It is impossible to imagine the universe run by a wise, just and omnipotent God, but it is quite easy to imagine it run by a board of gods. If such a board actually exists it operates precisely like the board of a corporation that is losing money.H.L. Mencken
Why assume so glibly that the God who presumably created the universe is still running it?

This is true, for example, of most universities, and of all great newspapers.H.L. Mencken
