Spectrology comes out of social conditions, not ambiguities in old books. But I wonder if this passage in Ricardo inspired some of the gothic mise-en-scène in the first part of Capital:
“The real price of every thing,” says Adam Smith, “what every thing really costs to the man who wants to acquire it, is the toil and trouble of acquiring it. What every thing is really worth to the man who has acquired it, and who wants to dispose of it, or exchange it for something else, is the toil and trouble which it can save to himself, and which it can impose upon other people.”
...what Smith and Ricardo mean is that transacting commodity for commodity, or labour for commodity is effectively reducible to a transaction of labour for labour, where commodities are valued according to the labour that goes into their production...
... on the other hand Ricardo's cut and paste can't help but suggest, though accidentally, that the commodity itself somehow attains hex properties, mysteriously "imposing toil on other people".
