This paper explains Kant’s views on the theory of matter as developed in the Dynamics chapter of his Metaphysical Foundations, and elaborates their background in the chemistry of the period. Kant’s general approach to matter theory unites Newtonian and Leibnizian motifs, and entails an intricate internal structure for matter involving a multiple overlap of material shells of different density. Kant’s chemical views derive from Stahlian chemistry and involve a noncorpuscularian account of chemical combination and a nonoperational conception of chemical elements.

This paper notes a number of differences between Newton’s formulations of the laws of motion and Kant’s formulations of the laws of mechanics, and then argues that these differences are not superficial. Their significance can be seen by taking Kant’s rationalist background into account. The essay also contains discussions of Kant’s claims concerning the infinite divisibility of matter, the equality of action and reaction, and action at a distance.

Kant famously declares that “although all our cognition commences with experience, … it does not on that account all arise from experience”. This marks Kant’s disagreement with empiricism, and his contention that human knowledge and experience require both sensation and the use of certain a priori concepts, the Categories. However, this is only the surface of Kant’s much deeper, though neglected view about the nature of reason and judgment. Kant holds that even our a priori concepts are acquired, not from (...) sensation, but “originally,” because our mind has a fundamental capacity to judge that, upon sensory stimulation, generates the Categories through its basic logical functions of judgment. This “epigenesis” of reason and our fundamental capacity to judge that drives it is the topic of Longuenesse’s fascinating book, and the source of her title. (shrink)

This article challenges the prevailing interpretations of Hegel's account of the concept "contradiction" in the Science of Logic by arguing that it is concerned with the principle of Hegel's method rather than with the classical law of non-contradiction. I first consider Hegel's Doctrine of Essence in view of Kant's discussion of the concepts of reflection in the first Critique. On this basis, I examine Hegel's account of the logical principles based on the concepts "identity," "opposition," and "contradiction." Finally, I point (...) out how the principle Hegel derives from the concept of contradiction actually informs his own method. (shrink)

_One summary of the great Kant's view, to the extent that it can be summed up, is_ _that he takes determinism to be a kind of fact, and indeterminism to be another kind_ _of fact, and our freedom to be a fact too -- but takes this situation to have nothing to_ _do with the kind of compatibility of determinism and freedom proclaimed by such_ _Compatibilists as Hobbes and Hume. Thus Kant does not make freedom consistent_ _with determinism by taking (...) up a definition of freedom as voluntariness -- at bottom,_ _being able to do what you want. This he dismisses as a wretched subterfuge,_ _quibbling about words. Rather, the freedom he seeks to make consistent with_ _determinism does indeed seem to be the freedom of the Incompatibilists --_ _origination. Is he then an Incompatibilist? Well, against that, it can be said he does_ _not allow the existence of origination in what can be called the world we know, as_ _Incompatibilists certainly do._. (shrink)

This paper describes the local context of Kant’s scientific education. It provides an informed sense of what Kant’s scientific training was like by presenting each relevant member of the philosophy faculty at the university in Königsberg where Kant was a student, and the scientific activities each one was engaged in. On the basis of this picture, it is argued that Kant’s relationship with one of his teachers, Martin Knutzen, may have been much more negative or critical than is typically supposed. (...) This evaluation has important implications especially for understanding Kant’s early works in natural philosophy. (shrink)
