“There is no meaning to space that is independent of the relationships among real things of the world. …Space is nothing apart from the things that exist. …If we take out all the words we are not left with an empty sentence, we are left with nothing.”

“Overcome space, and all we have left is Here. Overcome time, and all we have left is Now.”

Richard Bach book Jonathan Livingston Seagull

Source: Jonathan Livingston Seagull (1970)
Context: If our friendship depends on things like space and time, then when we finally overcome space and time, we've destroyed our own brotherhood! But overcome space, and all we have left is Here. Overcome time, and all we have left is Now. And in the middle of Here and Now, don't you think that we might see each other once or twice?

“There is no such thing as an empty space or an empty time. There is always something to see, something to hear. In fact, try as we may to make a silence, we cannot.”

After his father died he carried his life more gently & left an empty space for the birds & other creatures.”

“You loved so hard and hoped so much and then you ended up with nothing. Children who no longer needed you. A husband who no longer wanted you. Nothing left but you, alone, and empty space.”

“We might have a chance now to rebuild it all with what we have left. We might have learned that we can exist only as a part of nature, not apart from nature.”

“Death is not an easy thing for anyone to understand, least of all a child, but every life shall one day end. But as long as we are alive, as long as we are together, as long as two of us are left, and remember him, nothing in the world can take him from us. His body can be taken, but not him.”

William Saroyan book The Human Comedy

The Human Comedy (1943)
Context: Death is not an easy thing for anyone to understand, least of all a child, but every life shall one day end. But as long as we are alive, as long as we are together, as long as two of us are left, and remember him, nothing in the world can take him from us. His body can be taken, but not him. You shall know your father better as you grow and know yourself better. He is not dead, because you are alive. Time and accident, illness and weariness took his body, but already you have given it back to him, younger and more eager than ever. I don't expect you to understand anything I'm telling you. But I know you will remember this — that nothing good ever ends. If it did, there would be no people in the world — no life at all, anywhere. And the world is full of people and full of wonderful life.

“I just want to explain what I mean when I say that we should try to hold on to physical reality.
We are … all aware of the situation regarding what will turn out to be the basic foundational concepts in physics: the point-mass or the particle is surely not among them; the field, in the Faraday-Maxwell sense, might be, but not with certainty. But that which we conceive as existing ("real") should somehow be localized in time and space. That is, the real in one part of space, A, should (in theory) somehow "exist" independently of that which is thought of as real in another part of space, B. If a physical system stretches over A and B, then what is present in B should somehow have an existence independent of what is present in A. What is actually present in B should thus not depend the type of measurement carried out in the part of space A; it should also be independent of whether or not a measurement is made in A.
If one adheres to this program, then one can hardly view the quantum-theoretical description as a complete representation of the physically real. If one attempts, nevertheless, so to view it, then one must assume that the physically real in B undergoes a sudden change because of a measurement in A. My physical instincts bristle at that suggestion.
However, if one renounces the assumption that what is present in different parts of space has an independent, real existence, then I don't see at all what physics is supposed to be describing. For what is thought to be a "system" is after all, just conventional, and I do not see how one is supposed to divide up the world objectively so that one can make statements about parts.”

“The meaning of the Sabbath is to celebrate time rather than space. Six days a week we live under the tyranny of things of space; on the Sabbath we try to become attuned to holiness in time. It is a day on which we are called upon to share in what is eternal in time, to turn from the results of creation to the mystery of creation; from the world of creation to the creation of the world.”

Abraham Joshua Heschel (1907–1972) Polish-American Conservative Judaism Rabbi
