I never was an admirer of machinery in an epic poem; and I now find my taste justified by reason; the foregoing argument concluding still more strongly against imaginary beings, than against improbable facts. Fictions of this nature may amuse by their novelty and singularity: but they never move the sympathetic passions, because they cannot impose on the mind any perception of reality. I appeal to the discerning reader, whether this be not precisely the case of the machinery introduced by Tasso and by Voltaire. This machinery is not only in itself cold and uninteresting, but is remarkably hurtful, by giving an air of fiction to the whole composition. A burlesque poem, such as the Lutrin or the Dispensary, may employ machinery with success; for these poems, though they assume the air of history, give entertainment chiefly by their pleasant and ludicrous pictures, to which machinery contributes in a singular manner. It is not the aim of such a poem, to raise our sympathy in any considerable degree; and for that reason, a strict imitation of nature is not required. A poem professedly ludicrous, may employ machinery to great advantage; and the more extravagant the better. A just representation of nature, would indeed be incongruous in a composition intended to give entertainment by the means chiefly of singularity and surprise. For accomplishing the task undertaken in the beginning of the present section, what only remains is, to show the final cause of the power that fiction hath over the mind of man. I have already mentioned, that language, by means of fiction, has the command of our sympathy for the good of others. By the same means, our sympathy may be also raised for our own good. In the third section it is observed, that examples both of virtue and of vice raise virtuous emotions; which becoming stronger by exercise, tend to make us virtuous by habit as well as by principle. I now further observe, that examples drawn from real events, are not so frequent as to contribute much to a habit of virtue. If they be, they are not recorded by historians. It therefore shows great wisdom, to form us in such a manner, as to be susceptible of the same improvement from fable that we receive from genuine history. By this admirable contrivance, examples to improve us in virtue may be multiplied without end. No other sort of discipline contributes more to make virtue habitual; and no other sort is so agreeable in the application. I add another final cause with thorough satisfaction; because it shows, that the author of our nature is not less kindly provident for the happiness of his creatures, than for the regularity of their conduct. The power that fiction hath over the mind of man, is the source of an endless variety of refined amusement, always ready to employ a vacant hour. Such amusement is a fine resource in solitude; and by sweetening the temper, improves society. PART II.
