The philosophical investigations into universals was entangled with the combination of a certain Christian faith and Ontology, especially in ancient and medieval times. That is, God’s creative activity provided us with the ontological presumption which enabled universals to be predicated, be perceived and be thought about. Times then have changed, and “the modern turn” in Philosophy tends to resolve universals into concepts or linguistic phenomenon, which resulted that its certain Christian ontology no longer dominates the discourse on universals. On the (...) contrary to this philosophical tendency, modern theological discussions try to learn the development of philosophical investigations into universals, and to tackle the theological problems provoked by the modern natural science. Especially Karl Barth’s use of Universals-theory would obtain the assessment of “revolution in content” in the Church history, which, in previous studies, was yet entangled with the ambiguous word “…in motion…” and with the unclear argument “…understand true human nature from the nature of this one particular man Jesus Christ…” The present article will attempt to clarify this Barth’s practical use of Universals-theory by referring to philosophical arguments, then proving Barth’s intention and the difficulty of his complicated argument that Jesus Christ was one exemplar and in the same time was also the model, which is inconsistent with the basis of Universals-theory. It resulted that this Barth’s attempt will provide us with the possibility today of Universals-theory especially in the field of Religion. (shrink)

Strawson’s conception of analysis as a ‘connective linguistic analysis’ makes it possible for him to achieve an indefinitely large range of ideas or concepts among them are certain numbers of fundamental, general and pervasive concepts or concept-types which not only are pre-theoretical or ahistorical, but also together constitute a structural framework only within whichlogic, ontology and epistemology is possible. He takes it as a foundation for this conclusion that logic, ontology and epistemology are three aspects of one unified enquiry (or (...) trio)and strengthensit by this assertion thatwe can understand this unity through considering the fundamental operation of our language. In this paper, after tracing the line of development of Strawson’s philosophical idea of the trio and specifying the fundamental operation of our language (or the common thread which makes this unity possible), we stipulate that it is by means of ‘connective linguistic analysis’ that Strawsonwas able to unify epistemology, ontology and logic.

This paper aims at discussing the usage by Davidson as to events of Quine's criterion of ontological commitment. According to Davidson, we are ontologically committed to the existence of events as individuals as we employ literally terms such as ‘Caesar’s death’, for instance. David-son extends this analysis to actions as well, since actions are human events. One of the consequences of this view is that psychology deals with individual events in a non-lawful way. An alternative view is here proposed, based (...) on a complementary criterion, namely ontological den-sity, according to which from the point of view of a given theory, we can always distinguish between events (or phenomena) and individuals (entities) among the overall occurrences described by the theory. Some consequences of this alternative view of psychology as a science dealing lawfully with general human events are also explored here. (shrink)

I am populating this file from the bottom up. Later years are still empty. Try stuff in or before 1998 for a start. My Oxford DPhil Thesis (1962) is the oldest item available here.

As a step towards comprehensive computer models of communication, and effective human machine dialogue, some of the relationships between communication and affect are explored. An outline theory is presented of the architecture that makes various kinds of affective states possible, or even inevitable, in intelligent agents, along with some of the implications of this theory for various communicative processes. The model implies that human beings typically have many different, hierarchically organized, dispositions capable of interacting with new information to produce affective (...) states, distract attention, interrupt ongoing actions, and so on. High "insistence" of motives is defined in relation to a tendency to penetrate an attention filter mechanism, which seems to account for the partial loss of control involved in emotions. One conclusion is that emulating human communicative abilities will not be achieved easily. Another is that it will be even more difficult to design and build computing systems that reliably achieve interesting communicative goals. (shrink)

A longstanding philosophical tradition holds that the primary objects of hearing are sounds rather than sound sources. In this case, we hear sound sources by—or in virtue of—hearing their sounds. This paper argues that, on the contrary, we have good reason to believe that the primary objects of hearing are sound sources, and that the relationship between a sound and its source is much like the relationship between a color and its bearer. Just as we see objects in seeing their (...) colors, so we hear sound sources in hearing their sounds. (shrink)

I recently discovered that work I was doing in the laboratory and in theoretical writings was implicitly taking a position on a set of questions that philosophers had been worrying about for much of the past 30 or more years. My clandestine involvement in philosophical issues began when a computer science colleague and I were trying to build a model of geometrical reasoning that would draw a diagram and notice things in the diagram as it drew it (Pylyshyn, Elcock, Marmor, (...) & Sander, 1978). One problem we found we had to face was that if the system discovered a right angle it had no way to tell whether this was the intersection of certain lines it had drawn earlier while constructing a certain figure, and if so which particular lines they were. Moreover, the model had no way of telling whether this particular right angle was identical to some bit of drawing it had earlier encountered and represented as, say, the base of a particular triangle. There was, in other words, no way to determined the identity of an element (I use the term “element” when referring to a graphical unit such as used in experiments. Otherwise when speaking informally I use the term “thing” on the grounds that nobody would mistake that term for a technical theoretical construct. Eventually I end up calling them “Visual Objects” to conform to usage in psychology) at two different times if it was represented differently at those times. This led to some speculation about the need for what we called a “finger” that could be placed at a particular element of interest and that could be used to identify it as particular token thing (the way you might identify a particular feature on paper by labeling it). In general we needed something like a finger that would stay attached to a particular element and could be used to maintain a correspondence between the individual element that was just noticed now and one that had been represented in some fashion at an earlier time. The idea of such fingers (which.... (shrink)

