ABSTRACT
This chapter begins consideration of the tasks of argument criticism. Premise criticism is to be is distinguished from criticizing the move of reasoning. The basic intellectual skill of logic criticism is that of being able to tell when a conclusion follows from the argument's premises. The chapter discusses the logicality or otherwise of the sorts of arguments that are common in discussions of professional ethical issues. As there might be more than one distinct hole, the process of patching might have to be repeated always try to patch holes but also try to have the patched version in the spirit of the original and without making the new, patching, premises unduly implausible. Distinguish the distinct tasks of criticizing a given argument to appraise its merits as a case for its conclusion and mounting a quite separate argument as a case for the opposite conclusion.
