Classic Edition For 25 years the Institute for Theology and Peace has been exploring the peace ethics “classical” academics from Augustine to Thomas Aquinas, from the early modern Dominican theologian, Francisco de Vitoria, to the Jesuit Francisco Suarez up until the Popes of the 20th century, like John Paul II. The renowned library of the peace ethics tradition has grown to include over 20 volumes of this classical teaching. In cooperation with, among others, Prof. Matthias Lutz-Bachmann, University of Frankfurt, the relevant tractates De lege and De iustitia of the summa commentary by Francisco de Vitoria and relevant peace ethics texts by Francisco Suarez have been worked on and published by frommann-holzboog. Currently, in this area of study, the following writings are researched: Luigi Taparelli d’Azeglio, Saggio teoretico di diritto naturale appoggiato sul fatto The major work of Luigi Taparelli d’Azeglio SJ (1793 – 1862) is as fundamental to modern catholic social teaching as he himself is unknown in modern times. It is no coincidence that this is so. Taparelli had influenced the young Gioacchino Pecci, the later Pope Leo XIII, as a teacher in the late 1820s and entrusted him with support tasks. Half a century later, when Leo XIII, supported by other students of Taparelli, promoted his ideas in catholic doctrine, the ‘father’ of these ideas and concepts was mentioned as little as possible for reasons of acceptance. Taparelli’s work Saggio teoretico di diritto naturale appoggiato sul fatto, published in 1855 in its fourth edition – the last to be completed and revised by him – is the blueprint for the modern catholic social doctrine launched by Pope Leo XIII: the fundamental considerations and outlines set out in it are – for example in the ethics of peace and conflict – relevant also for current theological-ethical positioning in the Catholic Church. In the German-speaking world, however, there is only a translation of the first edition, published successively in the years 1840-43; it dates back to 1845. Against this background, the Institute for Theology and Peace wants to meet the desideratum of a modern translation of the fourth edition of the Saggio teoretico di diritto naturale appoggiato sul fatto. The project, which began in November 2021, is scheduled to take 30 months to complete, so that publication as a bilingual edition within the established framework of the already published editions of the classics is aimed for 2024/25.
