ABSTRACT
The theological veto and the logical or linguistic veto may seem to be utterly opposed; for the first bans natural theology in the name of religion, and the second bans it in the name of science. In certain respects the Theological Positivist resembles what one may call the Legal Positivist: the man who is concerned with the laws of a particular country and is indifferent or hostile to any philosophy of law. Besides denouncing philosophical theology as a sin and sweeping aside all religions other than his own, he extends his condemnation within his own religion to other branches of the Church, and within his own branch to all who do not accept his doctrine and even to those who accept it on different grounds. It is more surprising to find that Barth shares Ayer's scepticism about every form of rational ethics, although it is not easy to be sure that he is consistent on this subject.
