In Punishment, Communication, and Community, R. A. Duff conceives of communication with persons being punished as “purposive communication,” rather than “instrumental technique,” and as involving “correction and persuasion,” rather than “moral education.”^ Such distinctions are not likely to be meaningful in the administrative practice of prison officials. Irrespective of how those distinctions are understood, such communication is much different from prisoners’ communication with family and friends. Communication with families and friends is commonly neither purposive nor instrumental.
