History moves only in one direction and once the material and economic conditions of one historical epoch are present, one cannot return to past modes of production or, significantly, modes of social existence. According to Marx, economic conditions determine all other aspects of society, and so it is impossible to keep these levels apart for long.

While we may often be seduced by the idea that forward is always better, one must provide a theoretical basis for this; change for change's sake is not always good. Marx does, of course, provide a justification for this, which we have assessed independently. Without such a justification it is certainly an open question as whether the problems of the present can be solved by looking to the wisdom of one's predecessors or only by forging a new and unique future. Also, paradoxically enough, Marx's analysis of the relationship between economics and culture may give fodder to certain reactionary movements, giving them a reason to prevent the inclusion of new technologies because it will inevitably end up changing their social ideologies.

They might believe that slow and steady reforms are the best way to ameliorate proletariat anxiety, or they might believe that quicker, more radical departures from the past are needed. In either case, though, they still want to suppress the revolutionary ...
