RésuméMoore attribuah l'idéalisme de Berkeley à sa négligence de la distinction entre l'acte d'appréhension et son objet. Bien que Berkeley ait justement tracé cette distinction dans le premier Dialogue, et l'ait rejetée, peu s'en sont aperçu, et ceux qui l'ont remarqué lui reprochent habituellement de confondre l'acte d'appréhension avec une action. La thèse ici développée est que Berkeley n'est pas coupable de cette confusion et qu'il rejette la distinction, en fait, pour de bonnes raisons à caractére empiriste, qui ont à (...) voir avec ce que l'on tient pour son argument principal.

A representation is a remnant of previous experience that allows that experience to affect later behavior. This paper develops a metatheoretical view of representation and applies it to issues concerning representation in animals. To describe a representational system one must specify the following: thedomainor range of situations in the represented world to which the system applies; thecontentor set of features encoded and preserved by the system; thecodeor transformational rules relating features of the representation to the corresponding features of the represented (...) world; themedium, or the representation's physical instantiation; and thedynamics, or how the system changes with time. In part because of the behaviorist assumption that the hypothetical, covert changes occurring in an organism during learning correspond to the overt physical changes that are observed, issues of representation in animal behavior have been largely ignored as irrelevant or misleading. However, it can be inferred that representations, acting as models of environmental regularities, operate at many levels of behavioral functioning, both cognitive and noncognitive. Objections to the use of this concept in explanations of animal behavior, based on the claim that it is indeterminate and on behaviorist considerations of parsimony, can be answered. Animal representations may be specialized in terms of tasks and species. Data from tasks involving spatial memory, delayed matching-to-sample, and sequence learning suggest some foundations for a general theory of animal representations. (shrink)

ArgumentThis paper argues that Samuel Clarke's account of agent causation (i) provides a philosophical basis for moderate voluntarism, and (ii) both leads to and benefits from the acceptance of partial occasionalism as a model of causation for material beings. Clarke's account of agent causation entails that for an agent to be properly called an agent (i.e. causally efficacious), it is essential that the agent is free to choose whether to act or not. This freedom is compatible with the existence of (...) conceptually necessary connections. Hence, Clarke can harmonize God's freedom of choosing with the existence of eternal and necessary relations among things. Moreover, in Clarke's account, only intelligent entities can be properly understood as efficacious causes. Beings deprived of intelligence are not agents or efficacious causes at all and their effects are thus the result of the immediate action of some intelligent being operating upon them. (shrink)

Abstract According to idealism the world, as we perceive it, is in effect a creation of the mind. There are many different forms of idealism and this paper investigates one form of idealism that was advocated by the 4th century Buddhist Yog?c?rin Vasubandhu and one not unfamiliar in the west, especially in the works of George Berkeley. This paper suggests that when idealism, as a metaphysical theory, is set within a soteriological framework, as is the case with Vasubandhu, it serves (...) to bridge the philosophical endeavour with the religious quest as outlined in Buddhist thought. Idealism is a theory about the borders between mind and matter, and specifically about the demolition of matter. This demolition, in the hands of Vasubandhu, manages to redefine the framework of speculation by incorporating the soteriological within it and thus constructing a viable bridge between philosophy and religion.

Intentionalism is the view that the phenomenal character of a conscious experience is wholly determined by, or even reducible to, its representational content. In this essay I put forward a version of intentionalism that allows (though does not require) the reduction of phenomenal character to representational content. Unlike other reductionist theories, however, it does not require the acceptance of phenomenal externalism (the view that phenomenal character does not supervene on the internal state of the subject). According the view offered here, (...) phenomenal characters essentially represent subject-environment relations that are relevant to the possibilities for causal interaction between the subject and the environment; relations of the kind that J. J. Gibson dubbed affordances. I argue for this view chiefly through an examination of spatial perception, though other cases are also considered. The view assumes that a phenomenal character has an essential functional role; though it need not be assumed that a functional role is sufficient for a phenomenal character. (shrink)

Mach's principle is discussed as a fundamental statement on kinematics, and an apparent contradiction is identified in the Lorentz-Minkowski form of the inertial metric. To resolve the incompatibility, length is redefined so that the speed of light is a field-dependent variable, although still constant for all inertial observers at a point in space-time. Gravitational theories with variableG are considered, and it is shown that a redefinition of length and time results in constantG and variablec.

