A sixteenth-century Neoplatonic synthesis: Francesco Piccolomini's theory of mathematics and imagination in the Academicae contemplationes

  • GUY CLAESSENS (a1)
Abstract
Abstract

The metamathematical framework of the early modern period is primarily determined by two presuppositions stemming from the Aristotelian tradition: (1) mathematical objects are abstracted from sensible matter; (2) imagination is a reproductive faculty exclusively connected with the sensible realm. The recovery of the works of the Greek commentators confronted the early modern readers with rivalling philosophical–mathematical views that explicitly called into question some of their previously undisputed assumptions. In this article I will argue that Francesco Piccolomini (1523–1607) in his Academicae contemplationes brings about an original fusion of these colliding horizons, by transposing the synthesis established by (?)Simplicius between Aristotelian abstractionism and Neoplatonic innatism into the sixteenth century.

2 The authorship of the De Anima commentary was already questioned by Francesco Piccolomini himself (In tres libros Aristotelis de anima lucidissima expositio, Venice, 1602, f. 216r), and is still disputed. Bossier Fernand and Steel Carlos, ‘Priscianus Lydus en de “In de anima” van Pseudo(?)-Simplicius’, Tijdschrift voor Filosofie (1972) 34(4), pp. 761822, French summary 821–822, attribute it to Priscian. For a different view see Hadot I., Le problème du néoplatonisme alexandrin: Hiéroclès et Simplicius, Paris: Etudes augustiniennes, 1978, pp. 193202. Since Steel's and Bossier's arguments contra Simplicius' authorship are convincing – while their pro-Priscian arguments are still much debated – I refer to the commentary's author as ‘(?)Simplicius'.

(6), pp. 100–101: ‘Ex adverso Proclus inter platonicos nemini secundus, in primum Euclidis manifeste asserit, rationibusque confirmat, rerum mathematicarum dari Ideas; & iure quidem: nisi enim daretur Idea recti, Idea circuli, Idea lineae; haec nullibi invenirentur, & evanescerent mathematicae scientiae; cum in materia nec rectum sine obliquitate, nec circulus exacte rotundus, nec linea sine latitudine inveniatur.’ See Proclus, in Eucl., 12, 19–26.

30 Piccolomini, op. cit. (6), p. 103. Piccolomini adds the sentence ‘and therefore the Ideas are able to display the images of mathematical objects in the imagination’ (& propterea valent Ideae imagines mathematicorum in phantasiam expromere). I cannot, however, explain in which way the Ideas themselves could display projections in the imagination, except indirectly.

35 Both Iamblichus' De secta pythagorica and Syrianus' commentary on Metaphysics M and N were known in the early modern period. Ficino, for example, translated Iamblichus' work (preserved in MS Vat. lat. 4530) probably before 1464; see Celenza Christopher, ‘Pythagoras in the Renaissance: the case of Marsilio Ficino’, Renaissance Quarterly (1999) 52, pp. 667711, 692–693. Syrianus' commentary was translated by Hieronymus Bagolinius: Syriani antiquissimi philosophi interpres in II, XIII et XIV libros Aristotelis Metaphysices commentaries, Venice, 1558. Piccolomini mentions Syrianus' work in his Naturae totius universi scientia perfecta atque philsophica, p. 399 – I follow the second edition, Frankfurt, 1628.

44 Piccolomini uses the uncommon adjective animarius as equivalent for the Greek ψυχικὸς, since, according to Syrianus, this number belongs to the soul.

52 Piccolomini, op. cit. (6), pp. 352–353: ‘Mathematica, quae certissima dicitur scientiarum, minime est scientia: tum quia non de intelligibilibus, sed de sensibilibus est: tum insuper, quoniam non traditur per principia scientiae … Promuntur quidem in facultatem imaginandi formae illae, quae a mathematico considerantur, ab anima per rationes; ut cum Proclo etiam Simplicius manifestavit; attamen Mathematicus rationes eas non cognoscit, nec ad eas, & longe minus ad ideas elevatur: aliud enim est cognoscere per rationes, & cognoscere rationes'.

53 Proclus, in Eucl., 55, 5 ff.

54 Proclus, in Eucl., 54, 27–55, 6: ‘For the understanding contains the ideas but, being unable to see them when they are wrapped up, unfolds and exposes them and presents them to the imagination sitting in the vestibule; and in imagination, or with its aid, it explicates its knowledge of them, happy in their separation from sensible things and finding in the matter of imagination a medium apt for receiving its forms’. Cf. Proclus, in Eucl., 141, 4–7: ‘Therefore just as nature stands creatively above the visible figures, so the soul, exercising her capacity to know, projects on the imagination, as on a mirror, the ideas of the figures; and the imagination, receiving in pictorial form these impressions of the ideas within the soul, by their means affords the soul an opportunity to turn inward from the pictures and attend to herself’. All translations from Proclus’ commentary on Euclid are from Morrow Glenn R. (tr.), Proclus: A Commentary on the First Book of Euclid's Elements, Princeton: Princeton University Press, 1992, with some modifications.

57 Motta oversimplifies matters when he states that Piccolomini simply copies Proclus’ system; see Motta, op. cit. (14), p. 30.

60 Piccolomini, op. cit.
