NATURE

[A216/B263] After giving the three Analogies of Experience, Kant defines nature as follows: "By nature, in the empirical sense, we understand the connection of appearances as regards their existence according to necessary rules, that is, according to laws". The Analogies provide "transcendental laws of nature", which he also characterizes as "a priori propositions that are intellectual and at the same time synthetic". (Here he discusses why synthetic apriori truths, such those in the Analogies of Experience, the Anticipations of Perception, and the Principle of Sufficient Reason, cannot be proved dogmatically.)
