Are you a bright? Do you know what the question is asking?
These days "bright" is like "gay", an ordinary noun pressed into service to paper over an earlier, less-flattering term. Being a gay sounds better than being a homosexual, more normal, less scientific, more acceptable. And being a bright sounds better than being an atheist or agnostic for the same reasons. A significant number of people are coming "out of the closet" and admitting they are brights.
Richard Dawkins and Daniel Dennett are brights. They just happen to be two of my very favorite authors, philosophers, avowed Darwinists, and opposed to mysticism in any form.
Yeah, I'm a bright. I believe in a naturalistic world view. I believe everything can be explained rationally, logically, and scientifically, without resort to "magic". (Arthur C. Clarke famously noted "any sufficiently advanced technology is indistinguishable from magic". I would add, "any sufficiently complex scientific process is indistinguishable from magic".) I am excited by science, the relentless pursuit of truth, piling fact upon fact, testing hypothesis, gradually revealing underlying simplicity, building understanding.
So, I'm a bright. Does this mean I don't believe in God? The quick answer is no, it doesn't mean that. The slow answer is a question; "what do you mean by God"? If you mean a Judeo-Christian God, no, I don't believe in that God. If you mean a Muslim Allah, or the concept of Buddha, no, sorry, not for me. Those Gods are concepts invented by people thousands of years ago to explain the unexplainable. My world view doesn't require a God to explain anything. But my world view does have room for spirituality, for feelings, for emotion. For beauty. For symmetry. For simplicity and elegance. For science. That is my god (and it doesn't require a capital letter, either).
For some, replacing an all-powerful, all-good, all-knowing, all-everything deity with "mere" science is horrible. That's okay, I don't ask anyone to think as I do, and I can accept that your reality (as perceived by you) is different from my reality. But for me, I can't imagine anything more beautiful.
