Princípio de permanência da substância e reações químicas

Abstract

This article investigates a possible counterpoint to the first Kant’s analogy: chemical reactions. For that, conservation law in general is defined according to the understanding of science. These laws have a constant defined form for all of them and contents that differentiate them. The first analogy of the experience or doctrine of Kant's substance is explained by showing that any change we notice in our perceptions in a certain event is only possible if something in that same event does not change. The link between the doctrine of the substance and chemical equations is based on the example of burning firewood in the Kant’s CPR. To discover the substance of any event (including chemical reactions), the difference between transcendental (philosophical) and empirical (scientific) research is discussed. Empirical research is understood as subordinate to transcendental research, therefore proving that chemistry is compatible with Kant’s substance doctrine.
