I forbear to speak of an incongruity which would shock the intelligent Reader, should the Poet interweave any foreign splendour of his own with that which the passion naturally suggests: it is sufficient to say that such addition is unnecessary.

And, surely, it is more probable that those passages, which with propriety abound with metaphors and figures, will have their due effect, if, upon other occasions where the passions are of a milder character, the style also be subdued and temperate.
But, as the pleasure which I hope to give by the Poems now presented to the Reader must depend entirely on just notions upon this subject, and, as it is in itself of high importance to our taste and moral feelings, I cannot content myself with these detached remarks.

And if, in what I am about to say, it shall appear to some that my labour is unnecessary, and that I am like a man fighting a battle without enemies, such persons may be reminded, that, whatever be the language outwardly holden by men, a practical faith in the opinions which I am wishing to establish is almost unknown.

If my conclusions are admitted, and carried as far as they must be carried if admitted at all, our judgements concerning the works of the greatest Poets both ancient and modern will be far different from what they are at present, both when we praise, and when we censure: and our moral feelings influencing and influenced by these judgements will, I believe, be corrected and purified.
Taking up the subject, then, upon general grounds, let me ask, what is meant by the word Poet?
What is a Poet?
To whom does he address himself?
And what language is to be expected from him ?--He is a man speaking to men: a man, it is true, endowed with more lively sensibility, more enthusiasm and tenderness, who has a greater knowledge of human nature, and a more comprehensive soul, than are supposed to be common among mankind; a man pleased with his own passions and volitions, and who rejoices more than other men in the spirit of life that is in him; delighting to contemplate similar volitions and passions as manifested in the goings-on of the Universe, and habitually impelled to create them where he does not find them.
To these qualities he has added a disposition to be affected more than other men by absent things as if they were present; an ability of conjuring up in himself passions, which are indeed far from being the same as those produced by real events, yet (especially in those parts of the general sympathy which are pleasing and delightful) do more nearly resemble the passions produced by real events, than anything which, from the motions of their own minds merely, other men are accustomed to feel in themselves:--whence, and from practice, he has acquired a greater readiness and power in expressing what he thinks and feels, and especially those thoughts and feelings which, by his own choice, or from the structure of his own mind, arise in him without immediate external excitement.
But whatever portion of this faculty we may suppose even the greatest Poet to possess, there cannot be a doubt that the language which it will suggest to him, must often, in liveliness and truth, fall short of that which is uttered by men in real life, under the actual pressure of those passions, certain shadows of which the Poet thus produces, or feels to be produced, in himself.
However exalted a notion we would wish to cherish of the character of a Poet, it is obvious, that while he describes and imitates passions, his employment is in some degree mechanical, compared with the freedom and power of real and substantial action and suffering.

So that it will be the wish of the Poet to bring his feelings near to those of the persons whose feelings he describes, nay, for short spaces of time, perhaps, to let himself slip into an entire delusion, and even confound and identify his own feelings with theirs; modifying only the language which is thus suggested to him by a consideration that he describes for a particular purpose, that of giving pleasure.
