"A talent for lively description, at least in the case of sensible objects, depends chiefly on the degree in which the describer possesses the power of conception. We may remark, even in common conversation, a striking difference among individuals in this respect. One man, in attempting to convey a notion of any object he has seen, seems to place it before him, and to paint from actual perception; another, although not deficient in a ready elocution, finds himself, in such a situation, confused and embarrassed among a number of particulars imperfectly apprehended, which crowd into his mind without any just order and connection. Nor is it merely to the accuracy of our descriptions that this power is subservient; it contributes, more than any thing else, to render them striking and expressive to others, by guiding us to a selection of such circumstances as are most prominent and characteristic; insomuch that I think it may reasonably be doubted if a person would not write a happier description of an object from the conception than from the perception of it. It has often been remarked, that the perfection of description does not consist in a minute specification of circumstances, but in a judicious selection of them and that the best rule for making the selection is to attend to the particulars that make the deepest impression on our own minds. When the object is actually before us, it is extremely difficult to compare the impressions which different circumstances produce; and the very thought of writing a description, would prevent the impressions which would otherwise take place. When we afterward conceive the object, the representation of it we form to ourselves, however lively, is merely an outline, and is made up of those circumstances which really struck us most at the moment, while others of less importance are obliterated." _Conceptions often Complex._--It is to be further remarked respecting the power now under consideration, that the notion, or conception which we form of an object, by means of this faculty, is frequently complex. The particular perceptions and sensations formerly experienced, and now represented, are combined, forming thus a notion of the object as a whole. The figure, magnitude, color, and various other properties, of any object, as, _e. g._, a table, are objects each of distinct and separate cognition, and as such are mentally reproduced, distinctly, and separately; but when thus reproduced, are combined to form the complete conception of the table, as it lies in my mind. The notion or conception of the object as a whole being thus once formed, any single perception as, _e. g._, of color, figure, etc., is afterward sufficient to recall and represent the whole.
