He then proceeds to analyse "the logic of moral reasoning," which consists of two parts: The logical criteria by which we distinguish between good and bad moral reasoning, and the limits which distinguish moral from other kinds of reasoning. Mr. Toulmin maintains that there is a clear set of logical criteria peculiar to ethics, to be used in evaluating ethical arguments or reasoning. These criteria are determined by the function or use of such reasoning. Whoever chooses not to accept these (...) criteria is simply not talking about moral reasoning. There are alternative modes of reasoning, each having logical criteria appropriate to it, but there is one set uniquely applicable to the ethical mode. (shrink)
