In 1747, Kant believed that the mind/body problem presupposed several false and interrelated assumptions that fell under the general view that the essential force of body is vis motrix, namely that bodies act only by causing changes of motion, that bodies can be acted upon only by being moved, and that souls and bodies do not share a common force. He argued in Thoughts on the True Estimation of Living Forces that the traditional vis motrix view, which was defended by (...) Wolff, appealed to an unexplanatory and metaphysically incoherent conception of force. ;Kant maintained that God acted to unify our world in such a way that all its finite substances possess a vis activa capable of producing motion in bodies and representations in souls. Unlike Leibniz's account of vis activa, Kant's account was compatible with the existence of transeunt or externally-directed forces. Indeed, Kant argued that every change in our world involves the exercise of a transeunt force. ;In Living Forces, Kant used these ideas to solve the mind/body problem. This study evaluates Kant's solution and traces his responses in later pre-critical texts to several acute difficulties. Chief among these difficulties was that his account of the "divine schema" of our world was incompatible with his metaphysical dualism: to exist in our world, Kant argued, all substances must possess attractive and repulsive forces, but attributing these forces to souls implied that they also possessed the same material nature as the physical monads out of which material bodies are composed. ;Kant did not recognize this problem until the early 1760s, and in the Dreams of a Spirit-Seer he maintained that it was insoluble. In the Meta-physik L1 lectures , Kant articulated a new understanding of the mind/body problem that centered on the idea that the body is an object of outer sense and the soul an object of inner sense. ;I conclude that, although his understanding of mind/body connectedness remained inadequate in the mid-1770s, Kant's struggles with this and related issues contributed to the development of systematic critical strictures on meta-physical reasoning and to the critical theory of inner sense.

In the paper author advocates rejecting a prominent criticism of Marx, which holds that his condemnation of capitalism fails because it is based on incoherent, inconsistent moral reasoning. To rebut this criticism he investigates Marx’s conception of ideological illusion, arguing that some moral judgments could be true even if people always possess moral beliefs because of ideological illusion. To support this thesis he provides epistemological argument about the nature of epistemic justification, proving that on any reasonable interpretation of knowledge, justification (...) of moral beliefs is possible under even the extreme conditions of ideological illusion. He then introduces the final theme of the essay, namely that strikingly Aristotelian themes lie at the heart of Marx’s ethical condemnation of capitalism. By discussing the similarity of Marx’s account of alienation to Aristotle’s account of self-actualization he shows that both thinkers explicitly connect their accounts of development and actualization of human potential and freedom within a society with a sharp critique of economic forms that block or retard that development and actualization. Key words ARISTOTLE, MARXISM, CAPITALISM. (shrink)

I discuss the philosophical significance of Kant's great cosmological work of 1755, the Universal Natural History. I discuss how Kant's interest in Newtonian universal forces led him to affirm a peculiar version of the physical influx theory. I argue that Kant's speculations about life on other planets are highly significant because they point to a key feature of Kant's theory of physical influx, namely that "the nimble motions of the body" stand as necessary conditions of the possibility of knowledge. This (...) work directs us to an important topic that has received little scholarly interest: the relation between the body and knowledge in Kant's philosophical writings. (shrink)

This essay considers attempts to refute scepticism by transcendental argumentation; in particular I explore attempts to refute traditional "Cartesian" scepticism with idealistic transcendental arguments. My main conclusions are: Transcendental arguments are indispensable for a refutation of scepticism, not redundant; Idealistic transcendental arguments cannot refute Cartesian sceptical doubts; Traditional sceptical doubts can be reformulated so as to be effective against accounts of knowledge based on an idealistic theory of truth; It is possible in principle that idealistic ("Kantian") transcendental arguments can refute (...) such idealistic sceptical doubts and also that non-idealistic ("Strawsonian") transcendental arguments can refute non-idealistic doubts; Merely to assume a theory of truth and just to dismiss certain sceptical doubts based on another theory of truth is to beg the question against the sceptic; but all arguments for a particular theory of truth beg the question against radical sceptics; Because radical scepticism must be taken seriously, a complete refutation of scepticism would require constructing both types of transcendental arguments, viz. Kantian idealistic arguments (to refute idealistic doubts) and Strawsonian non-idealistic arguments (to refute non-idealistic, "Cartesian" doubts). I argue that the allure of idealism as a way to refute scepticism is wholly unfounded, viz. because (1) sceptical doubts can be reformulated so as to be effective against idealistic conceptions of knowledge and (2) idealistic arguments cannot refute traditional Cartesian doubts. But although it doesn't lead where many have hoped, I argue that--in a strange way, for different reasons than are commonly supposed--idealism represents a road which must nevertheless be taken if scepticism is to be refuted. That is, though most of the essay attempts to establish that refuting Cartesian scepticism requires that they be separated, it also follows from my argument that transcendental arguments and transcendental idealism must not be kept apart if scepticism is to be fully refuted..
