Sorry I've never heard anything about the society of positivist proletarians. Auguste Comte sympathized with the working masses but was still fairly elitist so I doubt he would have formed a society under that name, and on the contrary I think the only group he ever organized was the church of humanity.
You might be able to help me find material on Society of Positivist Proletarians (posted about this in Learning-Research).
Hey I noticed that you commented on my wikiwars thread and I'm curious if you actually read any of the posts in the thread because the questions you raised were already answered.
