[53] Stxian: The reason why Marx
say that use values are the “material carriers” of exchange
value is because that use values represented a paticular
commodity's usefulness, in another word, human's desire to
acquire such commodity and human's motive or objective
behind the desire and needs. In general, use values are
closely associated with a commodity's exchange value.
Because through people's need and want of that commodity and
some other commodity, people usually trade with each other
in ancient societies. Both sides wanted to trade something
that are usefulness, that is both sides wanted a commodity
with a use value and is exactly what he needs. This means
that people trade X good a to Y good b, so, X=Y, this
function is the exchange value of both good a and good b.
This is what Marx meant by use value as a material carrier
to exchange value. A commodity has to have a use value
first, then it can be traded or exchanged, and in terms, use
value itself serves as a material carrier. |
