Query: Plenty of gossip; little information

Well, Strathern is certainly entertaining, if not informative. He gives us the dirt on each philosopher, tells us who was overweight, cheap, pushed people around, etc. This would be great if we were reading about movie stars or politicians but I bought these books in order to understand something about what these philosophers thought. He does reserve a few pages at the end of each volume to tells us one or two of their ideas and gives us a handful of quotes. A total waste of money unless you hate your philosophy classes so much that you want to hear how awful the personal lives of the philosophers were. A new low in publishing.
