by an informal demarcation of function. In the Victorian era, English family life increasingly became compartmentalised, the home a self-contained structure housing a nuclear family extended according to need and circumstance to include blood relations. The concept of "privacy" became a hallmark of the middle-class life. Evangelicals, utilitarians, and reform The central feature of Victorian-era politics is the search for reform and improvement, including both the individual personality and society. Three powerful forces were at work. First was the rapid rise of the middle class, in large part displacing the complete control long exercised by the aristocracy. Respectability was their code—a businessman had to be trusted and must avoid reckless gambling and heavy drinking. Second, the spiritual reform closely linked to evangelical Christianity, including both the Nonconformist sects, such as the Methodists, and especially the evangelical or Low Church element in the established Church of England, typified by Lord Shaftesbury (1801–1885). It imposed fresh moralistic values on society, such as Sabbath observance, responsibility, widespread charity, discipline in the home, and self-examination for the smallest faults and needs of improvement. Starting with the anti-slavery movement of the 1790s, the evangelical moralizers developed highly effective techniques of enhancing the moral sensibilities of all family members and reaching the public at large through intense, very well organized agitation and propaganda. They focused on exciting a personal revulsion against social evils and personal misbehaviour. Asa Briggs points out, "There were as many treatises on 'domestic economy' in mid-Victorian England as on political economy" The third effect came from the liberalism of philosophical utilitarians, led by intellectuals Jeremy Bentham (1748–1832), James Mill (1773–1836) and his son John Stuart Mill (1806–1873). They were not moralistic but scientific. Their movement, often called "Philosophic Radicalism," fashioned a formula for promoting the goal of "progress" using scientific rationality, and business-like efficiency, to identify, measure, and discover solutions to social problems. The formula was an inquiry, legislation, execution, inspection, and report. In public affairs, their leading exponent was Edwin Chadwick (1800–1890). Evangelicals and utilitarians shared a basic middle-class ethic of responsibility and formed a political alliance. The result was an irresistible force for reform. Social reforms focused on ending slavery, removing the slavery-like burdens on women and children, and reforming the police to prevent crime, rather than emphasizing the very harsh punishment of criminals. Even more important were political reforms, especially the lifting of disabilities on nonconformists and Roman Catholics,
