The aim of the paper is to show that topoi are useful in the categorial analysis of the constructive logic with strong negation. In any topos ϵ we can distinguish an object Λ and its truth-arrows such that sets ϵ have a Nelson algebra structure. The object Λ is defined by the categorial counterpart of the algebraic FIDEL-VAKARELOV construction. Then it is possible to define the universal quantifier morphism which permits us to make the first order predicate calculus. The completeness (...) theorem is proved using the Kripke-type semantic defined by THOMASON. (shrink)

The major contributions of operationism have been negative, largely because operationists failed to distinguish logical theories of reference from empirical accounts of language. Behaviorism never finished an adequate formulation of verbal reports and therefore could not convincingly embrace subjective terms. But verbal responses to private stimuli can arise as social products through the contingencies of reinforcement arranged by verbal communities.

Human adults possess the extraordinary ability to produce mental imagery about a wide variety of non-occurrent events. We can, for example, simulate the perception of different places, different times, different possibilities, or others’ perspectives. Findings from cognitive psychology, neuropsychology, and cognitive neuroscience suggest that all of these capacities rely on the same neuro-cognitive mechanism: episodic simulation. This ability produces mental imagery by constructively recombining elements of past experiences to simulate event representations. However, if episodic simulation indeed produces mental imagery, it (...) remains unclear how the non-imagistic aspects of its outputs become cognitively determined. In this article, I argue that there are (at least) four such non-imagistic ‘dimensions’ of episodic simulation: specificity, temporal orientation, subjectivity, and factuality. Further, I propose an account of the mechanisms which might be responsible for determining where a given output of episodic simulation falls within this dimensional space. According to this view, episodic simulation relies on propositional ‘scope-operators’ either deployed as inputs to the simulation process itself or produced by post-hoc monitoring processes operating over its outputs. This view has consequences for how we should view the operation, development, and evolution of episodic simulation. (shrink)

_The VaKE Handbook: Theory and Practice of Values and Knowledge Education_ presents a theoretical model and many examples in various fields of education and training for the realization of the principle "Values without knowledge are blind, while knowledge without values is irresponsible".

Daniel Dennett is arguably one of the most influential yet radical philosophers in America today. In this volume, Dennett is confronted by colleagues and critics, from philosophy, biology and psychology. His reply constitutes an extensive essay which clarifies, and develops further, central themes in his philosophy. The debate ranges over Dennett's whole corpus, but special attention is given to his major work on consciousness, Consciousness Explained. The volume includes a critical assessement of Dennett's views on behaviouralism and the subjectivity of (...) consciousness, the nature of perception and mental representation, intentional laws and computational psychology, the rationality of thought, culture as a virus, the architecture of mind, and the role of artifacts in thinking. Also included is an introduction to Dennett's philosophy and a full bibliography of his publications. (shrink)

The present author developed a calculus for the logic of ‘because’. In a recent paper in this journal, it has been claimed that the central inference rules for the logic are invalid and that the intuition upon which the rules are based is not accounted for. This note criticises these arguments and presents an independent argument in favour of the rules used in the logic.

The main result of this paper is Theorem 3.1 which is a criterion for weak o-minimality of a linearly ordered structure in terms of realizations of 1-types. Here we also prove some other properties of weakly o-minimal structures. In particular, we characterize all weakly o-minimal linear orderings in the signature $\{ . Moreover, we present a criterion for density of isolated types of a weakly o-minimal theory. Lastly, at the end of the paper we present some remarks on the Exchange (...) Principle for algebraic closure in a weakly o-minimal structure. (shrink)

There is currently a debate over whether cognitive architecture is classical or connectionist in nature. One finds the following three comparisons between classical architecture and connectionist architecture made in the pro-connectionist literature in this debate: (1) connectionist architecture is neurally plausible and classical architecture is not; (2) connectionist architecture is far better suited to model pattern recognition capacities than is classical architecture; and (3) connectionist architecture is far better suited to model the acquisition of pattern recognition capacities by learning than (...) is classical architecture. If true, (1)-(3) would yield a compelling case against the view that cognitive architecture is classical, and would offer some reason to think that cognitive architecture may be connectionist. We first present the case for (1)-(3) in the very words of connectionist enthusiasts. We then argue that the currently available evidence fails to support any of (1)-(3). (shrink)

This essay focuses on the theme of intersubjectivity, which is central to the entire Indo-Tibetan Buddhist tradition. It addresses the following five themes pertaining to Buddhist concepts of intersubjectivity: the Buddhist practice of the cultivation of meditative quiescence challenges the hypothesis that individual human consciousness emerges solely from the dynamic interrelation of self and other; the central Buddhist insight practice of the four applications of mindfulness is a means for gaining insight into the nature of oneself, others and the relation (...) between oneself and the rest of the world, which provides a basis for cultivating a deep sense of empathy; the Buddhist cultivation of the four immeasurables is expressly designed to arouse a rich sense of empathy with others; the meditative practice of dream yoga, which illuminates the dream-like nature of waking reality is shown to have deep implications regarding the nature of intersubjectivity; the theory and practice of Dzogchen, the 'great perfection' system of meditation, challenges the assertion of the existence of an inherently real, localized, ego-centred mind, as well as the dichotomy of objective space as opposed to perceptual space.

The Alligator's Child was full of 'satiable curtiosity. One day while rummaging in a trunk in the lumber room he came across a photograph of his father wearing an aardvark uniform and standing by a large ant hill. All excitement, he rushed to his father and breathlessly said, ‘Father, I didn't know that you had been an aardvark! What is it like to be an aardvark?’.