I develop a non-representationalist account of mathematical thought, on which the point of mathematical theorizing is to provide us with the conceptual capacity to structure and articulate information about the physical world in an epistemically useful way. On my view, accepting a mathematical theory is not a matter of having a belief about some subject matter; it is rather a matter of structuring logical space, in a sense to be made precise. This provides an elegant account of the cognitive utility (...) of mathematics. Further, it makes explicit how the brand of non-representationalism I develop is compatible with there being substantive rationality constraints on our mathematical theorizing. (shrink)

The perceptual logic of j hintikka and r thomason is imbedded in a more general framework of quantification over individual-concepts. two intensional predicates for physical individuation and perceptual individuation are required in place of thomason's two variable-sorts. objectual perception of x by s is then definable as "for some y there is a perceptually individuated object z, in fact identical with x, such that s perceives that y is z.".

Hilbert’s choice operators τ and ε, when added to intuitionistic logic, strengthen it. In the presence of certain extensionality axioms they produce classical logic, while in the presence of weaker decidability conditions for terms they produce various superintuitionistic intermediate logics. In this thesis, I argue that there are important philosophical lessons to be learned from these results. To make the case, I begin with a historical discussion situating the development of Hilbert’s operators in relation to his evolving program in the (...) foundations of mathematics and in relation to philosophical motivations leading to the development of intuitionistic logic. This sets the stage for a brief description of the relevant part of Dummett’s program to recast debates in metaphysics, and in particular disputes about realism and anti-realism, as closely intertwined with issues in philosophical logic, with the acceptance of classical logic for a domain reflecting a commitment to realism for that domain. Then I review extant results about what is provable and what is not when one adds epsilon to intuitionistic logic, largely due to Bell and DeVidi, and I give several new proofs of intermediate logics from intuitionistic logic+ε without identity. With all this in hand, I turn to a discussion of the philosophical significance of choice operators. Among the conclusions I defend are that these results provide a finer-grained basis for Dummett’s contention that commitment to classically valid but intuitionistically invalid principles reflect metaphysical commitments by showing those principles to be derivable from certain existence assumptions; that Dummett’s framework is improved by these results as they show that questions of realism and anti-realism are not an “all or nothing” matter, but that there are plausibly metaphysical stances between the poles of anti-realism and realism, because different sorts of ontological assumptions yield intermediate rather than classical logic; and that these intermediate positions between classical and intuitionistic logic link up in interesting ways with our intuitions about issues of objectivity and reality, and do so usefully by linking to questions around intriguing everyday concepts such as “is smart,” which I suggest involve a number of distinct dimensions which might themselves be objective, but because of their multivalent structure are themselves intermediate between being objective and not. Finally, I discuss the implications of these results for ongoing debates about the status of arbitrary and ideal objects in the foundations of logic, showing among other things that much of the discussion is flawed because it does not recognize the degree to which the claims being made depend on the presumption that one is working with a very strong logic.

El objetivo del presente artículo es ofrecer una interpretación de la doctrina del esquematismo de los conceptos empíricos y matemáticos presentada por Kant en su Crítica de la razón pura. Mostramos que los esquemas de los conceptos empíricos y matemáticos son procedimientos de síntesis gobernados por reglas conceptuales. Aunque no consideramos que esta doctrina kantiana carece de problemas, nuestro trabajo muestra que: 1) esos esquemas pueden distinguirse rigurosamente de sus correspondientes conceptos; 2) esos esquemas no son entidades superfluas. Estas conclusiones (...) se alcanzan mostrando que el contenido de un concepto determina la unidad de elementos sensibles que tiene que ser efectuada por un esquema en tanto procedimiento de síntesis.
