Dr. Marjorie Grene has argued that criteria taken from a personalist philosophy of science have regulative force in the dispute between orthogenetic and synthetic or neo-Darwinian theories of evolution, and that these criteria commend the acceptance of the orthogenetic position. Grene's position includes two basically correct theses concerning the limitations of operationism and reductionism. However, she fails to show that personalist tenets are necessary for the validation of these two theses. Moreover, the proposed modifications of evolutionary theory depend upon additional (...) premisses: that biology must study individuals rather than populations, and that the synthetic theory must prove that natural selection and mutation are the only possible factors for control of the direction of evolutionary change. The evidence for these premisses is called into question. (shrink)

This is one of a series of reports of a case study of the convergence of molecular neurobiology and cognitive studies of Pavlovian conditioning. Here, I examine a fundamental disagreement between major centers of research representing each of these two domains and analyze it in terms of a hybrid historical, sociological, and philosophical concept of effective scientific communication. The specific example considered is found to fall short of the criteria for effective communication because of the absence of explicit, published reciprocity (...) in the exchange of critical appraisal of results and in requests for reformulation of investigative priorities, research designs, and criteria of scientific adequacy. The situation is dramatized and a remedy proposed by means of an imaginary dialogue linking the two research centers. The paper raises a number of key issues. means for appraising the epistemic status of explanations putatively linking domains in the absence of effective scientific communication; the influence of socially contingent features of the cognitive perspectives of the relatively small number of scientific translators responsible for such communication between domains; and the status of dialogues of the sort presented here, e.g., as idealized philosophical critique or conjectural history of the future of science.

A basic question confronting programs in the sociology of science is: "Can the thesis that cognitive claims are socially determined be interpreted in a way that preserves the credibility of the sociology of science, when that thesis is reflexively applied to the sociology of science?" That question is approached here by means of a critical comparison of two versions of the " strong programme" in the sociology of knowledge. The key difference is the effort in one of the two versions (...) to develop a context within which to articulate the distinction of science and ideology. (shrink)

I write here about how the visible and the invisible intertwine in painting: in theory and in praxis – primarily the praxis of my own painting. Philosophers are rarely asked to discuss, much less to show in public, what they do avocationally rather than professionally. I was drawn to the invitation of the Merleau-Ponty Circle to exhibit my painting and to talk about what I do when I am not writing or teaching philosophy. It has offered a rare chance to (...) catch up with myself – with the painter in me. I started in art long before I turned to philosophy. It was my first love and is still my intermittent passion. I have not hidden it from others altogether – I have shown my work in various group shows– but it would be more accurate to say that I have hidden it from myself. Talking about my art work in the context of this Circle comes at a very welcome moment in which I am in the process of determining where I shall go with the rest of my life as it shortens down: ars longa, vita brevis.J’écris ici à propos de la manière dont le visible et l’invisible s’entrelacent dans la peinture : en théorie et en pratique, prioritairement dans ma propre pratique de la peinture. On demande rarement aux philosophes de discuter, et encore moins de montrer en public, ce qu’ils font en amateurs plutôt que professionnellement. J’ai été entraîné par l’invitation du Merleau-Ponty Circle à exposer ma peinture et à parler de ce que je fais lorsque je n’écrit pas et n’enseigne pas la philosophie. Cela m’a offert une chance rare de me retrouver moi-même, le peintre en moi. J’ai commencé dans l’art bien avant de me tourner vers la philosophie. C’était mon premier amour c’est encore ma passion intermittente. Je ne l’ai pas caché, puisque j’ai montré mon travail dans plusieurs expositions collectives. Ce serait plus juste de dire que je l’ai caché de moi-même. Parler de mes oeuvres d’art dans le contexte du Merleau-Ponty Circle arrive à un moment tout à fait bienvenu, où je suis en train de réfléchir à la suite de ma vie, puisqu’elle raccourcit : ars longa, vita brevis.In questo articolo tratto di come il visibile e l’invisibile si intreccino in pittura, nella teoria come nella pratica, e in particolare nella mia pratica di pittura. Raramente ai filosofi viene chiesto di discutere, e ancor più raramente di mostrare pubblicamente, ciò che essi fanno in ambito amatoriale e non professionale. Sono rimasto molto colpito dall’invito del Merleau-Ponty Circle a esporre i miei dipinti e a parlare dell’attività che svolgo quando non scrivo o non insegno filosofia. Questo invito mi ha fornito un’opportunità rara per riprendere contatto con me stesso – con il pittore che è in me. Mi sono avvicinato all’arte molto prima di rivolgermi alla filosofia. L’arte è stato il mio primo amore ed è ancora la mia passione intermittente. Non l’ho mai tenuta nascosta agli altri – ho presentato il mio lavoro in numerose mostre collettive; forse sarebbe più corretto dire che l’ho nascosta a me stesso.La possibilità di parlare della mia arte in occasione del Merleau-Ponty Circle si è presentata in un momento molto propizio, in cui mi trovo a domandarmi quale strada percorrere in quello che resta della mia vita che a mano a mano si accorcia: ars longa, vita brevis.

