Brockman is an interesting man and a good editor for this anthology. The premise of Third Culture is unique: taking its title and approach from C.P. Snow's famed essay "The Two Cultures", which concerned the divide between liberal arts/social sciences knowledge fields and knowledge of the hard and life sciences in society, Brockman has brought together essays from leading scientists such as Richard Dawkins, Daniel Dennett, and Lynn Margulis about their specific areas of science and geared towards a lay readership, thus explaining cutting-edge research (at the time of publication, around 1996, at least) in a way people can understand its importance.
In general, it's a good collection, but it's heavy on the biosciences and I would have liked to have seen more on the so-called hard sciences (physics, chemistry, astronomy) and also some inclusion of various aspects of applied engineering. Someone who is an engineer or scientist yet involved in national policy like Dr. Janet Fender (optics expert and USAF scientist) would have been great in this volume. Moreover, there is not enough bringing together the various essays . . . Brockman himself could have, and should have, written more supportive material to make clear how what, say, Dennett writes of is associated with another author's content. It feels too thrown-together in places, and yet if you know how bright and detail-oriented Brockman is, you'd expect him to have a fine-tailored effort without nearly a comma out of place. That said, it's a rare anthology and contains some great writing.
