逻辑实证主义
The question of religious language and in what sense it can be said to be meaningful has been a central issue of the philosophy of religion since the work of the Vienna circle, a group of philosophers who, influenced by Wittgenstein, put forth the theory of Logical positivism. Their view was that religious language, such as any talk of God cannot be verified empirically and thus was ultimately meaningless. This position has also been termed theological noncognitivism. A similar view can be seen in David Hume's An Enquiry Concerning Human Understanding, where he famously wrote that any work which did not include either (1) abstract reasoning on quantity or number or (2) reasoning concerning matter of fact and existence was "nothing but sophistry and illusion".
