John Archibald Wheeler quotes

Time is what prevents everything from happening at once. (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
In any field, find the strangest thing and then explore it.
John Archibald Wheeler
There are many modes of thinking about the world around us and our place in it. I like to consider all the angles from which we might gain perspective on our amazing universe and the nature of existence.
John Archibald Wheeler
Spacetime tells matter how to move; matter tells spacetime how to curve.
John Archibald Wheeler
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.
John Archibald Wheeler
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
... we can afford many mistakes in the search. The main thing is to make as fast as possible.
John Archibald Wheeler
In order to more fully understand this reality, we must take into account other dimensions of a broader reality.
John Archibald Wheeler
To hate is to study, to study is to understand, to understand is to appreciate, to appreciate is to love. So maybe I'll end up loving your theory.
John Archibald Wheeler
The question is-what is the question? (John Archibald Wheeler)
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
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?
John Archibald Wheeler
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.
John Archibald Wheeler
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.
John Archibald Wheeler
If I had to confess, under torture, right now, what I think the simple idea is, I would say it's that we ourselves generate the world, the world is self-generated, but it may well be absolutely wrong.
John Archibald Wheeler
If you haven't found something strange during the day, it hasn't been much of a day.
John Archibald Wheeler
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
Behind it all is surely an idea so simple, so beautiful, that when we grasp it - in a decade, a century, or a millennium - we will all say to each other, how could it have been otherwise? How could we have been so stupid?
John Archibald Wheeler
No phenomenon is a real phenomenon until it is an observed phenomenon.
John Archibald Wheeler
It is my opinion that everything must be based on a simple idea. And it is my opinion that this idea, once we have finally discovered it, will be so compelling, so beautiful, that we will say to one another, yes, how could it have been any different. (John Archibald Wheeler)
I like to think that someone will trace how the deepest thinking of India made its way to Greece and from there to the philosophy of our times.
John Archibald Wheeler
What we think of as smooth simple space is really a wiggly business.