Summary of Anna Pilatova’s doctoral thesis A User’s Guide to Proper Names, Their Semantics And Pragmatics The origins of this work go all the way back to my reading of Kripke’s Naming and Necessity in 1993. It had left me with a feeling of dissatisfaction that lingered long enough to inspire my MA thesis (on Internalism and Externalism in the Theories of Reference), and finally inspired the current work. Over time, I became acquainted with other influential accounts of reference of (...) proper names, but my unease with essentialism and wariness of direct designation remained. In the User’s Guide to Proper Names, I seized the opportunity to analyse what I thought was problematic with the mainstream theories of reference of proper names. I tried to tease apart a number of related doctrines about the behaviour of proper names, and thus arrive at a better understanding of how the various parts of the theories of reference I chose to analyse are related. This helped me to develop my own proposal regarding both the semantics and the pragmatics of proper names. The Guide is organised around a particular approach to the tasks of a semantic theory. According to this view, proposed by Stalnaker, a semantic theory dealing with proper names should account for the descriptive semantics of names, their foundational semantics, and the semantics of modal statements in which they figure. Descriptive semantics focuses on the contribution a proper name makes to the truth-value of sentences in which it occurs. Based on such an analysis, a proper name is assigned a semantic value, which is supposed to provide us with an interpretation of that name. A crucial part of this task is to see just what kind of thing the semantic value of a proper name is. In interpreting sentences containing proper names, one can, and often does, use the notion of possible worlds. This is especially true if the sentences in question are modal. There are various approaches to modality, which carry with them different sets of presuppositions. An analysis of the systematic features and presuppositions of various possible-world frameworks is a part of the task of the semantics of modal statements. Another task of semantics of modal statements is to investigate whence the constraints on possible worlds used in analysing these statements should derive, that is, whether, and to what degree, they should derive from the descriptive or the foundational part of the semantic enterprise. Both of these parts of a semantic theory have the potential to make predictions about the foundational semantics of proper names, which deals with the speaker’s behaviour and communication. Foundational semantics aims at answering the following question: What makes it the case that the language spoken by a particular individual or community has the very descriptive semantics it has? In this investigation, one looks at the speaker, her intentions and communicative goals, and tries to look at the strategies she uses to get her (linguistic) point across. To show the usefulness of organising the User’s Guide to Proper Names around these distinctions, and to provide their proper characterisation, is the task of the first part of the introductory first chapter, Outlining the Field and Introducing Some of the Players. In the second part of the same chapter, Setting the Scene, I give a preliminary outline of some of the notions needed to describe the theories of reference that are later investigated, that is mainly the theories proposed by Kripke, Kaplan, Lewis, and Stalnaker. The second chapter, Descriptive Semantics, focuses on the descriptive semantics proposed by Kripke and Kaplan for proper names. In the first part of the chapter, I introduce several arguments in favour of rigid designation. A closer look reveals that none of the three arguments in question -- the modal, the epistemological, and the semantic one -- is actually an argument for rigid designation. They all just argue against some forms of descriptivism. Moreover, in the case of the modal and the epistemological argument, it is relatively easy to find forms of descriptivism that are immune to the lines of reasoning proposed in these arguments. The semantic argument seems to be the strongest of the three. An analysis of a direct argument for rigid designation highlights the connection between rigid designation and certain preconceptions about the identity of individuals. A further investigation of the notion of identity of individuals across possible worlds emerges at this point as an important issue to tackle. It also becomes clear that rigid designation alone cannot fully determine the Kripkean picture of names as non-descriptive entities referring without a mediation of any sort of conceptual content. In the second part of Chapter 2, I introduce the basic notions of Kaplan’s approach to the descriptive semantics of proper names. It turns out that in order to derive the familiar Kripkean picture of proper names, one has to presuppose direct reference for names and at least some version of haecceitism for the individuals in question. While, as we show, Kaplan’s framework does not work well for proper names, it gives us conceptual tools that help us in our undertaking. In the third chapter, Modal Statements, Individuals, and Essences, I analyse three different approaches to building a possible-world framework, Lewis’s, Kripke’s, and Stalnaker’s. In each case, the same questions are asked: What is the motivation and intended field of application of this framework? What are the ontological commitments of the approach? What form of essentialism, if any, does it imply? How does it deal with the notion of an individual? In Lewis’s case, the main problem turns out to be the theory of counterparts, which is, as I show, an integral part of his approach. The concept of an individual implied by it does not seem to correspond to any intuitive reading of counterfactual statements involving individuals. The investigation of Kripke’s framework focuses on describing the weakest form of essentialism that has to be presupposed to make the proposal work. Once that is concluded, I analyse the essentialism Kripke actually proposes, and the motivation and presuppositions on which it rests. I conclude that its motivation cannot be said to come from an analysis of language and that it presupposes a particular form of scientific realism. The rest of the chapter is devoted to a reconstruction and analysis of Stalnaker’s possible world framework, which turns out to be rather more cautious about metaphysical presuppositions and more suited for an analysis of natural language. As in the two previous proposals, I try to reconstruct the notion of actual world that is presupposed here. In the fourth chapter, Foundational Semantics, I investigate the notion of proposition implied by Lewis’s, Kripke’s, and Stalnaker’s approach. I focus on propositions containing proper names, and analyse the way in which each of the conceptions mentioned above is vulnerable to the problem of logical omniscience. An analysis of Lewis’s framework reveals that the concept of proposition implied by it is so weak as to be rather uninteresting. An investigation of Kripke’s concept of proposition deals not only with the systematic issues, but also with the Pierre puzzle and various attempts at solving it. I present a number of different approaches to the problem and compare their merits. Stalnaker is very worried about the problem of logical omniscience, and yet it turns out that his conception is less vulnerable to the adverse consequences of the problem of logical omniscience than other frameworks we investigate. I point out that various pragmatic features of Stalnaker’s framework (the epistemic nature of his possible-world framework, the Gricean principles built into the notion of assertion) help to counterbalance and mitigate the scope of the problem of logical omniscience within it. In Chapter 5, User-friendly Descriptive Semantics, I present and motivate my own proposal for the descriptive semantics of proper names and the treatment of modal statements in which they figure. Basically, the aim is to preserve the notion of names as rigidly designating expressions while admitting as little metaphysics as possible. Working with epistemic possible worlds whose domain is in each case co-determined by a particular context enables me to develop a very intuitive plausible notion of individual, to which a name can be said to refer rigidly. The interpretation of modal statements is then driven not by essentialist constraints in the common sense of the term, but by context-derived limitations, which seems to be a more natural approach. In the sixth and last chapter, Names, Indexicality, and Ambiguity, I develop a view of foundational semantics inspired by the pragmatic observation that in common parlance one can say that a name, `John Smith’ for instance, can refer to numerous individuals. A lot of attention is given to the ontology of names, and the question `What is a name?’ delivers answers which are then used in a discussion about whether names should be seen as indexical or ambiguous. I adopt the ambiguity view, and propose a way of using a Stalnakerian possible-world framework to derive intuitively plausible results for some difficult cases. The weight of the discussion all through the guide rests in an examination of different kinds of presuppositions implied by various possible-world frameworks and the notion of the individual used in accounts of the behaviour of proper names. In my own account of these issues, I do without any metaphysical assumptions and aim at describing communication in terms accessible to its participants. (shrink)

