The main topic of the following dissertation is Kant's Third Analogy of Experience, which asserts that one must posit a bond of mutual interaction in order to judge that two substances exist simultaneously. Part One considers the Third Analogy proper and reconstructs two plausible arguments for its main claim. Contrary to the view of most commentators , Kant is entitled to a strong causal notion of mutual interaction. Part Two considers the historical debate between proponents of Pre-established Harmony, Occasionalism, and (...) Physical Influx and how the Third Analogy can be seen as Kant's most developed version of Physical Influx. Thus, we see that Kant's concern with causality is not exhausted by his reply to Hume in the Second Analogy of Experience. For Kant is clearly concerned to attack the rationalist tradition by criticizing Leibniz's and Wolff's Pre-established Harmony, on the one hand, and the Cartesians' and Malebranche's Occasionalism, on the other hand. Part Three considers the argumentative structure of Kant's Metaphysische Anfangsgrunde der Naturwissenschaft and how the Third Analogy relates to this work. Contrary to what one might expect, the MAdN does not proceed by first presupposing a Principle from the first Critique and then substituting in the concept of matter. Rather, its substantial results are obtained through an extended transcendental argument showing how we can have experience of objects of outer sense . Further, we see how the abstract notion of mutual interaction involved in the Third Analogy becomes more specific in the MAdN since two of the most important features of its central notion of matter, namely the capacities of filling a space and of communicating motion, require attractive and repulsive forces and action and reaction, both instances of mutual interaction. These three lines of argument establish that the Third Analogy of Experience both constitutes a crucial part of Kant's position and presents a philosophically plausible view. (shrink)

The aim of this essay is to introduce philosophers of science to some recent philosophical discussions of the nature and origin of the direction of time. The essay is organized around books by Hans Reichenbach, Paul Horwich, and Huw Price. I outline their major arguments and treat certain critical points in detail. I speculate at the end about the ways in which the subject may continue to develop and in which it may connect with other areas of philosophy.

The paper criticizes the attempt to account for the direction of causation in terms of objective statistical asymmetries, such as those of the fork asymmetry. Following Ramsey, I argue that the most plausible way to account for causal asymmetry is to regard it as "put in by hand", that is as a feature that agents project onto the world. Its temporal orientation stems from that of ourselves as agents. The crucial statistical asymmetry is an anthropocentric one, namely that we take (...) our actions to be statistically independent of everything except (what we come to call) their effects. I argue that this account explains the intuitive plausibility of Reichenbach's principle of the common cause. (shrink)

The Reichenbach-Grunbaum thesis of the conventionality of simultaneity is clarified and defended by developing the consequences of the Special Theory when assumptions are not made concerning the one-way speed of light. It is first shown that the conventionality of simultaneity leads immediately to the conventionality of all relative speeds. From this result, the general-length-contraction and time-dilation relations are then derived. Next, the place of time-dilation and length-contraction effects within the Special Theory is examined in the light of the conventionality thesis. (...) The slow-transport method of synchrony is then examined in the light of these results and is shown not to provide an adequate method of uniquely determining the one-way speed of light. Finally, the general ε -Lorentz transformations for events along the x-axis are derived from three principles: the round-trip light principle, the principle of equal passage times, and the linearity principle. These principles are shown to be independent of one-way velocity assumptions, and thus may form the basis of a Special Theory of Relativity without distant simultaneity assumptions. (shrink)

This paper examines Wesley Salmon's "process" theory of causality, arguing in particular that there are four areas of inadequacy. These are that the theory is circular, that it is too vague at a crucial point, that statistical forks do not serve their intended purpose, and that Salmon has not adequately demonstrated that the theory avoids Hume's strictures about "hidden powers". A new theory is suggested, based on "conserved quantities", which fulfills Salmon's broad objectives, and which avoids the problems discussed.

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

This paper defends the view that the asymmetry of causation can be explained in terms of probabilistic relationships between event types. Papineau first explores three different versions of the "fork asymmetry", namely David Lewis' asymmetry of overdetermination, the screening-off property of common causes, and Spirtes', Glymour's and Scheines' analysis of probabilistic graphs. He then argues that this fork asymmetry is both a genuine phenomenon and a satisfactory metaphysical reduction of causal asymmetry. In his final section he shows how this reduction (...) can account for the relevance of causal direction to human agency, and in particular for the fact that we can manipulate causes to influence their effects, but not vice versa.

Kant's theory of matter is reconstructed and his views about and impact on chemistry are studied. His early "monadological" conception is analyzed and compared to other dynamical approaches of the period. His later attempt to regard matter as a continuum and to derive some of its properties from the interaction of forces is reconstructed. His conception of chemistry is examined and compared to the notion of some chemists who were inspired by Kant's work.
