Religion is the vision of something which stands
beyond, behind and within the passing flux of immediate things;
something which is real, and yet waiting to be realized;
something which is a remote possibility, and yet the greatest of present facts;
something that gives meaning to all that passes, and yet eludes apprehension;
something whose possession is the final good, and yet is beyond all reach;
something which is the ultimate ideal, and the hopeless quest.
Alfred North Whitehead, Science and the Modern World
