There are also three aims which the orator must always have in view; he must instruct, move and charm his hearers. This is a clearer division than that made by those who divide the task of oratory into that which relates to things and that which concerns the emotions,

since both of these will not always be present in the subjects which we shall have to treat. For some themes are far from calling for any appeal to the emotions, which, although room cannot always be found for them, produce a most powerful effect wherever they do succeed in forcing their way.

The best authorities hold that there are some things in oratory which require proof and others which do not, a view with which I agree. Some on the other hand, as for instance Celsus, think that the orator will not speak on any subject unless there is some question involved in it; but the majority of writers on rhetoric are against him, as is also the threefold division of oratory, unless indeed to praise what is allowed to be honourable and to denounce what is admittedly disgraceful are no part of an orator's duty.

It is, however, universally agreed that all questions must be concerned either with something that is written or something that is not. Those concerned with what is written are questions of law, those which concern what is not written are questions of fact. Hermagoras calls the latter rational questions, the former legal questions, for so we may translate λογικόν and νομικόν.
