It had some good points to think over but there was a large chunk, mostly on one type of philosophy, that reminded me of the phrase, "If you cannot dazzle them with brilliance, baffle them with bullshit!" He went off on this tangent that had nothing to do with the writings of the philosopher that was mentioned. And he took up a third of the book to do it! The last section really just a long essay on the values of Time. Interesting thought and some old hat for long time Dr. Who who have had years of that TV series spouting theories of Time and Relative Dimensions.
