[OPE-L:4116] Re: use value and value

Hi Paul,

This is a sensible supposition--"that the use value(s) yielded by a
commodity are usually inseparable from the material shape of the commodity
itself, so that changes in value and use value normally occur
together"--which helps explain why the analysis of machinery in production
has been so confusing. Returning to Andrew's observation which began this
discussion, the depreciation of the machine and its contribution to
production are two different things--the former being its exchange-value
(on which depreciation is calculated, as Marx noted), the latter being its
use-value. But both expire at the same time, and it's practically
impossible to affect one without affecting the other, so it's been very
easy for analysts of all persuasions to regard the two aspects as simply one.
