OF VALUE.

the resemblance between two objects, depends
apon both, and changes with a change in either
of them.
Mr. Ricardo’s modifications of his doctrine
of the invariable value of a commodity produced
 by the same quantity of labour, make no
difference in the force and applicability of the
preceding remarks. For he still asserts, that a
commodity produced by a uniform quantity of
labour, would be of invariable value in relation
to commodities produced under the same circumstances
 ‘as itself¥, as to the proportions of
fixed and circulating capital, the durability of
the fixed capital, and the time required to bring
the commodity to market. If a commodity,
for instance, were produced solely by labour, and
always required the same quantity to produce it,
it would be of invariable value in regard to such
commodities as were produced by labour alone.
Mr. Ricardo, indeed, so far agrees with the view
here taken, as to maintain the impossibility
of finding any commodity of invariable value.
