Participating in liberal democratic politics means joining or supporting a political party. It means taking sides about some central political issues. ‘The Experience of Politics: II. Parties and Doctrines’ explains that in every liberal democratic state there will generally be two dominant parties, with several others on the margins of political power. The terms liberalism, conservatism, and socialism, and what distinguishes them from each other, are discussed along with ideologies, doctrines, and the thoughts of John Locke and Edmund Burke. According to Burke, politics is based on the concepts of preservation and reform, and it takes off not from abstract ideas of social perfection, but from the circumstances of the present.
