There is little doubt among scientists and the general public that homelessness, mental illness, and addiction are inter-related. In Of Others Inside, Darin Weinberg examines how these inter-relations have taken form in the United States. He links the establishment of these connections to the movement of mental health and addiction treatment from redemptive processes to punitive ones and back again, and explores the connection between social welfare, rehabilitation, and the criminal justice system.

Seeking to offer a new sociological understanding of the relationship between social exclusion and mental disability, Of Others Inside considers the general social conditions of homelessness, poverty, and social marginality in the U.S. Weinberg also explores questions about American perceptions of these conditions, and examines in great detail the social reality of mental disability and drug addiction without reducing people's suffering to simple notions of biological fate or social disorder.
