Destutt de Tracy and Marx defined ideology as false consciousness that is a distortion of reality the reality being the class struggle, the distortion the prevailing ideas of the ruling class. Marx and Engels view of ideology is basically negative, although there are signs of a positive view in some of their writings. Lenin gave the concept of ideology a clearly positive thrust by acknowledging that initially ideology stems from the interests of the dominant class, but then goes on to argue that any critique of ideology has to stem from the interests of the dominated class. Some of the ideas that led to the development of political culture theory contributed significantly to what became known as the end of ideology thesis. The developmental view of politics, with which theorists like Almond and Verba were strongly associated, argued that all societies are at different stages on a continuum of economic and political development culminating in liberal-democratic societies.
