This question must have its point for decision, and therefore the question and the point for decision are not different, but there are more
is not the question of fact ultimately referred to the question of quality ? For if Clodius lay in wait for Milo, it follows that he was justifiably killed. But when the case is shifted to some other point far removed from the original question, even in this case the question will be found to reside in the point for decision.
As regards these questions Cicero is slightly inconsistent with himself. For in the Rhetorica, as I have already mentioned, he followed Hermagoras, while in the Topicai [*](Top. xxv. 95. ) he holds that the κρινόμενον or disputed point is originated by the basis, and in addressing the lawyer Trebatius on this subject he calls it the point at issue, and describes the elements in which it resides as central arguments or foundations of the defence which hold it together and the removal of which causes the whole defence to fall to the ground.
