ABSTRACT
The proof that indirect exchange/barter is something necessary, leads to the fact that there must be goods that one does not exchange for their own sake, but rather only to use them for further exchanging, consequently to the phenomenon of money. Above all, the monetary theory, as it is stated, forms nothing less than an integral component of the price theory. In fact, it has become typical to approach it entirely by itself, and to remove the "monetary veil" that encases the economical processes in pure-theoretical discussions. So then the monetary theory only emerges as an annex of the remaining structure of science because it is also an economical one, but needs special aides in order to do this. As soon as more than two goods are supposed to be exchanged between more than two individuals, acts of exchange will take place whose purpose is the acquisition of goods for further complete or partial exchange.
