The celebrity of the great classical writers is confined within no limits, except those which separate civilised from savage man. Their works are the common property of every polished nation. They have furnished subjects for the painter, and models for the poet. In the minds of the educated classes throughout Europe, their names are indissolubly associated with the endearing recollections of childhood,--the old school-room,--the dog-eared grammar,--the first prize,--the tears so often shed and so quickly dried. So great is the veneration with which they are regarded, that even the editors and commentators who perform the lowest menial offices to their memory, are considered, like the equerries and chamberlains of sovereign princes, as entitled to a high rank in the table of literary precedence. It is, therefore, somewhat singular that their productions should so rarely have been examined on just and philosophical principles of criticism. The ancient writers themselves afford us but little assistance. When they particularise, they are commonly trivial: when they would generalise, they become indistinct. An exception must, indeed, be made in favour of Aristotle. Both in analysis and in combination, that great man was without a rival. No philosopher has ever possessed, in an equal degree, the talent either of separating established systems into their primary elements, or of connecting detached phenomena in harmonious systems. He was the great fashioner of the intellectual chaos; he changed its darkness into light, and its discord into order. He brought to literary researches the same vigour and amplitude of mind to which both physical and metaphysical science are so greatly indebted. His fundamental principles of criticism are excellent. To cite only a single instance:--the doctrine which he established, that poetry is an imitative art, when justly understood, is to the critic what the compass is to the navigator. With it he may venture upon the most extensive excursions. Without it he must creep cautiously along the coast, or lose himself in a trackless expanse, and trust, at best, to the guidance of an occasional star. It is a discovery which changes a caprice into a science.
