As a "Youthful Offender" (No permanent Criminal Record), I had an index card on the wall of my prison cell, with a quote from someone whose name I do not now recall:
"To Punish a Man, you must injure him; To Reform a Man, you must improve him; and Men are not improved by Injuries."
If your favorite Librarian has access to Bartlett's Familiar Quotations...I just asked my favorite Librarian, who "googled" it, and is e-mailing it to me. The actual Quote is from George Bernard Shaw, but it appears in a Book about Philosophical Perspectives on Punishment edited by Gertrude ______. He's e-mailing me with particulars including the link. I'll try to get back to you, as the Library (and this public access computer terminal) is about to close.
