The universe is everything, to say something is outside it is to say it doesn't exist. No one knows if there is a creator, but no one knows if our brains are really tripping hedgehogs on another planet, and the grey matter is just the part that extrudes into this world. You see, there is an infinite number of things we could say we don't know exist.
I see that the vast majority of processes in the observable universe are not intelligent. Intelligence is a quality employed by a small number of living animals that either hunt or are hunted, and so evolved the need to anticipate danger in order to avoid it.
Furthermore, the living things, which are the only things that seem to require a supernatural explanation, do not exhibit the qualities of designed things.
The world order in Brave New World depended on classes of people with varying degrees of ignorance, supported by constant brainwashing, propaganda, and above all, faith.
I am only saying that I do not believe that our senses can truly sense EVERYTHING within the universe; our handicap is that we can only sense the physical.
What would be the qualities of designed things? Besides, did I say that an intelligent entity guided us along? No. I said it is possible, and not ridiculous, that some sort of intelligence had led to the creation of the universe (or influenced it); not necessarily that that intelligence is supernatural, nor that it governs us.
Again, is it irrational to think, for instance, that our universe may be some experiment by a greater intelligence? That we are, right now, being examined by a scientist?
Perhaps ridiculous, but we are not explaining something WITHIN OUR WORLD; we are attempting to explain where all that we know, has come from.
I disagree; remember, in Brave New World faith was discouraged; a man making something of himself was LIKEWISE discouraged.
What I mean is that in an atheist society, I don't actually think the people would be as in Brave New World, but rather have no more "purpose" than in brave new world. In Brave New World what was the point of living?
People did not do anything for themselves
In a moderately faithful society, I think the benefit is that encouragement to do something for yourself, to reach something HIGHER, and to overall, have that faith and unity and common ground with society.
