Abstract

IN “What Morality is Not”, Philosophy , XXXII , Mr. Alasdair Maclntyre argues against the view, now common, “that universal–izability is of the essence of moral valuation”. On page 331 he uses an argument which is an adaptation and extension of Moore's naturalistic fallacy argument, and which is generalizable. As Moore's argument, if cogent, holds against all definitions of “good”, “right”, etc., so Maclntyre's argument, if good, holds against all definitions of “moral” and “morality”. For this reason I shall examine his argument, as I once examined Moore's.1 I wish to do this partly because I should like to go on looking for definitions or elucidations of words like “moral” such as are contained in the uni–versalizability view, and partly in order to air some general questions which are raised by what Maclntyre says
