The office of philosophical disquisition consists in just distinction; while it is the privilege of the philosopher to preserve himself constantly aware, that distinction is not division. In order to obtain adequate notions of any truth, we must intellectually separate its distinguishable parts; and this is the technical process of philosophy. But having so done, we must then restore them in our conceptions to the unity, in which they actually co-exist; and this is the result of philosophy. A poem contains the same elements as a prose composition; the difference therefore must consist in a different combination of them, in consequence of a different object being proposed. According to the difference of the object will be the difference of the combination. It is possible, that the object may be merely to facilitate the recollection of any given facts or observations by artificial arrangement; and the composition will be a poem, merely because it is distinguished from prose by metre, or by rhyme, or by both conjointly. In this, the lowest sense, a man might attribute the name of a poem to the well-known enumeration of the days in the several months; “Thirty days hath September, April, June, and November,” etc. and others of the same class and purpose. And as a particular pleasure is found in anticipating the recurrence of sounds and quantities, all compositions that have this charm super-added, whatever be their contents, may be entitled poems. So much for the superficial form. A difference of object and contents supplies an additional ground of distinction. The immediate purpose may be the communication of truths; either of truth absolute and demonstrable, as in works of science; or of facts experienced and recorded, as in history. Pleasure, and that of the highest and most permanent kind, may result from the attainment of the end; but it is not itself the immediate end. In other works the communication of pleasure may be the immediate purpose; and though truth, either moral or intellectual, ought to be the ultimate end, yet this will distinguish the character of the author, not the class to which the work belongs. Blest indeed is that state of society, in which the immediate purpose would be baffled by the perversion of the proper ultimate end; in which no charm of diction or imagery could exempt the BATHYLLUS even of an Anacreon, or the ALEXIS of Virgil, from disgust and aversion!
