Hello, A friend of mine has a very bitter attitude towards science. We've had numerous arguments and his main reason for this bitterness is that science is just another faith system, kinda like a religion. I failed to convince him that unlike faith, science's strength is the fact that it is backed up by experiments, but nonetheless he always managed to defend his point. I know that our argument is purely formal and more of a play on words than anything else, but I would still like to prove my point. So his claim is that I believe the different theories of physics just because I go to class and my professors or my text books tell me so, which is no different than going to church and believing what a preacher says there. But I said that unlike the church, I am able to check what I am being told through scientific experiments. So he asked me: Do you believe in the theory of gravity and I said yes and told him that I can give him a lot of experimental evidence. So he asked me, well what if someone tells you that an object falls downward because it is god's will, then it is very easy to construct a hypothesis that could be tested with millions of experiements and every time it will prove that the hypothesis that god's will makes objects fall is always correct ! I argued saying that in this case all that you've done was give gravity a different name (i.e. god's will)...but you can find other situations where this reasoning doesn't work too good. How can you argue against that?
