Jorge Luis Borges (1899-1986), Argentinewriter. Borges said:
"Being an agnostic means all things are possible, even God, even the Holy Trinity. This world is so strange that anything may happen, or may not happen. Being an agnostic makes me live in a larger, a more fantastic kind of world, almost uncanny. It makes me more tolerant."
"Most students ... wish to know whether I believe in the existence of God or in immortality, and if so why. They regard it impossible to leave these matters unsettled – or at least extremely detrimental to religion not to have the basis of such conviction. Now for my part I do not find it impossible to leave them open.... I can describe myself as no ardent theist or atheist."

↑Russell said: "As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic, because I do not think that there is a conclusive argument by which one prove that there is not a God. On the other hand, if I am to convey the right impression to the ordinary man in the street I think I ought to say that I am an Atheist... None of us would seriously consider the possibility that all the gods of Homer really exist, and yet if you were to set to work to give a logical demonstration that Zeus, Hera, Poseidon, and the rest of them did not exist you would find it an awful job. You could not get such proof. Therefore, in regard to the Olympic gods, speaking to a purely philosophical audience, I would say that I am an Agnostic. But speaking popularly, I think that all of us would say in regard to those gods that we were Atheists. In regard to the Christian God, I should, I think, take exactly the same line."
