Ideologies may also be classified by subject type. Most are social systems, political systems or economic systems. Social ideologies are those that deal with relationships and duties between individuals. Egalitarians may be either procedural, concerned with the process, or substantive, concerned with the end result. Political ideologies range from pluralism to authoritarianism.
Pluralism refers to government by more than one.
This includes hyperpluralism, democracy, republicanism, libertarianism and populism. Authoritarian ideologies concentrate power into the hands of one person or an elite few, such as monarchism, constitutional monarchism, and totalitarianism. Stalin and Hitler are the only real examples of totalitarianism. Economic ideologies refer primarily to the ownership of property. Socialism is distinguished by public ownership of property and a planned economy, not the profit motive.
