I lament the loss of useful philosophers that predated modern physics—Immanuel Kant, David Hume, Kurt Gödel, Bertrand Russell, Ernst Mach. Not coincidentally, the transition to uselessness began when our experiments revealed aspects of the universe that no longer followed what anyone would call common sense. The tenets of relativity and quantum mechanics, for example. The day a philosopher’s conversation on the “meaning of meaning” offers useful insight to the next cosmic discovery, I will be happy to revise my views.
