If words have all their possible extent of power, three effects arise in the mind of the hearer. The first is, the _sound_; the second, the _picture_, or representation of the thing signified by the sound; the third is, the _affection_ of the soul produced by one or by both of the foregoing. _Compounded abstract_ words, of which we have been speaking, (honor, justice, liberty, and the like,) produce the first and the last of these effects, but not the second. _Simple abstracts_ are used to signify some one simple idea without much adverting to others which may chance to attend it, as blue, green, hot, cold, and the like; these are capable of affecting all three of the purposes of words; as the _aggregate_ words, man, castle, horse, &c. are in a yet higher degree. But I am of opinion, that the most general effect, even of these words, does not arise from their forming pictures of the several things they would represent in the imagination; because, on a very diligent examination of my own mind, and getting others to consider theirs, I do not find that once in twenty times any such picture is formed, and when it is, there is most commonly a particular effort of the imagination for that purpose. But the aggregate words operate, as I said of the compound-abstracts, not by presenting any image to the mind, but by having from use the same effect on being mentioned, that their original has when it is seen. Suppose we were to read a passage to this effect: "The river Danube rises in a moist and mountainous soil in the heart of Germany, where, winding to and fro, it waters several principalities, until, turning into Austria, and laving the walls of Vienna, it passes into Hungary; there with a vast flood, augmented by the Save and the Drave, it quits Christendom, and rolling through the barbarous countries which border on Tartary, it enters by many mouths in the Black Sea." In this description many things are mentioned, as mountains, rivers, cities, the sea, &c. But let anybody examine himself, and see whether he has had impressed on his imagination any pictures of a river, mountain, watery soil, Germany, &c. Indeed it is impossible, in the rapidity and quick succession of words in conversation, to have ideas both of the sound of the word, and of the thing represented; besides, some words, expressing real essences, are so mixed with others of a general and nominal import, that it is impracticable to jump from sense to thought, from particulars to generals, from things to words, in such a manner as to answer the purposes of life; nor is it necessary that we should.
