>>21918>I mean you can do some materialist analysis of the evolution of societies through history based on the material economic conditions and technical/technological progress,That still assumes there's a fixed objective trajectory for human development which there isn't. Even technological changes are simply choices shaped by power not objective improvements. e.g. why did steam power prevail over hydro? We assume steam is inherently better but better for whom? Steam gave more control and power to bourgeois factory owners and turned out to be more profitable so the vast water works the English parliament wanted to build were cancelled. Steam emerged in countries that burned coal in place of wood during shortages, unlike the Middle East where olive oil and crude were used. This tech may never have developed in another geographic environment. Technological change isn't like a tech tree and what counts as an improvement really depends on your perspective. A steel mill is good for us if we're Qing bureaucrats trying to strengthen our empire against the West, but if we're the peasants who have to live with the smoke, noise, and horrible working environment then technology hasn't improved at all.
>I think feudalism is still a useful conceptIf historians and experts in that time period have ditched it and have been saying its unhelpful since the 70s, then I'm not going to challenge them. What might make feudalism useful otherwise? Its politically useful? I'm not sure. If you look at the damage done during the Cultural Revolution you can see how an idea like "feudalism" has had disastrous consequences. Ordinary activists during GPCR tore down archeological sites, raided temples, burned classical literature, beat up Buddhist monks etc. all in the name of combating "feudalism" this mythical reactionary ideology that supposedly had its tentacles everywhere and had to be rooted out. Another example is Turkey's infamous hat law which banned traditional clothing. All they succeeded in doing was bankrupting fez manufacturers and weakening the local economy just because Ataturk thought fezzes and turbans are backward and feudal. In Japan, virtually anything bad is blamed on "feudalism" which never existed.
