Anton Marty and Kazimierz Twardowski. In ‘heavy gun’, ‘heavy’ plays a determining role: heavy guns are guns; in ‘fake gun’, ‘fake’ plays a modifying role: fake guns are no guns at all. According to Marty and Twardowski, when a modifying adjective is combined with a noun, it shifts the meaning (...) of the noun. This paper rejects this proposal and proposes a better account which was developed by Bernard Bolzano: the difference between determining and modifying adjectives must be understood in terms of how their meanings figure in meaning analyses of adjective-noun combinations.

Philosophers of mathematics commonly distinguish between explanatory and non-explanatory proofs. An important subclass of mathematical proofs are proofs by induction. Are they explanatory? This paper addresses the question, based on general principles about explanation. First, a recent argument for a negative answer is discussed and rebutted. Second, a case is made for a qualified positive take on the issue.

The late Jacob Klein’s important book is, remarkably, a lucid presentation of esoteric argument. Dealing with the famed Platonic triad, Theaetetus, Sophist, and Statesman, Klein settles the dispute about the missing dialogue, "The Philosopher," by first denying that it is missing and second showing that it is unnecessary. He argues, in short, that the triad is a dyad. That argument is reinforced by the distinction Klein strongly implies between the Socratic Theaetetus and the Eleatic Sophist and Statesman. "We can now (...) understand why the conversations of the ‘trilogy’ occur in two, not three, days and why the Sophist, the Statesman, and the Philosopher are dealt with in two, not three, dialogues".

In this paper, we will discuss Peter van Inwagen’s contribution to the epistemological debate about revealed peer disagreement. Roughly, this debate focuses on situations in which at least two participants disagree on a certain proposition based on the same evidence. This leads to the problem of how one should react rationally when peer disagreement is revealed. Van Inwagen, as we will show, discusses four possible reactions, all of which he rejects as unsatisfying. Our proposal will be to point to hidden (...) assumptions in van Inwagen’s reasoning and ask whether he is willing to reject at least one of these to get rid of the problem. In short, our thesis amounts to the following: Of the two epistemological claims, which we call “Weak” and “Full-blown Fallibilism”, van Inwagen cannot simultaneously accept the first and reject the latter, while this is what he seems to suggest. Revealing this potential dilemma for van Inwagen’s position will lead to a more detailed discussion of how “rationality”, “truth”, “evidence” and “justification” interrelate and how a closer look at their relation might help solving the puzzle of revealed peer disagreement.

Reference to properties is normally achieved by the use of nominalizations of predicative expressions. I examine the relation between different kinds of these: while, traditionally, the terms 'wisdom' and 'the property of being wise' were thought to be co-referential, in certain contexts they do not seem to be interchangeable salva veritate. Observing this, Friederike Moltmann claims that abstract nouns such as 'wisdom' do not refer to properties. I argue that her theory is flawed and that the existence of the problematic (...) contexts should be explained in non-referential terms. (shrink)

What does it mean that some proposition follows from others? The standard way of spelling out the notion proceeds in modal terms: x follows from y iff necessarily, if y is true, so is x. But although this yields a useful and manageable account of consequence, it fails to capture certain aspects of our pre-theoretical understanding of consequence. In this paper, an alternative notion of logical consequence, based on the idea of grounding, is developed.

The paper is a detailed reconstruction of Bernard Bolzano’s account of merely possible objects. According to Bolzano, there are some objects which are merely possible. They are neither denizens of space and time nor members of the causal order, but they could have been so. Examples are merely possible persons, mountains etc., objects which are neither actual nor persons or mountains, but which could have been both. Bolzano’s views are contrasted with the theory of Alexius Meinong, and it is shown (...) that they have a modern counterpart in the accounts of merely possible objects that were developed by Bernard Linsky & Ed Zalta, and by Timothy Williamson.

For philosophers interested in ontological issues, the writings of the important figures of Austrian philosophy in the nineteenth and early twentieth century contain many buried treasures to rediscover. Bernard Bolzano, Franz Brentano, Alexius Meinong, and Edmund Husserl, to name just four grand names of that period, were highly aware of the importance of a feasible ontology for many of the philosophical questions they addressed throughout their works.

This Paper is an Exploration of Bolzano’s views on causation, which have not been thoroughly examined yet. The paper reconstructs Bolzano’s position, with a focus on his analysis of the concept of causation, on its ontological presuppositions, and on how he relates causation to his theory of grounding.1 A comparison with standard positions from the contemporary debate on causation will prove his views to be quite original. Moreover, they are a valuable addition to the more recent debate on metaphysical grounding,2 (...) in which grounding is sometimes informally described as something like metaphysical causation with the exact connection of the two notions seldom being elaborated. Bolzano’s theory explicitly addresses .. (shrink)

The Conjunction Principle says, roughly, that if the truth of a conjunction can be brought about, then the truth of each conjunct can be brought about. The current essay argues that this principle is not valid. After a clarification of the principle, it is shown how a proper understanding of the involved notions falsify the principle. As a corollary, a recent attack on van Inwagen’s Consequence Argument will be rebutted, because it relies on the invalid conjunction principle.

In my paper I am concerned with Peter van Inwagen's Consequence Argument. I focus on its probably best known version. In this form it crucially employs the notion of rendering a proposition false, anotion that has never been made sufficiently clear. The main aim of my paper is to shed light on thisnotion. The explications offered so far in thedebate all are based on modal concepts. Iargue that for sufficient results a ``stronger'', hyper-intensional concept is needed, namely the concept expressed (...) by the word ``because''. I show that my analysis is superior to the prior ones. On the basis of this analysis I further explain why van Inwagen''s argument fails. (shrink)

The paper has two main objectives: first, it presents a new argument against the so-called Anscombe Thesis (if χ φ-s by ψ-ing, then χ's φ-ing = χ's ψ-ing). Second, it develops a proposal about the syntax and semantics of the 'by'-locution.
