This thesis defends egalitarianism about knowledge and belief, on which neither is understood in terms of the other, from what I call the abductive argument. This argument is meant to favour views opposed to egalitarianism: doxasticism, on which knowledge is understood in terms of belief, and epistemicism, on which belief is understood in terms of knowledge. The abductive argument turns on the idea that doxasticism and epistemicism, by contrast with egalitarianism, explain certain data about knowledge and belief. I argue, however, (...) that no versions of doxasticism and epistemicism currently on offer are preferable to egalitarianism on abductive grounds. As part of my argument, I also defend the claim that knowledge, by contrast with belief, is an attitude to a fact and explore the implications of this claim for doxasticism and epistemicism.

Richard Holton has drawn attention to a new semantic universal, according to which (almost) no natural language has contrafactive attitude verbs. This semantic universal is part of an asymmetry between factive and contrafactive attitude verbs. Whilst factives are abundant, contrafactives are scarce. We propose that this asymmetry is partly due to a difference in learnability. The meaning of contrafactives is significantly harder to learn than that of factives. We tested our hypothesis by conducting a computational experiment using an artificial neural (...) network. The results of this experiment support our hypothesis. (shrink)

I develop a challenge for a widely suggested knowledge-first account of belief that turns, primarily, on unknowable propositions. I consider and reject several responses to my challenge and sketch a new knowledge-first account of belief that avoids it.

Can knowledge be defined? We expound an argument of John Cook Wilson's that it cannot. Cook Wilson's argument connects knowing with having the power to inquire. We suggest that if he is right about that connection, then knowledge is, indeed, indefinable.

In this review essay of Michelle Montague’s The Given we focus on the central thesis in the book: the awareness of awareness thesis. On that thesis, a state of awareness constitutively involves an awareness of itself. In Section 2, we discuss what the awareness of awareness thesis amounts to, how it contrasts with the transparency of experience, and how it might be motivated. In Section 3, we discuss one of Montague’s two theoretical arguments for the awareness of awareness thesis. A (...) view that accepts the awareness of awareness thesis, Montague argues, is to be preferred over competing views because it outperforms them in accounting for the property attributions one makes in perceptual experience. We suggest that it is not clear that this argument for the awareness of awareness thesis is successful. Finally, in Section 4 we consider the relation between Montague’s view of color experience and what she calls Strawson’s datum, arguing that Montague may not be able to explain this datum as straightforwardly as she supposes. This, we suggest, threatens Montague’s second theoretical argument for the awareness of awareness thesis. (shrink)

The last decade has witnessed the beginnings of a remarkable convergence of Husserlian phenonenology and analytic philosophy of language, and the present volumes provide original and important texts of the phenomenological philosophy of language. Powerfully influenced by the writings of the early Husserl, Reinach fashioned Husserl’s ideas into a rigorous analytical methodology of his own, which he applied in particular to problems in logic and the theory of knowledge, and to the philosophies of law and psychology. The central role of (...) the concept of state of affairs in Reinach’s philosophy will bring to mind immediately the formal ontology of Wittgenstein’s Tractatus. Reinach’s most significant contribution, however, is contained in his The a priori foundations of civil law (1913), above all in the detailed analysis of the a priori structure of the act of promising. This amounts to an elaborate phenomenological theory of speech acts which anticipates, and in some respects goes beyond, the later theories of Austin and Searle. The present edition is in two volumes. Volume 1, which includes a biographical and thematic introduction by the editors, contains critical editions of those pieces published by Reinach himself. Volume II is a collection of all those items in Reinach’s surviving Nachlass which are in publishable form, including a number of important pieces not hitherto obtainable on such themes as ethical predicates, speech acts (“soziale Akte”), perception and the theory of number, together with a comprehensive sketch of the problems in the theory of knowledge, logic and ethics. Appended to this is a text-critical apparatus which also contains extensive discussions of the origins and sources of the materials in question. (shrink)

