necessarily hostile to Christianity, as Huxley repeatedly emphasized. The literary figures were caught in something of a trap – their business was writing and their theology said there was nothing for certain to write. They instead concentrated on the argument that it was not necessary to believe in God to behave in moral fashion. The scientists, on the other hand, paid less attention to theology and more attention to the exciting issues raised by Charles Darwin in terms of evolution. The proof of God's existence that said he had to exist to have a marvellously complex world was no longer satisfactory when biology demonstrated that complexity could arise through evolution. Because of these developments in science, the emergence of higher criticism of the Bible, and the appeal of freethinkers, historians refer to a "Victorian Crisis of Faith" — a period of painful adjustment in family relationships and public morality resulting from shifting religious views. Marriage and family The centrality of the family was a dominant feature for all classes. Worriers repeatedly detected threats that had to be dealt with: working wives, overpaid youths, harsh factory conditions, bad housing, poor sanitation, excessive drinking, and religious decline. The licentiousness so characteristic of the upper class of the late 18th and early 19th centuries dissipated. The home became a refuge from the harsh world; middle-class wives sheltered their husbands from the tedium of domestic affairs. The number of children shrank, allowing much more attention to be paid to each child. Extended families were less common, as the nuclear family became both the ideal and the reality. In Great Britain, elsewhere in Europe, and in the United States, the notion that marriage should be based on romantic love and companionship rather than convenience, money, or other strategic considerations grew in popularity during the Victorian period. Cheaper paper and printing technology made it easier for humans to attract mates this way, hence the birth of the Valentine card. Status of women The emerging middle-class norm for women was separate spheres, whereby women avoid the public sphere – the domain of politics, paid work, commerce, and public speaking. Instead, they should dominate in the realm of domestic life, focused on the care of the family, the husband, the children, the household, religion, and moral behaviour. Religiosity was in the female sphere, and the Nonconformist churches offered new roles that women eagerly entered. They taught in Sunday
