As I argue in my book, “I do not know that laws of nature do not change, and that in natural sciences the past can be a guide to the future. But I can have reasons for believing these things, and understand why I believe. Causality is a praxeological a priori category. … for the sake of (a) optimal psychological balance, (b) success and happiness, and (c) outright continuation of life, it is best to hold that natural laws are immutable.” (SAtK, I, 26)
However, for these (a)-(c) it is sufficient to lack the false idea that causality does not exist, and that the world is or might become chaotic. Not only adult humans but babies and cats all are sensible in this regard. I would even say, imitating Descartes, that the easy confidence that causality is a feature of the world is a mark of the Creator upon our minds. To obtain the true idea that the world is lawful requires philosophizing.
