Many writers assume one of the major functions (if not the major function) of ethical theory is to analyze the “ordinary language”; of moral discourse. This paper argues that different social groups develop quite different concepts of values; that there are many “ordinary languages.”; What analysts often in practice arc concerned with is middle-class ethical usage. In addition, it is argued that widely accepted moral usages may be incorrect because they are based on faulty empirical generalizations, pre-scientific opinions, or socially-determined (...) prejudices. “Ordinary language”; needs to be viewed critically, therefore, rather than to be assumed as correct.
