This paper introduces Exclusion Logic - a simple modal logic without negation or disjunction. We show that this logic has an efficient decision procedure. We describe how Exclusion Logic can be used as a deontic logic. We compare this deontic logic with Standard Deontic Logic and with more syntactically restricted logics.

In the Principles of Philosophy, Descartes attempts to explicate the well-known phenomena of varying bodily size through an appeal to the concept of "solidity," a notion that roughly corresponds to our present-day concept of density. Descartes' interest in these issues can be partially traced to the need to define clearly the role of matter in his natural laws, a problem particularly acute for the application of his conservation principle. Specifically, since Descartes insists that a body's "quantity of motion," defined as (...) the product of its "size" and speed, is conserved in all material interactions, it is imperative that he explain how solidity influences the magnitude of this force. As a means of resolving this problem, Descartes postulated an idealized condition of "perfect solidity" which correlates a body's "agitation" force (a forerunner of Newton's concept of non-accelerating, or "inertial" motion) with the interplay of its volume, surface area, and composition of minute particles. This essay explores this often misunderstood aspect of Descartes' physics, as well as the special function of idealized conditions in his collision rules. Contrary to those commentators who regard "perfect solidity" as a stipulation on bodily impact, this notion, it will be argued, is primarily concerned with the internal composition of macroscopic bodies, and only indirectly with their collision characteristics. Along the way, many of Descartes' hypotheses will be shown to display a level of sophistication and intricacy that, despite their essential incompatibility, belie several of the common misconceptions of Cartesian science.

There is a fundamental incompatibility between a developmental orientation to education and instrumental and scientistic conceptions of rationality that dominate educational inquiry. An expanded conception of rationality is provided in the critical theory of Jurgen Habermas. This study draws on Habermas' work to present a theory of inquiry that is consistent with a developmental perspective. I distinguish three interdependent realms of experience--the objective world of nature, the intersubjective world of society and the subjective world of each individual. Then, I (...) argue that current conceptions of rationality tend to reduce personal and interpersonal experience to the objective material realm. Under prevailing conceptions, human action is rational when it pursues valued ends guided by knowledge about the world and effective means-ends relationships. Both theories of knowledge and theories of value in these conceptions are inadequate for a developmental orientation. -/- First, knowledge is defined as justified true belief. Theories of truth are based on the correspondence of beliefs with an external world; theories of justification are based on perceptual certainty. These conceptions objectify experience by making experience an object of natural science and instrumental action separate from and external to the person. Such conceptions reduce experience to the objective material dimension and cannot adequately account for the personal and interpersonal dimensions of human experience and understanding. -/- Second, because value claims are not capable of justification by these standards, they are considered ultimately irrational and treated as subjectively held empirical properties of individuals. The only standard of rationality is efficiency and economy in the selection of means. Ethics is reduced to empirical science. But the removal of practical questions from public discourse divests action of ethical significance. With its strict separation of descriptive and normative domains, empirical-analytic inquiry can neither acknowledge its standard of instrumental efficiency nor reach into the practical arena to guide the selection of values and ends that orient and gude human action. Practical questions that cannot be framed in terms of technical problems cannot be taken seriously. -/- Whereas these conceptions of rationality are generally derived from theories of experienced based on individual consciousness, Habermas looks to language for a more adequate account of the intersubjective nature of experience. This account provides an expanded conception of rationality with theories for justifying beliefs and actions that incorporate the personal and interpersonal dimensions of experience so critical to a developmental perspective. Through an analysis of the universal pragmatic structure of language directed to the resolution of problematic truth claims and moral claims, this study presents a consensus theory of truth (for a more adequate theory of knowledge) and a communicative theory of ethics (based on a more adequate theory of human values). -/- The concept of truth refers to a universal pragmatic convention of the unforced agreement of an ideal community of inquirers. Ethical conduct is guided by norms that reflect a rational general will and that regulate genuine human needs. Problematic truth claims and moral claims are discursively justified by the force of the better argument under the conditions of an anticipated "ideal speech situation" inherent in the very structure of communication. Furthermore, a theory of inquiry is developed in which inquiry processes are represented as historically evolved extensions of developmental process in the three realms of experience. Three interrelated forms of inquiry are derived--empirical-analytic, hermeneutic and critical. I derive each from its respective experiential realm, and indicate the logic of inquiry, object domain, and kind of knowledge gained from each. -/- An exploration of the relationship between inquiry and development provides a foundation for a developmental orientation to education. Finally, the theory is contrasted with prevailing inquiry approaches in education and illustrated with an application to a particular educational problem. (shrink)