There is a well-known line of thought, associated with Donald Davidson, that connects the notion of a perceptual given—of non-linguistic or non-conceptual experience of the world—with skepticism. Against this, I argue that the notion of what is given in perception leads to skepticism only on certain interpretations. I argue, in fact, that there must be perceptual experience such that there is “something it is like” to have it, or that would provide the subject of a phenomenological analysis, if we are (...) to block skepticism in its most radical forms. In particular, I claim that there is a distinctive phenomenology of the experience of agency. These phenomenological claims are conclusions of a transcendental argument according to which our having such experience is a condition of our having a meaningful language. Moreover, the same transcendental argument is sufficient to show the incoherence of radical skepticism about the external world. And I argue that the proper understanding of perceptual experience—as object involving—renders the standard objections to transcendental arguments ineffective. (shrink)

The main idea of this book is that perceiving is a way of acting. Perception is not something that happens to us, or in us. It is something we do. Think of a blind person tap-tapping his or her way around a cluttered space, perceiving that space by touch, not all at once, but through time, by skillful probing and movement. This is, or at least ought to be, our paradigm of what perceiving is. The world makes itself available to (...) the perceiver through physical movement and interaction. In this book I argue that all perception is touch-like in this way: perceptual experience acquires content thanks to our possession of bodily skills. What we perceive is determined by what we do ; it is determined by what we are ready to do. In ways I try to make precise, we enact our perceptual experience; we act it out. (shrink)

The material is organized in four sections: (i) the nature of events, with emphasis on the opposition between events as particulars and events as universals; (ii) identity and indeterminacy, with emphasis on the unifier/multiplier controversy; (iii) events and logical form, with emphasis on Davidson’s treatment of the form of action sentences; (iv) linguistic applications, with emphasis on issues concerning aspectual phenomena, the (...) telicity/atelicity distinction, the treatment of statives, and temporal quantification.

Over the past 50 years, there has been a great deal of philosophical interest in laws of nature, perhaps because of the essential role that laws play in the formulation of, and proposed solutions to, a number of perennial philosophical problems. For example, many have thought that a satisfactory account of laws could be used to resolve thorny issues concerning explanation, causation, free-will, probability, and counterfactual truth. Moreover, interest in laws of nature is not constrained to metaphysics or philosophy of (...) science; claims about laws play essential roles in areas as diverse as the philosophy of religion (e.g., in the argument from design) and the philosophy of mind (e.g., in the formulation of Davidson’s anomalous monism). In my dissertation, I consider and reject the widely-held thesis that the facts concerning laws can be reduced to the facts concerning the particular entities that the laws “govern,” and that the laws thus have no independent existence. I instead defend a version of nomic primitivism, according to which the facts about laws cannot be reduced to facts that are themselves non-nomic – i.e., to facts that do not fundamentally involve laws, counterfactuals, causes, etc. Insofar as the truth or falsity of reductionism about laws has implications for many of the problems mentioned above, I think that this result should be of interest even to those who who do not work in metaphysics or the philosophy of science. My methodology, which I lay out and defend in Chapter One, is a version of Carnapian explication. This method emphasizes the importance of articulating and maintaining clear distinctions between (1) the vague concept (or concepts) law of nature inherent in ordinary language and scientific practice and (2) the precise analyses of “law of nature” that philosophers have proposed as potential replacements for this concept. I argue that metaphysics-as-explication has clear advantages over rival conceptions of metaphysical methodology; in particular, it allows us to formulate evaluative criteria for metaphysical claims. In Chapter Two, I offer an example of how careful attention to concepts already in use can help resolve philosophical debate. Specifically, I argue that much recent literature has mistakenly assumed that there is only one concept of “law of nature” in use, while there are in fact at least two. Strong laws are the principles pursued by fundamental physics: they are true, objective, and bear distinctive relationships to counterfactuals and explanation. Weak laws, by contrast, lack at least one of these distinctive characteristics but play central roles in both the “special sciences” and in everyday life. In Chapters Three and Four, I offer extended arguments against the two most prominent versions of reductionism about laws – Humeanism and law necessitarianism. According to philosophical Humeans, the laws of nature supervene upon the non-modal, non-nomic facts concerning the behavior of particular things at particular times and places. Law necessitarians, by contrast, argue that the laws are in fact metaphysically necessary, and that which laws there are is determined by a class of primitive, modally loaded facts concerning the essences, natures, or dispositions. I argue that both of these views are mistaken insofar as they disagree with well-entrenched scientific practices and those in favor of reductionism have failed to provided sufficient reason for thinking that these practices should be revised. Much of my argument is focused on the role played by a number of supposed methodological principles, including appeals to intuition, parsimony, and methodological naturalism. While the conclusions of this dissertation are explicitly constrained to laws, many of the arguments should be of interest to those who are concerned about philosophical methodology (especially in the role of intuition in philosophical argument) or the appropriate relation between metaphysics, science, and the philosophy of science.

Donald Davidson and John Searle famously differ, among other things, on the issue of animal thoughts. Davidson seems to be a latter-day Cartesian, denying any propositional thought to subhuman animals, while Searle seems to follow Hume in claiming that if we have thoughts, then animals do, too. Davidson’s argument centers on the idea that language is necessary for thought, which Searle rejects. The paper argues two things. Firstly, Searle eventually argues that much of a more complex thought does depend on (...) language, which reduces a distance between himself and Davidson. Secondly, some of Davidson’s suggestions are promising – in particular the idea that we may lack a vocabulary to capture the contents of animal thoughts. Based on this insight, one might, pace Davidson, grant thoughts to animals. However, this does not mean, pace Searle, that it should be possible to construe even the simplest of such thoughts as propositional. Perhaps we need to move beyond Davidson and Searle by developing a theory of nonpropositional thought for animals. (shrink)

