80 ON COMPARING COMMODITIES

would necessarily imply, that the two commo-
dities A and B might be equal in value,
although the value of the labour employed in
one was greater or less than the value of the
labour employed in the other; or that A and B
might be unequal in value, if the labour em-
ployed in each was equal in value. But this
difference in the value of two commodities,
which were produced by labour of equal value,
would be inconsistent with the acknowledged
equality of profits, which Mr. Ricardo main-
tains in common with other writers *.

It is probable, therefore, that this was not
Mr. Ricardo’s meaning, but that he uncon-
sciously confounded this proposition with an-

of A at two different periods, No. 1 and 2, was
