The great ease of living that we now enjoy, the lofty intellectual development of our day, permit us to relax the severe discipline that poorer times and peoples, constrained to lead a harder life, had to impose upon themselves.  Although the habit may seem hard and barbarous, certainly almost all the great peoples of the past, and the majority of those contemporary who live outside our civilization, have conceived and practised matrimony not as a right of sentiment, but as a duty of reason.  To fulfil it, the young have turned to the sagacity of the aged, and these have endeavored to promote the success of marriage not merely to the satisfaction of a single passion, usually as brief as it is ardent, but according to a calculated equilibrium of qualities, tendencies, and material means.

The principles regulating Roman marriage may seem to us at variance with human nature, but they are the principles to which all peoples wishing to trust the establishment of the family not to passion as mobile as the sea, but to reason, have had recourse in times when the family was an organism far more essential than it is to-day, because it held within itself many functions, educational, industrial, and political, now performed by other institutions.  But reason itself is not perfect.  Like passion, it has its weakness, and marriage so conceived by Rome produced grave inconveniences, which one must know in order to understand the story, in many respects tragic, of the women of the Caesars.

The first difficulty was the early age at which marriages took place among the aristocracy.  The boys were almost always married at from eighteen to twenty; the girls, at from thirteen to fifteen.  This disadvantage is to be found in all society in which marriage is arranged by the parents, because it would be next to impossible to induce young people to yield to the will of their elders in an affair in which the passions are readily aroused if they were allowed to reach the age when the passions are strongest and the will has become independent Hardly out of childhood, the man and the woman are naturally more tractable.  On the other hand, it is easy to see how many dangers threatened such youthful marriages in a society where matrimony gave to the woman wide liberty, placing her in contact with other men, opening to her the doors of theaters and public resorts, leading her into the midst of all the temptations and illusions of life.

The other serious disadvantage was the facility of divorce.  For the very reason that matrimony was for the nobility a political act, the Romans were never willing to allow that it could be indissoluble; indeed, even when the woman was in no sense culpable, they reserved to the man the right of undoing it at any time he wished, solely because that particular marriage did not suit his political interests.  And the marriage could be dissolved by the most expeditious means, without formality—­by a mere letter!  Nor was that enough.  Fearing that love might outweigh reason and calculation in the young, the law granted to the father the right to give notice of divorce to the daughter-in-law, instead of leaving it to the son; so that the father was able to make and unmake the marriages of his sons, as he thought useful and fitting, without taking their will into account.