The longstanding species problem in biology has a history that suggests a solution, and that history is not the received history found in many texts written by biologists or philosophers. The notion of species as the division into subordinate groups of any generic predicate was the staple of logic from Aristotle through the middle ages until quite recently. However, the biological species concept during the same period was at first subtly and then overtly different. Unlike the logic sense, which relied (...) on definitions of the essence of both genus and species, biological species from the time of Epicurus were consistently considered to involve a reproductive element: in short, living species relied not on essential definitions, but on the generative cause, which might not be definable. I term this the generative conception of species: species were the generation by reproduction of form. This undercuts the claim that species before Darwin were essentialist, and divorces the notion of a type from that of essence. In fact, as late as the end of the nineteenth century, logicians explicitly treated biological “species” as a homonym only of logical essentialist species, and permitted considerable deviation from the type or form. At every point, species in logic were thought to be a subset, in effect, of some more general notion. I sketch a history of both philosophical and biological traditions of the species concept, before turning to the current conceptions. These are reconsidered in the light of this history, and in particular Mayr’s changing views are shown to be somewhat Whiggish, historiographically. Of the many touted biological species concepts, only one of which (Mayr’s) is called _the_ Biological Species Concept, none appears to capture all the relevant facts, intuitions, and operational requirements of biology. Cladistic conceptions, however, have much in common with the older philosophical literature, in that the natural group of cladism is the clade, or monophyletic group. After considering the Individuality Thesis, and the metaphysics of species, we see that species are the most particular terminal taxa in a clade, and that they are “defined” in terms of the particular synapomorphies, or evolved characters, that are causally responsible for keeping the lineages that organisms form distinct from one another. In this way, we can remain within the generative conception of species that has been in play for over two millennia, and yet avoid the pitfalls of prior attempts to find a universal conception of species.

Extended critical discussion of Lucy Allais, *Manifest Reality*.

The article discusses the problem of whether the self, or the subject, is real. There are several realist and anti-realist solutions to this problem. The author interprets all possible positions concerning this issue as conceptions of a certain relationship between the phenomenal self and the ontological self. In line with what is called phenomenal, or experiential minimalism, the author concludes that the experiential dimension of the self is sufficient for it to be real without qualification. Providing an argument against anti-realism, (...) the author differentiates between strong and reductive realism and maintain that selves criticized by anti-realists like Metzinger are things of strong realism, while in fact selves might turn out to be the things of reductive realism. The author suggests a solution to another problem of the ontology of the self, namely the problem of characterization. By endorsing minimalism, the self is characterized as the experiential faculty. According to the suggested version of minimalism, having experience is a necessary and sufficient condition to be a self or a subject. All other properties ascribed to subjects in philosophical literature are contingent. Properties like these are of course attributes of subjects, but they are neither necessary nor sufficient for subjectivity. A subject who loses these properties does not cease to be a subject. On the contrary, a thing which has lost its experiential ability ceases to be a subject. In addition, there are non-human subjects who may lack all subjectivity-related features, except for the experiential faculty, and still be considered subjects. Phenomenal minimalism is a solution to the problem of the reality of selves. Subjects, or selves, are real as things with the experiential faculty. Finally, the author rejects pluralism and conventionalism. Instead, essentialist realism is endorsed. (shrink)

I review Michael T. Ferejohn's "Formal Causes: Definition, Explanation, and Primacy in Socratic and Aristotelian Thought".

G. F. Stout is famous as an early twentieth century proselyte for abstract particulars, or tropes as they are now often called. He advanced his version of trope theory to avoid the excesses of nominalism on the one hand and realism on the other. But his arguments for tropes have been widely misconceived as metaphysical, e.g. by Armstrong. In this paper, I argue that Stout’s fundamental arguments for tropes were ideological and epistemological rather than metaphysical. He moulded his scheme to (...) fit what is actually given to us in perception, arguing that our epistemic practices would break down in an environment where only universals were given to us.

My starting point is that discussions in philosophy about the ontology of technical artifacts ought to be informed by classificatory practices in engineering. Hence, the heuristic value of the natural-artificial distinction in engineering counts against arguments which favour abandoning the distinction in metaphysics. In this chapter, I present the philosophical equipment needed to analyse classificatory practices and then present a case study of engineering practice using these theoretical tools. More in particular, I make use of the Collectivist Account of Technical (...) Artifacts (CAT) according to which there are different classificatory practices for natural, artificial, and social objects. I demonstrate that in the community studied, artificial kinds are marked by distinctive classificatory practices. The presence of these distinctive classificatory practices in engineering with regard to artificial kinds should inform discussions about the ontology of technical artifacts just as the distinctive classificatory practices in natural science inform discussions about natural kinds.

Cooperation admits of degrees. When factory workers stage a slowdown, they do not cease to cooperate with management in the production of goods altogether, but they are not fully cooperative either. Full cooperation implies that participants in a joint action are committed to rendering appropriate contributions as needed toward their joint end so as to bring it about, consistently with the type of action and the generally agreed upon constraints within which they work, as efficiently as they can, where their (...) contributions are sensitive to information (where available) about how others are contributing in the sense that they adjust as needed their contributions in light of information about how others are contributing to ensure effective pursuit of their joint end, where this includes rendering aid to other participants if needed, insofar as they are able. Full cooperation entails those cooperating are engaged in a joint intentional action. Some prominent studies of joint intentional action focus exclusively on cases of full cooperation (notably that of Michael Bratman (2014)). But not all joint intentional action is fully cooperative. One example is the work slowdown. Another example is provided by competitive games like chess and football, or sports like boxing and wrestling, where participants are clearly not intending to contribute to the pursuit of all of the goals of the others engaged in the activity, even when those goals are internal to the type of activity in question, but instead intend actively to frustrate some of them. In this paper, I provide a taxonomy of forms of non-cooperative behavior within the context of behavior that is still to some degree cooperative, and I argue that the minimal conditions of joint intentional action define minimal cooperative behavior, that is, that minimally joint intentional action is per se minimally cooperative behavior. I define in precise terms what that comes to, and how it is possible in cases in which it seems that one or more participants are in one or more ways acting so as to frustrate the contributions of other participants to their joint action.