Phenomenology is the study of appearance as such. It is a branch of both Ontology and Epistemology, since appearing is being known. By an ‘appearance’ is meant any existent which impinges on consciousness, anything cognized, irrespective of any judgment as to whether it be ‘real’ or ‘illusory.’ The evaluation of a particular appearance as a reality or an illusion is a complex process, involving inductive and deductive logical principles and activities. Opinion has to earn the status of strict knowledge. Knowledge (...) develops from appearances, which may be: (a) objects of perception, i.e. concrete phenomena in the physical or mental domains; (b) objects of intuition, i.e. one’s subjective self, cognitions, volitions and valuations (non-phenomenal concretes); and/or (c) objects of conception, i.e. simple or complex abstracts of preceding appearances. Abstraction relies on apprehensions of sameness and difference between appearances (including received or projected appearances, and projected negations of appearances). Coherence in knowledge (perceptual, intuitive and conceptual) is maintained by apprehensions of compatibility or incompatibility. Words facilitate our construction of conceptual knowledge, thanks to their intentionality. The abstract concepts most words intend are common characters or behaviors of particulars (concrete material, mental or subjective experiences). Granting everything in the world is reducible to waves, ‘universals’ would be equalities or proportionalities in the measures of the features, motions and interrelations of particular waves. Such a theory of universals would elucidate sensation and memory. In attempting to retrace the development of conceptual knowledge from experience, we may refer to certain major organizing principles. It is also important to keep track of the order of things in such development, interrelating specific concepts and specific experiences. By proposing a precise sequence of events, we avoid certain logical fallacies and are challenged to try and answer certain crucial questions in more detail. Many more topics are discussed in the present collection of essays, including selfhood, adduction and other logical issues, the status of mathematical concepts and theology. (shrink)

Those sympathetic to the naturalistic side of James hope that his critique of ‘philosophical materialism’ can be separated from those elements of his thinking that are essential to his pragmatism. Such a separation is possible once we see that James’s critique of materialism grows out of his views about its incompatibility with the existence of objective values. Objective values (as James understands them) are incompatible, however, not with materialism in its most general form, but rather with materialism that understood (...) the ‘material world’ in terms of the sciences of the late nineteen hundreds. In particular, one could not defend the potential objectivity of value in the way that James hoped if one endorsed the particular ‘pessimistic’ cosmology characteristic of the sciences at the turn of the last century. Consequently, if one rejects certain ‘empirical assumptions’ associated with the science of James’s day, the possibility of a type of ‘melioristic materialism’ opens up, and this sort of materialist could still understand value in the way that James proposes.

This paper investigates Péter Pázmány’s theory of mixtures from his exegesis of Meteorologica IV, in the context of sixteenth-century scholarship on Aristotle’s Meteorologica. It aims to contribute to a discussion of Anneliese Maier’s thesis concerning the incompatibility between hylomorphism and the theory of elements in the Aristotelian tradition. It presents two problems: the placement of Meteorologica IV in the Jesuit cursus on physics and the conceptualization of putrefaction as a type of substantial mutation. Through an analysis of these issues, (...) it shows how sixteenth-century exegesis imposes the hylomorphic thesis onto the subject matter of meteorology and how the hylomorphic theory of substantial change can be adapted in order to accommodate the theory of elements. The case being made is that Meteorologica is a privileged place where hylomorphism and the theory of elements meet and that the late Aristotelian theory of mixtures sought to accommodate both theories of material substance.

Religious pluralism is the view that more than one religion is correct, and that no religion enjoys a special status in relation to the ultimate. Yet the world religions appear to be incompatible. How, then, can more than one be correct? Discussions and critiques of religious pluralism usually focus on the work of John Hick, yet there are a number of other pluralists whose responses to this incompatibility problem are importantly different from Hick’s. This article surveys the solutions of (...) Hick, Harrison, Heim, Byrne, and Knitter to the incompatibility problem. I conclude that, while none of these views is without weakness, there are several promising pluralist solutions to this problem. Moreover, confessionalists (i.e. exclusivists and inclusivists) must also address issues related to incompatibility. (shrink)

In this paper, I discuss the analysis of logic in the pragmatic approach recently proposed by Brandom. I consider different consequence relations, formalized by classical, intuitionistic and linear logic, and I will argue that the formal theory developed by Brandom, even if provides powerful foundational insights on the relationship between logic and discursive practices, cannot account for important reasoning patterns represented by non-monotonic or resource-sensitive inferences. Then, I will present an incompatibility semantics in the framework of linear logic which (...) allow to refine Brandom’s concept of defeasible inference and to account for those non-monotonic and relevant inferences that are expressible in linear logic. Moreover, I will suggest an interpretation of discursive practices based on an abstract notion of agreement on what counts as a reason which is deeply connected with linear logic semantics. (shrink)

