To go back to the beginning—a primary cause of unhappy marriage is a _defective moral and physical education_. In our country intellectual education is on a par with that of other enlightened nations of the earth—not so moral and physical education. Prudence, fortitude, truth, reverence, and fidelity, are not inculcated here as they should be. Industry, activity, and enterprise are our national good points of character, and these are impressed upon children by example, rather than by admonition; and our virtues, generosity, hospitality, courage, and patriotism, are the virtues of constitution and of circumstance, rather than of education. We fail to impress the duty of PRUDENCE upon our children, and hence rash and culpable mercantile speculation, ending in insolvency—and hence hasty, inconsiderate marriages, ending in bankruptcy of heart, home, and happiness. We fail to impress the duty of FIDELITY upon our children, and hence irregularity and unfaithfulness in business, embezzlement of funds, &c., and hence broken marriage faith and deserted families. We fail to inculcate the duty of FORTITUDE, and hence, when obligations, professional or matrimonial, become painful, they are too often abandoned. But it is PHYSICAL EDUCATION, in its relation to the happiness of married life, that I wish to discuss. We are still more thoughtlessly neglectful, and I was about to say, _fatally_ neglectful of physical, than of moral education. _Fatally_, because no moral education can be completely successful, unless assisted and supported by a good physical training. An instance—preach patience for ever, yet a dyspeptic _will_ be ill-tempered. Another—preach industry for ever, yet the weak and languid _will_ be lazy and idle. A third—inculcate the necessity of courage, presence of mind, by eloquent precept, and by the example of all the heroes and heroines of history, yet the nervous _will_ start if a door claps. One might go on _ad infinitum_.
