John Archibald Wheeler Quotes

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.

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.

... we can afford many mistakes in the search. The main thing is to make as fast as possible.

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.

We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance.

What we think of as smooth simple space is really a wiggly business.

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?

For all our everyday experience, the geometry of space is smooth and flat. But as we examine it more closely, it must show oscillations. And still more closely, it must show foam, a foam-like structure. And that means that down at the very smallest distances, this idea of before and after really lose their meaning.

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 registering 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.

Space tells matter how to move
Matter tells space how to curve

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.

The question is—what is the question?
