Dissecting the Rural Vista

I. Pleasures of the senses

1. The simple pleasures of sight, excited by the perception of agreeable colours and figures, green fields, waving foliage, glistening water, and the like.
2. The simple pleasures of the ear, excited by the perceptions of the chirping of birds, the murmuring of waters, the rustling of the wind among the trees.
3. The pleasures of the smell, excited by the perceptions of the fragrance of flowers, of new-mown hay, or other vegetable substances, in the first stages of fermentation.
4. The agreeable inward sensation, produced by a brisk circulation of the blood, and the ventilation of it in the lungs by a pure air, such as that in the country frequently is in comparison of that which is breathed in towns.

II. Pleasures of the imagination produced by association

1. The idea of the plenty, resulting from the possession of the objects that are in view, and of the happiness arising from it.
2. The idea of the innocence and happiness of the birds, sheep, cattle, dogs, and other gentle or domestic animals.
3. The idea of the constant flow of health, supposed to be enjoyed by all these creatures: a notion which is apt to result from the occasional flow of health enjoyed by the supposed spectator.
4. The idea of gratitude, excited by the contemplation of the all powerful and beneficent Being, who is looked up to as the author of these blessings.