Are the following propositions true of the colors: No object can be more than one determinable or determinate color all over at the same time (Incompatibility); the colors of objects are mind-independent (Objectivism); and most human observers usually perceive the colors of objects veridically in typical conditions (Veridicality)? One reason to think not is that the empirical literature appears to support the proposition that there is mass perceptual disagreement about the colors of objects amongst human observers in typical conditions (...) (P-Disagreement). In this article, we defend Incompatibility, Objectivism, and Veridicality by calling into question whether the empirical literature really supports P-Disagreement. (shrink)

John D. Norton is responsible for a number of influential views in contemporary philosophy of science. This paper will discuss two of them. The material theory of induction claims that inductive arguments are ultimately justified by their material features, not their formal features. Thus, while a deductive argument can be valid irrespective of the content of the propositions that make up the argument, an inductive argument about, say, apples, will be justified (or not) depending on facts about apples. (...) The argument view of thought experiments claims that thought experiments are arguments, and that they function epistemically however arguments do. These two views have generated a great deal of discussion, although there hasn’t been much written about their combination. I argue that despite some interesting harmonies, there is a serious tension between them. I consider several options for easing this tension, before suggesting a set of changes to the argument view that I take to be consistent with Norton’s fundamental philosophical commitments, and which retain what seems intuitively correct about the argument view. These changes require that we move away from a unitary epistemology of thought experiments and towards a more pluralist position. (shrink)

In this paper we present a new metaphysical theory of material objects. On our theory, objects are bundles of property instances, where those properties give the nature or essence of that object. We call the theory essential bundle theory. Property possession is not analysed as bundle-membership, as in traditional bundle theories, since accidental properties are not included in the object’s bundle. We have a different story to tell about accidental property possession. This move reaps many benefits. Essential bundle theory (...) delivers a simple theory of the essential properties of material objects; an explanation of how object coincidence can arise; an actual-world ground for modal differences between coincident objects; a simple story about intrinsic properties; and a plausible account of certain ubiquitous cases of causal overdetermination.

I examine to what extent accounts of mechanisms based on formal interventionist theories of causality can adequately represent biological mechanisms with complex dynamics. Using a differential equation model for a circadian clock mechanism as an example, I first show that there exists an iterative solution that can be interpreted as a structural causal model. Thus, in principle it is possible to integrate causal difference-making information with dynamical information. However, the differential equation model itself lacks the right modularity properties for a (...) full integration. A formal mechanistic model will therefore either have to leave out non-causal or causal explanatory relations. (shrink)

John Norton says that philosophers have been led astray for thousands of years by their attempt to treat induction formally. He is correct that such an attempt has caused no end of trouble, but he is wrong about the history. There is a rich tradition of non-formal induction. In fact, material theories of induction prevailed all through antiquity and from the Renaissance to the mid-1800s. Recovering these past systems would not only fill lacunae in Norton’s own theory but would (...) highlight areas where Norton has not freed himself from the straightjacket of formal induction as much as he might think. This essay begins that recovery. (shrink)

The Christian doctrine of the Trinity poses a serious philosophical problem. On the one hand, it seems to imply that there is exactly one divine being; on the other hand, it seems to imply that there are three. There is another well-known philosophical problem that presents us with a similar sort of tension: the problem of material constitution. We argue in this paper that a relatively neglected solution to the problem of material constitution can be developed into a (...) novel solution to the problem of the Trinity. (shrink)

The aim of the present work is to demonstrate that physicalism and a priori knowledge are epistemologically incompatible. The possibility of a priori knowledge on physicalism will be considered in the light of Edmund Gettier’s insight regarding knowledge. In the end, it becomes apparent that physicalism entails an unavoidable disconnect between a priori beliefs and their justificatory grounds; thus precluding the possibility of a priori knowledge. Consequently, a priori knowledge and physicalism are epistemologically incompatible.

There has been much discussion recently of what has been labeled the “Brown-Boghossian-McKinsey”, “Brown-McKinsey” or sometimes just “McKinsey” arguments for the incompatibility of externalism and self-knowledge. However, while the three author's arguments have been treated as interchangeable, they are not identical. In particular, Brown’s and Boghossian’s arguments have a fairly serious flaw that cannot so easily be attributed to McKinsey. In what follows, I’ll (1) present a version of the ‘received’ “Brown-Boghossian-McKinsey” argument, (2) outline what I take to be (...) the most serious objection to it, (3) explain why this sort of objection does not seem, or do not seem immediately, to tell against McKinsey’s argument, and (4) suggest a number of alternative responses that might apply to McKinsey as well.

