Abstract

This collection of twelve essays reexamines Kant’s considered attitude toward particular sciences so as to reevaluate his natural philosophy and its relation to critique, and shows how Kant tries to develop a unified natural philosophy that nevertheless recognizes and respects the diverse standards implicit in various sciences. Manfred Kuehn outlines the intellectual situation at Königsberg at the end of Kant’s schooling, with focus on competing accounts of relations among substances—real change physical influx, occasionalism, and universal harmony—arguing centrally that Kant’s Thoughts on the True Estimation of Living Forces was an act of rebellion against Martin Knutzen, leader of the dominating, anti-Wolffian Pietists, who argued for the sufficiency of influx and the dangers of preestablished harmony. Kant argued that while physical influx correctly accounts for some kinds of changes, a full account of reality requires harmony not only of the internal states of substances, but, going beyond the Leibnizians, external interactions of substances also.
