The body of doctrine or myths or set of beliefs that guides an individual, social movement, institution, class, or large group. An ideology relies on basic assumptions about reality that may or may not have any factual basis. One should note the difference between worldview and ideology. Worldviews constitute one’s core belief system and are mostly philosophical, whereas ideologies constitute one’s secondary belief system and are mostly sociological, political, and/or economic. One’s worldview precedes one’s ideology.
