"We return to the problem of the mediation between thought and reality. The truth of money is that which is the same in thought and in reality. If we locate this truth on the side of reality, then the truth of this truth can never be given within thought. If we locate this truth on the side of thought, then the truth of this truth can never be given within reality. In the case of money, if we understand it essentially as a commodity, then we cannot explain its appearance within thought, both as a measure of value and as an object of creation. If, by contrast, we take money to be essentially a standard of measure or comparison, then we cannot explain its real force and value. Money is a promise or sign of value, and as such the truth of money is not self-identically true. The value of a promise is not the same as the promised value."
Philip Goodchild Theology of Money (2009) p.17
