When did big-picture optimism become cool again? While not blind to potential problems and glitches, Global Brain: The Evolution of Mass Mind From the Big Bang to the 21st Century confidently asserts that our networked culture is not only inevitable but essential for our species' survival and eventual migration into space. Author Howard Bloom, believed by many to be R. Buckminster Fuller's intellectual heir, takes the reader on a dizzying tour of the universe, from its original subatomic particle network to the unimaginable data-processing power of intergalactic communication. His writing is smart and snappy, moving with equal poise through depictions of frenzied bacteria passing along information packets in the form of DNA and nomadic African tribespeople putting their heads together to find water for the next year.

The reader is swept up in Bloom's vision of the power of mass minds and, before long, can't help seeing the similarities between ecosystems, street gangs, and the Internet. Were Bloom not so learned and well-respected--more than a third of his book is devoted to notes and references, and luminaries from Lynn Margulis to Richard Metzger have lined up behind him--it would be tempting to dismiss him as a crank. His enthusiasm, the grand scale of his thinking, and his transcendence of traditional academic disciplines can be daunting, but the new outlook yielded to the persistent is simultaneously exciting and humbling. Bloom takes the old-school, sci-fi dystopian vision of group thinking and turns it around--Global Brain predicts that our future's going to be less like the Borg and more like a great party. --Rob Lightner
