There are further reasons why we should sometimes dispense with partition. In the first place there are many points which can be produced in a more attractive manner, if they appear to be discovered on the spot and not to have been brought ready made from our study, but rather to have sprung from the requirements of the case itself while we were speaking. Thus we get those not unpleasing figures such as
It has almost escaped me,
I had forgotten,or
You do well to remind me.For if we set forth all that we propose to prove in advance, we shall deprive ourselves of the advantage springing from tile charm of novelty.
Sometimes we shall even have to hoodwink the judge and work upon him by various artifices so that he may think that our aim is other than what it really is. For there are cases when a proposition may be somewhat startling: if the judge foresees this, he will shrink from it in advance, like a patient who catches sight of the surgeon's knife before the operation. On the other hand, if we have given him no preliminary notice and our words take him unawares, without his interest in them having been previously roused by any warning, we shall gain a credence which we should not have secured had we stated that we were going to raise the point.
At times we must not merely avoid distinguishing between the various questions, but must omit them altogether, while our audience must be distracted by appeals to the emotion and their attention diverted. For the duty of the orator is not
Again, there are certain arguments which are weak and trivial when they stand alone, but which have great force when produced in a body. We must, therefore, concentrate such arguments, and our tactics should be those of a sudden charge in mass. This, however, is a practice which should be resorted to but rarely and only under extreme necessity when reason compels us to take a course which is apparently irrational.
In addition it must be pointed out that in any partition there is always some one point of such special importance, that when the judge has heard it he is impatient with the remainder, which he regards as superfluous. Consequently if we have to prove or refute a number of points partition will be both useful and attractive, since it will indicate in order what we propose to say on each subject. On the other hand, if we are defending one point on various grounds partition will be unnecessary.
