Wow. Things have been hopping around here! Arch is pissed, and Mono has developed several new ways to say epic fantasy is crap... The world does turn on greased grooves!
Very interesting article, Aldarion - and on a topic close to my heart. Regarding
my guess would be that most everyone mentioned subscribes to the principle of interpretative underdetermination, which is just to say they would likely agree with you.
Istvan's central argument, I take it, is that the traditional Marxist commitment to materialism denies it the theoretical resources it needs to generate an adequate theory of fantasy. Of course he assumes that 'adequacy' here involves a positive evaluative component.
Some fantasy is good. Marxism says all fantasy is bad. Therefore, Marxism has a problem.
What's cooking my bean is the sense in which classical or vulgar Marxism can be read as a
theoretical version of epic fantasy. It gives one a place in a (albeit historicized) cosmic order, and it promises perpetual apocalypse (revolution); two key generic markers of epic fantasy.
Perhaps the antipathy has as much do with this: in epic fantasy, Freedman et al see their theoretical vulnerabilities writ large.
