I don't get how one moves from "any beliefs can be defeated by empirical evidence" to "all knowledge is empirical/no knowledge is a priori. While pushing aside analytic judgments, both Kant and Hume make strong arguments for why synthetic a priori judgments are not only the foundation for natural science, but also for the definitive source of almost all human knowledge.
