who created the concept of a social contract
Social contract Hugo Grotius (1625), Thomas Hobbes (1651), Samuel Pufendorf (1673), John Locke (1689), Jean-Jacques Rousseau (1762), and Immanuel Kant (1797) are among the most prominent of 17th- and 18th-century theorists of social contract and natural rights. Each solved the problem of political authority in a different way. Grotius posited that individual human beings had natural rights. Thomas Hobbes famously said that in a "state of nature", human life would be "solitary, poor, nasty, brutish and short". In the absence of political order and law, everyone would have unlimited natural freedoms, including the "right to all things" and thus the freedom to plunder, rape, and murder; there would be an endless "war of all against all" (bellum omnium contra omnes). To avoid this, free men contract with each other to establish political community, i.e. civil society, through a social contract in which they all gain security in return for subjecting themselves to an absolute sovereign, one man or an assembly of men. Though the sovereign's edicts may well be arbitrary and tyrannical, Hobbes saw absolute government as the only alternative to the terrifying anarchy of a state of nature. Hobbes asserted that humans consent to abdicate their rights in favor of the absolute authority of government (whether monarchical or parliamentary). Pufendorf disputed Hobbes's equation of a state of nature with war.[3]
The Social Construction of Reality Berger and Luckmann introduced the term "social construction" into the social sciences and were strongly influenced by the work of Alfred Schütz. Their central concept is that people and groups interacting in a social system create, over time, concepts or mental representations of each other's actions, and that these concepts eventually become habituated into reciprocal roles played by the actors in relation to each other. When these roles are made available to other members of society to enter into and play out, the reciprocal interactions are said to be institutionalized. In the process, meaning is embedded in society. Knowledge and people's conceptions (and beliefs) of what reality is become embedded in the institutional fabric of society. Reality is therefore said to be socially constructed.