Relationalism is a view popularized by Cohen according to which the colors are relational properties. Cohen’s view has the unintuitive consequence that the following propositions are false: (i) no object can be more than one determinate or determinable color all over at the same time; (ii) ordinary illusion cases occur whenever the color perceptually represented conflicts, according to (i) above, with the object’s real color; and (iii) the colors we perceive obey (i). I investigate Cohen’s attempt to address these intuitive (...) propositions with which his view struggles and find it to be incompatible with how he motivates his view. (shrink)

The idea of “material plenitude” has been gaining traction in recent discussions of the metaphysics of material objects. My main goal here is to show that this idea may have important dialectical implications for the metaphysics of properties – more specifically, that it provides nominalists with new resources in their attempt to reject an ontology of universals. I will recapitulate one of the main arguments against nominalism – due to David Armstrong – and show how plenitude helps the (...) nominalist overcome the argument. (shrink)

Are the sculpture and the mass of gold which permanently makes it up one object or two? In this article, we argue that the monist, who answers ‘one object’, cannot accommodate the asymmetry of material constitution. To say ‘the mass of gold materially constitutes the sculpture, whereas the sculpture does not materially constitute the mass of gold’, the monist must treat ‘materially constitutes’ as an Abelardian predicate, whose denotation is sensitive to the linguistic context in which it appears. We (...) motivate this approach in terms of modal analyses of material constitution, but argue that ultimately it fails. The monist must instead accept a deflationary, symmetrical use of ‘materially constitutes’. We argue that this is a serious cost for her approach. (shrink)

Philosophical dialetheism, whose main exponent is Graham Priest, claims that some contradictions hold, are true, and it is rational to accept and assert them. Such a position is naturally portrayed as a challenge to the Law of Non-Contradiction (LNC). But all the classic formulations of the LNC are, in a sense, not questioned by a typical dialetheist, since she is (cheerfully) required to accept them by her own theory. The goal of this paper is to develop a formulation of the (...) Law which appears to be unquestionable, in the sense that the Priestian dialetheist is committed to accept it without also accepting something inconsistent with it, on pain of trivialism—that is to say, on pain of lapsing into the position according to which everything is the case. This will be achieved via (a) a discussion of Priest's dialetheic treatment of the notions of rejection and denial; and (b) the characterization of a negation via the primitive intuition of content exclusion. Such a result will not constitute a cheap victory for the friends of consistency. We may just learn that different things have been historically conflated under the label of 'Law of Non-Contradiction'; that dialetheists rightly attack some formulations of the Law, and orthodox logicians and philosophers have been mistaken in assimilating them to the indisputable one.

This article offers a novel solution to the problem of material constitution: by including non-concrete objects among the parts of material objects, we can avoid having a statue and its constituent piece of clay composed of all the same proper parts. Non-concrete objects—objects that aren’t concrete, but possibly are—have been used in defense of the claim that everything necessarily exists. But the account offered shows that non-concreta are independently useful in other domains as well. The resulting view falls (...) under a ‘nonmaterial partist’ class of views that includes, in particular, Laurie Paul’s and Kathrin Koslicki’s constitution views; ones where material objects have properties or structures as parts respectively. The article gives reasons for preferring the non-concretist solution over these other non-material partist views and defends it against objections. (shrink)

In metaphysics, the view that material constitution is transitive is ubiquitous, an assumption expressed by both proponents and critics of constitution views. Likewise, it is typically assumed within the philosophy of mind that physical realization is a transitive relation. In both cases, this assumption of transitivity plays a role in discussion of the broader implications of a metaphysics that invokes either relation. Here I provide reasons for questioning this assumption and the uses to which this appeal to transitivity is (...) put. As my title suggests, I shall focus on the case of material constitution, using a brief discussion of realization at the outset to motivate the discussion of the transitivity of material constitution at the core of the paper.

Humans leverage material forms for unique cognitive purposes: We recruit and incorporate them into our cognitive system, exploit them to accumulate and distribute cognitive effort, and use them to recreate phenotypic change in new individuals and generations. These purposes are exemplified by writing, a relatively recent tool that has become highly adept at eliciting specific psychological and behavioral responses in its users, capability it achieved by changing in ways that facilitated, accumulated, and distributed incremental behavioral and psychological change between (...) individuals and generations. Writing is described here as a self-organizing system whose design features reflect points of maximal usefulness that emerged under sustained collective use of the tool. Such self-organization may hold insights applicable to human cognitive evolution and tool use more generally. Accordingly, this article examines the emergence of the ability to leverage material forms for cognitive purposes, using the tool-using behaviors and lithic technologies of ancestral species and contemporary non-human primates as proxies for matters like collective use, generational sustainment, and the non-teleological emergence of design features.

