[Footnote 1: Even Ashley states that 'the doctrine had thus a close resemblance to that of modern Socialists; labour it regarded both as the sole (human) cause of wealth, and also as the only just claim to the possession of wealth' (_Op. cit._, vol. i. part ii. p. 393).] [Footnote 2: _Op. cit._, p. 50.] The idea that the scholastics traced all value to the labour expended on production is rejected by many of the most prominent writers on mediæval economic theory. Roscher draws particular attention to the fact that the canonist teaching assigned the correct proportions in production to land, capital, and labour, in contrast to all the later schools of economists, who have exaggerated the importance of one or the other of these factors.[1] Even Knies, who was the first modern writer to insist on the importance of the cost of production as an element of value, states that the Church sought to fix the price of goods in accordance with the cost of production (_Herstellungskosten_) _and_ the consumption value (_Gebrauchswerte_).[2] Brants takes the same view. 'The expenses of production are in practice the norm of the fixing of the sale price in the great majority of cases, above all in a very narrow market, where competition is limited; moreover, they can, for reasons of public order, form the basis of a fixing that will protect the producer and the consumer against the disastrous consequences of constant oscillations. The vendor can in principle be remunerated for his trouble. It is well that he should be so remunerated; it is socially useful, and is used as a basis for fixing price; but it cannot in any way be said that this forms the _objective measure of value_, but that the work and expense are a sufficient title of remuneration for the fixing of the just price of the sale of a thing. Some writers have tried to conclude from this that the authors of the Middle Ages saw in labour the measure of value. This conclusion is exaggerated. We may fully admit that this element enters into the sale price; but it is in no way the general measure of value.... The expenses of production constitute, then, _one_ of the legitimate elements of just price; they are not the _measure_ of value, but a factor often influencing its determination.'[3] 'Labour,' according to Dr. Cronin, 'is one of the most important of all the determinants of value, for labour is the chief element in cost of production, and cost of production is one of the chief elements in determining the level at which it is useful to buy or sell. But labour is not the only determinant of value; there is, _e.g._, the price of the raw materials, a price that is not wholly determined by the labour of producing those materials.'[4] [Footnote 1: _Political Economy_, s. 48.] [Footnote 2: _Politische Oekonomie vom Standpuncte der geschichtlichen Methode_, p. 116.] [Footnote 3: _Op. cit._, p. 112.] [Footnote 4: _Ethics_, vol. ii. p. 181.]
