Francis Bacon’s theory of matter is a controversial topic among historians. I agree with the viewpoint, which suggests that although Bacon changed his views on atomism repeatedly, he never rejected it completely (Partington, Urbach, Gemelli). I will substantiate this interpretation by paying more attention to the usually neglected allegorical works and by investigating why Bacon changed his mind on atomism in his Novum organum. I shall reconstruct Bacon’s various opinions in chronological order to establish his final evaluation of atomism and (...) his reasons for it. Given that Bacon never embraced a matter theory identical with Greek atomism, I shall here define atomism in the broadest sense, as a corpuscular matter theory that posits final and indivisible particles. Following this semantic delimitation, two successive Baconian opinions will be distinguished: the first took the atom to constitute an ontological and causative-operational principle; the second deprived the atom of this causative-operational ability, but did not touch its ontological priority. At the same time, I will investigate the question concerning the coexistence of atomism and pneumatism in Bacon’s theory, a point that has been discussed in the influential interpretations by Kargon and Rees. I shall argue that Bacon did not regard these two doctrines as incompatible. (shrink)

The notion of space is one of the most discussed within classical physics concepts. The works of Copernicus and Galileo, as well as Gassendi´s ideas led to Newton to regard it as substance. This conception of space, allows the notion of symmetry is present in an indirect or implied, within the laws of physics, formed through the notions of equivalence and balance. The aim of this study is to identify the symmetry, through such notions, under the study of indistinction between (...) the repose state and the state of uniform translational movement known as the law of inertia. The philosophical approach is framed in the link between these notions and the problem of indistinguishability between states of different movement. We will discuss first the conception of space Telesio and Gassendi that led Newton to his absolutist conception of space. The conception of space and its relationship with Newton symmetry is the second part of our work. As a third part present linking of the Newtonian space with notions of balance, symmetry and equivalence. Subsequently they give our conclusions. (shrink)

La noción de espacio representa una de las concepciones más discutidas dentro de la física clásica. Los trabajos de Copérnico y Galileo, así como las ideas de Gassendi, condujeron a Newton a considerarlo como sustancia. Esta concepción del espacio, permite que la noción de simetría se presente de una forma indirecta o implícita, dentro de las leyes de la física, a través de las nociones de equivalencia y equilibrio. El objetivo de este trabajo es la de identificar la simetría, a (...) través de dichas nociones, bajo el estudio de la indistinción entre el estado de reposo y el estado de movimiento de traslación uniforme conocido como ley de inercia. El enfoque filosófico está enmarcado en la vinculación entre estas nociones y el problema de la indiscernibilidad entre estados de movimiento diferentes. Expondremos primeramente, la concepción de espacio de Telesio y Gassendi que llevaron a Newton a su concepción absolutista del mismo. La concepción de espacio de Newton y su relación con la simetría es la segunda parte de nuestro trabajo. Como tercera parte presentamos la vinculación de dicho espacio newtoniano con las nociones de equilibrio, equivalencia y simetría. Posteriormente se dan nuestras conclusiones. (shrink)
