Throughout history we observe that people use political language in the way accorded to them by tradition, even when that political language — that conceptual language — no longer corresponds to reality. I think this is happening today among Communists and Marxists in Brazil.
Yes, I like seeing articles/talks by communists from other countries. There’s always something new to learn.
Roderic Day seems to be one of the few people (at least that I’m aware of) involved in translating some of these to English and publishing them.
