And Dawkins said: "Non fiat sententiam."
I heard Richard Dawkins say something most interesting on the radio the other day. He said that the universe does not owe us meaning, that humans often believe things because they'd be "nice." He called this a weakness in the human psyche (referring to many people's belief in a higher power or universal purpose because "they couldn't bear to live in a world without it"). Although I thought his arguments against God were spot-on and extremely insightful, I have to disagree with his assessment of this perceived "weakness."
I think that, many times, when people believe things because it would make them happier, it's often resulted in humans vastly exceding their previous bounds. Sure there have been negative consequences due to the fuzzy nature of humanity's hope-reality divide. Yet, I would postulate that our slight tendancy for being optimistically deluded has helped our species not see just how lost, how fragile, how slight, and how ultimately random our existence is. It's helped us believe in our own ability to change and thrive, even when we should've known how bad the odds were. And I think it will help us in the present and future when we have to believe in our own survival despite the limited carrying capacity and eventual collapse of our current ecosystem.
I think humanity's evolution of some rose-colored glasses was a veritable competitive edge. Wouldn't a creature who often irrationally believes in itself, in its own abilities and fortunes beat out a similarly matched, but more rationally-brained creature? But, in good human fashion, that's something I'd like to believe.