This paper offers a refutation of P. Duhem's thesis that the falsifiability of an isolated empirical hypothesis H as an explanans is unavoidably inconclusive. Its central contentions are the following: 1. No general features of the logic of falsifiability can assure, for every isolated empirical hypothesis H and independently of the domain to which it pertains, that H can always be preserved as an explanans of any empirical findings O whatever by some modification of the auxiliary assumptions A in conjunction (...) with which H functions as an explanans. For Duhem cannot guarantee on any general logical grounds the deducibility of O from an explanans constituted by the conjunction of H and some revised non-trivial version R of A: the existence of the required set R of collateral assumptions must be demonstrated for each particular case. 2. The categorical form of the Duhemian thesis is not only a non-sequitur but actually false. This is shown by adducing the testing of physical geometry as a counterexample to Duhem in the form of a rebuttal to A. Einstein's geometrical articulation of Duhem's thesis. 3. The possibility of a quasi a priori choice of a physical geometry in the sense of Duhem must be clearly distinguished from the feasibility of a conventional adoption of such a geometry in the sense of H. Poincare. And the legitimacy of the latter cannot be invoked to save the Duhemian thesis from refutation by the foregoing considerations. (shrink)

Cette traduction inedite de l'oeuvre principale d'Adolf Reinach (1883-1917) apporte des contributions fondamentales a divers champs de la connaissance. Disciple de Husserl, Reinach propose une interpretation du monde social qui engage la phenomenologie sur le terrain des actes sociaux et des experiences individuelles qui les accompagnent, afin d'isoler les structures a priori qui sont au principe meme du droit positif. Le travail de Reinach s'inscrit egalement dans un champ d'analyse philosophique et linguistique centre sur les enonces dits performatifs, baptises (...) tels par Austin quelques decennies plustard.

According to some cosmologists, the big bang cosmogony and even the (now largely defunct) steady-state theory pose a scientifically insoluble problem of matter-energy creation. But I argue that the genuine problem of the origin of matter-energy or of the universe has been fallaciously transmuted into the pseudo-problem of creation by an external cause. A fortiori, it emerges that the initial "true" and "false" vacuum states of quantum cosmology do not vindicate biblical divine creation ex nihilo at all.

Engaging stakeholders in policy making and supporting policy development with advanced information and communication technologies including policy simulation is currently high on the agenda of research. In order to involve stakeholders in providing their input to policy modeling via online means, simple techniques need to be employed such as scenario technique. Scenarios enable stakeholders to express their views in narrative text. At the other end of policy development, a frequently used approach to policy modeling is agent-based simulation. So far, effective (...) support to transform narrative text input to formal simulation statements is not widely available. In this paper, we present a novel approach to support the transformation of narrative texts via conceptual modeling into formal simulation models. The approach also stores provenance information which is conveyed via annotations of texts to the conceptual model and further on to the simulation model. This way, traceability of information is provided, which contributes to better understanding and transparency, and therewith enables stakeholders and policy modelers to return to the sources that informed the conceptual and simulation model. In this paper, we present the consistent conceptual description (CCD) as conceptual modeling approach to bridge the gap between narrative texts and formal policy models. The CCD meta-model with the underlying vocabulary for describing policy contexts is detailed. A case study introduces the application of the approach in the Open Collaboration for Policy Modeling project. (shrink)

In der Geschichte der Philosophie gibt es nur wenige Namen, mit denen sich so viel Ungewohnliches, aber auch Ungereimtes, ja Paradoxes verbindet wie mit dem Namen Wittgenstein. Fur den Mann auf der StraSSe meist ein ganzlich Unbekannter, ist Wittgenstein fur viele Fachleute der Philosoph schlechthin. ER zahlt zu den meistzitierten Denkern des 20. JAhrhunderts, obwohl er in seinem Leben nur einige Dutzend Seiten veroffentlicht hat: er wurde seit seinem Tode zum Star einer neuen philosophischen Tradition, wo gerade er uns doch (...) von der traditionellen Philosophie befreien wollte. EIne vollstandige Bibliographie der Wittgenstein-Literatur wurde mehrere tausend Titel umfassen, und standig werden neue Abhandlungen uber Wittgenstein und seine Philosophie veroffentlicht. (shrink)

