 Arguments aim to bring about assent; more precisely  (see Text 8 above), when conceptions have been gained that produce in the mind both the meaning of the terms in a given proposition, and the form of composition of these terms, assent “occurs when there takes place in the mind a relating of this form to the things themselves as being in accordance with them…” In fact, different kinds of discourse can bring about one or other kind of assent, or something enough like assent to be included in a general theory of discourse. I give Tûsî's statement of the Avicennan version of the context theory; it is the neatest statement I know of the criteria that divide kinds of discourse and the assents for which each aims.