In this chapter, I show that there is at least one crucial, non-short, argument, which does not involve arguments about spatiotemporality, why Kant’s subjectivism about the possibility of knowledge, argued in the Transcendental Deduction, must lead to idealism. This has to do with the fact that given the implications of the discursivity thesis, namely, that the domain of possible determination of objects is characterised by limitation, judgements of experience can never reach the completely determined individual, i.e. the thing in itself (...) or the unlimited real, but only objects as objects of possible experience. As such, it can be shown by reference to a key argument from Kant, that Hegel’s famous criticism that Kant is not licensed, on the basis of his core arguments concerning the original-synthetic unity of apperception, to restrict our knowledge to appearances, is mistaken on purely systematic grounds. More specifically, I argue that idealism follows already from the constraints that the use of the categories, in particular the categories of quality, places on the very conceivability of things in themselves. My claim is that, although it is not only possible but also necessary to think things in themselves, it does not follow that by merely thinking them we have a full grasp of the nature of things in themselves, as some important commentators claim we have. We must therefore distinguish between two kinds of conceiving of things in themselves: conceiving in the standard sense of ‘forming the notion of’, and conceiving in the narrow sense of ‘having a determinate intellectual grasp’. So although we must be able notionally to think things in themselves, as the grounds of their appearances, we cannot even conceive, through pure concepts, of how they are in themselves in any determinate, even if merely intellectual, sense. To put it differently, we cannot have a positive conception of things in themselves (this is in line with Kant’s distinction between noumena in the negative and positive senses; cf. B307–9). For support, I resort to a much overlooked chapter in the Critique, concerning the transcendental Ideal, where Kant discusses what it is for a thing to be a thing in itself proper, namely, something that is thoroughly determined. This concerns the real ontological conditions of things, which are not satisfied by the modal categories alone, namely, their existence conditions. I claim that the chief reason why, given Kant’s view of determinative judgement, we cannot determine a thing in itself is because of two connected reasons: (1) a thing in itself is already fully determined and therefore not further determinable and (2) we cannot possibly determine all of the thing’s possible determinations. In this context, I also discuss the notion of material (not: empirical) synthesis—of which Kant speaks in the chapter on the transcendental Ideal—which must be presupposed as the ground of the formal a priori synthesis that grounds possible experience. This material synthesis, which is an idea of reason that defines a thing as thoroughly determined with regard to all of its possible predicates and has mere regulative status, can by implication not be determined by the forms of the understanding, which synthesise only a limited set of predicates. As a result, given this definition of ‘thing in itself’, any object (appearance) as at best44 a limited set of determinations of the thing can never be numerically identical to the thing in itself as thoroughly determined individual. This undercuts a standard assumption about the identity relation between appearances and things in themselves in many contemporary interpretations of Kant’s transcendental idealism. (shrink)

This paper poses a problem of promiscuity for views that endorse material constitution as a metaphysic relation.

Embodied human minds operate in and spread across a vast and uneven world of things—artifacts, technologies, and institutions which they have collectively constructed and maintained through cultural and individual history. This chapter seeks to add a historical dimension to the enthusiastically future-oriented study of “natural-born cyborgs” in the philosophy of cognitive science,3 and a cognitive dimension to recent work on material memories and symbol systems in early modern England, bringing humoral psychophysiology together with material culture studies. The aim (...) is to sketch an integrative framework which spans early modern ideas and practices relating to brains, bodies, memory, and objects. Embodiment and environment, I’ll argue, were not (always) merely external influences on feeling, thinking, and remembering, but (in certain circumstances) partly constitutive of these activities.

How do archaeologists make effective use of physical traces and material culture as repositories of evidence? Material Evidence is a collection of 19 essays that take a resolutely case-based approach to this question, exploring key instances of exemplary practice, instructive failures, and innovative developments in the use of archaeological data as evidence. The goal is to bring to the surface the wisdom of practice, teasing out norms of archaeological reasoning from evidence. -/- Archaeologists make compelling use of an (...) enormously diverse range of material evidence, from garbage dumps to monuments, from finely crafted artifacts rich with cultural significance to the inadvertent transformation of landscapes over the long term. Each contributor to Material Evidence identifies a particular type of evidence with which they grapple and considers, with reference to concrete examples, how archaeologists construct evidential claims, critically assess them, and bring them to bear on pivotal questions about the cultural past. -/- Historians, cultural anthropologists, philosophers, and science studies scholars are increasingly interested in working with material "things" as objects of inquiry and as evidence – and they acknowledge on all sides just how challenging this is. One of the central messages of the book is that close analysis of archaeological best practice can yield constructive guidelines for practice that have much to offer practitioners within archaeology and well beyond.

