In the first place, we must note the direction which
the argument is likely to take, since we cannot run
our race unless we know the goal and the course.
It is not enough to know what are the parts1
which forensic pleadings are divided or the principles determining the order of the various questions,
important though these points are. We must realise
what should come first, second, and so on, in the
several parts; for these points are so closely linked
together by the very nature of things that they
cannot be separated, nor their order changed, without giving rise to confusion.
