 posed with the vulgar that it was only necessary to open the eyes in order to see, and that the images produced by outward objects are completely defined, and unalterable things, in which there can be no dimness and confusion. These speculators had no thought but they saw as much of a landscape as Poussin, and knew as much about a face that was before them as Titian or Vandyke would have done. This is a great mistake; the having particular and absolute ideas of things is not only difficult, but impos⇗sible. The ablest painters have never been able to give more than one part of nature, in abstracted views of things. The most laborious artists never finished to perfection any one part of an object, or had ever any more than a confused, vague, uncertain notion of the shape of the mouth or nose, or the colour of an eye. Ask a logician, or any common man, and he will no doubt tell you that a face is a face, a nose is a nose, a tree is a tree, and that he can see what it is as well as another. Ask a painter and he will tell you otherwise. Secondly, when it is asserted that we must necessarily have the idea of a particular sign, when we think of any in general, all that is intended by it is, I believe, that we must think of a particular height. This idea it is supposed must be particular and determinate, just as we must draw a line with a piece of chalk, or make a mark with the slides of a measuring rule, in one place and not in the other. I think it may be shewn that this view of the question is also utterly fallacious, and out of the order of our ideas. The height of the individual is thus resolved with the ideas of the lines terminating or defining it, and the intermediate space of which it properly consists is entirely forgotten. For let us take any given height of a man, whether tall, short, or middle-sized, and let that height be as visible as you
