Any pleasure we have in an agreeable object of this kind, is enjoyed by the continuance of the pleasant impression it makes upon us; and accordingly the desire involved in the pleasant emotion tends to that end, and is gratified by dwelling upon the agreeable object. Hence such an object may be properly termed _attractive_. Thus a flowing river, a towering hill, a fine garden, are attractive objects. They fix the attention of the spectator, by inspiring pleasant emotions, which are gratified by adhering to these objects and enjoying them. On the other hand, a disagreeable object of the same kind, raises in us a painful emotion including a desire to turn from the object, which relieves us of course from the pain; and hence such an object may be properly termed _repulsive_. A monstrous birth, for example, a rotten carcass, a confusion of jarring sounds, are repulsive. They repel the mind, by inspiring painful or unpleasant emotions, which are gratified by flying from such objects. Thus in general, with regard to inanimate objects, the desire included in every pleasant passion tends to prolong the pleasure, and the desire included in every painful passion tends to put an end to the pain. Here the final cause is evident. Our desires, so far, are modelled in such a manner as to correspond precisely to the sensitive part of our nature, prone to happiness and averse to misery. These operations of adhering to an agreeable inanimate object, and flying from one that is disagreeable, are performed in the beginning of life by means of desire impelling us, without the intervention of reason or reflection. Reason and reflection directing self-love, become afterward motives that unite their force with desire; because experience informs us, that the adhering to agreeable objects and the flying from those that are disagreeable, contribute to our happiness.
