It engages them to contemplate the Creator in his works; it purifies and harmonizes the soul, and prepares it for moral and intellectual discipline; it supplies an endless source of amusement, it recommends virtue for its transcendent loveliness, and makes vice appear the object of contempt and abomination. Compared with these genuine delights, how trivial and unworthy, to susceptible minds, must appeal the steams and noise of a ball-room, the insipidities of an opera, or the vexations and wranglings of a card-table.—Preface.
