The old conception of cost and value was designed to solve this fundamental problem: what is the relation, if any, between the importance to the community (R’s absolute value) not value in use of a commodity and its price (exchange value). They assumed that there was a relation of some sort between the two, and they expressed this misterious {sic} relation by such words as "cause" or “measure” - but obviously they did not mean what is their appropriate sense (analyse) (De Quincey, traditional confusion perpetuated by Bohm-B., Edg., Clark).
The modern conception is derived from the erroneous belief that the classics were literally looking for the “causes” of value, and not in its relation with importance, i.e. its “meaning”. It may be useful to find how the actual adjustments of prices come about in detail, to analys {sic} the interplay of the forces determining the refinements of equilibrium (though also in these we can pass ourselves of utility + disutility and operate with demand price + expenses of production). But it cannot give us an explanation of the social meaning of value, not even of its "ultimate” causes. Because, being psychological, sacrifice is measured by incentives: incentive implies free choice, voluntary acceptance or refusal: and this implies in the factor of production
