ABSTRACT
There is a sort of improbability with which we are shocked in dramatic representation, not less than in a narrative of real life. Consequently, there must be rules respecting it; and as rules are nothing but means to an end previously ascertained—(inattention to which simple truth has been the occasion of all the pedantry of the French school),—we must first determine what the immediate end or object of the drama is. And here, as I have previously remarked, I find two extremes of critical decision;—the French, which evidently presupposes that a perfect delusion is to be aimed at,—an opinion which needs no fresh confutation; and the exact opposite to it, brought forward by Dr. Johnson, who supposes the auditors throughout in the full reflective knowledge of the contrary. In evincing the impossibility of delusion, he makes no sufficient allowance for an intermediate state, which I have before distinguised by the term, illusion, and have attempted to illustrate its quality and character by reference to our mental state, when dreaming. In both cases we simply do not judge the imagery to be unreal; there is a negative reality, and no more. Whatever, therefore, tends to prevent the mind from placing itself, or being placed, gradually in that state in which the images have such negative reality for the auditor, destroys this illusion, and is dramatically improbable.
