In this paper, I lend novel support to H. P. Grice’s account of speaker meaning (GASM) by blunting the force of a significant objection. Stephen Schiffer has argued that in order to make GASM sufficient, one must add restrictions that are psychologically impossible to fulfill, thereby making GASM untenable. In what follows, I explain the elements of GASM that require it to invoke these psychologically unrealizable restrictions. I then accept Schiffer’s criticism, but modify its significance to GASM. I argue that (...) the problem that Schiffer notes is not a reason to reject GASM, but a reason to embrace it. GASM shows that meaning is best understood as an absolute concept—an unrealizable ideal limit. Taking some inspiration from contextualist theories of knowledge attribution, I argue that my version of GASM offers a useful contextualist account of meaning attribution. Hence, pragmatic theories of meaning and communication should not wholly exclude GASM from their theorizing, at least not for the reasons that are commonly given. (shrink)

Daniel Kolak’s theory of synchronic consciousness according to which the entire range of dissociative phenomena, from pathologies such as MPD and schizophrenia to normal dream states, are best explained in terms of consciousness becoming simultaneously identified as many selves, has revolutionary therapeutic implications for neurology and psychiatry. All these selves, according to Kolak—even the purely imaginary ones that exist as such only in our dreams—are not just conscious but also self-conscious, with beliefs, intentions, living lives informed by memories (confabulatory, (...) in the case of the fictional ones) and personal histories. Kolak’s derivation of psychiatrically relevant aspects of his theory—a neurological rendition of a Kantian transcendental argument—can be given a straightforward neurological, and therefore open to scientific scrutiny, interpretation that would then more easily lend itself to the clinical setting in which these perplexing phenomena, along with their purveyors, must live and cope. This will be the main focus of this paper. (shrink)

H. B. Smith, Professor of Philosophy at the influential Pennsylvania School was (roughly) a contemporary of C. I. Lewis who was similarly interested in a proper account of implication. His research also led him into the study of modal logic but in a different direction than Lewis was led. His account of modal logic does not lend itself as readily as Lewis' to the received possible worlds semantics, so that the Smith approach was a casualty rather than a (...) beneficiary of the renewed interest in modality. In this essay we present some of the main points of the Smith approach, in a new guise. (shrink)

Evidence that confirms a scientific hypothesis is said to be ‘novel’ if it is not discovered until after the hypothesis isconstructed. The philosophical issues surrounding novel confirmation have been well summarized by Campbell and Vinci [1983]. They write that philosophers of science generally agree that when observational evidence supports a theory, the confirmation is much stronger when the evidence is ‘novel’. . . There are, nevertheless, reasons to be skeptical of this tradition . . . The notion of novel confirmation (...) is beset with a theoretical puzzle about how the degree of confirmation can change without any change in the evidence, hypothesis, or auxiliary assumptions . . . There have not yet appeared any obviously satisfactory solutions to these problems Much of the literature on novel confirmation relies on the Bayesian analysis of conditional probabilities. Let H represent a hypothesis, E an event that confirms the hypothesis, and B some relevant background information. Denote by Pr(x | y) the conditional probability of x given y. There are various plausible measures of the degree of support that E lends to H. Among these are: Degree of support = Pr(H|E) Degree of support = Pr(H|E & B) – Pr(H|B) Degree of support = Pr(H|B & B) – Pr(H|B – {E}) Degree of support = Pr(H|B & knowledge that H E) – Pt(H|B) In the work cited, Campbell and Vinci offer a somewhat more involved Bayesian interpretation. Formula (1) is discussed by Gardner [1981] who points out that under this formulation there can be no role for novelty. 'The function Pr(H|E) contains no third slot in which to insert a temporal relation between the invention of H and the inventor's learning E. Obviously, then, this relation could not possibly affect E's support of H.' Formula (2), on the other hand, suggests a role for novelty. Bayes's Theorem allows us to rewrite the formula as (2') Degree of support = Pr(H|B) x [Pr(E|H&B) – 1] We can use 1/Pr(E|B) as a measure of the novelty of E. Then (2') shows that the degree of support increases with novelty of E. In the paper already cited, Campbell and Vinci discuss shortcomings of this analysis. Formula (3) expresses an alternative offered by Howson [1984]. In that formula, Pr(H/B – {E}) represents the probability of H assuming (counterfactually) that only B – {E} is known. This allows for the possibility of non-novel facts generating support for hypotheses. Niiniluoto [1984] argues for a variant along the lines of (4), in which we account for the possibility that the theorist was unaware that his hypothesis entails E. One problem in deciding among these approaches is that the choice of a definition for the degree of support appears arbitrary. What kind of argument could justify the choice of one definition over another? It is our position that there can be no basis for addressing this question in the absence of an explicit model of the process by which hypotheses are generated. Only in the presence of such a model can the various conditional probabilities be given meaningful interpretations. We provide such models in Sections 1, 2 and 4. The simple model of Section 1, incorporating strong assumptions, yields the conclusion that novelty is irrelevant. When these assumptions are relaxed in the later sections, novelty becomes relevant for a variety of reasons. It is at least potentially the case that scientists have more information about their own abilities than is publicly available, and this information might influence their decisions about whether even to attempt novel prediction. If this is so, then it should be incorporated into the model of hypothesis generation. This requires an explicit discussion of how scientists respond to incentives and how the incentives themselves evolve, which in turn takes us into the realm of economic theory. We have addressed these issues in another paper, written for an audience of economists. The results of this research are summarized in Section 3. (shrink)

