But if this is the duty of any, it is the duty of all; and we are to inquire what would be the result, if all conscientious persons gave up the use of all superfluities. Suppose that two millions of the people of the United States were conscientious persons, and relinquished the use of every thing not absolutely necessary to life and health. Besides reducing the education of the people in all the higher walks of intellectual, social, and even moral development, to very narrow limits, it would instantly throw out of employment one half of the whole community. The writers, book-makers, manufacturers, mechanics, merchants agriculturists, and all the agencies they employ, would be beggared, and one half of those not reduced to poverty would be obliged to spend all their extra means in-simply supplying necessaries to the other half. The use of superfluities, therefore, to a certain extent, is as indispensable to promote industry, virtue, and religion, as any direct giving of money or time; and it is owing entirely to a want of reflection and of comprehensive views, that any men ever make so great a mistake as is here exhibited. Instead, then, of urging a rule of duty which is at once irrational and impracticable, there is another course, which commends itself to the understandings of all. For whatever may be the practice of intelligent men, they universally concede the principle, that our physical gratifications should always be made subordinate to social, intellectual, and moral advantages. And all that is required for the advancement of our whole race to the most perfect state of society is, simply, that men should act in agreement with this principle. And if only a very small portion of the most intelligent of our race should act according to this rule, under the control of Christian benevolence, the immense supplies furnished for the general good would be far beyond what any would imagine who had never made any calculations on the subject. In this nation alone, suppose the one million and more of professed followers of Christ should give a larger portion of their means for the social, intellectual, and moral wants of mankind, than for the superfluities that minister to their own taste, convenience, and appetite; it would be enough to furnish all the schools, colleges, Bibles, ministers, and missionaries, that the whole world could demand; or, at least, it would be far more than properly qualified agents to administer it could employ. But it may be objected that, though this view in the abstract looks plausible and rational, not one in a thousand can practically adopt it. How few keep any account, at all, of their current expenses! How impossible it is to determine, exactly, what are necessaries and what are superfluities! And in regard to women, how few have the control of an income, so as not to be bound by the wishes of a parent or a husband!
