Empiricism was a skeptical doctrine originally. It was literally designed by people who thought it was good to reason oneself into doubting everything so that one's dispassion would not be troubled by belief. When it became a dogma, it became impossible to avoid skepticism.
Nevertheless, such skepticism isn't wholly off base. Only God exists. If one predicates "exists" as one does of man and other contingent creatures, then God does not exist. God is nothing, but on account of excellence not privation. Everything relates to this ground as emanation, moments in a process of exitus et reditus that begins, ends, and subsists in God. As it says in the Upanishads, "thou art that."
