EFFECT OF WORDS.
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 (honour, 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 effecting all three of the purposes of words; as the AGGREGATE words, man, castle, horse, etc. 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.
INVESTIGATION.
I am convinced that the method of teaching which approaches most nearly to the method of investigation is incomparably the best; since, not content with serving up a few barren and lifeless truths, it leads to the stock on which they grew; it tends to set the reader himself in the track of invention, and to direct him into those paths in which the author has made his own discoveries, if he should be so happy as to have made any that are valuable.
THE SUBLIME.
Whatever is fitted in any sort to excite the ideas of pain, and danger, that is to say, whatever is in any sort terrible, or is conversant about terrible objects, or operates in a manner analogous to terror, is a source of the SUBLIME; that is, it is productive of the strongest emotion which the mind is capable of feeling.