Are materially constituted entities, such as statues and glasses of liquid, something more than their material constituents? The puzzle that frames this paper stems from conflicting answers to this question. At the core of the paper is a distinctive way of thinking about material constitution that posits two concepts of constitution, compositional and ampliative constitution, with the bulk of the discussion devoted to developing distinct analyses for these concepts. Distinguishing these concepts solves our initial puzzle and enriches the (...) space of possibilities for constitution views. (shrink)

Some philosophers, like David Chalmers, have either shown their sympathy for, or explicitly endorsed, the following two principles: Panpsychism—roughly the thesis that the mind is ubiquitous throughout the universe—and Organizational Invariantism—the principle that holds that two systems with the same fine-grained functional organization will have qualitatively identical experiences. The purpose of this paper is to show the tension between the arguments that back up both principles. This tension should lead, or so I will argue, defenders of one of the principles (...) to give up on the other. (shrink)

Although the relationship between faith and intellectual humility has yet to be specifically addressed in the philosophical literature, there are reasons to believe that they are at least in some sense incompatible, especially when judging from pre-theoretical intuitions. In this paper I attempt to specify and explicate this incompatibility, which is found in specific conflicting epistemic attitudes they each respectively invite. I first suggest general definitions of both faith and intellectual humility (understood as intellectual virtues), building off current proposals (...) in the literature, in an attempt to portray both in as broad and uncontroversial a manner as feasible. I then move to arguing how this prima facie incompatibility aligns with these understandings of faith and intellectual humility, and illustrate how this incompatibility is even clearer on one recent theory. I close by considering one avenue of response for those who want to maintain that, while conflicting in these ways, intellectual humility and faith can be simultaneously virtuous. (shrink)

Basic Formal Ontology was created in 2002 as an upper-level ontology to support the creation of consistent lower-level ontologies, initially in the subdomains of biomedical research, now also in other areas, including defense and security. BFO is currently undergoing revisions in preparation for the release of BFO version 2.0. We summarize some of the proposed revisions in what follows, focusing on BFO’s treatment of material entities, and specifically of the category object.

I argue that metaphysical views of material objects should be understood as 'packages', rather than individual claims, where the other parts of the package include how the theory addresses 'recalcitant data', and that when the packages meet certain general desiderata - which all of the currently competing views *can* meet - there is nothing in the world that could make one of the theories true as opposed to any of the others.

Mereological nihilism is the view that no objects have proper parts. Despite how counter‐intuitive it is, it is taken quite seriously, largely because it solves a number of puzzles in the metaphysics of material objects – or so its proponents claim. In this article, I show that for every puzzle that mereological nihilism solves, there is a similar puzzle that (a) it doesn’t solve, and (b) every other solution to the original puzzle does solve. Since the solutions to the (...) new puzzles apply just as well to the old puzzles, the old puzzles provide no motivation to be a mereological nihilist. (shrink)

I have both a smaller and a larger aim. The smaller aim is polemical. Kit Fine believes that a material thing—a Romanesque statue, for example, or an open door—can be distinguished from its constituent matter—a piece of alloy, say, or a hunk of plastic—without recourse to modal or temporal considerations. The statue is Romanesque; the piece of alloy is not Romanesque. The door is open; the hunk of plastic is not open. I argue that these considerations, when combined with (...) a proper understanding of how the use of ‘not’ is functioning, entail that the statue is the piece of alloy, and that the door is the hunk of plastic. Far from challenging the doctrine that a material thing is its matter, Fine’s observations confirm the view. My larger aim is methodological. I will show that natural language semantics can guide inquiry in certain areas of metaphysics by helping us to advance lingering debates. (shrink)

The chapter outlines an abstract theoretical framework that is currently (re-)emerging in the course of a theoretical convergence of several disciplines. In the first section, the fundamental problem of perception theory is formulated, namely, the generation, by the perceptual system, of meaningful categories from physicogeometric energy patterns. In the second section, it deals with basic intuitions and assumptions underlying what can be regarded as the current Standard Model of Perceptual Psychology and points out why this model is profoundly inadequate for (...) dealing with the fundamental problem of perception theory. In the third section, it discusses a level of analysis that promises to be fruitful for dealing, in conformity with established procedures of the natural sciences, with the problem of perceptual “meaning” and the problem of what constitutes a “perceptual object.” In the fourth section, it outlines a theoretical perspective on basic principles of the perceptual system which centers on the notions of complex data types and conceptual forms, and draws an entirely different theoretical picture of the role of the sensory input than traditional accounts. The final section focusses on the issue of material qualities and discusses, within the general theoretical framework outlined, some observations and results on the perception of certain material properties, namely, lustrous and glassy appearances.

