Multae quippe orationes verae quidem sed obscurae Calcidius’ taxonomy of textual obscuritas

Resumen

At a certain point of his commentary on Plato’s Timaeus (317.15 ff. Wazink), Calcidius sets out to distinguish different kinds of obscurity that can affect a text. The first to be analysed is the obscuritas iuxta dicentem: in this case, obscuritas is said to depend on either a decision (studio) made by the author (this was the case of both Aristotle and Heraclitus), or the inefficacy of language (imbecillitas sermonis). Secondly, Calcidius takes into account the obscuritas iuxta audientem, i.e. that particular kind of obscurity which is due to both the novelty and even the oddity of the discourse (cum inaudita et insolita dicuntur), and the intellectual inadequacy of the listener (cum is qui audit pigriore ingenio est ad intellegendum). Thirdly, Calcidius mentions a kind of obscurity which is said to be iuxta rem. In other words, this obscurity is relative to any res (i.e. any object of analysis) which is such that it cannot be precisely and immediately understood. Note that Calcidius takes this to be the case of Plato’s chora: for, neither it can be perceived through the means of sense perception, nor it can be intellectually grasped. But, as Calcidius clarifies, the presence of a certain degree of obscurity in a text does not necessarily put its veritative value at risk, just as the being true of a text does not automatically entail its being clearly expressed (non statim quae vere dicuntur aperte etiam manifesteque dicuntur). Unfortunately, to this ancient example of hermeneutics no extensive study has ever been devoted, as Professor Franco Ferrari has often pointed out. So, my objective is to extensively scrutinise the general classification of obscuritates provided by Calcidius and then to relate it to the Middle Platonic strategies aimed at neutralising Plato’s obscuritas.
