... the point of economic development attained today leaves the ideological, and especially the ethical, factors greater space for independent activity than was formerly the case. In consequence of this the interdependency of cause and effect between technical, economic evolution, and the evolution of other social tendencies is becoming always more direct, and from that the necessities of the first are losing much of their power of dictating the form of the latter. - Eduard Bernstein 1909, pp 15-16Translated into contemporary Marx-speak, Bernstein clearly grasped that the relative autonomy of what we have traditionally called superstructural phenomena grows as capitalism develops. It's one of those neat ironies of history - the more capitalism drives social development, the less the fruits of that evolution are directly dependent on and determined by the structural tendencies of capitalist economics. As bourgeois and proletarians struggle over their material interests and benefit from the successful prosecution of them, the less that conflict overtly plays a part in conditioning the outlooks of strata and classes. In many ways, this insight precedes the arguments underpinning post-materialism by 70 or 80 years, and implicitly draws attention to cultural struggle long before Gramsci did so.
Not bad for a renegade.