This book tackles the issues that arise in connection with intensional logic -- a formal system for representing and explaining the apparent failures of certain important principles of inference such as the substitution of identicals and existential generalization -- and intentional states --mental states such as beliefs, hopes, and desires that are directed towards the world. The theory offers a unified explanation of the various kinds of inferential failures associated with intensional logic but also unifies the study of intensional contexts (...) and intentional states by grounding the explanation of both phenomena in a single theory. When an axiomatized realm of abstract entities is added to the metaphysical structure of the world, we can use them to identify and individuate the contents of directed mental states. The special abstract entities can be viewed as the objectified contents of mental files, and they play a crucial role in the analysis of truth conditions of the sentences involved in inferential failures.

In this book, Zalta attempts to lay the axiomatic foundations of metaphysics by developing and applying a (formal) theory of abstract objects. The cornerstones include a principle which presents precise conditions under which there are abstract objects and a principle which says when apparently distinct such objects are in fact identical. The principles are constructed out of a basic set of primitive notions, which are identified at the end of the Introduction, just before the theorizing begins. The main reason for (...) producing a theory which defines a logical space of abstract objects is that it may have a great deal of explanatory power. It is hoped that the data explained by means of the theory will be of interest to pure and applied metaphysicians, logicians and linguists, and pure and applied epistemologists. (shrink)

The Nature of God explores a perennial problem in the philosophy of religion.

Some recently-proposed counterexamples to the traditional definition of essential property do not require a separate logic of essence. Instead, the examples can be analysed in terms of the logic and theory of abstract objects. This theory distinguishes between abstract and ordinary objects, and provides a general analysis of the essential properties of both kinds of object. The claim ‘x has F necessarily’ becomes ambiguous in the case of abstract objects, and in the case of ordinary objects there are various ways (...) to make the definition of ‘F is essential to x’ more fine-grained. Consequently, the traditional definition of essential property for abstract objects in terms of modal notions is not correct, and for ordinary objects the relationship between essential properties and modality, once properly understood, addresses the counterexample.

HISTORIANS of psychology are almost unanimously agreed on one point: that psychology is a relatively new science. There may be some disagreement as to when it started--with Weber, or Fechner, or Wundt, or James--but there is almost no dissent from the proposition that psychology as a scientific discipline is less than one and one-half centuries old. Many earlier writers are often discussed in histories of psychology, but invariably they are called speculators, or philosophers, as opposed to scientists. We believe that (...) this is an incorrect appraisal of the career of psychological research. To demonstrate our point, we propose to show how one key psychological idea from Descartes' work has had an extensive and robust scientific history. If it is true that this Cartesian idea has had great influence in science, then many claims concerning the history of psychology will need to be reconsidered. Not everything which happened in psychology prior to the nineteenth century was speculative, nor is everything which happened later scientific. Even more importantly, if Descartes' idea has been of such central concern to several hundred years of research, it must be treated as an important claim about the way the world is, as a law of nature.

The foregoing set of theorems forms an effective foundation for the theory of situations and worlds. All twenty-five theorems seem to be basic, reasonable principles that structure the domains of properties, relations, states of affairs, situations, and worlds in true and philosophically interesting ways. They resolve 15 of the 19 choice points defined in Barwise (1989) (see Notes 22, 27, 31, 32, 35, 36, 39, 43, and 45). Moreover, important axioms and principles stipulated by situation theorists are derived (see Notes (...) 33, 37, and 38). This is convincing evidence that the foregoing constitutes a theory of situations. Note that worlds are just a special kind of situation, and that the basic theorems of world theory, which were derived in previous work, can still be derived in this situation-theoretic setting. So there seems to be no fundamental incompatibility between situations and worlds — they may peacably coexist in the foundations of metaphysics. The theory may therefore reconcile two research programs that appeared to be heading off in different directions. And we must remind the reader that the general metaphysical principles underlying our theory were not designed with the application to situation theory in mind. This suggests that the general theory and the underlying distinction have explanatory power, for they seem to relate and systematize apparently unrelated phenomena. (shrink)