I develop an interdisciplinary framework for understanding the nature of agents and agency that is compatible with recent developments in the metaphysics of science and that also does justice to the mechanistic and normative characteristics of agents and agency as they are understood in moral philosophy, social psychology, neuroscience, robotics, and economics. The framework I develop is internal perspectivalist. That is to say, it counts agents as real in a perspective-dependent way, but not in a way that depends on an (...) external perspective. Whether or not something counts as an agent depends on whether it is able to have a certain kind of perspective. My approach differs from many others by treating possession of a perspective as more basic than the possession of agency, representational content/vehicles, cognition, intentions, goals, concepts, or mental or psychological states; these latter capabilities require the former, not the other way around. I explain what it means for a system to be able to have a perspective at all, beginning with simple cases in biology, and show how self-contained normative perspectives about proper function and control can emerge from mechanisms with relatively simple dynamics. I then describe how increasingly complex control architectures can become organized that allow for more complex perspectives that approach agency. Next, I provide my own account of the kind of perspective that is necessary for agency itself, the goal being to provide a reference against which other accounts can be compared. Finally, I introduce a crucial distinction that is necessary for understanding human agency: that between inclinational and committal agency, and venture a hypothesis about how the normative perspective underlying committal agency might be mechanistically realized.

The theory of events as property-instances has been considered one of the most widely accepted metaphysical theories of events. On the other hand, several philosophers claim that if both events and objects perdure, then objects must be identified with events. In this work, I investigate whether these two views can be held together. I shall argue that if they can, it depends on the particular theory of instantiation one is to adopt. In particular, I shall conclude that the theory of (...) events as property-instances and the view that identifies objects with events can be held together only if instances of eventive universals are temporal parts of objects – namely, those temporal parts that have the universals in question.

It is commonly held that Bradley’s regress has a solution within a trope ontology. This seems to happen when a bundle is understood as constituted by non-transferable tropes. It also seems to happen when a bundle is understood as constituted by transferable tropes related by a relational trope of compresence whose existence specifically depends on those relata. In this article I demonstrate that these proposals fail in addressing the essential question that underlies the regress, incurring in a question-begging response already (...) anticipated by Bradley.

Last year at VSS, Bullot, Droulez & Pylyshyn reported studies using a Modified Traveling Salesman Paradigm in which a virtual vehicle had to visit up to 10 targets once and only once, and in which the invisible targets were identified only by line segments pointing from the vehicle toward each target. We hypothesized that subjects used two distinct strategies: A “location-based strategy”, which kept track of where targets were located in screen coordinates, and a “segment-based strategy” that kept track of (...) which segments corresponded to visited targets. We report new studies that further explore these two strategies. Subjects passively observed a computer-controlled virtual vehicle that visited a number of targets. Two forms of display were used: an “Allocentric” display, in which the vehicle moved and the targets remained fixed in screen coordinates, and an “Egocentric” display, in which the vehicle's position on the screen remained fixed while the targets moved -- as if the environment were being viewed by an observer on the vehicle. At the end of each trial, the directional segments were extended to the edge of the screen and subjects were asked to perform two tasks by referring to these segments. In the “status task” observers had to indicate for each segment whether the corresponding target had been visited or not. In the “locating task” they had to locate each target along its directional segment. Performance on these two tasks measures the use of the two hypothesized strategies. Results showed that observers do well on the status task with 4 or 6 targets in both display conditions, but do poorly on the locating task, especially in the egocentric condition when there are more targets. These results are consistent with the hypothesis that in the egocentric condition the MTSP task is carried out primarily by segment-tracking, which can be viewed as a deictic strategy. (shrink)

It is notoriously difficult to define Metaphysics1, its content, its method, its language, its scope. Thus I will not even try an attempt here. I will rest content to point out some widely held characterizations. A long and highly influential tradition maintains that Metaphysics is the study of being qua being. It is concerned with what there is, what kind of things are the things that there are, what properties do they have, how they are related. In this sense Metaphysics (...) deals with the more general features of reality, the most fundamental categories of being. Call this tradition General Metaphysics. (shrink)

In my thesis I argue for a philosophical-anthropological approach which enables investigations in empathy and care by opening up a window on the motivation of recognition. I show how biographies as narratives can help to understand the other within her or his own life-world, even if the life-world is the very part of our personality as a dividually conceived relational self. Therewith, personhood can be conceived in a new concept of personhood that is understood as a category of the human (...) being endowed with a stronger focus on culturally and historically founded dividuality and relationality, instead of relying exclusively on individuality and subjectivity. To show this relational movement in our life-world, I introduce ‘the Melanesian’ worldview on personhood. This worldview assumes that we are holistically relational. Thus, it lets the perception of an objective world shift into a world of animated entities which become parts of the human. Other people are also part of our life, and, in this way, take part in the life-world − and thus in life. In consequence, the life-world as the place where humans get in touch with each other builds up the social community: others have a particular role just as we take part in their lives. Our relationship with others is related to certain tasks in the social community and to definitions of personality and character. In academia, it is common ground that increasing individuality causes an increasing claim to recognition, especially since Honneth’s revival and actualization of Hegel’s concept of recognition. It is also Honneth who is inseparably linked with the recent philosophical discussion about recognition. We are recognized and we recognize others both on a personal as well as on a social level. The leading question, still unsolved and at the same time unsolvably linked with the relationship of individual and society, is: why are we relying on recognition? In other words: how do we recognize me, my self, and the other? My approach of a self-based model of mutual recognition follows two methodological paradigms: hermeneutics and phenomenology. Unsurprisingly, the hermeneutical investigation of our self in relation to mutual recognition has to start at the current state of the recognition debate, and takes its way to the anthropological state of personhood- and self-debate. The phenomenological approach constitutes the second main basis for an approach to a self-based concept of mutual recognition. Also the connection of philosophical and anthropological approaches to identity, personhood, and self-recognition is very fruitful in the way of developing a holistic approach of mutual recognition. To support this, I connect Western approaches in the phenomenological and hermeneutical traditions as well as theories of narrativity and human biography with non-Western approaches to elaborate and emphasize the intersection of both approaches. In consequence, the Cartesian Ego is rejected in favour of a decentral, cosmomorphic, and sociocentric approach to personhood. This anthropological approach is merged with a narrative concept of identity to emphasize the self-reflexive way of personal identity. Building on this set of philosophical and anthropological arguments, my purpose is to draw up a self-based model of mutual recognition which includes all stages of mutual recognition: recognition of one’s own identity, recognition of one’s own acting, recognition of others, and evaluative recognition. I begin this journey with preliminary remarks on recognition, person, and self by elaborating the state of the art in approaches to mutual recognition, the Anthropological notion of personhood, individual, and self, and their Philosophical notion. In the second part of my work, I show how these approaches compose a self-based model of mutual recognition. Here we receive the idea how we are recognized: through empathic understanding an act of knowledge is performed, in which the other is perceived and acknowledged as another human similar to ourselves. Therefore, empathic understanding, feelings of sympathy, care and solicitude, personal ethos, and theories of mind are related to mutual recognition. The definition of our being through empathy highlights our social wellbeing. By implication we refer to the recognition of others as constitutive of the community, since we recognize others and take care of them. (shrink)

