We call for a new philosophical conception of models in physics. Some standard conceptions take models to be useful approximations to theorems, that are the chief means to test theories. Hence the heuristics of model building is dictated by the requirements and practice of theory-testing. In this paper we argue that a theory-driven view of models can not account for common procedures used by scientists to model phenomena. We illustrate this thesis with a case study: the construction of one of (...) the first comprehensive model of superconductivity by London brothers in 1934. Instead of theory-driven view of models, we suggest a phenomenologically-driven one. (shrink)

Some cognitive states — e.g. states of thinking, calculating, navigating — may be partially external because, at least sometimes, these states depend on the use of symbols and artifacts that are outside the body. Maps, signs, writing implements may sometimes be as inextricably bound up with the workings of cognition as neural structures or internally realized symbols (if there are any). According to what Clark and Chalmers [1998] call active externalism, the environment can drive and so partially constitute cognitive processes. (...) Where does the mind stop and the rest of the world begin? If active externalism is right, then the boundary cannot be drawn at the skull. The mind reaches – or at least can reach --- beyond the limits of the body out into the world. (shrink)

Our aim in this paper is to throw some light on the kind of normativity characteristic of human knowledge. We describe the epistemic normative domain as that field of human agency defined by knowledge understood as an achievement. The normativity of knowledge rests on the contribution of the epistemic agent to the fulfillment of certain tasks. Such contribution is epistemically significant when the agent becomes engaged in the obtaining of success. Finally, we identify some features associated with full epistemic agency (...) and elucidate what we mean by engagement by appealing to the idea of adopting an epistemic perspective. En este artículo pretendemos arrojar luz sobre la normatividad propia del conocimiento humano. Describimos el dominio normativo epistémico como un campo de agencia humana que está definido por el conocimiento entendido como logro. La normatividad del conocimiento se apoya en la contribución del agente epistémico a la consecución de ciertas tareas. Tal contribución es epistémicamente significativa cuando el agente llega a participar en la consecución del éxito. Por último identificamos algunos rasgos asociados con la agencia epistémica completa, y aclaramos lo que queremos decir con implicación apelando a la idea de adoptar una perspectiva epistémica.
