In this paper, I discuss Spinoza on the proper methods and content of physical science. I start by showing how Spinoza's epistemology leads him to a kind of pessimism about the prospects of empirical and mathematical methods in natural philosophy. While they are useful for life, they do not tell us about nature, as Spinoza puts it, “as it is in itself.” At the same time, Spinoza seems to allow that we have some knowledge of physical things and their behavior. (...) So I go on to outline and critique a few of the accounts of how Spinoza thinks we can do this, focusing on the role of the common notions in physics. In the third section, I discuss the possible contents of physics, for Spinoza, and argue that they are not, as is usually thought, fundamentally Cartesian. I conclude by pointing to some promising directions for future research and suggesting a few heuristics for such research. (shrink)

Spinoza developed a highly interesting metaphysical theory of nature and individuality. In this paper, I endeavor to bring forward some ideas on how Spinozistic views on extended substance, physical world, and individuality can be approached using the concept of power as the basis of interpretation. Jonathan Bennett's ‘field metaphysical’ interpretation of Spinoza's doctrine of one extended substance has generated much discussion, and forms the other starting point of my paper. I believe that the field metaphysical interpretation enables one to deal (...) with the central questions concerning physical individuation — individuality and the persistence of individual being — in a rather novel way. My main question is this: what follows if physical individuals are seen as parts of a unified field of extended power? (shrink)

The aim of this paper is to contribute to a more balanced judgement than the widespread impression that the changes which are called for in today's philosophy of physics and which centre around the concept of holism amount to a rupture with the framework of Cartesian philosophy of physics. I argue that this framework includes a sort of holism: As a result of the identification of matter with space, any physical property can be instantiated only if there is the whole (...) of matter. Relating this holism to general relativity, I maintain that this holism cannot be directly applied to today's philosophy of physics consequent upon the failure of geometrodynamics. I show in what respect precisely the holism in quantum physics amounts to a revision of the holism within Cartesianism. (shrink)

Na carta 12 de sua correspondência, Spinoza expõe sua con-cepção do infinito atual. Nesse contexto, ele desenvolve certos aspectos de sua ontologia de imanência, assim como o significado que para ele possuem os conceitos de eternidade, duração e tempo. Este texto tor-na-se então central para qualquer estudioso da questão da temporalidade em Spinoza. Nosso autor distancia-se da perspectiva cartesiana que, na mesma questão, expôs —não sem críticas— nos Princípios da Filosofia Cartesiana e nos Pensamentos Metafísicos, ambos publicados em 1663. Neste (...) artigo nos propomos estudar a distinção entre duração e tempo, para sublinhar a perspectiva propriamente spinozista da carta 12, e assim mostrar o significado que para Spinoza esses conceitos possuem no con-texto de uma discussão científica sobre o infinito atual.
