At the time I found it somewhat interesting, but it's one of the books that really didn't stick with me. as I progressed reading through the centuries it was more interesting within the developments of its time and immediately succeeding era. Reading the philosophers I have read, it always struck me they encapsulated a certain essence of the era that followed their time. Probably post hoc selection has a lot to do with why they are still remembered. I think PG is right about most philosophy. I haven't read any at all in over a decade.
