Of all the arts _poetry_ (which owes its origin almost entirely to genius and will least be guided by precept or example) maintains the first rank. It expands the mind by setting the Imagination at liberty; and by offering within the limits of a given concept amid the unbounded variety of possible forms accordant therewith, that which unites the presentment of this concept with a wealth of thought, to which no verbal expression is completely adequate; and so rising aesthetically to Ideas. It strengthens the mind by making it feel its faculty--free, spontaneous and independent of natural determination--of considering and judging nature as a phenomenon in accordance with aspects which it does not present in experience either for Sense or Understanding, and therefore of using it on behalf of, and as a sort of schema for, the supersensible. It plays with illusion, which it produces at pleasure, but without deceiving by it; for it declares its exercise to be mere play, which however can be purposively used by the Understanding.--Rhetoric, in so far as this means the art of persuasion, _i.e._ of deceiving by a beautiful show (_ars oratoria_), and not mere elegance of speech (eloquence and style), is a Dialectic, which borrows from poetry only so much as is needful to win minds to the side of the orator before they have formed a judgement, and to deprive them of their freedom; it cannot therefore be recommended either for the law courts or for the pulpit. For if we are dealing with civil law, with the rights of individual persons, or with lasting instruction and determination of people’s minds to an accurate knowledge and a conscientious observance of their duty, it is unworthy of so important a business to allow a trace of any exuberance of wit and imagination to appear, and still less any trace of the art of talking people over and of captivating them for the advantage of any chance person. For although this art may sometimes be directed to legitimate and praiseworthy designs, it becomes objectionable, when in this way maxims and dispositions are spoiled in a subjective point of view, though the action may objectively be lawful. It is not enough to do what is right; we should practise it solely on the ground that it is right. Again, the mere concept of this species of matters of human concern, when clear and combined with a lively presentation of it in examples, without any offence against the rules of euphony of speech or propriety of expression, has by itself for Ideas of Reason (which collectively constitute eloquence), sufficient influence upon human minds; so that it is not needful to add the machinery of persuasion, which, since it can be used equally well to beautify or to hide vice and error, cannot quite lull the secret suspicion that one is being artfully overreached. In poetry everything proceeds with honesty and candour. It declares itself to be a mere entertaining play of the
