A reader mentioned Venice with regard to my Pirate post last week.The following from Webster Tarpley is the first transcription of a number of talks he gave on the subject back in the 80's...

[....Periods of history marked, like the one we are living through, by the convulsive instability of human institutions pose a special challenge for those who seek to base their actions on adequate and authentic knowledge of historical process. Such knowledge can come only through viewing history as the lawful interplay of contending conspiracies pitting Platonists against their epistemological and political adversaries.
