The early Christian community developed a methodology for correcting human error that featured the unprecedented belief that a period of time spent in a given penitential locale, with the aid and encouragement of the community, was sufficient in and of itself to heal the alienation and self-loathing caused by sin and to lead an individual to full reincorporation into the community. The "correctional" practice was based upon the conviction that cooperative sociability--or conversion--is possible, regardless of the specific offense, without any need to inflict suffering, or to use the act of punishment as a warning to potential offenders, or to undertake programmatic interventions into the lives of the incarcerated for the purpose of rehabilitating them.

Andrew Skotnicki contends that the modern practice of criminal detention is a protracted exercise in needless violence predicated upon two foundational errors. The first is an inability to see the imprisoned as human beings fully capable of responding to an affirmative accompaniment rather than maltreatment and invasive forms of therapy. The second is a pervasive dualism that constructs a barrier between detainees and those empowered to supervise, rehabilitate, and punish them. In this book, Skotnicki argues that the criminal justice system can only be rehabilitated by eliminating punishment and policies based upon deterrence, rehabilitation, and the incapacitation of the urban poor and returning to the original justification for the practice of confinement: conversion.
