From a philosophical point of view, #money is a so called #subjectobject. It receives its objective meaning exclusively from the subjective appreciation of those who use it.
From the perspective of the radical #valuecritique, the #SubjectObjectGap is established by the introduction of the #Private ownership of #PrivateEconomy.
Subjectobjects can only be understood by their dialectical genesis.
The positivistic liberal #science have so far failed due to the explanation of money. Even famous classic economists admit this.
