The title essay is not necessarily all that convincing but the other essays scrape together a cohesive image for an age beyond the industrial revolution. Re-imagining our own history through Russell's eyes is informative. Imagining a reframe of the present in terms of our potential future can actually change the way we live now. I rarely read a book that changes my thought processes in this way but I read Russell's essays almost a decade ago and the ideas are still with me.
