“Nothing is more familiar to experience, than the sentiment of joy: this sentiment, which is only momentary in man, gives him some idea of a more real felicity, whereof that which he feels is only a specimen or sample. From this experience he concludes, that the Author of his being, having made him capable of so delicious a sentiment, must be the source of all felicity.
Another thing, which he feels, leads him still farther: I mean the invincible inclination he has to happiness; and, as this desire is inseparable to his being, it must likewise be ascribed to the author of his being; from whence he justly concludes, that happiness is the end of his being. This conclusion leads him to another: he finds it is not completely attained in this world, consequently there must be one hereafter which will accomplish that end.”
