Dont worry, I know what you mean

.
But no, I actually dont. I think love, hope, trust, human emotions, intelligence, nature and reality in general are all amazing in and of themselves. Like I said, I do not think that learning about reality lessens these things in any way. In many ways it makes them more amazing.
I know science must be as un-baised as possible, but that is no reason for it to be cold. Science gives us medicine (this goes as far back as learning what plants help heal a wound), architecture, technology. Plus, my favorite (art student here), science and art are getting more and more melded every day. Thats far from cold and sterile.
And even though our brains are effected by our genes, environment, and chemicals, our brains are us. To be more precise, we are what our brains does. So even though my brain is effected, all these changes, subtle, still are within my brain, and those changes then are me. This one I`m having a little trouble saying.... well, it`s the morning. So it all depends how you define free will. Most biologcal urges can be overridden, sociological pressure can be ignored. There are a million possible things I can do today if I choose, and my biological makeup does not stop me from doing any. (It might stop me from, say, stepping in front of a bus, but I do not really have a problem with that. I could override such a desire to not step in front of a bus, but I choose not to. Free Will). I could go on a tangent about how some religions, if they were true, would really make us have no free will, but I`ll refrain from that.
All in all, I think science is really neat, and reality is more amazing and awe inspireing than any of us humans can make up.
There, I hope that answered your question for you!
