There are other rules more fixed and obligatory. It is necessary that of every play the chief action should be single; for since a play represents some transaction, through its regular maturation to its final event, two actions equally important must evidently constitute two plays. As the design of tragedy is to instruct by moving the passions, it must always have a hero, a personage apparently and incontestably superior to the rest, upon whom the attention may be fixed, and the anxiety suspended. For though, of two persons opposing each other with equal abilities and equal virtue, the auditor will inevitably, in time, choose his favourite, yet as that choice must be without any cogency of conviction, the hopes or fears which it raises will be faint and languid. Of two heroes acting in confederacy against a common enemy, the virtues or dangers will give little emotion, because each claims our concern with the same right, and the heart lies at rest between equal motives. It ought to be the first endeavour of a writer to distinguish nature from custom; or that which is established because it is right, from that which is right only because it is established; that he may neither violate essential principles by a desire of novelty, nor debar himself from the attainment of beauties within his view, by a needless fear of breaking rules which no literary dictator had authority to enact.

TO THE RAMBLER. SIR, Though one of your correspondents has presumed to mention with some contempt that presence of attention and easiness of address, which the polite have long agreed to celebrate and esteem, yet I cannot be persuaded to think them unworthy of regard or cultivation; but am inclined to believe that, as we seldom value rightly what we have never known the misery of wanting, his judgment has been vitiated by his happiness; and that a natural exuberance of assurance has hindered him from discovering its excellence and use. This felicity, whether bestowed by constitution, or obtained by early habitudes, I can scarcely contemplate without envy. I was bred under a man of learning in the country, who inculcated nothing but the dignity of knowledge, and the happiness of virtue. By frequency of admonition, and confidence of assertion, he prevailed upon me to believe, that the splendour of literature would always attract reverence, if not darkened by corruption. I therefore pursued my studies with incessant industry, and avoided every thing which I had been taught to consider either as vicious or tending to vice, because I regarded guilt and reproach as inseparably united, and thought a tainted reputation the greatest calamity.