In this paper I am going to try to indicate my notion concerning the nature and subject-matter of psychology. I am a behaviorist. I hold that psychology does not seek descriptions and intercommunications concerning immediate experience per se. Such descriptions and attempts at direct intercommunications may be left to the arts and to metaphysics. Psychology seeks, rather, the objectively stateable laws and processes governing behavior. Organisms, human and sub-human, come up against environmental stimulus situations and to these stimulus situations they, (...) after longer or shorter intervals of time, behave. The laws and processes determining this their behavior are stateable in objective terms. Even in the cases where the organism is oneself, these determining causal factors can and must—for the purposes of psychology—be stated objectively. It is true that in these latter instances, in which the animal in question is oneself, one may in one's rôle, not of a psychologist, but of an artist or a metaphysician, attempt to describe and convey to another man one's own facts of immediate experience. But such a description and report of immediate experiences, except in so far as this report is itself a form of behavior and therefore like all other behaviors the basis for an investigation of the objective laws and processes underlying it, essentially new to the picture. Experience qua experience, while of concern and interest to the man in the street, the philosopher and the poet, does not enter as such into the laws and equations of psychology,—in so far, at any rate, as psychology is to be considered as a science.

The oddities in lottery cases and Moore’s paradox appear to support the knowledge account of assertion, according to which one should assert only what one knows. This paper preserves an emphasis on epistemic norms but presents grounds for an alternative explanation. The alternative divides the explanandum, explaining the error in lottery and Moorean assertions with one move and their deeper incoherence with another. The error derives from a respect in which the assertions are uninformative: the speaker is not being appropriately (...) responsive to her addressee’s epistemic needs. And the incoherence derives from a deeper respect in which lottery and some (but not all) Moorean assertions are uninformative: it is difficult to see how the speaker’s assertion could express any judgment she has made or would relevantly make, since she transparently lacks epistemic authority to inform any conceivable interlocutor on the subject. This diagnosis suggests an epistemic approach not directly to assertion but to judgment. Without judging that p, how could a speaker be in the business of informing her addressee that p? If the speaker transparently lacks authority to inform anyone whether p – to give anyone her word that p – how could she without confusion count as judging that p? (shrink)

The author describes an interpreted modal language and produces some clear examples of logical and analytic truths that are not necessary. These examples: (a) are far simpler than the ones cited in the literature, (b) show that a popular conception of logical truth in modal languages is incorrect, and (c) show that there are contingent truths knowable ``a priori'' that do not depend on fixing the reference of a term.

Previous assurance-theoretic treatments of testimony have not adequately explained how the transmission of warrant depends specifically on the speaker’s mode of address – making it natural to suspect that the interpersonal element is not epistemic but merely psychological or action-theoretic. I aim to fill that explanatory gap: to specify exactly how a testifier’s assurance can create genuine epistemic warrant. In doing so I explain (a) how the illocutionary norm governing the speech act proscribes not lies but a species of bullshit, (...) in an extension of Harry Frankfurt’s sense, (b) how that norm makes testimony fully second-personal, in Stephen Darwall’s sense, or bipolar, in Michael Thompson’s sense, and (c) how that species of second-personality or bipolarity is more fundamental than the practical species that Darwall and Thompson discuss. One attraction of this new Assurance View of testimony is that it allows us to reconceptualize the natures of normativity and responsibility more generally, viewing the assurance as implicating us in normative relations of recognition, and therefore of justice, that are not yet moralized with reactive attitudes.

This paper argues for the value of philosophers in a school of social sciences within a university, for fixing what I call disciplinary constitutions. A disciplinary constitution is a statement of “How our discipline works: how we achieve the ends of our discipline.” A lot of people depend on a constitution, but such a thing usually runs into problems and philosophers can identify these problems and propose solutions. I suggest that it is essential for the autonomy of an ambitious school (...) to be able to do such work internally. (shrink)

An assurance theory of trust begins from the act of assurance – whether testimonial, advisorial or promissory – and explains trust as a cognate stance of resting assured. My version emphasizes the risks and rewards of trust. On trust’s rewards, I show how an assurance can give a reason to the addressee through a twofold exercise of ‘normative powers’: (i) the speaker thereby incurs an obligation to be sincere; (ii) if the speaker is trustworthy, she thereby gives her addressee the (...) reason. Each claim is controversial; my contribution lies in how I defend them together, linking the sincerity obligation to the provision of reasons. On trust’s risks, I defend a popular thesis about the nature of trust – that trust differs from mere reliance in how it risks betrayal – against the objection that the thesis ‘moralizes’ trust. Such betrayal need not be moral, I argue, because it may derive entirely from how the assurance purports to provide a reason. (shrink)