Prompted by the "Panel Discussion of Grünbaum's Philosophy of Science" (Philosophy of Science 36, December, 1969) and other recent literature, this essay ranges over major issues in the philosophy of space, time and space-time as well as over problems in the logic of ascertaining the falsity of a scientific hypothesis. The author's philosophy of geometry has recently been challenged along three main distinct lines as follows: (i) The Panel article by G. J. Massey calls for a more precise and more (...) coherent account of the Riemannian conception of an intrinsic as opposed to an extrinsic metric, which the author has invoked as his basis for the distinction between non-conventional and convention-laden ascriptions of metrical equality and inequality; (ii) the latter distinction has been claimed to suffer from the liabilities of the so-called "standard conception" of scientific theories [36]; and (iii) pursuant to H. Putnam's "An Examination of Grünbaum's Philosophy of Geometry" [56], J. Earman [16, 17] and R. Swinburne [65] have contended that the difference between intrinsic and extrinsic metrics is scientifically unilluminating, and that the associated distinction between non-conventional and convention-laden metrical comparisons does not have the kind of relevance to extant scientific theories that the author has claimed for it. The essay consists of two installments. The present installment, comprising the Introduction and Part A, is devoted to the clarification, correction and further development of the author's prior writings on the philosophy of geometry. Its main objective is constructive elaboration rather than offering polemics. But rebuttals to Earman, [16, 17], Swinburne [65] and Demopoulos [13] are included, because their inclusion conduced to clarity in giving the new exposition. Part B is to appear in a subsequent issue and will be devoted to replies to critiques contained in the Panel Discussion and in other recent literature. It will range over issues in the philosophy of geometry and in the logic of ascertaining the falsity of a scientific hypothesis. By way of merely elliptical anticipation of much more precise statements given in Part A, section 3(ii), the Introduction dissociates the notion of convention-ladenness developed in Part A from the quite different notion integral to the so-called "standard conception" of scientific theories. Thereby, the Introduction prepares the ground for seeing, as a corollary to Part A, section 3(ii), that the notion advocated in the present essay has nothing to fear from the following fact, noted by C. G. Hempel ([36]; cf. also his 1970 Carus Lectures): "even though a sentence may originally be introduced as true by stipulation, it soon joins the club of all other member-statements of the theory and becomes subject to revision in response to further empirical findings and theoretical developments." Part A, which begins with a fairly detailed table of contents, endeavors to meet the aforementioned three-fold challenge to the author's philosophy of geometry. Massey's call for the provision of clear and detailed characterizations of intrinsic and extrinsic metrics is answered with the invaluable aid rendered personally by Massey himself. These characterizations are shown to permit a precise explication of the portions of Riemann's Inaugural Dissertation relevant to (1) Riemann's brilliant anticipation of Einstein's dynamical conception of physical geometry, and (2) the author's philosophical characterization of the metrics and geometries of space, time, and space-time {section 2(c)}. A byproduct of the analysis is to raise two major philosophical doubts concerning Clifford's sketch of a so-called "space-theory of matter" as elaborated in J. A. Wheeler's relativistic geometrodynamics. That theory's vision of understanding matter as a manifestation of empty curved space is questioned in regard to (1) the existence of an intra-geometrodynamic basis for individuating the metrically homogeneous world points of its space-time manifold {section 1(a)}, and (2) the compatibility of the theory with the Riemannian metrical philosophy apparently espoused by its proponents {section 2(c)(i)}.

It is a commonplace in the analytic geometry of physical space-time that an extended straight line segment, having positive length, is treated as “consisting of” unextended points, each of which has zero length. Analogously, time intervals of positive duration are resolved into instants, each of which has zero duration.