Where Humeans rule out the possibility of material or non-logical necessity, and thus of any associated knowledge a priori, the German legal philosopher Adolf Reinach defends the existence of a wide class of material necessities falling within the domain of what can be known a priori, for example in fields such as color and shape, rational psychology, law and economics. Categories such as promise or claim or obligation are, in Reinach’s view, exist as nodes in a system of (...) necessary relations, so that anyone who has experience of relevant instances of these categories is implicitly aware also of a corresponding family of relations to certain other categories – as for example that every promise implies a mutually correlated claim and obligation. Midway between the two extremes of Hume and Reinach stands Searle, who accepts necessary relations of the mentioned sorts, but sees them as human creations, following from ‘constitutive rules’ analogous to the rules of chess. We seek to demonstrate that Searle does not occupy a stable and acceptable half-way house between Hume and Reinach; that he, too, if he is to do justice to the very constitutive rules which form the center of his approach, must on pain of circularity embrace something like the Reinachian position.

In Aristotle’s physics and biology, matter’s capacity for spontaneous, opaque, chance deviation is named by automaton and marked with a feminine sign, while at the same time these mysterious motions are articulated, rendered knowable and predictable via the figure of ta automata, the automatic puppets. This paper traces how automaton functions in the Aristotelian text as a symptomatic crossing-point, an uncanny and chiasmatic figure in which materiality and logos, phusis, and technē, death and life, masculine and feminine, are intertwined and (...) articulated. Automaton permits a mastery of generative materiality for teleological metaphysics, but also works to unsettle teleology’s systematic and unifying aspirations. (shrink)

Consider the distinctive qualitative property grass visually appears to have when it visually appears to be green. This property is an example of what I call sensuous color. Whereas early modern mechanists typically argue that bodies are not sensuously colored, Margaret Cavendish disagrees. In cases of veridical perception, she holds that grass is green in precisely the way it visually appears to be. In defense of her realist approach to sensuous colors, Cavendish argues that it is impossible to conceive of (...) colorless bodies, the very possibility of color experience requires that bodies are sensuously colored, and the attribution of sensuous colors to bodies provides the best explanation of color constancy. Although some passages might suggest that Cavendish endorses a reductive account of sensuous color, according to which sensuous color reduces to a body's microscopic surface texture, I argue that she accepts a nonreductive account, on which sensuous color is not thus reducible.

Material culture and technoculture not only provide openings to study culture, but raise questions about contemporary materialism and technology more generally as well. Material culture tells a story, though usually not the whole story. The meanings of things are various, and finding out what they are requires a variety of approaches, from simply asking people what their things mean or observing how they use or don’t use them, to backtracking their history, or contextualizing them in broader cultural context. (...) The transition from hunter-gatherer life to that of agriculturally-based civilization some twelve thousand or so years ago was a great watershed of consciousness, not only radically altering the relation to the living environment, but also producing the origins of materialism. One of civilization’s dubious distinctions was to introduce poverty as well as property and wealth. Consumption is clearly a driving force on the globe today, powering economies, promising identities, providing a cornucopia of commodities. Technoculture is at its center, both in material devices and in the ideas they communicate about how what one has affects what one is and can be. The problem of materialism is not whether to have materials for living, but in allowing them to become goals in themselves. (shrink)

Descartes and Boyle were the most influential proponents of strict mechanist accounts of the physical world, accounts which carried with them a distinction between primary and secondary (or sensible) qualities. For both, the distinction is a piece of natural philosophy. Nevertheless the distinction is quite differently articulated, and, especially, differently grounded in the two thinkers. For Descartes, reasoned reflection reveals to us that bodies must consist in mere extension and its modifications, and that sensible qualities as we conceive of them (...) based on sense perception can pertain only to the mind. Just how we are supposed to arrive at this realization is, this essay will argue, a deep puzzle that brings us to the basic assumptions of Descartes' metaphysics. For Boyle, by contrast, while reflection can reveal the unique explanatory status of mechanism, and, thus, the primary/secondary quality distinction, only experience can confirm its truth. Our central focus will be on Descartes, and on the question: How does he intend to remove the sensible qualities from the physical world, how does he strip them from bodies? I will try to show that Descartes has an argument that he takes to show a priori that sensible qualities cannot be attributed to the material world (as foundational qualities, or, as we conceive of them based on sense experience). The argument fails, however, leaving him with at best a partly empirical case for removing the sensible qualities, based on the purported explanatory success of his physics. (shrink)

This is an essay for undergraduates. I set out the statue/clay problem and Tibbles/Tib in rich detail. I also present, with less detail, some other puzzles about material composition.

