 In response critics often see this as just another example of sloppy functional reasoning—purportedly widespread in the Marxist tradition—whereby a general pattern is asserted without the identification of any of the mechanisms which might generate that pattern. In the present case, it is said that Marx never properly explains why the ruling ideas should be those of the ruling class (Elster 1985: 473). Yet there are obvious possible mechanisms here. To give two examples. First, there is the control of the ruling class over the means of mental production, and in particular the print and broadcast media which in capitalist societies are typically owned and controlled by the very wealthy (MECW 5, 59). A second possible mechanism appeals to the psychological need of individuals for invented narratives that legitimise or justify their social position; for instance, Marx identifies a widespread need, in flawed societies, for the consolatory effects of religion (MECW 3, 175).
