Thus does she, when from individual states Finally, good sense is the body of poetic genius, fancy its drapery, motion its life, and imagination the soul that is everywhere, and in each; and forms all into one graceful and intelligent whole. "A Defence of Poetry." ACCORDING SHELLEY The "Defence" was written at Pisa in 1821, in reply to an article by Peacock in Ollier's Literary Miscellany. It was intended to extend to three parts, only the first of which was completed. It was first published by Lady Shelley in the "Essays and Letters" in 1824. to one mode of regarding those two classes of mental action, which are called reason and imagination, the former may be con/sidered as mind contemplating the relations borne by one thought to another, however produced, and the latter, as mind acting upon those thoughts so as to colour them with its own light, and composing from them, as from elements, other thoughts, each containing within itself the principle of its own integrity. The one is the Tò Touw, or the principle of synthesis, and has for its objects those forms which are common to universal nature and existence itself; the other is the τὸ λογιζειν, or principle of analysis, and its action regards the relations of things simply as relations; considering thoughts, not in their integral unity, but as the algebraical representations which conduct to certain general results. Reason is the enumeration of qualities already known; imagination is the perception of the value of those quantities, both separately and as a whole. Reason respects the differences, and imagination the similitudes of things. Reason is to imagination as the instrument to the agent, as the body to the spirit, as the shadow to the substance. Poetry, in a general sense, may be defined to be "the expression of the imagination": and poetry is connate with the origin of man. Man is an instrument over which a series of external and internal impressions are driven, like the alternations of an ever- changing wind over an Æolian lyre, which move it by their motion to ever-changing melody. But there is a principle within the human being, and perhaps within all sentient beings, which acts otherwise than in the lyre, and produces not melody alone, but harmony, by an internal adjustment of the sounds or motions thus excited to the impressions which excite them. It is as if the lyre could accommodate its Ichords to the motions of that which strikes them, in a determined proportion of sound; even as the musician can accommodate his voice to the sound of the lyre. A child at play by itself will express its delight by its voice and motions and every inflexion of tone and every gesture will bear exact relation to a corresponding antitype in the pleasurable impressions which awakened it; it will be the reflected image of that impression; and as the lyre trembles and sounds after the wind has died away, so the child seeks, by prolonging in its voice and motions the duration of the effect, to prolong also a consciousness of the cause. In relation to the objects which delight a child, these expressions are, what poetry is to higher objects. The savage (for the savage is to ages what the child is to years) expresses the emotions produced in him by surrounding objects in a similar manner; and language and gesture, together with plastic or pictorial imitation, become the image of the combined effect of those objects, and of his apprehension of them. Man in society, with all his passions and his pleasures, next becomes the object of the passions and pleasures of man; an additional class of emotions produces an augmented treasure of expressions; and language, gesture, and the imitative arts, become at once the representation and the medium, the pencil and the picture, the chisel and the statue, the chord and the harmony. The social sympathies, or those laws from which, as from its elements, society results, begin to develop themselves from the moment that two human beings co-exist; the future is contained within the present, as the plant within the seed; and equality, diversity, unity, contrast, mutual dependence, become the principles alone capable of affording the motives according to which the will of a social being is determined to action, inasmuch as he is social; and constitute pleasure in sensation, virtue in sentiment, beauty in art, truth in reasoning, and love in the intercourse of kind. Hence men, even in the infancy of society, observe a certain order in their words and actions, distinct from that of the objects and the impressions represented by them, all expression being subject to the laws of that from which it proceeds. But let us dismiss those more general considerations which might involve an inquiry into the principles of society itself, and restrict our view to the manner in which the imagination is expressed upon its forms. In the youth of the world, men dance and sing and imitate natural objects, observing in these actions, as in all others, a certain rhythm or order. And, although all men observe a similar, they observe not the same order, in the motions of the dance, in the melody of the song, in the combinations of language, in the series of their imitations of natural objects. For there is a certain order or rhythm belonging to each of these classes of mimetic representation, from which the hearer and the spectator receive an intenser and purer pleasure than from any other: the sense of an approximation to this order has been called taste by modern writers. Every man in the infancy of art, observes an order which approximates more or less closely to that from which this highest delight results: but the diversity is not sufficiently marked, as that its gradations should be sensible, except in those instances where the predominance of this faculty of approximation to the beautiful (for |
