“Like classical economists, Marx, too, claimed that commodity was use-value and value at the same time; the difference was that he grasped it as a synthesis that might happen in the future. He saw it ex ante facto. Seen in this way, there is no guarantee as to whether the synthesis is realized. What does this difference—ex post facto and ex ante facto—really mean? We should scrutinize this by returning to Kant.”
