My obligation is to the people of BC, and I will defend that until I am no longer premier. - John Horgan

Kuhn's recognition that science might cease—leaving us with what Charles Sanders Peirce had defined as the "truth" about nature—made it even more imperative for Kuhn than for Popper to challenge science's authority, to deny that science can ever arrive at absolute truth. "The one thing I think you shouldn't say is that now we've found out what the world is really like," Kuhn said. "Because that's not what I think the game is about."

Over the last few decades, physics in the grand mode practiced by Hawking and Rees has become increasingly disconnected from empirical evidence. Proponents of string and multiverse models tout their mathematical elegance, but strings are too small and multiverses too distant to be detected by any plausible experiment.

Our descendants will learn much more about nature, and they will invent gadgets even cooler than smart phones. But their scientific version of reality will resemble ours, for two reasons: First, ours… is in many respects true; most new knowledge will merely extend and fill in our current maps of reality rather than forcing radical revisions. Second, some major remaining mysteries—Where did the universe come from? How did life begin? How, exactly, does a chunk of meat make a mind?—might be unsolvable.
