This book is a shout of joy that mankind has come to its time of reward, that it is just awakening from a protracted restless nightmare into a new kind of light, bright with sensuous delight.
I read this book when it first came out and found it inspiring. Now, however, much of the book seems silly and off-target. The idea that human technology has somehow now mastered the earth is laughable in a world where technology seems to be destroying the climate and we are unsure if technology alone can change this. Another silly aspect of the book is the messianic language in a book that wants to claim religious ideas are dead. As Hanna gets all giddy and prophetic about the unstoppable revolution we are in, I feel that someone should be shouting Hallelujah and Praise the Lord. It also seems silly how he puts down Hegel for making the course of history seem inevitable, and then constantly repeats how his own vision of change is unstoppable and inevitable. Some of the information on the scientists and philosophers is good but, all too often, Hanna talks so much about his interpretation that what the philosopher actually says seems besides the point. This book was thought-provoking in 1970, but its predictions now seem misguided and incorrect.
