That this is a practice contrary to the rules of criticism will be readily allowed; but there is always an appeal open from criticism to nature. The end of writing is to instruct; the end of poetry is to instruct by pleasing. That the mingled drama may convey all the instruction of tragedy or comedy cannot be denied, because it includes both in its alterations of exhibition, and approaches nearer than either to the appearance of life, by shewing how great machinations and slender designs may promote or obviate one another, and the high and the low co-operate in the general system by unavoidable concatenation.
( Samuel Johnson )
[ Preface to Shakespeare ]
