Whatever it was that did take, remains, for now, nameless.

Is it important for you to have a name for it? I had not heard of the Brights movement, but I was familiar with the concept of naturalism, which seems to fit the view you articulate above, but may not be a meaningful term for you. Coming from a mixed family of self-identified, primarily Jewish atheists and agnostics (and one pantheist), I am not uncomfortable with the language, but it is more useful for me to say that my universe is not oriented with relation to faith, which in keeping with the previous terms of the conversation is akin to the way in which I am comfortable identifying as bisexual, but the most accurate thing is that I am interested in people.
