At a time when the Enlightenment is under attack from without and within, I bring together two of the most thoughtful defenders of progress and reason, for their first ever public dialogue. Steven Pinker is the Johnstone Professor of Psychology at Harvard University. I think of him as providing the strongest empirical defence of the Enlightenment (as seen in his book Enlightenment Now). David Deutsch is a British physicist at the University of Oxford, and the father of quantum computing. I think of him as having produced the most compelling first principles defence of the Enlightenment (as seen in his book The Beginning of Infinity).
