This paper offers a reconstruction of the interpretations of Descartes's ideas of place and motion by Dutch Cartesians (Henricus Regius, Johannes de Raey, Johannes Clauberg, and Christoph Wittich). It does so by focusing on the reading of Descartes's Principia philosophiae (1644) offered, in particular, by the dictated commentaries on it. It is shown how such commentaries bring to the light new potential Aristotelian-Scholastic sources of Descartes, and the different ways Dutch Cartesians brought to the fore, also with the help of (...) such sources, the rationale of the Cartesian text: in doing so, they constituted a philosophical school.

Utilizing Einstein’s comparison of General Relativity and Descartes’ physics, this investigation explores the alleged conventionalism that pervades the ontology of substantival and relationist conceptions of spacetime. Although previously discussed, namely by Rynasiewicz and Hoefer, it will be argued that the close similarities between General Relativity and Cartesian physics have not been adequately treated in the literature—and that the disclosure of these similarities bolsters the case for a conventionalist interpretation of spacetime ontology.

This paper explores various metaphysical aspects of Leibniz’s concepts of space, motion, and matter, with the intention of demonstrating how the distinctive role of force in Leibnizian physics can be used to develop a theory of relational motion using privileged reference frames. Although numerous problems will remain for a consistent Leibnizian relationist account, the version developed within our investigation will advance the work of previous commentators by more accurately reflecting the specific details of Leibniz’s own natural philosophy, especially his handling (...) of the dynamical interactions of plenum bodies.

Resumen: Propongo una crítica a la noción de serialidad en la comprensión del concepto de tiempo en el contexto de los estudios cartesianos. En el debate entre los defensores del tiempo continuo y quienes defienden un tiempo discreto, sostengo que ninguna de estas posiciones tiene en cuenta que la serialidad se enmarca en una noción de tiempo que se concibe como divisible y numerable y que no pertenece intrínsecamente a la naturaleza de la experiencia temporal del cogito. Mi propuesta consiste (...) en comenzar a desarrollar la caracterización de dicho tiempo experiencial y cogitativo.: My aim is to criticize the notion of seriality embedded in the understanding of time within the framework of Cartesian studies. I hold that neither those who defend that time is continuous nor those who think that it is discrete take into account the fact that seriality is rooted in a conception of time conceived as divisible and numerable that does not belong intrinsically to the nature of the experience of time of the cogito. I propose to advance towards a characterization of such experiential and cogitative time. (shrink)

In this essay, we discuss how Descartes arrives at his mature view of material causation. Descartes’ position changes over time in some very radical ways. The last section spells out his final position as to how causation works in the world of material objects. When considering Descartes’ causal theories, it is useful to distinguish between ‘vertical’ and ‘horizontal’ causation. The vertical perspective addresses God’s relation to creation. God is essential being, and every being other than God depends upon God in (...) order to exist and to continue in existence.Thus, from the vertical perspective, the act of creating and fact of coming into existence are co-extensive notions. This metaphysical/theological framework is the basis of Descartes’ commitment to three interrelated notions: that genuine causes and effects occur simultaneously; that causing is appropriately the case only when the cause is acting; and the view that God is the efficient, total, and continuous cause of everything that exists and every action that occurs. So from the vertical perspective, things are nothing without God’s continuous creation, and there is a problem in articulating how they are said to have independent being and causal efficacy. It is in terms of these commitments that Descartes’ views on horizontal, or material, causation must be approached. We will make apparent the radical extent to which his account of intra-worldly causation abandons his earlier and more traditional views about material causation. To this end we discuss Descartes’ journey to his mature position by emphasizing the growing epistemic limitations of his philosophy, which culminate in what we call his epistemic stance. (shrink)