The question I intend to answer is whether one can speak of a tacit metaphysics, not expressed conceptually, but nevertheless common. If the answer is positive and providing that it is specific to day-to-day life, such metaphysics may be called everyday metaphysics. To this end, I review the meaning of everyday life and its ambivalent character. Next, I present several milestones in the debate on the subject, from authors who have focused on a kind of usual, common or ‘natural’ metaphysics. (...) Lastly, I formulate the idea under consideration, namely that everyday life implies or underlies a certain metaphysics. I note that it is an implicit metaphysics – not expressed formally – and rather free. Embraced in experience with a certain degree of freedom, it is recognisable by means of certain representations active in our mind, by the manner of speaking or of understanding and by the common forms of expression. Its vibrancy, concrete and relaxed character makes it highly evocative of the mental life of an era. It ensures a truly essential difference in our everyday mode of being. (shrink)

Kant is often considered to have argued that perceptual awareness of objects in one's environment depends on the subject's possession of conceptual capacities. This conceptualist interpretation raises an immediate problem concerning the nature of perceptual awareness in non-rational, non-concept using animals. In this paper I argue that Kant’s claims concerning animal representation and consciousness do not foreclose the possibility of attributing to animals the capacity for objective perceptual consciousness, and that a non-conceptualist interpretation of Kant’s position concerning perceptual awareness can (...) actively endorse this attribution. Kant can consistently allow that animals have a point of view on the objective world which possesses a distinctive phenomenal character while denying what seems most important to him – viz. that animals have the capacity to take cognitive attitudes towards, and thus self-ascribe, their own representational states.

My aim is to show that once we appreciate how Searle (1958) fills in the details of his account of proper names – which I will dub the presuppositional view – and how we might supplement it further, we are in for a twofold discovery. First, Searle’s account is crucially unlike the so-called cluster-of-descriptions view, which many philosophers take Searle to have held. Second, the presuppositional view he did hold is interesting, plausible, and worthy of serious reconsideration. The idea that (...) Searle’s account is a largely Fregean interlude between the Fregean description theory of proper names and Kripke’s proposals presented in “Naming and Necessity” is in major ways a myth, a mythical chapter in how the story of 20th-century philosophy of language is often told.

The thesis of this paper is that – in order to avoid trivializations – a Philosophy of Birth needs to elaborate a precise concept of transformation and distinguish it carefully from that of adaptation. While transformation goes beyond the limited self-referential perspective of an individual and, on the social level, of the gregarious identity, adaptation aims at strengthening or preserving the old self-referential equilibrium. Transformation is driven by what Zambrano has called, with an exceptionally happy expression, the “hunger to be (...) born completely”. Such a hunger pushes one to continue one’s own birth through the encounter with the Other. Transformation has a creative feature that is made possible by two factors: the surplus of the effect over the cause, and the priority of the real over the possible. These premises lead to a radical questioning of the primacy of the possible on the real, at least as it has been conceived so far in mainstream Western philosophy, with few exceptions, such as Schelling, Bergson and Scheler. In the first part of this text, I shall consider a new Philosophy of Birth in the light of the concept of transformation and in this regard deal with several core themes such as the hunger to be born completely, the new beginning, creative time, the priority of the real over the possible, the limits of finalism, the surplus of effect over cause, and the creative force that expresses itself in the act of ideation. In the second part, I shall analyze the relation between birth and death and focus especially on their intimate and reciprocal connection by referring to the image of the seed that, after falling on the ground, germinates and breaks its own integument.

Three influential forms of realism are distinguished and interrelated: realism about the external world, construed as a metaphysical doctrine; scientific realism about non-observable entities postulated in science; and semantic realism as defined by Dummett. Metaphysical realism about everyday physical objects is contrasted with idealism and phenomenalism, and several potent arguments against these latter views are reviewed. -/- Three forms of scientific realism are then distinguished: (i) scientific theories and their existence postulates should be taken literally; (ii) the existence of unobservable (...) entities posited by our most successful scientific theories is justified scientifically; and (iii) our best current scientific theories are at least approximately true. It is argued that only some form of scientific realism can make proper sense of certain episodes in the history of science. -/- Finally, Dummett’s influential formulation of semantic issues about realism considered. Dummett argued that in some cases, the fundamental issue is not about the existence of entities, but rather about whether statements of some specified class (such as mathematics) have an objective truth value, independently of our means of knowing it. Dummett famously argued against such semantic realism and in favor of anti-realism. The relation of semantic realism to the metaphysical construal of realism and Dummett’s main argument against semantic realism is examined. (shrink)

Ontology as a branch of philosophy is the science of what is, of the kinds and structures of objects, properties, events, processes and relations in every area of reality. ‘Ontology’ is often used by philosophers as a synonym for ‘metaphysics’ (literally: ‘what comes after the Physics’), a term which was used by early students of Aristotle to refer to what Aristotle himself called ‘first philosophy’. The term ‘ontology’ (or ontologia) was itself coined in 1613, independently, by two philosophers, Rudolf Göckel (...) (Goclenius), in his Lexicon philosophicum and Jacob Lorhard (Lorhardus), in his Theatrum philosophicum. The first occurrence in English recorded by the OED appears in Bailey’s dictionary of 1721, which defines ontology as ‘an Account of being in the Abstract’. (shrink)

