Read it through once

But I digress.--The connexion of scenic exhibitions with the improvement or corruption of the manners of men, has been universally recognized: in other words, the presence or absence of poetry in its most perfect and universal form, has been found to be connected with good and evil in conduct or habit. The corruption which has been imputed to the drama as an effect, begins when the poetry employed in its constitution ends: I appeal to the history of manners whether the periods of the growth of the one and the decline of the other have not corresponded with an exactness equal to any example of moral cause and effect.
