"While we have all the flaws concomitant with being children of chance, we also have an advantage: we're free. There is no cosmic fiddler. There is no domineering father in the sky who has a mission for us, who decreed at our birth that there is something we must do with our lives, who has slotted you into one specific role without your consent. You are not driven by an arbitrary external purpose, and you should find the idea of such a daily dictator of every detail of your existence abhorrent to an extreme.
It's a real mystery to me why anyone would find the deterministic slave-philosophy of Rick Warren at all appealing or consoling, especially since the evidence all says that it is wrong, as well. There must be something some people find pleasant in surrendering responsibility to an imaginary scapegoat.
Personally, I appreciate the fact that I'm a combination of traits, some lucky and some unlucky, that are mine and not the product of the whims of some puppetmaster. I'll make of them what I can and what I will, and who I am is my responsibility and to my credit or blame."
