That a craving for such happiness should have become intense in a man like Zola, with all the emotional tendencies of his temperament, was natural, perhaps fatal. It was one of the sufferings that made him seek a refuge in steady, all-absorbing work, and for years, by immersing himself in his task, he contrived to dull his pain and silence all the suggestions of a rebellious nature. Goncourt, one day after returning from a visit to Médan, jotted down in his diary some remarks about the gloom, the emptiness of that spacious abode. There were plenty of dogs, but there were no children, and children were necessary to such a home. It is evident that Goncourt with his keen penetration had divined the secret grief of its master and mistress. But years rolled on, and hopes first fondly cherished, then clung to with despairing tenacity, remained unfulfilled. The moralist will say undoubtedly that resignation was the one right course, but human nature seldom resigns itself willingly to anything, and certainly Zola's nature was not one to do so. As he approached his fiftieth year it began to assert itself, as Goncourt shows us in another passage of his "Journal"; and then, after long years of battling, however strong the spirit might still be, the flesh finally triumphed over it. It is unnecessary to review what the Bible and Buckstone, Taylor and Kent, Montesquieu and Potier have to say respecting the violation of the marriage vow, and the distinctions which may be drawn between the action of husband and of wife. Nor need there be any defence on the lines of the _théorie des deux morales_ as interpreted by Nisard. One may allow that there is strictly only one moral law for both sexes and for all stations in life, royal as well as plebeian. At the same time one is entitled to indicate whatever extenuating circumstances may exist. One may think of the position of Thomas and Jane Carlyle, as enunciated by the supporters of the former, and then picture a very different sequel, for in Zola's case a time came when he was carried away from the path of strict duty, and in the result a child was born to him, a daughter called Denise. Later came the birth of a son, called Jacques. An echo of what happened--the tempestuous passion of a man of ripe years for a young woman--resounded through the pages of "Le Docteur Pascal," while "Fécondité," published much later, revealed many of the sufferings, much of the yearning, that had led to this crisis in Zola's life.
