Now, in What the Dog Saw, he brings together, for the first time, the best of his writing from The New Yorker over the same period. Here you'll find the bittersweet tale of the inventor of the birth control pill, and the dazzling creations of pasta sauce pioneer Howard Moscowitz. Gladwell sits with Ron Popeil, the king of the American kitchen, as he sells rotisserie ovens, and divines the secrets of Cesar Millan, the "dog whisperer" who can calm savage animals with the touch of his hand. He explores intelligence tests and ethnic profiling and why it was that employers in Silicon Valley once tripped over themselves to hire the same college graduate.

    Biomedical enhancements, he writes, can make us smarter, have better memories, be stronger, quicker, have more stamina, live much longer, be more resistant to disease and to the frailties of aging, and enjoy richer emotional lives. They can even improve our character, or at least strengthen our powers of self-control. In spite of the benefits that biomedical enhancements may bring, many people instinctively reject them. Some worry that we will lose something important-our appreciation for what we have or what makes human beings distinctively valuable. To think clearly about enhancement, Buchanan argues, we have to acknowledge that nature is a mixed bag and that our species has many design flaws. We should be open to the possibility of becoming better than human, while never underestimating the risk that our attempts to improve may backfire.
