ABSTRACT
The purpose of the dialogue1 is to discuss and closely examine the procession of the Holy Spirit, and to resolve the quarrel on such a controversial issue that exists between us and the Latins, aiming to eradicate the separation between the two originating from this [disagreement]. The dialogical form, because it suits the subtle argument of enquiries that require a particularly accurate examination, is above all fitting for the close scrutiny of ecclesiastical dogmas, and is useful and necessary for the discovery of the truth for those who do not want to quarrel; wherefore also some of the greatest teachers used this form of discourse.2
