" Science and religion, though complementary, explore different spheres: Science can observe and measure only physical causes; religion concerns itself with the spiritual realm. Science can tell us what things are made of and how things work, but not the why. It can tell us that man is made of this and that, and that muscles work this way and not that way, but it cannot tell us why we exist in the first place, what our lives are for. Therefore, science cannot give us the principles we need to guide our actions. We must look elsewhere for those. "
