 Marx does not view ideology as a feature of all societies, and, in particular, suggests that it will not be a feature of a future communist society. However, ideology is portrayed as a feature of all class-divided societies, and not only of capitalist society—although many of Marx’s comments on ideology are concerned with the latter. The theory of ideology appears to play a role in explaining a feature of class-divided societies which might otherwise appear puzzling, namely what might be called their “stability”; that is, the absence of overt and serious conflict between social classes. This stability is not permanent, but it can last for extended historical periods. This stability appears puzzling to Marx because class-divided societies are flawed in ways which not only frustrate human flourishing, but also work to the material advantage of the ruling minority. Why do the subordinate classes, who form a majority, tolerate these flaws, when resistance and rebellion of various kinds might be in their objective interests?
