As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic. Proposals about that have been all over the map.
Edward Witten
As for the British churchman, he goes to church as he goes to the bathroom, with the minimum of fuss and no explanation if he can help it.
Ronald Blythe
Any decision I make is based on myself, and the only person I have to give an explanation to is God.
Solange Knowles
Unemployment is like a headache or a high temperature - unpleasant and exhausting but not carrying in itself any explanation of its cause.

The explanation of the propensity of the English people to portrait painting is to be found in their relish for a Fact. Let a man do the grandest things, fight the greatest battles, or be distinguished by the most brilliant personal heroism, yet the English people would prefer his portrait to a painting of the great deed. The likeness they can judge of; his existence is a Fact. But the truth of the picture of his deeds they cannot judge of, for they have no imagination.
Benjamin Haydon
Everything has a natural explanation. The moon is not a god but a great rock and the sun a hot rock.
Anaxagoras
With the unknown, one is confronted with danger, discomfort, and care; the first instinct is to abolish these painful states. First principle: any explanation is better than none. . . . The causal instinct is thus conditional upon, and excited by, the feeling of fear. The "why?" shall, if at all possible, not give the cause for its own sake so much as for a particular kind of cause -- a cause that is comforting, liberating, and relieving.
Friedrich Nietzsche
On the ordinary view of each species having been independently created, we gain no scientific explanation.
Charles Darwin
