Why do we thus go back for principles that should always rest on the same base, and have the same weight to-day that they had a thousand years ago--and not a jot more? If parents discharge their duty they have a strong hold and sacred claim on the gratitude of their children; but few parents are willing to receive the respectful affection of their offspring on such terms. They demand blind obedience, because they do not merit a reasonable service: and to render these demands of weakness and ignorance more binding, a mysterious sanctity is spread round the most arbitrary principle; for what other name can be given to the blind duty of obeying vicious or weak beings, merely because they obeyed a powerful instinct? The simple definition of the reciprocal duty, which naturally subsists between parent and child, may be given in a few words: The parent who pays proper attention to helpless infancy has a right to require the same attention when the feebleness of age comes upon him. But to subjugate a rational being to the mere will of another, after he is of age to answer to society for his own conduct, is a most cruel and undue stretch of power; and perhaps as injurious to morality, as those religious systems which do not allow right and wrong to have any existence, but in the Divine will. I never knew a parent who had paid more than common attention to his children, disregarded (Dr. Johnson makes the same observation.); on the contrary, the early habit of relying almost implicitly on the opinion of a respected parent is not easily shaken, even when matured reason convinces the child that his father is not the wisest man in the world. This weakness, for a weakness it is, though the epithet AMIABLE may be tacked to it, a reasonable man must steel himself against; for the absurd duty, too often inculcated, of obeying a parent only on account of his being a parent, shackles the mind, and prepares it for a slavish submission to any power but reason. I distinguish between the natural and accidental duty due to parents. The parent who sedulously endeavours to form the heart and enlarge the understanding of his child, has given that dignity to the discharge of a duty, common to the whole animal world, that only reason can give. This is the parental affection of humanity, and leaves instinctive natural affection far behind. Such a parent acquires all the rights of the most sacred friendship, and his advice, even when his child is advanced in life, demands serious consideration. With respect to marriage, though after one and twenty a parent seems to have no right to withhold his consent on any account; yet twenty years of solicitude call for a return, and the son ought, at least, to promise not to marry for two or three years, should the object of his choice not entirely meet with the approbation of his first friend.
