"One of the curious features of modern physics is that in spite of its overwhelming success in explaining a vast range of of physical phenomena from quark to quasar, it fails to give us a single metaphor for how the universe really works."

“Though today's quantum theory shows no sign of weakness, someday it may collapse.”

“The pragmatist regards any theory as a mere mathematical machine for generating numbers which he then compares with experiment. A pragmatist is concerned with results, not reality. The pragmatist refuses on principle to speculate about deep reality, such a concept being meaningless from his point of view. Pragmatism is an intelectually safe but ultimately sterile philosophy.”

“Physicists, for all their odd notions, are basically a conservative lot.”

“Although mathematics originates in the human mind, its remarkable effectiveness in explaining the world does not extend to the mind itself. Psychology has proved unusually resistant to the mathematization that works so well in physics.”

“Legendary King Midas never knew the feel of silk or a human hand after everything he touched turned to gold. Humans are stuck in a similar Midas-like predicament: we can't directly experience the true texture of reality because everything we touch turns to matter.”

“The entire visible universe, what Bishop Berkley called "the mighty frame of the world," rests ultimately on a strange quantum kind of being no more substantial than a promise.”
