Governor Mitt Romney has yet to persuade the religious conservatives in his party that he is fit to be President of the United States. However, he could probably appease the Republican base and secure his party’s nomination if he made the following remarks prior to the South Carolina Primary:
Lawrence M. Krauss is a renowned cosmologist, popularizer of science, and director of the Origins Project at Arizona State University. He is the author of more than 300 scientific publications and 8 books, including the bestselling The Physics of Star Trek. His interests include the early universe, the nature of dark matter, general relativity and neutrino astrophysics. He is also a friend and an advisor to my nonprofit foundation, Project Reason. Lawrence generously took time to answer a few questions about his new book, A Universe from Nothing.
The moment it was announced that Christopher Hitchens was sick with cancer, eulogies began spilling into print and from the podium. No one wanted to deny the possibility that he would recover, of course, but neither could we let the admiration we felt for him go unexpressed. It is a cliché to say that he was one of a kind and none can fill his shoes—but Hitch was and none can. In his case not even the most effusive tributes ring hollow. There was simply no one like him.
One of the joys of living in a world filled with stupidity and hypocrisy was to see Hitch respond. That pleasure is now denied us. The problems that drew his attention remain—and so does the record of his brilliance, courage, erudition, and good humor in the face of outrage. But his absence will leave an enormous void in the years to come. Hitch lived an extraordinarily large life. (Read his memoir, Hitch-22, and marvel.) It was too short, to be sure—and one can only imagine what another two decades might have brought out of him—but Hitch produced more fine work, read more books, met more interesting people, and won more arguments than most of us could in several centuries.
Daniel Kahneman is an extraordinarily interesting thinker. As a psychologist, he received the 2002 Nobel Prize in Economics for his work with Amos Tversky on decision-making. Here is what Steven Pinker, my previous interview subject, recently wrote about him:
Daniel Kahneman is among the most influential psychologists in history and certainly the most important psychologist alive today. He has a gift for uncovering remarkable features of the human mind, many of which have become textbook classics and part of the conventional wisdom. His work has reshaped social psychology, cognitive science, the study of reason and of happiness, and behavioral economics, a field that he and his collaborator Amos Tversky helped to launch. The appearance of Thinking, Fast and Slow is a major event.
Kahneman was kind enough to take time out of a very busy book tour to answer a few of my questions.

As a teenager, I once had an opportunity to fly in a police helicopter over a major American city. Naively, I thought the experience might be uneventful. Perhaps there would be no crime between 8:00 and 10:00 p.m. on a Saturday night. However, from the moment we were airborne, there was a fresh emergency every fifteen seconds: Shots fired… rape in progress… victim stabbed…It was a deluge. Of course, the impression this left on me was, in part, the result of a sampling bias: I was hearing nothing but incident reports from a city of 4 million people, most of whom would never encounter violence directly. (No one calls the police to say “Everything is still okay!”) Yet it was uncanny to discover the chaos that lurked at the margins of my daily routine. A few minutes from where I might otherwise have been eating dinner, rapes, robberies, and murders were in progress.

The universe is filled with physical phenomena that appear devoid of consciousness. From the birth of stars and planets, to the early stages of cell division in a human embryo, the structures and processes we find in Nature seem to lack an inner life. At some point in the development of certain complex organisms, however, consciousness emerges. This miracle does not depend on a change of materials—for you and I are built of the same atoms as a fern or a ham sandwich. Rather, it must be a matter of organization. Arranging atoms in a certain way appears to bring consciousness into being. And this fact is among the deepest mysteries given to us to contemplate.
Many readers of my previous essay did not understand why the emergence of consciousness should pose a special problem to science. Every feature of the human mind and body emerges over the course development: Why is consciousness more perplexing than language or digestion? The problem, however, is that the distance between unconsciousness and consciousness must be traversed in a single stride, if traversed at all. Just as the appearance of something out of nothing cannot be explained by our saying that the first something was “very small,” the birth of consciousness is rendered no less mysterious by saying that the simplest minds have only a glimmer of it.
