Although law is in a sense an outline of life, it would be very misleading to fill up the content of Roman private life by analogy with this harsh outline. Like most of the theory of Roman law it had little correspondence with the facts; and this non-correspondence of fact and theory is the source of the strength and the beauty of Roman family life. If legal obligations do not exist between husband and wife, father and child, their place, in a civilised community, must be taken by moral obligations; and the very absence of legal sanctions will make these moral bonds peculiarly strong. It was so with the Roman family. It was an isolated, self-existent unit. The members clung closely to one another and to their head. The power of the father—the source of the unity of the household—fostered the devotion to the hearth, the love of home, which is such a distinctive attribute of the Roman. It created the belief that the members of the household, owing allegiance to a common chief, should act loyally by one another in all the relations of life, and loyalty to a living head begat loyalty to his predecessors; traditions of this union as persisting under the rule of a long line of deceased ancestors, account for the hereditary policy of Roman houses—the championship of principles advocated for centuries by such clans as the Valerii, the Porcii, and the Claudii. The moral influence on the _pater_ was also great. He defends, not his own selfish rights, but the rights of a corporation dependent on him; “self-help” is the essence of the principles of early Roman law. In private matters the authority of the state is weak, that of the individual strong. The rule of the Roman father was the benevolent despotism that embraces many within the sphere of its despotic interests, that forces others to observe its rights because its interests are _not_ personal, that produces a deep sense of moral and religious responsibility towards the weak, a stern unyielding attitude towards the man who would infringe upon their rights. The only “individual” known to Roman law is the _paterfamilias_, but his was a glorified individuality, which, through its rule over the family, gathered strength to rule the world.
