For those that are unaware of it, Popper is the intellectual who mentored George Soros...I have read Popper's Open Society and Its Enemies, and rogerv has made a fairly concise statement of Popper's contentions. The problem is, the "open society" Popper espoused is informed, structured by and internally butressed with philosophies that have now been tried and found wanting on the global stage.
Popper's mentoring of Soros aside, the premises of his arguments are flawed at the base. This is a house (or society) that will not stand.
