I can see exactly what PZ is getting at but I didn't take away from the talk the same message! As my better half and I have discussed our disassociation with our faith we have talked about what replaces it. Atheism isn't in and of itself an answer being largely non structured and formless. We've planned to use some of our Sunday's visiting National Trust properties or going for nature walks etc. but even so i find myself struggling to show my children , in a logical way, why critical thinking matters and how it it is useful in the world - there aren't any atheist practice materials or centers of learning. With church it was easy, we had Sunday meetings, books to read, chapters to memorise and lots of social events to reinforce our clan. Now we've left the harbour of faith and ritual the open sea is awe inspiring but at once dangerous and well, huge. I was also thinking about how beautiful some religious buildings are, truly breathtaking and part of me laments the seeming idea that atheism alone cannot inspire this sort of structure.
I think above all it is structure I crave, something to anchor ideas to. Many believing people here detest religion and advocate freeform mystical belief however, that misses the point of the structure, the very building itself isn't what is worshipped but it is somewhere to physically meet. Without the physical that religion brings we are left ... dare I say poorer? If I were ever rich enough to buy and commision a beautiful building for atheistic puposes I think I would, I'd look for some beautiful architectural ideas, I'd maybe use stained windows!, I'd want to host music, literature and poetry shows and I'd put together a regular meeting shedule for children, families and individuals (I of course would keep no membership records or advocate any rules or regulations ) but I would want to provide somewhere to socialise (with a bar and kitchen / food prep area) and share culture.
