Thorough Preparation Essential
As every orator is remarkable for his manner, the care of one having been imputed to slowness, and the facility of another to rashness, it may not be amiss to point out here a medium. Let him come for pleading prepared with all possible care, as it must argue not only neglect, but also a wicked and treacherous disposition in him, to plead worse than he can in the cause he undertakes, therefore he should not undertake more causes than he is well able to handle.
He should say things, studied and written, in as great a degree as the subject can bear, and, as Demosthenes says, deeply engraven, if it were possible, on his memory, and as perfect as may be. This may be done at the first pleading of a cause, and when in public judgments a cause is adjourned for some time before it comes to a rehearsing. But when a direct reply is to be made, due preparations are impracticable; and even they who are not so ready find what they have written to be rather a prejudice to them if anything unexpectedly is brought forward; for it is with reluctance that they part with what they have prepared, and keeping it in mind during the whole pleading, they are forced to continually wonder if anything can be taken from it to be included in what they are obliged to speak extempore. And tho this may be done, there will still be a lack of connection, and the incoherence will be discoverable from the different coloring and inequality of style. Thus there is neither an uninterrupted fluency in what they say extempore, nor a connection between it and what they recite from memory, for which reason one must be a hindrance to the other, for the written matter will always bring to it the attention of the mind, and scarcely ever follow it. Therefore in these actions, as country-laboring men say, we must stand firmly on our legs. For, as every cause consists of proving and refuting, whatever regards the first may be written, and whatever it is certain the opponent will answer, as sometimes it is certain what he will, may be refuted with equal care and study.
Knowing the cause well is one essential point for being prepared in other respects, and listening attentively to all the opponent states, is another. Still we may previously think of many particular incidents and prepare the mind for all emergencies, this being of special advantage in speaking, the thought being thereby the more easily transmitted and transferred.
But when in answering or otherwise there may be necessity for extempore speaking, the orator will never find himself at a loss and disconcerted, who has been prepared by discipline, and study, and exercise, with the powers of facility, and who, as always under arms and ready for engaging, will no more lack a sufficient flow of speech in the pleading of causes than he does in conversation on daily and domestic occurrences; neither will he ever, for lack of coming duly prepared, decline burdening himself with a cause, if he has time to learn the state of it, for with anything else he always will be well acquainted.
