Frases John Archibald Wheeler
„We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance.“
— John Archibald Wheeler
Scientific American (1992), Vol. 267.
„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)
„We are participators in bringing into being not only the near and here but the far away and long ago. We are in this sense, participators in bringing about something of the universe in the distant past and if we have one explanation for what's happening in the distant past why should we need more?“

„Time is nature's way to keep everything from happening all at once.“
— John Archibald Wheeler
Wheeler quoted this saying in Complexity, Entropy, and the Physics of Information (1990), p. 10 http://books.google.com/books?id=mdjsOeTgatsC&lpg=PP1&pg=PA10#v=onepage&q&f=false, with a footnote attributing it to "graffiti in the men's room of the Pecan Street Cafe, Austin, Texas". Later publications, such as Paul Davies' 1995 book About Time (p. 236), credited Wheeler with variations of this saying, but the quip is actually much older. The earliest known source is Ray Cummings' 1922 science fiction novel The Girl in the Golden Atom, http://www.gutenberg.org/ebooks/21094 Ch. V: " 'Time,' he said, 'is what keeps everything from happening at once.' "<!-- according to Science-Fiction: The Early Years by Everett F. Bleiler, p. 171 http://books.google.com/books?id=KEZxhkG5eikC&pg=PA171, the novel was a composite of two earlier stories published in 1919 and 1920--> It also appears in his 1929 novel The Man Who Mastered Time. http://books.google.com/books?id=YdZEAAAAYAAJ&q=%22everything+from+happening+at+once%22#search_anchor The earliest known occurrence other than Cummings is from 1962 in Film Facts: Volume 5, p. 48 http://books.google.com/books?id=sr0vAQAAIAAJ&q=%22everything+from+happening+at+once%22.
„It from bit symbolizes the idea that every item of the physical world has at bottom — at a very deep bottom, in most instances — an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes-no questions and the resistering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe.“

„Of all heroes, Spinoza was Einstein's greatest. No one expressed more strongly than he a belief in the harmony, the beauty, and most of all the ultimate comprehensibility of nature.“

„Today I think we are beginning to suspect that man is not a tiny cog that doesn’t really make much difference to the running of the huge machine, but rather that there is a much more intimate tie between man and the universe than we heretofore suspected…The physical world is in some deep sense tied to the human being.“
— John Archibald Wheeler
As quoted in by Ken Wilber in Quantum Questions: Mystical Writings of the World's Great Physicists (2001) Shambhala, .
„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
