He may be allowed sometimes to err, who undertakes to move so many Characters and Humours (as are requisite in a Play) in those narrow channels, which are proper to each of them; to conduct his Imaginary Persons through so many various intrigues and chances, as the labouring Audience shall think them lost under every billow: and then, at length, to work them so naturally out of their distresses, that when the whole Plot is laid open, the Spectators may rest satisfied that every Cause was powerful enough to produce the Effect it had; and that the whole Chain of them was, with such due order, linked together, that the first Accident [Incident], would, naturally, beget the second, till they All rendered the Conclusion necessary.
These difficulties, my Lord! may reasonably excuse the errors of my Undertaking: but for this confidence of my Dedication, I have an argument, which is too advantageous for me not to publish it to the World. 'Tis the kindness your Lordship has continually shown to all my writings. You have been pleased, my Lord! they should sometimes cross the Irish seas, to kiss your hands; which passage, contrary to the experience of others, I have found the least dangerous in the world. Your favour has shone upon me, at a remote distance, without the least knowledge of my person: and, like the influence of the heavenly bodies, you have done good, without knowing to whom you did it, 'Tis this virtue in your Lordship, which emboldens me to this attempt. For did I not consider you as my Patron, I have little reason to desire you for my Judge: and should appear, with as much awe before you, in the Reading; as I had, when the full theatre sate upon the Action.
For who so severely judge of faults, as he who has given testimony he commits none? Your excellent Poems having afforded that knowledge of it to the World, that your enemies are ready to upbraid you with it as a crime, for a Man of Business to write so well. Neither durst I have justified your Lordship in it, if examples of it had not been in the world before you: If XENOPHON had not written a Romance; and a certain Roman, called AUGUSTUS CAESAR, a Tragedy and Epigrams. But their writing was the entertainment of their pleasure; yours is only a diversion of your pain. The Muses have seldom employed your thoughts, but when some violent fit of the gout has snatched you from Affairs of State: and, like the priestess of APOLLO, you never come to deliver his oracles, but unwillingly, and in torment. So that we are obliged to your Lordship's misery, for our delight. You treat us with the cruel pleasure of a Turkish triumph, where those who cut and wound their bodies, sing songs of victory as they pass; and divert others with their own sufferings. Other men endure their diseases, your Lordship only can enjoy them!
Plotting and Writing in this kind, are, certainly, more troublesome employments than many which signify more, and are of greater moment in the world. The Fancy, Memory, and Judgement are then extended, like so many limbs, upon the rack; all of them reaching, with their utmost stress, at Nature: a thing so almost infinite and boundless, as can never fully be comprehended but where the Images of all things are always present.
Yet I wonder not your Lordship succeeds so well in this attempt. The knowledge of men is your daily practice in the world. To work and bend their stubborn minds; which go not all after the same grain, but, each of them so particular a way, that the same common humours, in several persons, must be wrought upon by several means.
Thus, my Lord! your sickness is but the imitation of your health; the Poet but subordinate to the Statesman in you. You still govern men with the same address, and manage business with the same prudence: allowing it here, as in the world, the due increase and growth till it comes to the just height; and then turning it, when it is fully ripe, and Nature calls out (as it were) to be delivered. With this only advantage of ease to you, in your Poetry: that you have Fortune, here, at your command: with which, Wisdom does often unsuccessfully struggle in the world. Here is no Chance, which you have not foreseen. All your heroes are more than your subjects, they are your creatures: and, though they seem to move freely, in all the sallies of their passions; yet, you make destinies for them, which they cannot shun. They are moved, if I may dare to say so, like the rational creatures of the Almighty Poet; who walk at liberty, in their own opinion, because their fetters are invincible: when, indeed, the Prison of their Will is the more sure, for being large; and instead of an Absolute Power over their actions, they have only a Wretched Desire of doing that, which they cannot choose but do.
I have dwelt, my Lord! thus long, upon your Writing; not because you deserve not greater and more noble commendations, but because I am not equally able to express them in other subjects. Like an ill swimmer, I have willingly stayed long in my own depth; and though I am eager of performing more, yet I am loath to venture out beyond my knowledge. For beyond your Poetry, my Lord! all is Ocean to me.
To speak of you as a Soldier, or a Statesman, were only to betray my own ignorance: and I could hope no better success from it, than that miserable Rhetorician had, who solemnly declaimed before HANNIBAL "of the Conduct of Armies, and the Art of War." I can only say, in general, that the Souls of other men shine out at little cranies; they understand some one thing, perhaps, to admiration, while they are darkened on all the other parts: but your Lordship's Soul is an entire Globe of Light, breaking out on every side; and if I have only discovered one beam of it, 'tis not that the light falls unequally, but because the body which receives it, is of unequal parts.
The acknowledgement of which, is a fair occasion offered me, to retire from the consideration of your Lordship to that of myself. I here present you, my Lord! with that in Print, which you had the goodness not to dislike upon the Stage; and account it happy to have met you here in England: it being, at best, like small wines, to be drunk out upon the place [i.e., of vintage, where produced]; and has not body enough to endure the sea.
I know not, whether I have been so careful of the Plot and Language, as I ought: but for the latter, I have endeavoured to write English, as near as I could distinguish it from the tongue of pedants, and that of affected travellers. Only, I am sorry that, speaking so noble a language as we do, we have not a more certain Measure of it, as they have in France: where they have an "Academy" erected for that purpose, and endowed with large privileges by the present King [LOUIS XIV.]. I wish, we might, at length, leave to borrow words from other nations; which is now a wantonness in us, not a necessity: but so long as some affect to speak them, there will not want others who will have the boldness to write them.
