Christopher (Kit) Lasch was a well-known American historian, moralist, and social critic.

Mentored by William Leuchtenburg at Columbia University, Lasch was a professor at the University of Rochester. Lasch sought to use history as a tool to awaken American society to the pervasiveness with which major institutions, public and private, were eroding the competence and independence of families and communities. He strove to create a historically informed social criticism that could teach Americans how to deal with rampant consumerism, proletarianization, and what he famously labeled the "culture of narcissism." His books, including The New Radicalism in America (1965), Haven in a Heartless World (1977), The Culture of Narcissism (1979), and The True and Only Heaven (1991), were widely discussed and reviewed. The Culture of Narcissism became a surprise best-seller.

Lasch was always a critic of liberalism, and a historian of liberalism's discontents, but over time his political perspective evolved dramatically. In the 1960s, he was a neo-Marxist and acerbic critic of Cold War liberalism. During the 1970s, he began to become a far more iconoclastic figure, fusing cultural conservatism with a Marxian critique of capitalism, and drawing on Freud-influenced critical theory to diagnose the ongoing deterioration that he perceived in American culture and politics. His writings during this period led him to be denounced by feminists and hailed by conservatives for his apparent defense of the traditional family. He eventually concluded that an often unspoken but pervasive faith in "Progress" tended to make Americans resistant to many of his arguments. In his last major works he explored this theme in depth, suggesting that Americans had much to learn from the suppressed and misunderstood Populist and artisan movements of the nineteenth and early twentieth centuries.

His basic thesis about the family, which he first expressed in 1965 and explored for the rest of his career, was:

"When government was centralized and politics became national in scope, as they had to be to cope with the energies let loose by industrialism, and when public life became faceless and anonymous and society an amorphous democratic mass, the old system of paternalism (in the home and out of it) collapsed, even when its semblance survived intact. The patriarch, though he might still preside in splendor at the head of his board, had come to resemble an emissary from a government which had been silently overthrown. The mere theoretical recognition of his authority by his family could not alter the fact that the government which was the source of all his ambassadorial powers had ceased to exist."
