[543] Leftyjace: Aristotle means that individuals will not exchange commodities unless they
are considered equal. If they somehow were not considered equal before, the
very fact that they were exchanged for each other indicates that in the eyes
of the agents they are now considered to be equal. Therefore, there cannot
be an exchange without equality. Further, two separate commodities can only
be considered to be equal if there is something in them - some facet, or
some substance inherent in them - that is common to the two commodities.
Therefore, there cannot be equality without commensurability. As far as the
difference between equality and commensurability: equality concerns itself
with equality between two things; commensurability can be present without
equality, as the two things may have something in common, but may not
necessarily be equal. |
