This target article presents a new computational theory of explanatory coherence that applies to the acceptance and rejection of scientific hypotheses as well as to reasoning in everyday life, The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions. A hypothesis coheres with propositions that it explains, or that explain it, or that participate with it in explaining other propositions, or that offer analogous explanations. Propositions are incoherent with each other if they (...) are contradictory, Propositions that describe the results of observation have a degree of acceptability on their own. An explanatory hypothesis is acccpted if it coheres better overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which treats hypothesis evaluation as a constraint satisfaction problem. Inputs about the explanatory relations are used to create a network of units representing propositions, while coherende and incoherence relations are encoded by excitatory and inbihitory links. ECHO provides an algorithm for smoothly integrating theory evaluation based on considerations of explanatory breadth, simplicity, and analogy. It has been applied to such important scientific cases as Lovoisier's argument for oxygen against the phlogiston theory and Darwin's argument for evolution against creationism, and also to cases of legal reasoning. The theory of explanatory coherence has implications for artificial intelligence, psychology, and philosophy. (shrink)

In On What Matters, Derek Parfit defends a new metaethical theory, which he calls non-realist cognitivism. It claims that normative judgments are beliefs; that some normative beliefs are true; that the normative concepts that are a part of the propositions that are the contents of normative beliefs are irreducible, unanalysable and of their own unique kind; and that neither the natural features of the reality nor any additional normative features of the reality make the relevant normative beliefs true. The aim (...) of this article is to argue that Parfit’s theory is problematic because its defenders have no resources to make sense of the nature of normative truth, which is an essential element of their view. I do this by showing how the traditional theories of truth are not available for the non-realist cognitivists. (shrink)

I start from Phillips' discussion of Rhees's dissatisfaction with the idea of a language‐game. Then, from a rereading of Moore, I go on to exemplify interconnected uses of the expressions “language‐game,”“recurrent procedure,”“world‐picture,”“formal procedure,”“agreement in judgment,”“genre picture” and “form of life.” The discussion is related to sense perception, our knowledge of time and space, and the picture‐theory. These topics connect with Wittgenstein's earlier treatment of the will – which changed markedly later. The subtext (in footnotes) confronts (i) the sceptical methods of (...) Descartes and Hume with the grammatical methods of Leibniz, Kant and Wittgenstein, and (ii) the realism of Leibniz and the Tractatus with the transcendental idealism of Kant. My conclusion is that, although the method of Wittgenstein's later work remains in a sense grammatical, (i) in its new form it can free us from the conviction that the intellect can and must resolve one way or the other the conflicts that arise in the course of the latter confrontation, and that (ii), although release from such a conviction is to be seen as the aim of philosophical discourse in general, it allows philosophy to retain its overriding significance. A positive element in that lies in the respect the method demands for that in a human life which is transcendental to the activity of scientific theorising: respect, therefore, for the unique perspective of the individual historical agent.

It is fairly well known that Wittgenstein's criticisms of Russell's multiple‐relation theory of judgement had a devastating effect on the latter's philosophical enterprise. The exact nature of those criticisms however, and the explanation for the severity of their consequences, has been a source of confusion and disagreement amongst both Russell and Wittgenstein scholars. In this paper, I offer an interpretation of those criticisms which shows them to be consonant with Wittgenstein's general critique of Russell's conception of logic and which serves (...) to elucidate some of the notoriously enigmatic passages of the Tractatus. In particular, I seek to show the continuity of Wittgenstein's criticisms of the theory of judgement with his remarks on Russell's paradox and the theory of types. In addition, I place these issues in the context of Russell's own philosophical ambitions in order to reveal the deep divisions between the two over the nature of logical form and the analysis of propositional content.

This article puts forward a revisionary reading of Hegel's reception in Britain at the turn of the nineteenth century, in suggesting that the stance of the British Hegelians is very close to the sort of non-metaphysical or category theory interpretations that have been in vogue amongst contemporary commentators. It is shown that the British Hegelians arrived at this position as a way of responding to the hostile existentialist reaction to Hegel begun by Schelling in the 1840s, which led them to (...) abandon the standard Neoplatonic reading of his idealism, and arrive at the sort of non- metaphysical account which is most fully developed by J M E McTaggart in his interpretation of Hegel's Logic.

