Essentially practical, as we have observed, in his mind, De Foe was ever anxious to give useful instructions to his countrymen, for the regulation of their conduct in their homes and their pursuits in life, and embodied the results of an experienced and sagacious mind in the Family Instructor, the Religious Courtship, and the Complete English Tradesman. This last work is one which no young man entering into business should be without. It is an invaluable manual, full of the lessons of instructed prudence and good sense. Even his admirable romances, too, are written in the same spirit. They were not composed in his youth, in the heyday of his imagination, merely to gratify an idle curiosity in the reader, but in the evening of his life when his judgment was matured, and his experience at the full. Some of them were written to show the bitter fruits of a life of vice; and others to display in a vivid manner the importance of self-reliance, based on its proper foundation, a sincere and Christian trust in Providence, under all circumstances; with the inestimable value of a practical education, and a thorough acquaintance with the arts of life, and what too many persons are foolishly apt to despise as common things. That these were the paramount objects De Foe had in view is evident not only from a perusal of these valuable works, but from his own strongly asserted statements in his prefaces both to Moll Flanders and Robinson Crusoe. In the former, he says, "as the whole relation is usefully garbled of all the levity and looseness that was in it, so it is applied with the utmost care to virtuous and religious uses. None can, without being guilty of manifest injustice, cast any reproach upon it, or upon our design in publishing it. The advocates of the stage have in all ages made this the great argument, to persuade people that their plays are useful, and that they ought to be allowed in the most civilized, and in the most religious government; namely, that they are applied to virtuous purposes, and that, by the most lively representations, they fail not to recommend virtue and generous principles, and to discourage and expose all sorts of vice and corruption of manners; and were it true that they did so, and that they constantly adhered to that rule, as the test of their acting on the theatre, much might be said in their favour.
