[ED NOTE: The late biologist Ernst Mayr once noted that "Edge is a conversation." And the "content" of Edge is the more than 1,000 people who have connected in this way over the last twenty-two years. There is a new set of metaphors to describe ourselves, our minds, the universe, and all of the things we know in it, and it is the intellectuals with these new ideas and images, those scientists and others in the empirical world doing things and writing their own books, who drive our times. We are pleased to present our summer reading edition, consisting of the published books by members of the Edge community in the past year or so. —JB [2]]
