"Politics is the process and method of gaining or maintaining support for public or common action, the conduct of "decision-making for groups. Although it is usually applied to "governments, political behavior is also observed in "corporate, "academic, "religious, and other institutions. "Political philosophy 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. "Political science is the field devoted to studying political behavior and examining the acquisition and application of "power, or the ability to impose one's will on another. Its practitioners are known as political scientists. Political scientists look at "elections, "public opinion, institutional activities, the "ideologies behind various "politicians and "interest groups, how politicians achieve and wield their influence, and so on.
