Book 10
7.29
Indeed I am not sure that, if we practise both with care and assiduity, mutual profit will not result, and writing will give us greater precision of speech, while speaking will make us write with greater facility. We must write, therefore, whenever possible; if we cannot write, we must meditate: if both are out of the question, we must still speak in such a manner that we shall not seem to be taken unawares nor our client to be left in the lurch.

It is, however, a common practice with those who have many cases to plead to write out the most necessary portions, more especially the beginnings of their speeches, to cover the remainder of that which they are able to prepare by careful premeditation and to trust to improvisation in emergency, a practice regularly adopted by Cicero, as is clear from his note-books. But the notes of other orators are also in circulation; some have been discovered by chance, just as they were jotted down previous to a speech, while others have been edited in book form, as in the case of the speeches delivered in the courts by Servius Sulpicius, of whose works only three speeches survive. These memoranda, however, of which I am speaking are so carefully drawn up that they seem to me to have been composed by himself for the benefit of posterity.
