Read it through once

Likewise, when Anonymous considers unity his emphasis, like Johnson's and Hurd's, is no longer on the mechanical unities but on unity of design. "When Shakespeare's plan is understood most of the criticisms of Rymer and Voltaire vanish away," Johnson was to write some thirty years later. Anonymous holds steadily for the integrity of Shakespeare's plan in Hamlet. Of Act I, iii he says, "Concerning the Design of this scene, we shall find it is necessary towards the whole plot of the Play"; he speaks of I, iv as an "important Scene, on which turns the Whole Play"; the killing of Polonious, he explains, "was in Conformity to the Plan _Shakespeare_ built his Play upon"; and finally, of the piece as a whole, he asserts that "there is not one Scene but what some way or other conduces toward the _Denoument_ of the Whole; and thus the Unity of Action is indisputably kept up by everything tending to what we may call the main Design, and it all hangs by Consequence so close together, that no Scene can be omitted, without Prejudice to the Whole." When one recalls that the idea of unity of design as evolved in Thomas Warton, Hurd, and Johnson was the intermediate step on the way to a full theory of organic unity we see the importance of such passages in the forward march of criticism.
