science: a false mistress?

I'm a little worried about science. This has come out of some discussions lately with my friend ben. we both have degrees in philosophy and haven't taken a science class for about four years, so the conclusions that came out of our discussion should be taken, I belive, iwht a grain of salt. That being said, I think modern science is terrifyingly dangerous. I think this because whenever we talk about how we know or percieve or behave, we automatically want to go to the physiological explaination of thse things. Once we find that explaination, we stop and think ourselves wise. Scientific findings about the physical world masquerade as complete explainations, as holistic answers, and I fear if I and we are not careful, they will gorw so large as to blot out the stars and all we shall see is the unreal cosmos of material interaction and lose sight of all that is not matter. It looks so much like truth! and it is true, usually, as far as it goes. But God save me from its snares: its experiments, its control groups, its data and its polls. Tie me to the wall of uncertainly before I follow it down the raid to a shadowland of seeming sense!
