The subject has also a topical interest in view of the forthcoming debate concerning the 'Proposal for a Directive of the European Parliament on Consumer Rights' (SEC/2008/2544) and its subsequent implementation in the near future.

That Justinian did not mean to establish a general doctrine of just pricing is argued, also with reference to the historical context, in R. Zimmermann, The law of obligations, Roman foundations of the civilian tradition, Cape Town 1990, p. 259-268.
See J.W. Baldwin, The Medieval theories of the just price: romanists, canonists and theologians in the twelfth and thirteenth centuries, Transactions of the American Philosophical Society, 49 (1959), p. 3-92;
and K.S. Kahn, Roman and Frankish origins of the just price of medieval Roman and Canon Law, New York 1973.
See the gloss Iudicis ad C. 4,44,2.
The just price should not be considered a static or objective standard, however, as Johann Gottlieb Heineccius (1681-1741) wrongly thought the scholastics held it to be. In the early modern scholastic conception, the just price is simply the market price under competitive circumstances, or the price set by the public authorities taking into account market factors like scarcity and abundance; cf. O. Langholm, The legacy of scholasticism in economic thought: antecedents of choice and power, Cambridge 1998, p. 77-99.
See D. 19,1,13pr. and D. 19,1,6,4. The early modern scholastics, however, pay more attention to the aedilitian remedies of Roman law, which could only be used during a limited time for rescission (actio redhibitoria) or price reduction (actio quanti minoris), not for all damages. This may be due to the fact that in his Quodl. II q. 5 art. 2, Thomas Aquinas speaks about the provisions of civil law in case of an animal morbosum. Cf. Quaestiones de quolibet, in: Opera omnia iussu Leonis XIII edita, cura et studio fratrum praedicatorum, tom. 25, vol.2, Parisiis- Romae 1996, p. 228-229. The word morbosus is reminiscent of the morbus of animals, literally mentioned in the texts of the aedilitian edicts. See D. 21,1,1,1 and D. 21,1,38.

Contrary to what the title of this contribution might suggest, it does not contain a single reference to the vast reception of the case in the late Medieval, Renaissance, or early modern period.

Sibi enim est reus priusquam ceteris nec tam pudenda apud eum publicatio fagitii quam conscientia est'.
In Ambrose, De offciis, 3, 6, 39, (ed. Testard, supra, n. 25), p. 99, we fnd the businessmen claiming the following against their detractors: 'Num industria in crimen vocatur? Num diligentia reprehenditur? Num providentia vituperatur?'. This is exactly the kind of argument put forward by the scholastics of the early modern period to defend the Merchant of Rhodes' right not to disclose information about future market conditions.

Venditor autem, qui rem vendendam proponit, ex hoc ipso dat emptori damni vel periculi occasionem quod rem vitiosam ei ofert, si ex eius vitio damnum vel periculum incurrere possit: damnum quidem, si propter huiusmodi vitium res quae vendenda proponitur minoris sit pretii, ipse vero propter huiusmodi vitium nihil de pretio subtrahat; periculum autem, puta si propter huiusmodi vitium usus rei reddatur impeditus vel noxius, puta si aliquis alicui vendat equum claudicantem pro veloci, vel ruinosam domum pro frma, vel cibum sive venenosum pro bono. Unde si huiusmodi vitia sint occulta et ipse non detegat, erit illicita et dolosa venditio, et tenetur venditor ad damni recompensationem. Si vero vitium sit manifestum, puta cum equus est monoculus; vel cum usus rei, etsi non competat venditori, potest tamen esse conveniens aliis; et si ipse propter huiusmodi vitium subtrahat quantum oportet de pretio: non tenetur ad manifestandum vitium rei. Quia forte propter huiusmodi vitium emptor vellet plus subtrahi de pretio quam esset substrahendum. Unde potest licite venditor indemnitati suae consulere, vitium rei reticendo'.

This article also contains a more detailed historical and philosophical contextualization of early modern scholastic legal thought.

Stone, Scrupulosity, probabilism, and conscience, The origins of the debate in early modern scholasticism, in: H. Braun / E. Vallance (eds.), Contexts of conscience in early modern Europe, 1500-1700, London 2004, p. 1-16 and p. 182-188.
These various types of literature stem from commentaries on diferent parts of Thomas Aquinas' Summa Teologiae, notably on IaIIae, q. 90-108 and IIaIIae, q. 57-80, respectively. Their autonomization is not only indicative of the growing importance of legal and moral afairs for the early modern scholastics, however, but also of the relative autonomy and independence of the latter authors with regard to Thomas's teachings.
See Augustine, Epistula 153, num. 20 [CSEL 44, III, 419]: 'Si enim res aliena, propter quam peccatum est, cum reddi possit, non redditur, non agitur poenitentia, sed fngitur: si autem veraciter agitur, non remittetur peccatum, nisi restituatur ablatum; sed, ut dixi, cum restitui potest'.

This and similar examples can be found in other writers. In Domingo de Báñez (1528-1604) the young nobleman is a soldier who wants to go to battle. See Dominicus Báñez, Decisiones de iure et iustitia, Venetiis 1595, ad IIamIIae, quaest. 77, art. 3, p. 358.

There possibly is a basis for the distinction between surmountable (non-excusable) and invincible (excusable) ignorance in Roman law, e.g. in D. 19,2,19,1, and the pair of ideas returns in 18th century authors like Augustin Leyser; see Zimmermann, The law of obligations (supra, n. 14), p. 367-368, and p. 869-870. It is arguable, however, that the first systematic and general application of the distinction between ignorantia invincibilis and ignorantia vincibilis stems from the scholastic tradition.

Aries Pinellus, De rescindenda venditione, cum annotationibus Emanuelis Soarez, Rinthelii 1667, part. 3, cap. 2, num. 22-24, p. 418-419. Pinellus mentions that Fulgosius disagreed with Bartolus's condemnation of a merchant making profts on the basis of insider information. Fulgosius argued, according to Pinellus, that a contracting party should be allowed to use his careful cleverness (astutia et diligentia) to his own advantage. Pinellus, however, thinks it is safer to follow the common opinion based on Bartolus. What is more, Pinellus thinks that in the court of conscience, as opposed to the forum externum, the 'Merchant of Rhodes' is never allowed to make profts on the basis of his dominant knowledge position, even if knowledge does not concern the enactment of a future decree. He expressly defends Cicero's view. Molina clearly has no legitimate claim to authoritative support from Pinellus, then.
