Book 3
5.9
As for the σύνεχον the central argument, as I have mentioned it is called by some, or the foundation as it is called by others, or as Cicero De Inv. I. xiv. 19. styles it the strongest argument of the defender and the most relevant to the decision of the judge, some regard it as being the point after which all enquiry ceases, others as the main point for adjudication.
5.10
The motive of the deed does not arise in all controversial cases. For how can there be a motive for the deed, when the deed is denied? But when the motive for the deed does come up for discussion, they deny that the point for the decision of the judge rests on the same ground as the main question at issue, and this view is maintained by Cicero De Inv. I. c.: Part. Or. xxx. 104. in his Rhetorica and Partitiones.