In sentences like Every teacher laughed we think of every teacher as a unary (=type (1)) quantifier - it expresses a property of one place predicate denotations. In variable binding terms, unary quantifiers bind one variable. Two applications of unary quantifiers, as in the interpretation of No student likes every teacher, determine a binary (= type (2)) quantifier; they express properties of two place predicate denotations. In variable binding terms they bind two variables. We call a binary quantifier Fregean (or (...) reducible) if it can in principle be expressed by the iterated application of unary quantifiers. In this paper we present two mathematical properties which distinguish non-Fregean quantifiers from Fregean ones. Our results extend those of van Benthem (1989) and Keenan (1987a). We use them to show that English presents a large variety of non-Fregean quantifi ers. Some are new here, others are familiar (though the proofs that they are non-Fregean are not). The main point of our empirical work is to inform us regarding the types of quantification natural language presents - in particular (van Benthem, 1989) that it goes beyond the usual (Fregean) analysis which treats it as mere iterated application of unary quantifiers. Secondarily, our results challenge linguistic approaches to "Logical Form" which constrain variable binding operators to "locally" bind just one occurrence of a variable, e.g., the Bijection Principle (BP) of Koopman and Sportiche (1983). The BP (correctly) blocks analyses like For which x, x's mother kissed x? for Who did his mother kiss? since For which x would locally bind two occurrences of x. But some of our irreducible binary quantifiers are naturally represented by operators which do locally bind two variables. This paper is organized as follows: Section 1 provides an explicit formulation of our questions of concern. Section 2 classifies the English constructions which we show to be non-Fregean. Section 3 presents the mathematical properties which test for non-Fregean quantification and applies these tests to the constructions in Section 2. Proofs of the mathema tical properties are given in the Appendix. (shrink)

This paper examines Descartes' problematic relational theory of motion, especially when viewed within the context of his dynamics, the Cartesian natural laws. The work of various commentators on Cartesian motion is also surveyed, with particular emphasis placed upon the recent important texts of Garber and Des Chene. In contrast to the methodology of most previous interpretations, however, this essay employs a modern "spacetime" approach to the problem. By this means, the role of dynamics in Descartes' theory, which has often been (...) neglected in favor of kinematic factors, is shown to be central to finding a solution to the puzzle of Cartesian motion.

In its approach to fiction and fictional discourse, pretense theory focuses on the behaviors that we engage in once we pretend that something is true. These may include pretending to name, pretending to refer, pretending to admire, and various other kinds of make-believe. Ordinary discourse about fictions is analyzed as a kind of institutionalized manner of speaking. Pretense, make-believe, and manners of speaking are all accepted as complex patterns of behavior that prove to be systematic in various ways. In this (...) paper, I attempt to show: (1) that this systematicity is captured in the basic distinctions and representations that are central to the formal theory of abstract objects, and (2) that this formal theory need not be interpreted platonistically, but may instead have an interpretation on which the `objects' of the theory are things that pretense theorists already accept, namely, complex patterns of linguistic behavior. The surprising conclusion, then, is that a certain Wittgensteinian approach to meaning (e.g., the meaning of a term like `Holmes' is constituted by its pattern of use) bears an interesting relationship to a formal metaphysical theory and the semantic analyses of discourse constructed in terms of that theory---the former offers a naturalized interpretation of the latter, yet the latter makes the former more precise.

We address how listeners perceive temporal regularity in music performances, which are rich in temporal irregularities. A computational model is described in which a small system of internal self‐sustained oscillations, operating at different periods with specific phase and period relations, entrains to the rhythms of music performances. Based on temporal expectancies embodied by the oscillations, the model predicts the categorization of temporally changing event intervals into discrete metrical categories, as well as the perceptual salience of deviations from these categories. The (...) model's predictions are tested in two experiments using piano performances of the same music with different phrase structure interpretations (Experiment 1) or different melodic interpretations (Experiment 2). The model successfully tracked temporal regularity amidst the temporal fluctuations found in the performances. The model's sensitivity to performed deviations from its temporal expectations compared favorably with the performers' structural (phrasal and melodic) intentions. Furthermore, the model tracked normal performances (with increased temporal variability) better than performances in which temporal fluctuations associated with individual voices were removed (with decreased variability). The small, systematic temporal irregularities characteristic of human performances (chord asynchronies) improved tracking, but randomly generated temporal irregularities did not. These findings suggest that perception of temporal regularity in complex musical sequences is based on temporal expectancies that adapt in response to temporally fluctuating input. (shrink)

