This article examines the textual alteration strategy carried out by Dominicus Gundissalinus in his original works. One of the most striking examples of this approach can be detected in the large quotation of Ibn Sīnā's Metaphysica I, 6–7 in Gundissalinus’ cosmological treatise De processione mundi, in which the Spanish philosopher variously modifies the text he translated a few years before. After a short presentation of Gundissalinus’ double role as translator and philosopher, the study moves on to the analysis of Ibn Sīnā's doctrine of necessary and possible being, and the five demonstrations of the unrelated uniqueness of necessary being offered by Ibn Sīnā. These arguments are directly quoted by Gundissalinus: nevertheless, the author modifies the text in many passages, here examined through the analysis of some representative excerpts. The results of this enquiry suggest that Gundissalinus is following an effective alteration strategy, envisaging at least two main purposes: the clarification of Ibn Sīnā's line of reasoning, and the doctrinal assimilation of Metaphysica's theories in his original philosophical system. In appendix to this article the whole text of the two versions of Metaphysica I, 6–7 is presented.

冈迪萨利努斯论必要的存在：阿维森纳形而上学展览中的文本和教义改变

本文检视 Dominicus Gundissalinus 在其原作中执行的文本修改策略。这种方法最引人注目的例子之一可以在 Ibn Sīnā 的大量引文中发现形而上学I, 6–7 在 Gundissalinus 的宇宙学论文中世界游行，其中西班牙哲学家对他几年前翻译的文本进行了各种修改。在简要介绍了 Gundissalinus 作为翻译家和哲学家的双重角色之后，本研究继续分析伊本·西纳的必然存在和可能存在学说，以及伊本·西纳提出的关于必然存在的不相关唯一性的五个证明。Gundissalinus 直接引用了这些论点：尽管如此，作者在许多段落中修改了文本，这里通过对一些代表性摘录的分析来检验。这项调查的结果表明 Gundissalinus 正在遵循一种有效的改变策略，设想至少有两个主要目的：澄清 Ibn Sīnā 的推理路线，以及在教义上同化形而上学的理论在他原来的哲学体系中。本文附录两个版本的全文形而上学I, 6-7 呈现。
