I would say that natural laws are the reflection of natural order. The question is, Is order physical or rational? and I would say that it is clearly rational.
Certainly math real and is an important aspect of science, but math is not physical, not matter/energy, but rational. Math is a way we understand the order of nature, but it is not physical.
Measurements are rational, not physical.
Brains can be considered physical, but minds are not. Minds think which is not a physical activity, but a rational activity. The relationship of the brain to the mind is the relationship between computer hardware (brain) and computer software (mind)
To say that the good and beautiful are products of our minds indicates that there is nothing objective about these concepts, which is not true. Love is good. Flowers are beautiful.
Yes, it is the mind that makes that decision as to these values, but it makes them rationally and based on objective values.
The question I usually raise is, Is life good? If life is not rational and inherently good, then there is no reason for living. Survival is not a rational goal in life if life has no meaning and purpose.
I would not separate truth from survival. Truth makes survival possible and meaningful. I wonder if we could show that belief in God makes life longer and more enjoyable (on average) this would convince non-believers that God is Real. I don’t think so.
Even so I do think that God created humans i9n God’s Image which does act to insure their survival and to seek God’s Truth and Presence in their lives. Now it appears that too many of us are content with the scientific world that we have created using that Image and not the Kingdom of God promised by Jesus through the Spirit.
