Cicero's Tusculanae disputationes and his project of a Roman philosophy. A cooperative commentary on its fifth book in philosophical, literary and cultural-historical perspective

根据西塞罗（公元前106-43年）在《论占卜》（De divatione） 2,1 -4中提供的作品概观，他的《图斯库兰论辩》的第五卷具有特殊的意义：它不仅标志着这篇文章的高潮，而且在他的真正罗马哲学计划中占据了中心位置。然而，它在现代学术中大多被忽视了。该项目旨在重新发现和深入分析这本书，基于对现有学术文献的批判性评估和对文本的跨学科方法（包括德语翻译，详细评论，特别是六篇全面的解释性文章）。我们的目标是对这篇文章建立一个连贯的整体解读这篇文章也将在图斯库伦人的其他四本书中被语境化并将与西塞罗的《上帝与邪恶》联系起来，这是另一篇伦理学著作，写于图斯库伦之前不久。并在很多层面上与之相连。通过这种方式，我们将获得关于图斯库兰之争的总体目的的新颖见解，以及关于西塞罗哲学计划的整体结构和意图的新颖见解。因此，对于真正的罗马哲学，西塞罗将自己塑造为奠基人的形象，将比最近致力于这一主题的文献更加引人注目。

According to the conspectus of his works, which Cicero (106-43 BCE) offers in "De divinatione" 2,1–4, the fifth book of his Tusculan Disputations has a special significance: it does not only mark the climax of this writing but it occupies a central place in his project of a genuine Roman philosophy. Nevertheless, it has mostly been neglected in modern scholarship. This project aims at a rediscovery and in-depth analysis of this book, based on the critical evaluation of the existing scholarly literature and on an interdisciplinary approach towards the text (including a German translation, a detailed commentary and especially six comprehensive interpretive essays). The goal is to establish a coherent overall reading of this text which will also be contextualized within the other four books of the Tusculans and will be related with Cicero’s De finibus bonorum et malorum, another ethical writing which was composed shortly before Tusc. and is connected with it on many levels. In this way, we will gain novel insights with regard to the overall purpose of the Tusculan Disputations as well as concerning the structure and intention of Cicero’s philosophical project as a whole. Thus the profile of a genuine Roman philosophy for which Cicero fashions himself as a founding figure will be brought into a much sharper focus than it has been done in recent literature devoted to this topic.
