Institutio Oratoria

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.
