Our nations, cultures, politics, genders, occupations, interests, and so on differ widely. However, we are generally “in sync” with one another because we share a worldview that is free from supernatural and mystical elements. We are set apart in a broad sense from those who have worldviews that embrace such elements, whether entities such as deities, or forces, or both. Most of us find our naturalistic worldview regarding “ultimate beliefs” marginalized in the society in which we live (perhaps utterly disparaged, or even proscribed). Our common interest is to work to in varied ways to change this situation for the better.
Does this describe you? Then you can be a "Bright". I think I am. So are some of the best minds in the world: Richard Dawkins, Daniel Dennet, James Randi, Steven Pinker among others. Are you one too?
