What do you mean by ‘action axiom’?
http://mises.org/daily/5014 (Read the section where it describes it)
As to your friend, I suggest you back away slowly and then run.
"The starting point of all praxeological thinking is not arbitrarily chosen axioms, but a self-evident proposition, fully, clearly and necessarily present in every human mind. An unbridgeable gulf separates those animals in whose minds this cognition is present from those in whose minds it is not fully and clearly present. Only to the former is the appellation man accorded. The characteristic feature of man is precisely that he consciously acts. Man is Homo agens, the acting animal. All—apart from zoology—that has ever been scientifically stated to distinguish man from nonhuman mammals is implied in the proposition: man acts. To act means: to strive after ends, that is, to choose a goal and to resort to means in order to attain the goal sought.

The starting point of praxeology is a self-evident truth, the cognition of action, that is, the cognition of the fact that there is such a thing as consciously aiming at ends."
Ludwig Von Mises - The Ultimate Foundation of Economic Science
I’ve seen dogs acting, and it;s not just instinct. They figured ou on their own how to open door knobs and quickly butt their heads on the door to get in before it twists back. they have a clear goal in mind, getting into the room, and have reasoned out how to do it.
I understand monkeys are even smarter. Not to mention all the experiments with mice.
So it seems to me all those animals act, too. Why does Mises say it’s onl humans?
