 the same words to others helps also to annex the ideas of the associated circumstances to them, and even of the passions themselves, both from the infectiousness of our natures, and from the power of associated circumstances to raise the passions. However, it is to be noted, that the words denoting the passions do not, for the most part, raise up in us any degree of the passions themselves, but only the ideas of the associated circumstances. We are supposed to understand the continued discourses into which these words enter sufficiently, when we form true notions of the actions, particularly the visible ones attending them.

Eleventhly, The names of intellectual and moral qualities and operations, such as fancy, memory, wit, dulness, virtue, vice, conscience, approbation, disapprobation, &c. stand for a description of these qualities and operations; and therefore, if dwelt upon, excite such ideas as these descriptions in all their particular circumstances do. But the common sentences, which these words enter, pass over the mind too quick, for the most part, to allow of such a delay. They are acknowledged as familiar and true, and suggest certain associated visible ideas, and nascent internal feelings, taken from the descriptions of these names, or from the words, which are usually joined with them in discourses or writings.

Twelfthly, There are many terms of art in all the branches of learning, which are defined by other words, and which therefore are only compendious substitutes for them. The same holds in common life in numberless instances. Thus riches, honours, pleasures, are put for the several kinds of each. Such words sometimes suggest the words of their definitions, sometimes the ideas of these words, sometimes a particular species comprehended under the general term, &c. But, whatever they suggest, it may be easily seen, that they derive the power of doing this from association.

Thirteenthly, There are many words used in abstract sciences, which can scarce be defined or described by any other words; and yet, by their grammatical form, seem to be excluded from the class of particles. Such are identity, existence, &c. The use of these must therefore be learnt as that of the particles is. And indeed children learn their first imperfect notions of all the words considered in this and the three last paragraphs chiefly in this way; and come to precise and explicit ones only by means of books, as they advance to adult age, or by endeavouring to use them properly in their own deliberate compositions.

This is by no means a full or satisfactory account of the ideas which adhere to words by association. For the author perceives himself to be still a mere novice in these speculations; and it is difficult to explain words to the bottom by words; perhaps impossible. The reader will receive some addition of light and evidence in the course of this section; also in the next, in which I shall treat of propositions and assent. For our assent to
