Water,
And you do that all based on completely arbitrary principles, assuming your own superiority.
I have asked a dozen times for a justification of scientific pursuits, for a non-circular and non-self-referential justification of what you are pursuing -- but you, nor any other atheist, has given me one.
They all avoid justification like the plague.
This makes no sense to me. The world is real. People are born, they live they prosper, they suffer, they die. The only thing that provides, and ever has provided, any improvement to the lot of people is science. It began with stone cutting tools for stripping meat off of bones. Then came spearpoints. Fire. Agriculture. Animal husbandry. Wheels. Indoor plumbing.
The justification for everything we do is completely self-referential. What makes you think it is not? And what's the problem with that? To survive, evolution has, in stages, equipped us with curiosity, fear, love, hate, deceit, altruism, intelligence, and every other human trait in just the right balance. So when I exercise my natural curiosity by doing engineering or science, what justification do I need? What is circular about that? When I worry about my children do I need justification?
What we are pursuing is really nothing more than an itch that we need to scratch. What the hell is that colored band in the sky? Just how does it get there? The bible says it's a reminder not to destroy the earth anynmore with water or something, right? Does the bible delve into Rayleigh scattering? Refractive indices? Quantum ElectroDynamics? No? Well, I guess science has its place then. And some side effects of science are:
- Modern medicine
- Average life spans in the 70's to 80's instead of 30's
- Electric power
- Clean drinking water
- Every item in your household (it's all been engineered)
- The ability to feed billions (the church still says go forth and multiply, right? Someones got to feed 'em all. Science to your rescue once again.)
- The internet
- Space stations
- Indoor plumbing
(I'm sure I'll get a corresponding list of all the horrid things science has done now. Spare me.)
So, we're self referential since that's all we have and there's nothing wrong with that. We're not circular unless we want to build a round pool. Any other questions about why we do what we do?
BTW water, I've explained this to you before. Problems with memory? Modern medicine has drugs that can help...
