Abstract
In this article, I set forth a theory of propaganda explaining what it is, how it relates to marketing, and the nature and types
of ideology. I discuss the criteria by which we can judge the rationality or deceitfulness of propaganda. I defend the view
that while propaganda can be perfectly rational, it rarely is, and I explain why that is the case. I finish by explaining why the
question of the rationality or deceitfulness of propaganda is different from the question of the morality of propaganda. I give
two quick examples of how an ethicist might argue that deceptive propaganda might be ethical to use, and perfectly rational
propaganda might be immoral to use. I conclude with the notion that the question of the ethics of marketing and propaganda
is complex, and should be handled in a separate paper
