Book excerpt: This book does much to disple the old canard that John Dewey was guilty of "scientism" and a reverent worship of technological progress. Indeed, Dewey predated the Frankfurt school in his warnings about the dangers inherent in a machine culture. With new advances come new problems, and these can only be dealt with through an instrumentalist approach. Dewey also argued that we have no guarantee of success. Natural events can terminate human life and human greed, laziness, or error could have the same result.
