proudon who was the first to call himself an anarchist in like 1850 was not aligned with marx - they knew one another but... he was not a socialist and certainly not a marxist he worked on mutualism which is structurally incredibly different and majorly egalitarian (no state rule whatsoever autocratic or otherwise)
i dont think in a dualist manner either communism or capitalism there are different ways
proudon dealt a lot with the issue of property which is an incredibly difficult issue to deal with and some say if the french during the revolution would have dealt solidly with the issue of property (a giant problem because of the elite) there would have been a much more transformed world after and a 'real' revolution
he had some things in common with diderot as he dealt with intellectual property a lot - educating the masses... information flow for the people
i will read your link of course - thanks
