This essay identifies and explores three dominant intellectual traditions that critique and theorize about ideology: Marxist, prudentialist, and social scientific. For these traditions, the word ‘ideology’ names interest-serving rationalizations, pseudoscientific totalitarian zealotry, or political outlooks. The blending of these three specialized meanings has generated a colloquial sense of ideology that is philosophically untenable and damaging to political discourse. According to this colloquial sense, all thinking is ideological and we are all ideologues. In response, I instead offer in this essay an adverbial account of ideology. In this account, “ideology” names a kind of epistemic vice. Admitting that this is something we all may do sometimes, I describe how we think when we think ideologically. Finally, I conclude with some suggestions about how education might help us avoid the epistemic vice of ideological thinking.
