I agree with DKV that much of science is contingent upon faith( faith = "confident BELIEF or TRUST in persons, ideas, or things"). Faith in theories (theory = "systematically organized knowledge, esp. a set of assumptions or statements devised to explain a phenomenom or class of phenomena") exemplifies this contigency. You can not have science without some semblence faith. One silly example I like is someone who says that their "senses" tell them what is real. Then I say does the Earth revolve around the sun or does the sun revolve around the Earth? Your eyes see the sun move across the sky. But science tells us a different story. I have not travelled to outerspace to "see" the Earth travel around the sun and yet I "believe" in the science that contradicts my senses. I have faith that the Earth travels around the sun and I have faith that the sun will rise tommorow