Intensional evidence is any reason to accept a proposition that is not the truth values of the proposition accepted or, if it is a complex proposition, its propositional contents. Extensional evidence is non-intensional evidence. Someone can accept a complex proposition, but deny its logical consequences in two circumstances: (1) when her acceptance is based on intensional evidence, while the logical consequences of the proposition presuppose the acceptance of extensional evidence, e.g., she can refuse the logical consequence of a proposition she (...) accepts because she doesn’t know what the truth-values of its propositional contents; (2) when she accepts a proposition based on extensional evidence, but thinks that this evidence is insufficient to establish its logical consequences, which would require intensional evidence. It is argued that this tension is responsible for the counter-intuitive aspects of the material account of conditionals involving the negation of conditionals, hypothetical syllogism, contraposition and the inferential passage from disjunctions to conditionals (or-to-if). This tension is also behind some known puzzles involving conditionals, namely, conditional stand-offs, Adam pairs, the cheating partner example, jump-out conditionals, the problem of counterfactuals and the burglar’s puzzle. It is shown that this tension is always dissolved in favour of extensional evidence, since intensional evidence is defeasible, while extensional evidence is not. Thus, it is irrational to deny the logical consequences of an accepted proposition due to its reliance on intensional evidence and ignorance of its extensional evidence. (shrink)

There is an ongoing debate in the philosophical literature whether the conditionals that are central to deliberation are subjunctive or indicative conditionals and, if the latter, what semantics of the indicative conditional is compatible with the role that conditionals play in deliberation. We propose a possible-world semantics where conditionals of the form “if I take action a the outcome will be x” are interpreted as material conditionals. The proposed framework is illustrated with familiar examples and both qualitative and probabilistic (...) beliefs are considered. Issues such as common-cause cases and ‘Egan-style’ cases are discussed. (shrink)

The paper examines Posterior Analytics II 11, 94a20-36 and makes three points. (1) The confusing formula ‘given what things, is it necessary for this to be’ [τίνων ὄντων ἀνάγκη τοῦτ᾿ εἶναι] at a21-22 introduces material cause, not syllogistic necessity. (2) When biological material necessitation is the only causal factor, Aristotle is reluctant to formalize it in syllogistic terms, and this helps to explain why, in II 11, he turns to geometry in order to illustrate a kind of (...) class='Hi'>material cause that can be expressed as the middle term of an explanatory syllogism. (3) If geometrical proof is viewed as a complex construction built on simpler constructions, it can in effect be described as a case of purely material constitution. (shrink)

What are numbers, and where do they come from? A novel answer to these timeless questions is proposed by cognitive archaeologist Karenleigh A. Overmann, based on her groundbreaking study of material devices used for counting in the Ancient Near East—fingers, tallies, tokens, and numerical notations—as interpreted through the latest neuropsychological insights into human numeracy and literacy. The result, a unique synthesis of interdisciplinary data, outlines how number concepts would have been realized in a pristine original condition to develop into (...) one of the ancient world’s greatest mathematical traditions, a foundation for mathematical thinking today. In this view, numbers are abstract from their inception and materially bound at their most elaborated. The research updates historical work on Neolithic tokens and interpretations of Mesopotamian numbers, challenging several longstanding assumptions about numbers in the process. The insights generated are also applied to the role of materiality in human cognition more generally, including how concepts become distributed across and independent of the material forms used for their representation and manipulation; how societies comprised of average individuals use material structures to create elaborated systems of numeracy and literacy; and the differences between thinking through and thinking about materiality.

The purpose of this article is to support the logical incompatibility of the opposing views as a criterion for characterizing disagreements as genuinely metaphysical. That is, I intend to argue that a specific dispute is a metaphysical disagreement only when the conflicting views are governed by different logics. If correct, this criterion would not only help to separate merely verbal from genuine metaphysical debates, but it also would ground an argument against deflationism, guaranteeing the substantiality and relevance of metaphysics. (...) I intend to clarify the criterion, to present its basic foundations and commitments, to give some logical and metaphysical motivations for its adoption and some examples of its application.

The aim of this paper is to clarify the truth-functional interpretation of the logical connective of the material implication. The importance of such clarification lies in the fact that it allows avoiding the supposed paradoxes introduced by C. I. Lewis (1918). I argue that an adequate understanding of the history and purposes of logic is enough to dissolve them away. The defense is based on an exposition of propositional compositionalism. To compare, I also present Stalnaker’s (1968) alternative that seeks (...) to explain the implicit concept of conditionality of conditionals assertions. In order to reinforce my aim I expound the twelve different meanings of ‘implication’ stated by Corcoran (1993) in order to hold that a proper understanding of these meanings allows us to avoid ambiguities and confusions. Finally, I expect to show that despite the possible alternatives, compositionalism is still the best explanation for the truth-functionality account of logical connectives. (shrink)
