 Here is a second definition. Pornography is sexually explicit material (verbal or pictorial) that is primarily designed to produce sexual arousal in viewers. This definition is better: it deals with the problem of anatomy textbooks and the like. Indeed, this definition is one that is frequently employed (or presupposed) in discussions of pornography and censorship (e.g., Williams 1981). Of course, it is important to distinguish here between sexually explicit material that is wholly or primarily designed to produce sexual arousal (i.e., whose only or overriding aim is to produce sexual arousal) and material whose aim is to do this in order to make some other artistic or political point. The film Last Tango in Paris arguably aims to arouse audiences, but this is not its primary aim. It does so in order to make a broader political point.
