It's sad that Ramsey died so young. It's also sad that it has taken nearly a century for the wider culture/society to begin embracing the concept of 'degrees of belief' in any significant way (I could definitely be wrong, but it seems to me that it is being embraced more). A number of public intellectuals have said probabilistic reasoning is king for the forseeable future (of course, such reasoning is a bit different from the ground being covered by degrees of belief). I know some professors who are even moving away from the emphasis on deductive reasoning in introductory logic courses.
