Abstract
The past two centuries have been an extraordinary era for criticism and reform of institutions and social practices. Unprecedented egalitarian and humanitarian movements have arisen to protest and improve the condition of victims of every variety of evil, personal and impersonal, natural and social. The beneficiaries of these movements belong to all manner of groups: racial, ethnic, and religious minorities, the poor, the insane, the orphaned, the handicapped, the homosexual, the young, the elderly, the female, the animal, the unborn, and so on. Many of these movements had few followers and fewer victories until deep into this century, but most had precursors in the last century, which challenged the moral legitimacy of accepted practices.
