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.

Imre Lakatos’ idea that history of science without philosophy of science is blind may still be given a plausible interpretation today, even though his theory of the methodology of scientific research programmes has been rejected. The latter theory captures neither rationality in science nor the sense in which history must be told in a rational fashion. Nonetheless, Lakatos was right in insisting that the discipline of history consists of written rational reconstructions. In this paper, we will examine possible ways to cash out different, philosophically interesting, relationships: between rationality and science, between rationality and philosophy of science and/or epistemology, and, of course, between history and philosophy of science. Our conclusion is that the historian of science may be a philosopher of science as weIl, but if that philosophy of science is essentially a historical and dogmatic, it either cannot be used for history or it will deprive history of some of its most interesting and useful categories

Traditionally it has been thought that scientific controversies can always be resolved on the basis of empirical data. Recently, however, social constructionists have claimed that the outcome of scientific debates is strongly influenced by non-evidential factors such as the rhetorical prowess and professional clout of the participants. This volume of previously unpublished essays by well-known philosophers of science presents historical studies and philosophical analyses that undermine the plausibility of an extreme social constructionist perspective while also indicating the need for a richer and more realistic account of scientific rationality.

One of the perennial themes in philosophy is the problem of our access to the world around us; do our perceptual systems bring us into contact with the world as it is or does perception depend upon our individual conceptual frameworks? This volume of new essays examines reference as it relates to perception, action and realism, and the questions which arise if there is no neutral perspective or independent way to know the world. The essays discuss the nature of referring, concentrating on the way perceptual reference links us with the observable world, and go on to examine the implications of theories of perceptual reference for realism and the way in which scientific theories refer and thus connect us with the world. They will be of interest to a wide range of readers in philosophy of science, epistemology, philosophy of psychology, cognitive science and action theory.
