Abstract
Julius Kovesi's accomplishment in Moral Notions is without limit. Kovesi has the more powerful account of conceptuality. Hart would have benefited greatly from Kovesi's distinction between formal and material elements. It provides precisely the correct antidote to debates that never lift themselves out of sparring about particular features of diverse objects. If this is not progress, then to know what is. Kovesi's accomplishment was in giving us a complete and utterly convincing account of what we mean when we say 'these two things are the same'. No one in legal theory has provided a better account of this form of reasoning.
