A man should be learned in several sciences, and should have a reasonable, philosophical, and in some measure a mathematical head, to be a complete and excellent poet; and besides this, should have experience in all sorts of humours and manners of men; should be thoroughly skilled in conversation, and should have a great knowledge of mankind in general. Mr Settle having never studied any sort of learning but poetry, and that but slenderly, as you may find by his writings, and having besides no other advantages, must make very lame work on't; he himself declares, he neither reads, nor cares for conversation; so that he would persuade us he is a kind of fanatic in poetry, and has a light within him, and writes by an inspiration; which (like that of the heathen prophets) a man must have no sense of his own when he receives; and no doubt he would be thought inspired, and would be reverenced extremely in the country where Santons are worshipped. But some will, I doubt not, object, that poetry should not be reduced to the strictness of mathematics; to which I answer, it ought to be so far mathematical as to have likeness and proportion, since they will all confess that it is a kind of painting. But they will perhaps say, that a poem is a picture to be seen at a distance, and therefore ought to be bigger than the life. I confess there must be a due distance allowed for the seeing of any thing in the world; for an object can no more be seen at all too near, than too far off the eye: but granting that a poem is a picture to be viewed at a great distance, the distance and the bigness ought to be so suited, as though the picture be much bigger than the life, yet it must not seem so; and what miserable mistakes some poets make for want of knowing this truly, I leave to men of sense to judge; and by the way, let us consider that dramatic poetry, especially the English, brings the picture nearer the eye, than any other sort of poetry.
But some will say after this, what licence is left for poets? Certainly the same that good poets ever took, without being faulty, (for surely the best were so sometimes, because they were but men,) and that licence is fiction; which kind of poetry is like that of landscape-painting; and poems of this nature, though they be not vera, ought to be verisimilia.
The great art of poets is either the adorning and beautifying of truth, or the inventing pleasing and probable fictions. If they invent impossible fables, like some of Æsop's, they ought to have such morals couched under them, as may tend to the instruction of mankind, or the regulation of manners, or they can be of no use; nor can they really delight any but such as would be pleased with Tom Thumb, without these circumstances. But there are some pedants, who will quote authority from the ancients for the faults and extravagancies of some of the moderns; who being able to imitate nothing but the faults of the classic authors, mistake them for their excellencies. I speak with all due reverence to the ancients; for no man esteems their perfections more than myself, though I confess I have not that blind implicit faith in them which some ignorant schoolmasters would impose upon us, to believe in all their errors, and own all their crimes: to some pedants every thing in them is of that authority, that they will create a new figure of rhetoric out of the fault of an old poet. I am apt to believe the same faults were found in them, when they wrote, which men of sense find now; but not the excellencies which schoolmasters would persuade us: yet I must say now,
Nobis non licet esse tam disertis,
Musas qui colimus severiores.