Algebraic/topological descriptions of living processes are indispensable to the understanding of both biological and cognitive functions. This paper presents a fundamental algebraic description of living/cognitive processes and exposes its inherent ambiguity. Since ambiguity is forbidden to computation, no computational description can lend insight to inherently ambiguous processes. The impredicativity of these models is not a flaw, but is, rather, their strength. It enables us to reason with ambiguous mathematical representations of ambiguous natural processes. The noncomputability of these structures means computerized (...) simulacra of them are uninformative of their key properties. This leads to the question of how we should reason about them. That question is answered in this paper by presenting an example of such reasoning, the demonstration of a topological strategy for understanding how the fundamental structure can form itself from within itself.

This paper pursues the question, To what extent does the propensity approach to probability contribute to plausible solutions to various anomalies which occur in quantum mechanics? The position I shall defend is that of the three interpretations — the frequency, the subjective, and the propensity — only the third accommodates the possibility, in principle, of providing a realistic interpretation of ontic indeterminism. If these considerations are correct, then they lend support to Popper's contention that the propensity construction tends to remove (...) (at least some of) the mystery from quantum phenomena.

Oleg Grabar has argued that there was not a system of visual symbols in Islamic culture; consequently it is difflcult to hold that an Islamic architecture exists; that is, if we were to stand before a mosque and try to experience it aesthetically or see what kind of building it is we would not be able to say that it is a mosque. In this paper we argue against this proposition. We, first, present a brief analysis of Grabar's view. Second, (...) we critically evaluate this view. Third, we explicate how the mosque as an architectural type embodies uniquely Islamic symbols. We shall illustrate this point by an analysis of one basic Islamic symbol: the Mihrab. The thesis we defend is that there are basic Islamic symbols and that these symbols inhere in the mosque. It is this fact that lends credibility to the claim that an Islamic architecture exists. /// Oleg Grabar defendeu a tese de que não existe um sistema de símbolos visuais na cultura islâmica; consequentemente, é difícil defender a existência de uma arquitectura islâmica; ou seja, se estivéssemos diante de uma mesquita e tentássemos fazer uma experiência estética da mesma ou analisar que tipo de edifício se trata, não seríamos capazes de dizer que se trata de uma mesquita. No presente artigo, os autores argumentam contra esta proposição. Em primeiro lugar, os autores começam por apresentar uma breve análise do ponto de vista de Grabar. Em segundo lugar, avaliam criticamente esta posição. Em terceiro lugar tentam explicar até que ponto a mesquita como tipo arquitectónico apenas incorpora símbolos islâmicos. Os autores exemplificam este ponto mediante a análise de um dos símbolos básicos do Islamismo: o Mihrab. O artigo defende, portanto, a tese de que existem símbolos islâmicos básicos e de que estes símbolos estão presentes na mesquita. Ora é precisamente este facto que dá credibilidade à afirmação de que existe uma arquitectura islâmica propriamente dita. (shrink)

Stigmata, wounds resembling those of Christ, have been reported since the 13th century. The wounds typically appear in association with visions following prolonged fasting. This paper argues that self-starvation holds the key to understanding this unique event. Stigmata may result from self-mutilation occurring during dissociation, phenomena precipitated in part by dietary constriction. Psychophysiological mechanisms produced by natural selection adjust the salience of risk in light of current resource abundance. As a result, artificial dietary constriction results in indifference to harm. A (...) variety of data links dramatic dietary constriction, reduced serotonergic functioning, altered states of consciousness, and self-injurious behavior. Catholic representations of Christ's crucifixion provide a cultural context that both motivates and lends meaning to the experiences of individuals whose predispositions and life histories increase the likelihood of dietary constriction, dissociation, and self-mutilation. Examining this case raises interesting questions about both the evolutionary and the cultural grounds for defining individual psychopathology. (shrink)

There exists in the United States a popular account of the historical roots of environmental philosophy which is worth noting not simply as a matter of historical interest, but also as a source book for some of the key ideas that lend shape to contemporary North American environmental philosophy. However, this folk wisdom about the historical beginnings of North American environmental thinking is incomplete. The wilderness-based history commonly used by environmental philosophers should be supplemented with the neglected story of garbage (...) and sanitation in North American urban areas during the nineteenth century. This supplemented history changes the conceptual territory over which North American environmental philosophy roams. This new territory is better suited to a number of important local and international environmental challenges. (shrink)

Third World countries should exploit the genetic information stored in their flora and fauna to develop independent and highly competitive biotechnological and pharmaceutical industries. The necessary condition for this policy to succeed is the reshaping of their universities and hospitals—to turn them into high-caliber research institutions dedicated to the creation of original knowledge and biomedical invention. Part of the service of the Third World foreign debt should be co-invested with the lending banks in high technology enterprises. This should be complemented (...) with an active program of investments in First World biotech companies and university research departments which could contribute to the solving of problems connected with the First World. These strategic alliances would allow effective training of molecular biologists, improvement of South American universities, and education of biotechnologists, managers, and lawyers in the complexities of high-technology business. The establishment of real joint ventures between developed and underdeveloped countries might contribute to change the present strained relations between the North and the South, and science and technology could become real forces of social and economic development.
