Thomas Sowell Politics	When issues of public policy are discussed in the outward form of an argument, often the conclusions reached are predetermined by the assumptions and definitions inherent in a particular vision of social processes. Different visions, of course, have different assumptions.... To a remarkable extent, however, empirical evidence is neither sought beforehand nor consulted after a policy has been instituted. Facts may be marshaled for a position already taken, but that is very different from systematically testing opposing theories by evidence. Momentous questions are dealt with essentially as conflicts of vision.
