Social philosophy is the philosophical study of questions about social behavior (typically, of humans). Social philosophy addresses a wide range of subjects, from individual meanings to legitimacy of laws, from the social contract to criteria for revolution, from the functions of everyday actions to the effects of science on culture, from changes in human demographics to the collective order of a wasp's nest. Social philosophy attempts to understand the patterns and nuances, changes and tendencies of societies. It is a wide field with many subdisciplines.
Political philosophy is the study of questions about the city, government, politics, liberty, justice, property, rights, law and the enforcement of a legal code by authority: what they are, why (or even if) they are needed, what makes a government legitimate, what rights and freedoms it should protect and why, what form it should take and why, what the law is, and what duties citizens owe to a legitimate government, if any, and when it may be legitimately overthrown—if ever. In a vernacular sense, the term "political philosophy" often refers to a general view, or specific ethic, political belief or attitude, about politics that does not necessarily belong to the technical discipline of philosophy.
Political philosophy can also be understood by analysing it through the perspectives of metaphysics, epistemology and axiology thereby unearthing the ultimate reality side, the knowledge or methodical side and the value aspects of politics.
A society is a body of humans generally seen as a community. or group of humans or other organisms of a single species that is delineated by the bounds of cultural identity, social solidarity, functional interdependence, or eusociality. Human societies are characterized by patterns of relationships between individuals that share a distinctive culture or institutions. Like other groups, a society allows its individual members to achieve individual needs or wishes that they could not fulfill separately by themselves, without the existence of the social group. Society, however, may be unique in that it is ontologically independent of, and utterly irreducible to, the qualities of its constituent individuals. As a reality sui generis, or "of its own kind", it is emergently composed of social facts that often hinder rather than help the pursuits of the subjects that form its physical and psychological underpinnings.