In the debate about the nature and identity of possible worlds, philosophers have neglected the parallel questions about the nature and identity of moments of time. These are not questions about the structure of time in general, but rather about the internal structure of each individual time. Times and worlds share the following structural similarities: both are maximal with respect to propositions (at every world and time, either p or p is true, for every p); both are consistent; both are (...) closed (every modal consequence of a proposition true at a world is also true at that world, and every tense-theoretic consequence of a proposition true at a time is also true at that time); just as there is a unique actual world, there is a unique present moment; and just as a proposition is necessarily true iff true at all worlds, a proposition is eternally true iff true at all times. In this paper, I show that a simple extension of my theory of worlds yields a theory of times in which the above structural similarities between the two are consequences. (shrink)

In this paper, we describe "metaphysical reductions", in which the well-defined terms and predicates of arbitrary mathematical theories are uniquely interpreted within an axiomatic, metaphysical theory of abstract objects. Once certain (constitutive) facts about a mathematical theory T have been added to the metaphysical theory of objects, theorems of the metaphysical theory yield both an analysis of the reference of the terms and predicates of T and an analysis of the truth of the sentences of T. The well-defined terms and (...) predicates of T are analyzed as denoting abstract objects and abstract relations, respectively, in the background metaphysics, and the sentences of T have a reading on which they are true. After the technical details are sketched, the paper concludes with some observations about the approach. One important observation concerns the fact that the proper axioms of the background theory abstract objects can be reformulated in a way that makes them sound more like logical axioms. Some philosophers have argued that we should accept (something like) them as being logical. (shrink)

Kant is widely acknowledged as the greatest philosopher of modern times. He undertook his famous critical turn to save human freedom and morality from the challenge of determinism and materialism. Intertwined with his metaphysical interests, however, he also had theological commitments, which have received insufficient attention. He believed that man is a fallen creature and in need of ‘redemption’. He intended to provide a fortress protecting religious faith from the failure of rationalist metaphysics, from the atheistic strands of the Enlightenment, (...) from the new mathematical science of nature, and from the dilemmas of Christian theology itself. Kant was an epistemologist, a philosopher of mind, a metaphysician of experience, an ethicist and a philosopher of religion. But all this was sustained by his religious faith. This book aims to recover the focal point and inner contradictions of his thought, the ‘secret thorn’ of his metaphysics. It first locates Kant in the tradition of reflection on the human weakness from Luther to Hume, and then engages in a critical, but charitable, manner with Kant’s entire pre-critical work, including his posthumous fragments. Special attention is given to The Only Possible Ground, one of the most difficult, interesting and underestimated of Kant’s works. The book takes its cue from an older approach to Kant, but also engages with recent Anglophone and continental scholarship, and deploys modern analytical tools to make sense of Kant. What emerges is an innovative and thought-provoking interpretation of Kant’s metaphysics, set against the background of forgotten religious aspects of European philosophy. (shrink)

This paper has two main aims: first, to set forth an analysis of Timaeus 48E-52D and then to explore the significance of those pages for our understanding of Plato’s metaphysics. Students of the “Receptacle” in Plato’s Timaeus have given close attention to the many metaphors he offers in his explanation of its nature. Less attention has been given to the overall structure of the passage in which he presents it. In this paper, I attempt to show that Plato’s exposition there (...) exhibits a coherent and very careful design. But once that design is grasped, it can be seen that his extended account of the Receptacle must properly be understood to treat a rather different subject: the nature of an image, rather than the nature of the Receptacle, is the focal concern uniting the whole of 48E-52D.

This essay explores the vexed issue of individual corporeal substance in Descartes' natural philosophy. Although Descartes' often referred to individual material objects as separate substances, the constraints on his definitions of matter and substance would seem to favor the opposite view; namely, that there exists only one corporeal substance, the plenum. In contrast to this standard interpretation, however, it will be demonstrated that Descartes' hypotheses make a fairly convincing case for the existence of individual material substances; and the key to (...) this new found individuation is a long neglected set of passages in the Principles of Philosophy.
