In a natural landscape, we every day perceive a multitude of objects connected by contiguity solely. Objects of sight make an impression so lively, as that a relation, even of the slightest kind, is relished. This however ought not to be imitated in description. Words are so far short of the eye in liveliness of impression, that in a description the connection of objects ought to be carefully studied, in order to make the deeper impression. For it is a known fact, the reason of which is suggested above, that it is easier by words to introduce into the mind a related object, than one which is not connected with the preceding train. In the following passage, different things are brought together without the slightest connection, if it be not what may be called verbal, _i. e._ taking the same word in different meanings. Surgamus: solet esse gravis cantantibus umbra. Juniperi gravis umbra: nocent et frugibus umbræ. Ite domum saturæ, venit Hesperus, ite capellæ. _Virg. Buc._ 10. 75. The metaphorical or figurative appearance of an object, is no good cause for introducing that object in its real and natural appearance. A relation so slight can never be relished. Distrust in lovers is too warm a sun; But yet ’tis night in love when that is gone. And in those climes which most his scorching know, He makes the noblest fruits and metals grow. _Part_ 2. _Conquest of Granada_, _act_ 3. The relations among objects have a considerable influence in the gratification of our passions, and even in their production. But this subject is reserved to be treated in the chapter of emotions and passions[13]. There is perhaps not another instance of a building so great erected upon a foundation so slight in appearance, as that which is erected upon the relations of objects and their arrangement. Relations make no capital figure in the mind: the bulk of them are transitory, and some extremely trivial. They are however the links that, uniting our perceptions into one connected chain, produce connection of action, because perceptions and actions have an intimate correspondence. But it is not sufficient for the conduct of life that our actions be linked together, however intimately: it is beside necessary that they proceed in a certain order; and this also is provided for by an original propensity. Thus order and connection, while they admit sufficient variety, introduce a method in the management of affairs. Without them our conduct would be fluctuating and desultory; and we would be hurried from thought to thought, and from action to action, entirely at the mercy of chance. CHAP. II.
