Did you know?

Ideology has been in use in English since the end of the 18th century and is one of the few words whose coiner we can identify. The French writer A. L. C. Destutt de Tracy proposed it as a term to designate the “science of ideas,” and in that sense the word was quickly borrowed into English. Though ideology originated as a serious philosophical term, within a few decades it took on connotations of impracticality thanks to Napoleon, who used it in a derisive manner. Such connotations are still present in some contexts, but the word today is largely used neutrally, most often to refer to a systematic body of concepts, and especially to the set of ideas and beliefs held by a particular group or political party.
