    Computation in Physical Systems: A Normative Mapping Account

    Get PDF
    The relationship between abstract formal procedures and the activities of actual physical systems has proved to be surprisingly subtle and controversial, and there are a number of competing accounts of when a physical system can be properly said to implement a mathematical formalism and hence perform a computation. I defend an account wherein computational descriptions of physical systems are high-level normative interpretations motivated by our pragmatic concerns. Furthermore, the criteria of utility and success vary according to our diverse purposes and pragmatic goals. Hence there is no independent or uniform fact to the matter, and I advance the ‘anti-realist’ conclusion that computational descriptions of physical systems are not founded upon deep ontological distinctions, but rather upon interest-relative human conventions. Hence physical computation is a ‘conventional’ rather than a ‘natural’ kind

    The Structure of Sensorimotor Explanation

    The sensorimotor theory of vision and visual consciousness is often described as a radical alternative to the computational and connectionist orthodoxy in the study of visual perception. However, it is far from clear whether the theory represents a significant departure from orthodox approaches or whether it is an enrichment of it. In this study, I tackle this issue by focusing on the explanatory structure of the sensorimotor theory. I argue that the standard formulation of the theory subscribes to the same theses of the dynamical hypothesis and that it affords covering-law explanations. This however exposes the theory to the mere description worry and generates a puzzle about the role of representations. I then argue that the sensorimotor theory is compatible with a mechanistic framework, and show how this can overcome the mere description worry and solve the problem of the explanatory role of representations. By doing so, it will be shown that the theory should be understood as an enrichment of the orthodoxy, rather than an alternative

    Social theory and the analysis of transactions

    Este artículo analiza una seria objeción a las teorías sociales que apoyan los mecanismos apagados y las fuerzas escondidas que, a su vez, influyen en los actores sociales: ellas destacan la necesidad teórica de confirmar sus presuposiciones tanto si ellas son demostradas como si son desmentidas por los fenómenos en los que ellas mismas se centran. En primer lugar, el autor examina cómo Latour ha puesto en evidencia decididamente este problema. Se trata, pues, de uno de los objetivos polémicos principales de Latour, la teoría social de Bourdieu, para demostrar que, en realidad, Bourdieu compartió las preocupaciones de Latour. Este artículo lleva a cabo este objetivo deteniéndose en la relación entre la noción de rule-following de Wittgenstein y la de habitus de Bourdieu. En la base de este análisis, el autor profundiza el concepto de transactions, que atañe a las interpretaciones discursivas de los actores y al contexto semiótico en los que se insertan. Este análisis finaliza con las consecuencias teóricopolíticas de este tipo de metodología.This article discusses a serious objection to social theories that claim opaque mechanisms and hidden forces operate over social actors’ head: they bespeak the theorists’ need to confirm their presuppositions whether they are proven or disproven by the phenomena they focus on. The author first explores the way in which Latour has convincingly unearthed this problem. He then analyzes one of Latour’s primary polemical targets, Bourdieu’s social theory, to show that in reality Bourdieu shared Latour’s concerns. The article does so by exploring the nexus between Wittgenstein’s notion of rule-following and notion of Bourdieu’s habitus. Based on this analysis, the author elaborates on the concept of “transactions”, which draws attention to both the actors’ discursive performances and the semiotic context where they take place. The article concludes by illustrating the theoretical-political consequences of this methodological commitment

    Studying cities to learn about minds: some possible implications of space syntax for spatial cognition

    Get PDF
    What can we learn of the human mind by examining its products? The city is a case in point. Since the beginning of cities human ideas about them have been dominated by geometric ideas, and the real history of cities has always oscillated between the geometric and the ‘organic’. Set in the context of the suggestion from cognitive neuroscience that we impose more geometric order on the world than it actually possesses, and intriguing question arises: what is the role of the geometric intuition in how we understand cities and how we create them? Here I argue, drawing on space syntax research which has sought to link the detailed spatial morphology of cities to observable functional regularities, that all cities, the organic as well as the geometric, are pervasively ordered by geometric intuition, so that neither the forms of the cities nor their functioning can be understood without insight into their distinctive and pervasive emergent geometrical forms. The city is often said to be the creation of economic and social processes, but here it is argued that these processes operate within an envelope of geometric possibility defined by the human mind in its interaction with spatial laws that govern the relations between objects and spaces in the ambient world

    ECONOMETRICS AND REALITY

    Get PDF
    Starting with a realist ontology the economic methodologist, Tony Lawson, argues that econometrics is a failed project. Apparently more sympathetic to econometrics, the philosopher of science, Nancy Cartwright, again from a realist perspective, nonetheless argues for conditions of applicability that are so stringent that she must seriously doubt the usefulness of econometrics. In this paper, I reconsider Lawson''s and Cartwright''s analyses and argue that realism supports rather than undermines econometrics properly interpreted and executed.