In this paper Animalism is analysed. It will be argued that Animalism is correct in claiming (i) that being of a certain sort of animal S is a fundamental individuative substance sortal concept (animal of the species Homo Sapiens), (ii) that this implies that Animalism is correct in claiming that persons such as us are, by necessity, human beings, (iii) that remaining the same animal is a necessary condition for our identity over time. Contrary to Animalism it will be argued (...) that this does not imply that person should be understood as a phased sortal concept. It will be argued that Animalism rests upon a prior conception of person, and that this implies that person must be understood as a basic substance sortal concept through which we have to individuate ourselves and others. It is further argued that this, together with the insights of Animalism, implies that persons, by necessity, are beings of a biological nature. (shrink)

Grenon and Smith (2004) propose a framework for the ontology of things in space and time involving and invoking the distinction between continuants and occurrents, which has become a key element of Basic Formal Ontology (BFO). The terminology of SNAP (from “snapshot:” state of a continuant at a time) and SPAN (how an occurrent develops over an interval or timespan) occurs in that paper’s title. While any commonsense ontology will have a place for both continuants and occurrents, there is much (...) room for philosophical debate on whether one of them is more basic than the other, or can be reduced to the other, or whether they are equally fundamental, or whether they are two different perspectives on the same reality. Grenon and Smith opt for the last of these. They call the accounts of continuants (SNAP) and occurrents (SPAN) both “ontologies.” They do not have a single ontology of all that is in space and time. This dialog throws a few of the common arguments around a bit and comes to no sure conclusion. But one of the characters bears a faint resemblance to a certain Buffalonian philosopher. (shrink)

This article defends strong formal ontological conception of ontological categories against Lewis's "deflanationary" conception. Here, it sides with E.J. Lowe (1998) among others. However, the paper argues against Lowe's conception of metaphysics as an a priori science. Different category systems are compared and the best system is selected on the basis of its ability to accommodate our the best a posteriori conceptions of reality.

Theory and Reality is about the connection between true theories and the world. A mathematical framefork for such connections is given, and it is shown how that framework can be used to infer facts about the structure of reality from facts about the structure of true theories, The book starts with an overview of various approaches to metaphysics. Beginning with Quine's programmatic "On what there is", the first chapter then discusses the perils involved in going from language to metaphysics. It (...) criticises contemporary intuition-driven metaphysics, comments on naturalistic approaches, and then presents the main proposition put forward in the thesis: we should base metaphysics on model theory. In chapters 2 to 5, mathematical treatments are given of concepts that we need: theories, metaphysics, necessitation and semantics. These are used in chapters 6 and 7 to prove that, seen from a certain informative view point, any true theory will give rise to an isomorphism between that theory and the world. This conclusion is similar to Wittgenstein's in the Tractatus, but differs in that it places the structural relationship on the level of whole theories, rather than single propositions. (shrink)

This paper is largely exegetical/interpretive. My goal is to demonstrate that some criticisms that have been leveled against the program Gareth Evans constructs in The Varieties of Reference (Evans 1980, henceforth VR) misfire because they are based on misunderstandings of Evans’ position. First I will be discussing three criticisms raised by Tyler Burge (Burge, 2010). The first has to do with Evans’ arguments to the effect that a causal connection between a belief and an object is insufficient for that belief (...) to be about that object. A key part of Evans’ argument is to carefully distinguish considerations relevant to the semantics of language from considerations relevant to the semantics (so to speak) of thought or belief (to make the subsequent discussion easier, I will henceforth use ‘thought’ as a blanket term for the relevant mental states, including belief). I will argue that Burge’s criticisms depend on largely not taking account of Evans’ distinctions. Second, Burge criticizes Evans’ account of ‘informational content’ taking it to be inconsistent. I will show that the inconsistency Burge finds depends entirely on a misreading of the doctrine. Finally, Burge takes Evans to task for a perceived over-intellectualization in a key aspect of his doctrine. Burge incorrectly reads Evans as requiring that the subject holding a belief be engaged in certain overly intellectual endeavors, when in fact Evans is only attributing these endeavors to theorists of such a subject. Next, I turn to two criticisms leveled by John Campbell (Campbell, 1999). I will argue that Campbell’s criticisms are based on misunderstandings – though they do hit at deeper elements of Evans’ doctrine. First, Campbell reads Evans’ account of demonstrative thought as requiring that the subject’s information link to an object allows her to directly locate that object in space. Campbell constructs a case in which one tomato (a) is, because of an angled mirror, incorrectly seen as being at a location that happens to be occupied by an identical tomato (b). Campbell claims that Evans’ doctrines require us to conclude that the subject cannot have a demonstrative thought about the seen tomato (a), though it seems intuitively that such a subject would be able to have a demonstrative thought about that tomato, despite its location is inaccurately seen. I show that Evans’ position in fact allows that the subject can have a demonstrative thought about the causal-source tomato in this case because his account does not require that the location of demonstratively identified objects be immediately accurately assessed. What is crucial is that the subject have the ability to accurately discover the location. Second, Campbell criticizes Evans’ notion of a fundamental level of thought. I show that this criticism hinges on view of the nature and role of the fundamental level of thought that mischaracterizes Evans’ treatment of the notion. (shrink)

The relationship between classical and quantum theory is of central importance to the philosophy of physics, and any interpretation of quantum mechanics has to clarify it. Our discussion of this relationship is partly historical and conceptual, but mostly technical and mathematically rigorous, including over 500 references. For example, we sketch how certain intuitive ideas of the founders of quantum theory have fared in the light of current mathematical knowledge. One such idea that has certainly stood the test of time is (...) Heisenberg's `quantum-theoretical Umdeutung (reinterpretation) of classical observables', which lies at the basis of quantization theory. Similarly, Bohr's correspondence principle (in somewhat revised form) and Schroedinger's wave packets (or coherent states) continue to be of great importance in understanding classical behaviour from quantum mechanics. On the other hand, no consensus has been reached on the Copenhagen Interpretation, but in view of the parodies of it one typically finds in the literature we describe it in detail. On the assumption that quantum mechanics is universal and complete, we discuss three ways in which classical physics has so far been believed to emerge from quantum physics, namely in the limit h -> 0 of small Planck's constant (in a finite system), in the limit N goes to infinity of a large system with $N$ degrees of freedom (at fixed h), and through decoherence and consistent histories. The first limit is closely related to modern quantization theory and microlocal analysis, whereas the second involves methods of C*-algebras and the concepts of superselection sectors and macroscopic observables. In these limits, the classical world does not emerge as a sharply defined objective reality, but rather as an approximate appearance relative to certain ``classical" states and observables. Decoherence subsequently clarifies the role of such states, in that they are ``einselected", i.e. robust against coupling to the environment. Furthermore, the nature of classical observables is elucidated by the fact that they typically define (approximately) consistent sets of histories. This combination of ideas and techniques does not quite resolve the measurement problem, but it does make the point that classicality results from the elimination of certain states and observables from quantum theory. Thus the classical world is not created by observation (as Heisenberg once claimed), but rather by the lack of it. (shrink)

