@JLNobody,
Funny that you ask, since the idea for the headline came from his statement that philosophy is dead, since it has failed to keep up with the developments in modern science, particularly physics.
I sometimes think that it is strange that we can think of Stephen Hawking as a cripple. He is perhaps one of the most brilliant men alive, but he has some severe physical defects. On the other hand there are people who can barely do their multiplications and who are incapable of the simplest rational thought, and yet they are considered normal and healthy just because there is nothing that is obviously physically wrong with them...
