As a Shakespearean tragedy represents a conflict which terminates in a catastrophe, any such tragedy may roughly be divided into three parts. The first of these sets forth or expounds the situation,[17] or state of affairs, out of which the conflict arises; and it may, therefore, be called the Exposition. The second deals with the definite beginning, the growth and the vicissitudes of the conflict. It forms accordingly the bulk of the play, comprising the Second, Third and Fourth Acts, and usually a part of the First and a part of the Fifth. The final section of the tragedy shows the issue of the conflict in a catastrophe.[18] The application of this scheme of division is naturally more or less arbitrary. The first part glides into the second, and the second into the third, and there may often be difficulty in drawing the lines between them. But it is still harder to divide spring from summer, and summer from autumn; and yet spring is spring, and summer summer. The main business of the Exposition, which we will consider first, is to introduce us into a little world of persons; to show us their positions in life, their circumstances, their relations to one another, and perhaps something of their characters; and to leave us keenly interested in the question what will come out of this condition of things. We are left thus expectant, not merely because some of the persons interest us at once, but also because their situation in regard to one another points to difficulties in the future. This situation is not one of conflict,[19] but it threatens conflict. For example, we see first the hatred of the Montagues and Capulets; and then we see Romeo ready to fall violently in love; and then we hear talk of a marriage between Juliet and Paris; but the exposition is not complete, and the conflict has not definitely begun to arise, till, in the last scene of the First Act, Romeo the Montague sees Juliet the Capulet and becomes her slave.
