When I think of people I know who are manifestly superb thinkers, Pinker and Murray are always near the top of the list for clarity, elegance, power, and precision of mind.
Here`s a bit from an interview I did with Pinker to promote his book The Blank Slate that shows his command:
Q: Aren`t we all better off if people believe that we are not constrained by our biology and so can achieve any future we choose?
A: People are surely better off with the truth. Oddly enough, everyone agrees with this when it comes to the arts. Sophisticated people sneer at feel-good comedies and saccharine romances in which everyone lives happily ever after. But when it comes to science, these same people say, “Give us schmaltz!” They expect the science of human beings to be a source of emotional uplift and inspirational sermonizing.