The author argues that coherence views of justification, in spite of their crucial insight into the interpenetration of our beliefs, neglect a key constraint on justification: they are unable to accommodate the epistemic significance of experience. Epistemic justification is not just a function of our beliefs and their interrelations. Both, beliefs and experiences, are relevant to the justification of an empirical belief. Experience is not itself a form of belief or disposition to believe; it cannot be analyzed in doxastic terms. (...) And, yet, nondoxastic experiences play a justificatory role, not merely a causal role. The positive epistemic status of a perceptual belief depends upon being appeared to in appropriate ways. It is important that, for an ordinary perceptual belief to be justified, one does not have to believe that one is appeared to in these ways. It is the experiences themselves, the ways of being appeared to, not our beliefs about them, that are required for justification. (shrink)

Between April and November 1912, Bertrand Russell and Ludwig Wittgenstein were engaged in a joint philosophical program. Wittgenstein‘s meeting with Gottlob Frege in December 1912 led, however, to its dissolution – the joint program was abandoned. Section 2 of this paper outlines the key points of that program, identifying what Russell and Wittgenstein each contributed to it. The third section determines precisely those features of their collaborative work that Frege criticized. Finally, building upon the evidence developed in the preceding two (...) sections, section 4 recasts along previously undeveloped lines Wittgenstein‘s logical–philosophical discoveries in the two years following his encounter with Frege in 1912. The paper concludes, in section 5, with an overview of the dramatic consequences the Frege-Wittgenstein critique had for Russell‘s philosophical development. (shrink)

Hearsay or indirect testimony receives little discussion even today in epistemology, and yet it represents one of the cardinal modes for the transmission of knowledge and for human cognitive development. It suffices to think of school education whereby a student listens to teachers reporting knowledge acquired, often indirectly, from the most varied sources such as text books, newspapers, personal memory, television, etc… Or let us consider the importance of oral tradition in the social and cultural development of civilisations. Or even (...) let us call to mind the learning process of infants who, only thanks to the knowledge learned from others, succeed in learning the language. Finally, with the emerging digital technology, the information gleaned from third parties is influencing the creation of knowledge in a full gamut of fields, in a quasi-comprehensive manner. This leads us to claim that hearsay, despite the reductionist conceptual scheme to which epistemology has confined it in that indirect testimony, is in any case quintessential in the dissemination of knowledge. This work fully expounds upon the basic mechanism of indirect testimonial transmission and provides an epistemologically founded explanation of the cognitive possibilities of hearsay by investigating, in the light of the anti-reductionist paradigm, three mutually connected epistemic properties, namely trust, reputation and coherence, that are key in the epistemic justification of the truth acquired via an indirect testimony.

Abstract It is sometimes thought that Absolute Idealism was undermined by its inability to deal with science. Through a critical discussion of F. H. Bradley's philosophy of science, this idea is challenged. His views on science are divided into a positive and a negative part, and it is argued that, although he found the scientific world view to be essentially false, he was nonetheless able to develop a sympathetic and intelligent philosophy of science. This was basically pragmatic and instrumental in (...) tone, and gave to science a large measure of autonomy from philosophy. His doctrine is connected with certain contemporary ideas in the philosophy of science. (shrink)

F. H. Bradley did not write extensively or systematically on the philosophy of religion, and much of what he did write has the character of either tentative speculation or the pre-emptive rebuttal of potential misinterpretations that might threaten his general philosophical position. ‘I admit that on this subject I never had much to say’ he warns. But such a remark should not discourage us from considering his views on this topic, since the disclaimer is typically Bradleian, and more reflective of (...) his high standards for what is required in order to claim to have something to say about some matter than of any genuine lack of opinion. On closer inspection we find that he has, scattered throughout his work, a great many important things to say about this subject. (shrink)

According to the truth-conduciveness problem of coherentism, the coherence theory of justification can hardly show that coherentist justification is truth-conducive. This problem is generally conceived as the most recalcitrant problem with the coherence theory. The purpose of this paper is to show that it does not pose a serious problem for a certain version of coherentism, namely a Sellarsian explanatory coherence theory of justification combined with the deflationary theory of truth. On this version of coherentism, our epistemic goal is to (...) gradually improve our conceptual framework so as to maximize its explanatory coherence, and there is no substantial norm of truth independent of the norms of justification, so that we cannot evaluate the truth-conduciveness of a belief independently of the norms of justification. I argue that this version of coherentism can cope with the truth-conduciveness problem. (shrink)

In this article, I argue that the relationship between place and self can be accounted for by recent theoretical work on autobiographical memory. The link between place and self is conceptualized as a transitory mental representation that emerges as a “place of mine” (personal autobiographical experience) from a “place” (declarative knowledge). The function of “place of mine” is to guide personal memory and self-knowing consciousness of periods of our lives. I combine inquiries of memory, self, and place in a triadic (...) relationship, a synthesis, suggesting a conceptual model for the phenomenon of place-related self as a sub-system of the self. This is formed by a causal progression from a physical place across time via emotional and cognitive bonds, components of the autobiographical information grounding the self, apportioned across declarative memory. Finally, using the methods of factor analysis and structural equation modeling, I show that the proposed model accounts for previous and new data on place-related identity. (shrink)

