(2) If we turn now from the differences of tension to the sequence of events within the conflict, we shall find the principle of alternation at work again in another and a quite independent way. Let us for the sake of brevity call the two sides in the conflict A and B. Now, usually, as we shall see presently, through a considerable part of the play, perhaps the first half, the cause of A is, on the whole, advancing; and through the remaining part it is retiring, while that of B advances in turn. But, underlying this broad movement, all through the conflict we shall find a regular alternation of smaller advances and retirals; first A seeming to win some ground, and then the counter-action of B being shown. And since we always more or less decidedly prefer A to B or B to A, the result of this oscillating movement is a constant alternation of hope and fear, or rather of a mixed state predominantly hopeful and a mixed state predominantly apprehensive. An example will make the point clear. In Hamlet the conflict begins with the hero's feigning to be insane from disappointment in love, and we are shown his immediate success in convincing Polonius. Let us call this an advance of A. The next scene shows the King's great uneasiness about Hamlet's melancholy, and his scepticism as to Polonlus's explanation of its cause: advance of B. Hamlet completely baflles Rosencrantz and Guildenstern, who have been sent to discover his secret, and he arranges for the test of the play-scene: advance of A. But immediately before the play-scene his soliloquy on suicide fills us with misgiving; and his words to Ophelia, overheard, so convince the King that love is not the cause of his nephew's strange behaviour, that he determines to get rid of him by sending him to England: advance of B. The play-scene proves a complete success: decided advance of A. Directly after it Hamlet spares the King at prayer, and in an interview with his mother un-
