[11] Deni: Valid exchange values vs. exchange values. Marx is pointing out that every exchange of values needs to be valid. In an
example that he is giving in 127:2, “a given quantity of wheat is equated
to some quantity of iron,” he is saying that a quality is involved as well.
We can not exchange one substance to another if the values are not equal;
otherwise that transaction would fail and would have impact on productivity
and revenue of a producer. “Valid” simply means (and especially back in 17th
century) eye for an eye, or one pound of wheat for 2 pounds of iron, just
because the validity of the iron was measured this way back then or vice
versa. |
