""A Popular Essay On Subjects Of Penal Law, And On Uninterrupted Solitary Confinement At Labor"" is a book written by Francis Lieber in 1838. The book discusses various topics related to penal law, including the history and philosophy of punishment, the principles of criminal justice, and the role of prisons in society. One of the main focuses of the book is on the practice of uninterrupted solitary confinement at labor, which Lieber argues is a more effective and humane form of punishment than traditional methods such as physical torture or the death penalty. Lieber's arguments are based on his own experiences as a political prisoner in Germany, as well as his extensive research on the subject. The book is written in a clear and accessible style, making it suitable for a general audience interested in the history and theory of criminal justice.As Contradistinguished To Solitary Confinement At Night And Joint Labor B Y Day, In A Letter To John Bacon.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
