Dean Kenning << >> Chapter 4: The General Formula for Capital Page 251 One sum of money is distinguishable from another only by its amount. The process M – C – M [Money – Commodity – Money] does not therefore owe its content to any qualitative difference between its extremes, for they are both money, but solely to quantitative changes. More money is finally withdrawn from circulation than was thrown in at the beginning ... The value originally advanced, therefore, not only remains intact while in circulation, but increases its magnitude, adds to itself a surplus-value, or is valorized. And this movement converts it into capital. ... The simple circulation of commodities – selling in order to buy – is a means to a final goal which lies outside circulation, namely the appropriation of use values, the satisfaction of needs. As against this, the circulation of money as capital is an end in itself, for the valorization of value takes place only within this constantly renewed movement. The movement of capital is therefore limitless.
