The Kind of Picture, or Drawing having been consider’d, regard is to be had to the Parts of Painting ; we should see in which of These they excell, and in what Degree.
And these several Parts do not Equally contribute to the Ends of Painting : but (I think) ought to stand in this Order.

Grace and Greatness,
Invention,
Expression,
Composition,
Colouring,
Drawing,
Handling.

The last can only Please ; The next (by which I understand Pure Nature, for the Great, and Gentile Style of Drawing falls into another Part) This also can only Please, Colouring Pleases more ; Composition Pleases at least as much as Colouring, and moreover helps to Instruct, as it makes those Parts that do so more conspicuous ; Expression Pleases, and Instructs Greatly ; the Invention does both in a higher Degree, and Grace, and Greatness above all. Nor is it peculiar to That Story, Fable, or whatever the Subject is, but in General raises our Idea of the Species, gives a most Delightful, Vertuous Pride, and kindles in Noble Minds an Ambition to act up to That Dignity Thus conceived to be in Humane Nature. In the Former Parts the Eye is employ’d, in the Other the Understanding.

HANDLING
BY this Term is understood the manner in which the Colours are left by the Pencil upon the Picture ; as the manner of using the Pen, Chalk, or Pencil in a Drawing is the Handling of that Drawing.
This consider’d in it self abstractedly is only a piece of Mechanicks, and is Well, or Ill as ‘tis perform’d with a Curious, Expert ; or Heavy, Clumsey Hand ; and that whether ‘tis Smooth, or Rough, or however ‘tis done ; for all the Manners of Working the Pencil may be Well or Ill in their kind ; and a fine light Hand is seen as much in a Rough, as in a Smooth manner.

PAINTING is indeed a Difficult Art, productive of Curious pieces of Workmanship, and greatly Ornamental ; and its Business is to represent Nature. Thus far the Common Idea is just ; Only that ‘tis More Difficult, More Curious, and More Beautifull than is Commonly Imagin’d.
‘Tis an entertaining thing to the Mind of Man to see a fine piece of Art in Any kind ; and every one is apt to take a sort of Pride in it as being done by one of his Own Species, to whom with respect to the Universe he stands related as to one of the Same Countrey, or the Same Family. Painting affords us a great Variety of This kind of Pleasure in the Delicate, or Bold management of the Pencil ; in the mixture of its Colours, in the Skilful Contrivance of the several parts of the Picture, and infinite Variety of the Tincts, so as to produce Beauty, and Harmony. This alone gives great Pleasure to those who have learn’d to see these things.

The more Remote any thing is supposed to be, the less Finishing it ought to have. I have seen a Fringe to a Curtain in the Back-Ground of a Picture, which perhaps was half a Day in painting, but might have been better done in a Minute.
There is often a Spirit, and Beauty in a Quick, or perhaps an Accidental Management of the Chalk, Pen, Pencil, or Brush in a Drawing, or Painting, which ‘tis impossible to preserve if it be more finish’d ; at least ‘tis great odds but it will be lost : ‘Tis better therefore to incur the Censure of the Injudicious than to hazard the losing such Advantages to the Picture. Apelles comparing himself with Protogenes said, Perhaps he is Equal, if not Superior to me in Some things, but I am sure I Excell him in This : I know when to have done.
