Libertarianism
Objectivists are libertarians who believe in atheism. They believe that humans are able to know things, as opposed to skepticism, which is the idea that people cannot know things with certainty. They believe reason is the only path to truth, and that a system of free capitalism is the only ethical system of government. The most prominent objectivist is Ayn Rand. (There are also some "anarcho-objectivists", such as Linda & Morris Tannehill and Roy A. Childs, Jr.)
