Sophisticated positivist and natural law theories sometimes resemble each other more than the above descriptions might suggest, and they may concede certain points to the other "side". Identifying a particular theorist as a positivist or a natural law theorist sometimes involves matters of emphasis and degree, and the particular influences on the theorist's work. In particular, the older natural lawyers, such as Aquinas and John Locke made no distinction between analytic and normative jurisprudence. But modern natural lawyers, such as John Finnis claim to be positivists, while still arguing that law is a basically moral creature.
