For this blog, I will write about topics for 20 minutes and that is all.
Many people think about the law of marginal of utility and think about value scales. Well, value scales don’t exist, unless you are talking about a value scale in a very abstract sense.
I believe Rothbard, among many other Austrians, are very confused about this. If you are going to read this blog, you will get used to the fact that I probably not going to look up many of the things that I make reference to. Maybe I will later if people want, but many people may not read this blog.
Back to marginal utility. Whenever Mises talks about any economic laws, they are only in reference to actual actions that take place. So, when a person is thinking of a value scale, this is an action IN ITSELF. Therefore, value scales can’t be inherent in making actions. When I perform any action, I don’t choose this action among a list of actions that I may have partaken in. Instead, the law of marginal utility is a proposition (analytic a priori) that is inherent in actions themselves. Performing an action is tautologous to valuing something. I would like to give credit to Adam Knott (praxeology.org) on this, but I still think his formulation is in error, which I must reserve for another post.
For those who may be confused, praxeology makes no synthetic propositions. Praxeology takes action as given. It does not analyze the metaphysical grounds for accepting the action axiom. It merely analyzes the axiom and accepts its truth.
So, we now have the proposition: Performing an action is valuing something. Surely, I can right now perform an action that I don’t value, thereby disproving your proposition. Well my 20 minutes is up, so I should answer this objection in my next post.
