You can’t see or measure the love you have for a child or friend, but it is real and true. It changes lives. You can’t see or measure guilt or forgiveness or joy, but they are still real and true. They change lives. So to say, ‘If I can’t see or measure it, it’s not real or true’ is to assert that your own senses are the only gauge of reality. It’s like you’re an investigator at the scene of a crime and you’ll only accept finger prints as legitimate evidence. So immediately, you dismiss the testimony of credible eye witnesses; you dismiss any other non-forensic clues already in the room; and you even dismiss exploring the motives of various potential suspects. Before you even start, you’re limiting your perspective. The same is true for materialists. They’re limiting their perspective before they even start. A person who thinks this way would hear about a potential “miracle” and tell you that it didn’t really happen right out of the gate. Why? Because it can’t be measured and doesn’t fit with what they already think they know about their interpretation of reality. But a true scientist would study the evidence, and then observe (a) that there is either a measurable explanation, or (b) that in the absence of a measurable explanation, something may have happened which we simply can’t yet explain. So what a lot of people call “science” isn’t actually science. It’s a way of understanding reality—a philosophical outlook—called “materialism.” — Matthew Ruttan (from, Are science and faith opposites?)
