The sacredness of the family tie is the condition both of the physical soundness and the moral vigor of nations. The family is the miniature commonwealth, upon whose integrity the safety of the larger commonwealth depends. It is the seedplot of all morality. In the child's intercourse with its parents the sentiment of reverence is instilled--the essence of all piety, all idealism; also the habit of obedience to rightful authority, which forms so invaluable a feature in the character of the loyal citizen. In the companionship of brothers deference to the rights of equals is practically inculcated, without which no community could exist. The relations between brother and sister give birth to the sentiment of chivalry,--regard for the rights of the weaker,--and this forms the basis of magnanimity, and every generous and tender quality that graces humanity. Reverence for superiors, respect for equals, regard for inferiors,--these form the supreme trinity of the virtues. Whatever is great and good in the institutions and usages of mankind is an application of sentiments that have drawn their first nourishment from the soil of the family. The family is the school of duties. But it has this distinguishing excellency, that among those who are linked together by the strong ties of affection duty is founded on love. On this account it becomes typical of the perfect morality in all the relations of life, and we express the noblest longings of the human heart when we speak of a time to come in which all mankind will be united "as one family." Now the preeminence of the Jews in point of domestic purity will hardly be disputed. "In this respect they stand out like a bold promontory in the history of the past, singular and unapproached," said the philosopher Trendelenburg.* According to the provisions of the Mosaic Code, the crime of adultery is punished with death. The most minute directions are given touching the dress of the priests and the common people, in order to check the pruriency of fancy. The scale of forbidden marriages is widely extended with the same end in view. * Vide the essay on the Origin of Monotheism in Jahrbuch des Vereins fur Wissenschaftliche Padagogik, Vol IX. 1877, by the author of this article.
