We will, however, hear a poet's defence of his fraternity:--'Poets are vulgarly considered deficient in the reasoning faculty; whereas no man was ever a great poet without having it in excess, and after a century or two, men become convinced of it. They jump the middle terms of their syllogisms, it is true, and assume premises to which the world has not yet arrived; but time stamps their deductions as invincible.'* Imagination is based on observation, and bears the same relation to the 'material world' that the magician bears to the appliances of his art. Imagination is the dexterous and astonishing use of realities. It is a species of mental experiment, whereby, without permission of the line-and-rule men, we join strange things together, and to the surprise of every body, the junction is a happy one. 'Angelo's greatness lay in searching for untried existence.'** But observation primarily suggests the combination. If, as in the case of Angelo, imagination essays the highest flights of genius, and goes in search of untried existence, it is not existence out of nature, but founded upon nature--its success is a revelation of some hidden reality. * Lowell's Conversations on the Old Poets. ** J. T. Seymour; Oracle of Reason. Some of the most praised conceptions of Shakspere have been traced by critics to the tritest observation. Instance Hamlet's remark:-- There's a divinity doth shape our ends, Bough-hew them as we will. Critics tell us, that Shakspere here fell into the conventional cant of a mechanic making skewers. But it is no detraction to cull the best phrases from the most common sources. Knight remarks:--'Philosophy, as profound as it is beautiful! says the uninitiated reader of Shakspere. But he that is endued with the wisdom of the commentators, will learn how easy it is to mistake for philosophy and poetry what really only proceeded from the very vulgar recollection of an ignorant mind. Dr. Farmer informs me, says Steevens, that these words are merely technical. A woodman, butcher, and dealer in skewers, lately observed to him, that his nephew (an idle lad), could only assist in making them; he could rough-hew them, but I was obliged to shape their ends. To shape the ends of wood skewers, i. e., to point them, requires a degree of skill: any one can rough-hew them. Whoever recollects the profession of Shakspere's father, will admit that his son might be no stranger to such terms. I have frequently seen packages of wool pinned up with skewers.'* To admit the likelihood of all this, notwithstanding Mr. Knight's jeer at the 'wisdom of the commentators,' is rather to exalt than degrade the genius of Shakspere, who could derive exalted figures from humble sources. The 'Athenaeum,' far more wisely than Mr. Knight, in this instance, observes:--'This is the test of a truly great man; that his thoughts should be _things_, and become things in instantaneous act, and not for a moment mere speculations and abstractions.'
