 particular, is the uncertainty and difficulty we have only in comparing them with one another. In looking at a line an inch long, I have a certain general impression of it, so that I can tell it is shorter than another, three or four times as long, drawn on the same sheet of paper, but I cannot immediately tell that it is shorter than one only a tenth or twentieth of an inch longer. The idea which I have of it is therefore not an exact one. In looking at a window I cannot precisely tell the number of panes of glass it contains, yet I can easily say whether they are few or many, whether the window is large or small. Now if all our ideas were made up of particulars, we never could pronounce generally whether there were few or many of these panes of glass, but we should know the precise number, or at least pitch on some precise number in our minds, and this we could not help knowing. There must be either 5, 10, 20, or 30; for it is in vain to urge that the idea in my mind is a floating one, and shifts from one of them to another, so that I cannot tell the moment after which it was; but what is this imperfect recollection but a confused contradictory and abstract idea? Here is a plain dilemma: it is a fact that we have some idea of a number of objects presented to us. It is also a fact that we do not know the precise number, nor can we assign any number confidently whether right or wrong. Whether this idea is but an abstract and general one it seems hard to say. Those who contend that we cannot have an idea of a man in general, without conceiving of some particular man, seem to have little reason, since the most particular idea we can form of a man, either in imagination or from the actual impression, is but a general idea. Those who say we cannot conceive of an army of men without conceiving of the individuals composing it, ought to go a step further, and affirm that we
