Kant’s dissertation for the Master’s degree Succinct Exposition of Some Meditations on Fire was written in Latin in 1755 as a sample (specimen) preceding a Master’s exam, but its first printing did not appear until 1838. What is the relevance of this Master’s dissertation for historical and philosophical studies? To answer this question I analyse the structure and give a brief summary of the dissertation, look at the history of its writing and try to identify the place of this work (...) among Kant’s other papers on natural philosophy. I then demonstrate that Kant’s concept of ether as an elastic matter of fire, heat and light containing the forces of attraction and repulsion originates in the dissertation On Fire. I identify the provisions in Kant’s early works which he later develops in the Master’s dissertation and establish continuity between the text of On Fire and the so-called Physical Monadology, draw parallels between the ideas enunciated by Kant in his first dissertation and the interpretation of ether in the printed works that followed. Finally, I put forward the hypothesis of the heuristic potential of the On Fire treatise for the analysis of Kant’s manuscript legacy. Perhaps this dissertation will enable researchers to clear up some tangled propositions in Kant’s Opus Postumum. However, a series of further studies is needed to verify the hypothesis. (shrink)

In his Groundwork of the Metaphysics of Morals , Kant explains that ethics, like physics, ‘will have its empirical part, but it will also have a rational part, … though here [in ethics] the empirical part might be given the special name practical anthropology’ . In the Groundwork, Kant suggests that anthropology, or the ‘power of judgment sharpened by experience’, has two roles, ‘to distinguish in what cases [moral laws] are applicable’ and ‘to gain for [moral laws] access to the (...) human will’ . Twelve years later, the first function, of applying the categorical imperative to specifically human situations, is incorporated into Kant's Metaphysics of Morals. (shrink)

Kant's reasoning in his special metaphysics of nature is often opaque, and the character of his a priori foundation for Newtonian science is the subject of some controversy. Recent literature on the Metaphysical Foundations of Natural Science has fallen well short of consensus on the aims and reasoning in the work. Various of the doctrines and even the character of the reasoning in the Metaphysical Foundations have been taken to present insuperable obstacles to accepting Kant's claim to ground Newtonian science. (...) Gordon Brittan and Gerd Buchdahl, amongst others, have argued that Kant's stated aims in this case are not to be taken at face value, and that prior ontological commitments play a hidden but central role in Kant's special metaphysics. ;Michael Friedman has shown how Kant's stated aims can be taken seriously with his ingenious reconstruction of the Metaphysical Foundations as a demonstration of the a priori basis for our thinking bodies to be in true motion and in absolute space. However, Friedman does not address the issue of matter theory--despite the importance of the issue to Kant. I argue that a strict reading of both the stated aims and doctrines of the Metaphysical Foundations is possible, since much of Kant's reasoning about the empirical concept of matter can be explained by his views on how the construction of empirical concepts is possible. ;Kant's quasi-mathematical constructions are pivotal in Friedman's interpretation. Constructibility is Kant's criterion of acceptability for the concepts of natural science. Yet Kant notoriously fails to construct the dynamical concept of matter, and accepts this failure with an equally notorious complacency. I argue that Kant's criteria of empirical concept construction, apart from any prior ontological commitments, are enough to generate his views on matter. Kant's failure to construct the requisite concept of matter can be ascribed to a missing law of nature, a law of the relation of forces the discovery of which Kant thought imminent. I conclude that matter theory is central to the Metaphysical Foundations, but that this does not undermine Kant's stated aim of giving the a priori ground of Newtonian science. (shrink)
