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).

Bayesianism, the doctrine that it's always rational to represent our beliefs in terms of probabilities, dominates the intellectual world, from decision theory to the philosophy of science.
