Oh, this, this is a very important book of course and one of the, one of the astonishing things is the way  totally ignored and if you look through even people who write about psychoanalyses and the social sciences and there's a lot of them, this book is hardly ever mentioned  and I, I normally nowadays routinely look for it in the, in the references and index an and many books th that purport to talk about groups and sociology is never mentioned I think, and those that do don't ever seem to understand what it says.
