 A further reason is that, as John Finnis and Ronald Dworkin have both explained in different ways, the word ‘law’ can be used in a variety of senses: the law of the jungle, the law of gravity, laws of thought, Murphy’s law, etc. (Finnis 1980, 6; Dworkin 1986, 104). A definition would have to allow for those senses. It might be an intriguing (and arduous) study in culture and human thought to explain the analogies among those senses, but it is a study that holds out no special promise for understanding the law of a community.
