As I put more of Marx’s value theory together, this is what I come up with — and this may require further discussion: I really like the idea from I.I. Rubin of thinking of value as having three (internally connected) dimensions of “substance”, “magnitude”, and “form”. As of today my interpretation is this:
1. Substance — the abstraction of concrete labor through commodity exchange.
2. Magnitude — quantitative equivalence made possible by exchange value; exchange value understood as the concrete manifestation of the form of value.
3. Value Form — universal exchangeability. The form of value in terms of the abstract form of labor.
Now, “internally connected” means that in terms of what is being analyzed — i.e. bourgeois capitalist social relations of commodity production and exchange — each dimension can only be properly understood in terms of the other two. So, the substance of value cannot be understood independently of the purpose of production — for exchange value. The magnitude of value (or the concrete “form” of value), which is exchange value, cannot be understood independently of “exchangeability” (the abstract value form) nor independently of abstract, generalized labor (the substance). Finally, the form of value, “exchangeability”, cannot be understood independently of substance and magnitude.
Right???
