[Footnote 2: _De Cont._, quoted by Roscher, _Geschichte_, p. 20.] [Footnote 3: Tit. 'Political Economy.'] [Footnote 4: Palgrave, _Dictionary_, tit. 'Justum Pretium.'] [Footnote 5: Brants, _op. cit._, p. 202.] The cost of the labour of production was, however, by no means the only factor which was admitted to enter into the determination of value. The passage from Gerson dealing with the circumstances to which the prince must have regard in fixing a price, which we quoted above, shows quite clearly that many other factors were recognised as no less important. This appears with special clearness in the treatise of Langenstein, whose authority on this subject was always ranked very high. Bernardine of Siena is careful to point out that the expense of production is only one of the factors which influence the value of an object.[1] Biel explains that, when no price has been fixed by law, the just price may be arrived at by a reference to the cost of the labour of production, and to the state of the market, and the other circumstances which we have seen above the prince was bound to have regard to in fixing a price. He also allows the price to be raised on account of any anxiety which the production of the goods occasioned him, or any danger he incurred.[2] [Footnote 1: 'Res potest plus vel minus valere tribus modis; primo secundum suam virtutem; secondo modo secundum suam caritatem; tertio modo secundum suam placibilitatem et affectionem.... Primo observat quemdam naturalem ordinem utilium rerum, secundo observat quemdam communem cursum copiae et inopiae, tertio observat periculum et industriam rerum seu obsequiorum' (Funk, _Zins und Wucher_, p. 153).] [Footnote 1: 'Sollicitudo et periculum,' _Op. cit._, IV. xv. 10.] It will be apparent from the whole trend of the above that, whereas the remuneration of the labour of all those who were engaged in the production of an article, was one of the elements to be taken into account in reckoning its value, and consequently its just price, it was by no means the only element. Certain so-called Christian socialists have endeavoured to find in the writings of the scholastics support for the Marxian position that all value arises from labour.[1] This endeavour is, however, destined to failure; we shall see in a later chapter that many forms of unearned income were tolerated and approved by the scholastics; but all that is necessary here is to draw the attention of the reader to the passages on value to which we have referred. One of the most prominent exponents of the untenable view that the mediævals traced all value to labour is the Abbé Hohoff, whose argument that there was a divorce between value and just price in the scholastic writings, is ably controverted by Rambaud, who remarks that nobody would have been more surprised than Aquinas himself at the suggestion that he was the forerunner of Karl Marx.[2]
