This is a follow up to my last post, The Funny Thing about Science. There, I talked about how the fundamental presupposition behind science is self defeating. Scientists – without a shred of evidence – accept a worldview that requires them to not accept anything without evidence. I still laugh every time I think about it. Before I get into my own worldview, let's consider a couple of other things about the worldview of secular science.
Scientists (both Christian and secular scientists) have done a pretty good job in describing processes. They have learned to apply physical laws in practical ways. Take our first trip to the moon, for example. We had to create a method to leave earth's atmosphere, land on the moon, lift off the moon, and return the astronauts safely to earth. A million and one things had to be taken into consideration but here's one thing I've not heard discussed: how did the scientists know that the physical laws we understand on earth would be the same on the moon? We had never been to the moon before. We've never observed or tested physical laws there. They merely assumed they would be the same.
Scientists never really talk about it but they don't have an explanation for the origin of physical laws. Where did gravity come from, for example? They don't know; they just know that it exists. It must have poofed itself into existence. If they don't know where physical laws came from, what rational reason do they have to expect them to continue to operate in a predictable way? Some might say that since the laws have always behaved in predictable ways they expect them to continue behaving in predictable ways. This is about as logical as saying, “Well, I've never died before so I don't expect to die in the future.” The truth is, they have no logical reason to believe physical laws will continue behaving in predictable ways. They merely assume they will. If physical laws poofed themselves into existence, there is no rational reason to believe they will always operate in predictable ways.
Along those lines, how do scientists know that physical laws operate the same everywhere? We've not been everywhere to observe or test them. Ultimately, scientists have to assume they do. It's another one of those faith-like things that scientists practice.
Finally, how can scientists have confidence in their own senses as they make observation? After all, if evolution is true, then our brains are simply the products of millions of years of mutation and selection and our thoughts are merely chemical reactions in our brains. Even our memories could not be relied upon. Yet scientists assume their senses are reliable.
Uniform laws, predictability, and repeatability are all necessary in science. Scientists assume these things are true but really have no reason to expect them according to their own theory.
Now, here's the cool thing about Christianity. I have a worldview that God created us and has given us His revealed word – the Bible. The Bible affirms itself to be true – unlike the secular worldview which contradicts itself. The Bible says that God not only created the universe but He also sustains it. Since God is everywhere, I have a rational reason to believe that His physical laws will be the same everywhere. Since God doesn't change, I have a rational reason to believe His physical laws will always continue to operate in predictable ways. Since God created us in His image, I have a rational reason to have confidence in my senses that I can observe and understand His creation.
The secular worldview really cannot make sense of the universe. The Christian worldview does. Indeed, it is the Christian God that even makes science possible. As I've said, though, secular scientists can do a decent job in describing the universe; if their worldview is so arbitrary, contradictory, and self defeating, how are they able to do that? It's only because my worldview is true!! Cool, huh!?
