Praxeology: Economics and Evolution

Before I respond more fully, I want to try to clear up a few things.

We are not talking only about “pure praxeology”, yes; we are talking about “applied praxeology”. My contention, albeit, to an extent, tentative, is that “pure praxeology”, the origin and method of which I explain here, especially between my first and second post, is the foundation of many fields that I call “applied praxeology”, including evolutionary biology, economics, and other things.

Also, you responded only to my stronger claim, that it is a model that helps us predict things. What about my weaker claim, that “if we find that certain things, like taking control of the provision of education, help that cause, that is, to survive, we are able to understand why so many states have done that”? I might be wrong that my approach allows us to predict things. But what about whether it simply allows us to understand things; in that example, what if it just allows us to understand why states take control of the provision of education but does not allow us to predict anything?

Do you have any idea what that would entail? An example of it would help.

You have just stated that it might be possible and gave an analogy, the one concerning marginal utility. But you have not shown me why it might be possible.
