that wasn't my quote, it was R.E's - sorry, not up to speed on this

but I agree that we'll either self destruct or not. I choose to believe (and this is a question of belief, I think) that we won't, for the simple fact of our potential for intelligent thought. The Earth has given all it's life a start, with the Will to Live. Evolution has enabled survival of the fittest, but then there is a step after survival, which is living! That's what we need to work on.
