I've just bought my copy of this book and am about 61 pages in.
I am greatly excited about the work of the author who has invested many years of research into the subject. Hats off to him and I feel like I am sitting on a shoulder of a giant for all the hard work him and the people around him have given.
Mine is a reprint (2018). I first came across him through his hosts, the CPGB-PCC in the UK. That event, called Communist University, left saying Kautsky, Kautsky, Kautsky. I was the same.
Though I have just started reading the book, notably I find it very readable. It is very readable. An personal affinity I have to the author is that he got his PHD in the year that I was born.
Looking back at the revolutions in Europe at the end of the 19th and through the 20th Century, and perhaps thinking 'what went wrong' this author has managed to connect me to all of it. Through all the wars that are happening in the political left with circles getting smaller and smaller there are some green shoots emerging.
I confidently believe that many (if not all) of the green shoots will come out of the reconnection of the fourth internationals, the third to the first and second, and this author is a guiding light for parts and all of it.
