„Not how the world is, but that it is, is the mystery.“

„Is there any more mysterious idea for an artist than the conception of how nature is mirrored in the eyes of an animal? How does a horse see the world, or an eagle, or a doe, or a dog?“

—  Juliet Marillier New Zealand fiction writer 1948

„We do not have a complete and satisfying knowledge of the world. We are reduced to the simple conclusion that everywhere in the world there is life like ourselves and that all life is shrouded in mystery. A true acquaintance with the world consists in being filled with a sense of the mystery of existence and life. This mystery becomes only more mysterious with every advance in scientific research. To be filled with the mystery of life is like that which is called in the language of mysticism the "wise ignorance," an ignorance which is nonetheless knowledge of the essential.“

„One may say "the eternal mystery of the world is its comprehensibility."“

—  Albert Einstein German-born physicist and founder of the theory of relativity 1879 - 1955

From the article "Physics and Reality" (March 1936), reprinted in Out of My Later Years (1956). The quotation marks may just indicate that he wants to present this as a new aphorism, but it could possibly indicate that he is paraphrasing or quoting someone else — perhaps Immanuel Kant, since in the next sentence he says "It is one of the great realizations of Immanuel Kant that the setting up of a real external world would be senseless without this comprehensibility."
Other variants:
The eternally incomprehensible thing about the world is its comprehensibility.
In the endnotes to Einstein: His Life and Universe by Walter Isaacson, note 46 on p. 628 http://books.google.com/books?id=cdxWNE7NY6QC&lpg=PP1&pg=PA628#v=onepage&q&f=false says that "Gerald Holton says that this is more properly translated" as the variant above, citing Holton's essay "What Precisely is Thinking?" on p. 161 of Einstein: A Centenary Volume edited by Anthony Philip French.
The most incomprehensible thing about the world is that it is comprehensible.
This version was given in Einstein: A Biography (1954) by Antonina Vallentin, p. 24, and widely quoted afterwards. Vallentin cites "Physics and Reality" in Journal of the Franklin Institute (March 1936), and is possibly giving a variant translation as with Holton.
The most incomprehensible thing about the world is that it is at all comprehensible.
As quoted in Speaking of Science (2000) by Michael Fripp
The eternal mystery of the world is its comprehensibility … The fact that it is comprehensible is a miracle.
As quoted in Einstein: His Life and Universe by Walter Isaacson, p. 462 http://books.google.com/books?id=cdxWNE7NY6QC&lpg=PP1&pg=PA462#v=onepage&q&f=false. In the original essay "The fact that it is comprehensible is a miracle" appears at the end of the paragraph that follows the paragraph in which "The eternal mystery of the world is its comprehensibility" appears.

„We manipulate what is available on the surface of the world; we must also stand in awe before the mystery of the world.“

—  Abraham Joshua Heschel Polish-American Conservative Judaism Rabbi 1907 - 1972

Forrás: Who Is Man? (1965), Ch. 5<!-- The sense of the ineffable, p. 88 -->
Kontextus: The world presents itself in two ways to me. The world as a thing I own, the world as a mystery I face. What I own is a trifle, what I face is sublime. I am careful not to waste what I own; I must learn not to miss what I face.
We manipulate what is available on the surface of the world; we must also stand in awe before the mystery of the world. We objectify Being but we also are present at Being in wonder, in radical amazement.
All we have is a sense of awe and radical amazement in the face of a mystery that staggers our ability to sense it.
