 As for (i), Aristotle points out in Rhet. I.2 that some things are specific to physics, others to ethics, etc. This seems to suggest a distinction between topoi (or other building blocks of arguments) that are peculiar to the different sciences on the one hand and other topoi that are not, but are instead applicable to all sciences and fields of knowledge alike—just as (most of) the dialectical topoi of the Topics are. However, from Rhet. I.3 on, Aristotle makes the readers think, by contrast, that ‘specific’ refers to the different genres of rhetoric, so that some topoi are specific to deliberative, others to epideictic, and still others to juridical speech. Correspondingly, this would require a sense of being‘common’ that boils down to saying that they are not specific to one single species of speech, but that does not amount to the topic-neutrality of the dialectical topoi.
