Modern academic definitions of the state frequently include the criteria that a state has to be recognized as such by the international community. Liberal thought provides another possible teleology of the state. According to John Locke, the goal of the state or commonwealth is "the preservation of property" (Second Treatise on Government), with 'property' in Locke's work referring not only to personal possessions but also to one's life and liberty. On this account, the state provides the basis for social cohesion and productivity, creating incentives for wealth-creation by providing guarantees of protection for one's life, liberty and personal property. Provision of public goods is considered by some such as Adam Smith as a central function of the state, since these goods would otherwise be underprovided. Tilly has challenged narratives of the state as being the result of a societal contract or provision of services in a free market – he characterizes the state more akin as a protection racket in the vein of organized crime. While economic and political philosophers have contested the monopolistic tendency of states, Robert Nozick argues that the use of force naturally tends towards monopoly. Another commonly accepted definition of the state is the one given at the Montevideo Convention on Rights and Duties of States in 1933. It provides that "[t]he state as a person of international law should possess the following qualifications: (a) a permanent population; (b) a defined territory; (c) government; and (d) capacity to enter into relations with the other states." And that "[t]he federal state shall constitute a sole person in the eyes of international law." Confounding the definition problem is that "state" and "government" are often used as synonyms in common conversation and even some academic discourse. According to this definition schema, the states are nonphysical persons of international law, governments are organizations of people. The relationship between a government and its state is one