This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. It is a widespread view among philosophers that if we accept the B-theory, the commonsensical ‘endurance theory’ of persistence will have to be rejected. The endurance theory says (...) that objects persist through time by being wholly present at distinct times as numerically the same entity. Instead of endurantism, it has been argued, we have to adopt either ‘perdurantism’ or the ‘stage theory’. Perdurantism is the theory that objects are four-dimensional ‘space-time worms’ persisting through time by having distinct temporal parts at distinct times. The stage theory says that objects are instantaneous temporal parts (stages) of space-time worms, persisting by having distinct temporal counterparts at distinct times. In the thesis, it is argued that no good arguments have been provided for the conclusion that we are obliged to drop the endurance theory by acceptance of the B-theory. This conclusion stands even if the endurance theory incorporates the claim that objects endure through intrinsic change. It is also shown that perdurantism and the stage theory come with unwelcome consequences. -/- Paper I demonstrates that the main arguments for the view that objects cannot endure in B-time intrinsically unchanged fail. Papers II and III do the same with respect to the traditional arguments against endurance through intrinsic change in B-time. Paper III also contains a detailed account of the semantics of the tenseless copula, which occurs frequently in the debate. The contention of Paper IV is that four-dimensional space-time worms, as traditionally understood, are not suited to take dispositional predicates. In Paper V, it is shown that the stage theory needs to introduce an overabundance of persistence-concepts, many of which will have to be simultaneously applicable to a single object (qua falling under a single sortal), in order for the theory to be consistent. The final article, Paper VI, investigates the sense in which persistence can, as is sometimes suggested, be a ‘conventional matter’. It also asks whether alleged cases of ‘conventional persistence’ create trouble for the endurance theory. It is argued that conventions can only enter at a trivial semantic level, and that the endurance theory is no more threatened by such conventions than are its rivals. (shrink)

This paper observes that P. F. Strawson’s distinction between descriptive and revisionary metaphysics is a baffling one from the perspective of traditional metaphysics. If one thinks of metaphysics as the study of the fundamental nature of reality, it is bewildering to divide up metaphysics in this way. The paper then tries to show how the distinction is no longer bewildering if we deny that such study is possible.

The central motivating idea behind the development of this work is the concept of prespace, a hypothetical structure that is postulated by some physicists to underlie the fabric of space or space-time. I consider how such a structure could relate to space and space-time, and the rest of reality as we know it, and the implications of the existence of this structure for quantum theory. Understanding how this structure could relate to space and to the rest of reality requires, I (...) believe, that we consider how space itself relates to reality, and how other so-called "spaces" used in physics relate to reality. In chapter 2, I compare space and space-time to other spaces used in physics, such as configuration space, phase space and Hilbert space. I support what is known as the "property view" of space, opposing both the traditional views of space and space-time, substantivalism and relationism. I argue that all these spaces are property spaces. After examining the relationships of these spaces to causality, I argue that configuration space has, due to its role in quantum mechanics, a special status in the microscopic world similar to the status of position space in the macroscopic world. In chapter 3, prespace itself is considered. One way of approaching this structure is through the comparison of the prespace structure with a computational system, in particular to a cellular automaton, in which space or space-time and all other physical quantities are broken down into discrete units. I suggest that one way open for a prespace metaphysics can be found if physics is made fully discrete in this way. I suggest as a heuristic principle that the physical laws of our world are such that the computational cost of implementing those laws on an arbitrary computational system is minimized, adapting a heuristic principle of this type proposed by Feynman. In chapter 4, some of the ideas of the previous chapters are applied in an examination of the physics and metaphysics of quantum theory. I first discuss the "measurement problem" of quantum mechanics: this problem and its proposed solution are the primary subjects of chapter 4. It turns out that considering how quantum theory could be made fully discrete leads naturally to a suggestion of how standard linear quantum mechanics could be modified to give rise to a solution to the measurement problem. The computational heuristic principle reinforces the same solution. I call the modified quantum mechanics Critical Complexity Quantum Mechanics (CCQM). I compare CCQM with some of the other proposed solutions to the measurement problem, in particular the spontaneous localization model of Ghirardi, Rimini and Weber. Finally, in chapters 5 and 6, I argue that the measure of complexity of quantum mechanical states I introduce in CCQM also provides a new definition of entropy for quantum mechanics, and suggests a solution to the problem of providing an objective foundation for statistical mechanics, thermodynamics, and the arrow of time.

During the realist revival in the early years of this century, philosophers of various persuasions were concerned to investigate the ontology of truth. That is, whether or not they viewed truth as a correspondence, they were interested in the extent to which one needed to assume the existence of entities serving some role in accounting for the truth of sentences. Certain of these entities, such as the Sätze an sich of Bolzano, the Gedanken of Frege, or the propositions of Russell (...) and Moore, were conceived as the bearers of the properties of truth and falsehood. Some thinkers however, such as Russell, Wittgenstein in the Tractatus, and Husserl in the Logische Untersuchungen, argued that instead of, or in addition to, truth-bearers, one must assume the existence of certain entities in virtue of which sentences and/or propositions are true. Various names were used for these entities, notably 'fact', 'Sachverhalt', and 'state of affairs'. (1) In order not to prejudge the suitability of these words we shall initially employ a more neutral terminology, calling any entities which are candidates for this role truth-makers. (shrink)