It is widely assumed that Russell's problems with the unity of the proposition were recurring and insoluble within the framework of the logical theory of his Principles of Mathematics. By contrast, Frege's functional analysis of thoughts (grounded in a type-theoretic distinction between concepts and objects) is commonly assumed to provide a solution to the problem or, at least, a means of avoiding the difficulty altogether. The Fregean solution is unavailable to Russell because of his commitment to the thesis that there (...) is only one ultimate ontological category. This, combined with Russell's reification of propositions, ensures that he must hold concepts and objects to be of the same logical and ontological type. In this paper I argue that, while Frege's treatment of the unity of the proposition has immediate advantages over Russell's, a deeper consideration of the philosophical underpinnings and metaphysical consequences of the two approaches reveals that Frege's supposed solution is, in fact, far from satisfactory. Russell's repudiation of the Fregean position in the Principles is, I contend, convincing and Russell's own position, despite its problems, conforms to a greater extent than Frege's with common sense and, furthermore, with certain ideas which are central to our understanding of the origins of the analytical tradition.

L’idéalisme britannique est un mouvement qui a dominé les universités britanniques pendant une cinquantaine d’années à la fin du xixe siècle et au début du xxe siècle, mais qui est passé presque totalement inaperçu dans le monde francophone. Rejetés en bloc par les philosophes analytiques, ces auteurs ont aussi été ignorés pendant longtemps dans leur pays, mais certains d’entre eux, notamment Bradley et Collingwood, jouissent d’un regain d’intérêt à la faveur d’un renouveau des études sur les origines de la philosophie (...) analytique. Ce texte est une introduction à l’idéalisme britannique, qui retrace, dans une première partie plus historique, les grandes lignes de sa genèse, son développement et son déclin. Dans une deuxième partie, nous donnons quelques arguments en faveur d’une étude plus approfondie de ce mouvement.British Idealism is a philosophical movement that dominated British universities , for fifty years around the turn from the XIXth to the XXth century, but it went largely unnoticed in the French-speaking world. Condemned by analytic philosophers, these authors were also ignored in their own country, but some of them, notably Bradley and Collingwood, are now enjoying a newly found popularity within the larger trend towards a study of the origins of analytic philosophy. This text is an introduction to British Idealism that plots, in an historical first part, the outlines of its rise, development and decline. In the second part, we provide reasons for further studies of this movement. (shrink)

Bradley thought that there is a connexion between the theory of reality and the theory of truth. The theory of reality to which he subscribed, Monism, rules out a correspondence theory of truth, he thought, since it denies the existence of a plurality of facts, or things, in virtue of correspondence to which a judgment could be true. But though he rejects the correspondence theory he insists on the independence of truth from belief, wish and hope. For him the test (...) of truth is coherence, which has two aspects, system and comprehensiveness. However, he does not think that this test yields ?absolute? truth. This, he maintains, for at least three different reasons, is unobtainable. Judgments can only be partially true. However, since there are degrees of truth, some judgments are closer to the truth than others, even though none are, or could be, unconditionally true. (shrink)

According to Epicureans, anticipating one's own annihilation ought not to be a frightening experience. Non-existence precludes the possibility of sensation, and hence annihilation can be neither pleasant nor unpleasant. And that which cannot be felt is unworthy of fear. Certain objectors to this claim have asserted that one's own annihilation really is a terrifying prospect. Against this assertion, I argue that those who make it are guilty of precisely the kind of confusion that Epicurus and his disciples alert us to, (...) namely that of projecting ourselves into the thought of our own non-existence. A further objection to Epicureanism involves the claim that, since the fear of death is merely the converse of the love of life, the one cannot be extinguished without inevitably extinguishing the other (to inevitably disastrous effect). I argue that this objection relies upon an exaggeration of thanatological fear's power and an unduly pessimistic assessment of human reason's capacity to positively modify emotional states and dispositions. I conclude that neither of the objections considered here has vindicated the fear and anxiety commonly associated with anticipating one's annihilation, and that the Epicurean attempt to deflate these debilitating emotions remains valid.

Immediate knowledge is here construed as true belief that does not owe its status as knowledge to support by other knowledge (or justified belief) of the same subject. The bulk of the paper is devoted to a criticism of attempts to show the impossibility of immediate knowledge. I concentrate on attempts by Wilfrid Sellars and Laurence Bonjour to show that putative immediate knowledge really depends on higher-level knowledge or justified belief about the status of the beliefs involved in the putative (...) immediate knowledge. It is concluded that their arguments are lacking in cogency. (shrink)
