Written in the era of the postmodernist attack on science, and one of the few books in English (?) that discusses Spengler's 'Decline of the West'. Noteworthy for that alone, if you're one of the few who's read at least some chapters of Spengler. I found the discussion of Mach's Principle in the context of 'holism' to be scientifically enlightening and useful. It's good to learn to distinguish the relativity principle from 'relativism'. Mach had no idea of the difference.
