Social philosophy is the study of questions about social behavior and interpretations of society and social institutions in terms of ethical values rather than empirical relations. Social philosophers place new emphasis on understanding the social contexts for political, legal, moral, and cultural questions, and to the development of novel theoretical frameworks, from social ontology to care ethics to cosmopolitan theories of democracy, human rights, gender equity and global justice.

Political philosophy, or political theory, is the study of topics such as 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, if anything, 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.
