The monogamic relation having been defined in the preceding paragraphs I recur to some of its obligations. I have spoken of the infidelity of woman as of a higher degree of criminality than that of man, and have shown the basis of justice on which this general sentiment rests. But it must not be forgotten that while he who hires a murderer, and he who receives stolen goods does not commit the actual crime, he is highly culpable, and shares in the condemnation which should follow it. In the case of the marital infidelity of the woman, he may be the greater criminal of the two, as the instigator to a deed which would not have been otherwise even suggested. In any case his folly is extraordinary, as he takes his life in his hands, and risks that of his partner; for men are wont to preserve their family rights by summary process. It would be incredible that such risks should be taken were it not that history and contemporary literature offer many examples. The few cases where palliating circumstances could be claimed would chiefly occur in countries where divorce laws do not exist. The advantages to woman, arising from the monogamic relation, are then, support and protection, and undivided affection if she deserve it, together with the satisfaction of the conjugal and maternal instincts. In order to secure these advantages she must pursue a course towards her husband in some degree comparable to that by which her husband secures the confidence and esteem of his fellow man. Faithfulness in adhering to contracts, and personal complaisance cover much of the ground. As regards the man, he must see to it, that he does nothing that tends to the disintegration of the family relations of other men. The ill disguised laudation of the infidelity of wives which is so prominent in French literature, is a mark of a low civilisation, and it rightly excites the disgust of all men who have any respect for their own rights. It looks as though certain French literature had been written by boys. Men who are responsible for such invasion of the rights of others, cannot expect better treatment themselves, and they must not be surprised if they are repaid in their own coin. While the preservation of the rights of the marriage contract lies primarily with woman, for natural reasons; man is held by his fellow man to a strict accountability, and he attempts any invasion of them at his personal peril.
