at the construction of a tragedy in two quite different ways, and that
it is material to find the best of the two; and that thus, in any given
instance, it is necessary first to define the opposing sides in the
conflict. I will give one or two examples. In some tragedies, as we saw
in our first lecture, the opposing forces can, for practical purposes,
be identified with opposing persons or groups. So it is in _Romeo and
Juliet_ and _Macbeth_. But it is not always so. The love of Othello may
be said to contend with another force, as the love of Romeo does; but
Othello cannot be said to contend with Iago as Romeo contends with the
representatives of the hatred of the houses, or as Macbeth contends with
Malcolm and Macduff. Again, in _Macbeth_ the hero, however much
influenced by others, supplies the main driving power of the action; but
in _King Lear_ he does not. Possibly, therefore, the conflict, and with
it the construction, may best be regarded from different points of view
in these two plays, in spite of the fact that the hero is the central
figure in each. But if we do not observe this we shall attempt to find
the same scheme in both, and shall either be driven to some unnatural
view or to a sceptical despair of perceiving any principle of
construction at all.

With these warnings, I turn to the question whether we can trace any
distinct method or methods by which Shakespeare represents the rise and
development of the conflict.

(1) One at least is obvious, and indeed it is followed not merely during
the conflict but from beginning to end of the play. There are, of
course, in the action certain places where the tension in the minds of
the audience becomes extreme. We shall consider these presently. But, in
addition, there is, all through the tragedy, a constant alternation of
rises and falls in this tension or in the emotional pitch of the work, a
