As an atheist and humanist and an Ex JDub I have been involved in many conversations with theists (both here and in RL) about the primary differences between our worldviews. While the belief vs evidence debate will never end, I am always confused and hurt by the occasional implication that because I use the scientific principle to form my world view I somehow lack wonder, feelings or "heart". On the other side of the coin I am always angered when someone with a theist world view is accused of being a non-thinker or somehow lacking intelligence.
I came across a talk on TED that moved me to post a link. I think that Jill Bolte Taylor's experience has taught me a little bit about why the differences exist and maybe insight into how we can move closer together.
Enjoy..trust me its worth a view.
