Gil, if they had nothing in common, then chance would determine their
exchange ratios, correct? But over time exchange ratios become stable. As
Carchedi points out: "It is this relative stability wich compels us to
presuppose a common thing (abstract labor) whose relative stability (labour
socially necessary) explains the relative stability of the exchange ratios,
of the proportions in which products are exchanged." I find myself unable
to devote real attention to these threads because of how much difficulty I
am having with other things I must finish. So just a quick challenge so I
can stay in the game.
