Stalinism was most certainly, amongst other things. the result of bad philosophy.
Never was a more small minded, petit bourgeois puritanical load of codswallop ever spoken.
I think socialist realism is the logical conclusion of an instrumentalisation of thought, as is the rise of bureaucracy, forced collectivisation and the gulags. Ultimately, you are trying to pre-empt the ends to which the class struggle is waged and to deny everyone (including the working class as a whole) their participation in the full rational determination of ends.
Your thinking is that of the worst kind of bureaucrat.
I think the above is what happens when you think ideas drive history and you see history as the product of great/terrible men.
To my thinking philosophy is something that can do actual harm to the individual. You and revol68 are prime examples. It can be something which confuses and more seriously can mask that confusion with a sense of sophistication. Your comments and revol68's comments on this thread have been clumsy and reactive. Philosophy can be like political propaganda it tends to fuse certain ideas together - where does this fusion of "instrumentalism" and "mechanical materialism" and "Stalinism" come from? At first sight this fusion is bizarre, but it's merely a bucket in which you place everything that's bad (remember I pointed out how Zizek uses the amalgam earlier in the thread).
So the question is if you are philosophising like a political propagandist - we have to ask whose political propaganda you are pushing and what cause it serves.
