“I had the good fortune of having my first and only heart attack last January … I call it good fortune because it taught me that there's a limited amount of time left and I better concentrate on one thing: How come existence? How come the quantum? Maybe those questions sound too philosophical, but maybe philosophy is too important to be left to the philosophers.”

John Archibald Wheeler

As quoted by Amanda Gefter (from the symposium in honor of Wheeler's 90th birthday) [Trespassing on Einstein's lawn: a father, a daughter, the meaning of nothing, and the beginning of everything, 2014, https://books.google.com/books?id=NUMkAAAAQBAJ]

“Is the very mechanism for the universe to come into being meaningless or unworkable or both unless the universe is guaranteed to produce life, consciousness and observership somewhere and for some little time in its history-to-be? The quantum principle shows that there is a sense in which what the observer will do in the future defines what happens in the past—even in a past so remote that life did not then exist, and shows even more, that 'observership' is a prerequisite for any useful version of 'reality.”

John Archibald Wheeler

As quoted by Paul Davies, Other Worlds (1980)

Life , History , Reality , Sense

“Of all obstacles to a thoroughly penetrating account of existence, none looms up more dismayingly than “time.” Explain time? Not without explaining existence. Explain existence? Not without explaining time. To uncover the deep and hidden connection between time and existence, to close on itself our quartet of questions, is a task for the future.”
