Because science has introduced the world to a great number of achievements in medicine, technology, and numerous other factors, people have grown to place a high value on the teachings of science. This is a good thing. No one can make a coherent argument against the value of the great number of lives that have been saved due to the scientific advances in medicine. The great problem arises, though, when science becomes not just one of the many ways that we acquire knowledge, but the only way; that if we cannot test something scientifically, it cannot be true. This is exactly the belief that sways people to abandon any information that leads to supernatural beliefs. I must point out here, though, that the core belief (that only things that can be tested and proven by scientific means) cannot itself be tested by science. Even though one might attempt to prove the statement philosophically, philosophy is outside of the realm of science so, by definition, the philosophical defense cannot be accepted.
