 What is the relationship, then, between the general causal principle of the Second Analogy and the particular causal laws whose existence, according to Kant, is required by the causal principle? What, more generally, is the relationship between the transcendental synthetic a priori principles of the understanding (including all three Analogies of Experience—compare the end of  note 3  above—as well as the principles corresponding to the other categories) and the more particular synthetic a posteriori laws of nature involved in specific causal relationships governing empirically characterized events and processes? The relationship cannot be deductive; for, if one could deductively derive the particular causal laws from the transcendental principles of the understanding, then the former would have to be synthetic a priori as well.
