Histories of philosophy tend to portray philosophy as a solo enterprise: the achievement of exceptionally gifted philosophers, reached by means of their intellectual powers alone. However, for more than fifteen centuries in the West (c.50 BCE–c.1600 CE), a different ‘style’ of philosophy was widespread in the whole Mediterranean area, namely, philosophical commentaries. Commentaries are intrinsically collective enterprises in which many voices harmonise: the authoritative text, the pre-existing tradition of analysis, and the commentator’s own discussion.
PolyphonicPhilosophy aims to study Latin commentaries on logic from a special time in the history of education: the so-called Long Twelfth Century (1070–1220). In this period, extensive commentaries start to be written on works by Aristotle, Porphyry, and Boethius. Important preliminary research has enabled scholars to catalogue more than 200 logical commentaries of varying lengths. Many are still unpublished, but preliminary transcriptions show that they were very sophisticated, with many new ideas being tried out.
But not only are these texts remarkable – the manuscripts in which they are found also have some unique features. Twelfth-century logical commentaries were quickly surpassed and, consequently, circulated in very few manuscripts, all from the twelfth century itself. This seemingly unfortunate situation turns out to be an advantage for research. The few manuscripts encapsulating this whole production (c.40 overall) allow us to jump, so to speak, in the time and context in which the texts were written down. Through these tiny, unadorned books (probably belonging to the teacher himself, or to his students) one can have a direct glimpse into 12th-century school practices. The analysis of these manuscripts is, therefore, the basis for the development of this project, which follows a concrete-to-abstract integrated research design aiming at three objectives:
O1: a comprehensive study of all relevant manuscripts.
O2: editions and studies of mainly unpublished logical texts, comparing them and trying to capture their ‘polyphony’.
O3: meta-analysis of the concepts and methodology used, from an interdisciplinary and historiographical perspective.
The project will impact not only the history of philosophy and history of logic, but also the history of education and history of the book. It will allow a new approach to be tested, based on approaching the same material from a variety of perspectives and disciplines.
