Although I would agree, anybody who associates personality and creativity with some kind of universal entity is likely deluded; faith, never the less, has a very real and relevant function in our lives.
My reasoning stems from the fact that, frankly, I can't know everything. I don't believe anybody can. But if omniscience is out of the question, then what do I fill the holes in my knowledge with? Simple answer, assumptions. And an assumption is merely taking a position of faith while I figure all the other stuff out--I may need to come back and change my assumptions after I've learned more, but it is an exercise in faith that got me over the hump.
Furthermore, though the God of my fathers' is certainly dead to me, I yet sense divinity and holiness in our universe. Now, if we can agree that some things are sacred, and also, that we all must at some point rely on faith, then I'll accept any definition of secular humanism you wish to give me. But let us not be reciprocal fundamentalists about it! Fundamentalism is not a good thing from either the believers' or the unbelievers' camp. There will always be room for liberal religion and its quirkiness in the world I dream of.
