Abstract
The chapter discusses the conceptual origins of ideology as a term that described ideology as positive science, which analysed thoughts and ideas, ideology in analogy to sociology, the science of ideas, and the science of society respectively. From here the chapter investigates how ideology was transformed into a concept that epitomized a set of principles about society and government. Ideology became an action-oriented concept for shaping the future. The concept moved away from its original meaning of studying ideas conforming to law, although this meaning still played a certain role in the debate.
