There is a point beyond which reliance on such formulas as 'the production of knowledge' leads onto very treacherous ground: knowledge may be conceived of on the model of industrial production, with the result that the existin division of labor and use of machines, especially cybernetic machines, is uncritically accepted; alternatively, the concpet of production as well as the concept of knowledge may be deprived of all specific content, and this from the point of view of the 'object' as well as from that of the 'subject' -- which is to give carte blanche to wild speculation and pure irrationalism.
