Source: (2008) In, John F. Wozniak, et. al, editors. Transformative Justice: Critical and Peacemaking Themes Influenced by Richard Quinney. Lanham, MD: Lexington Books. pp. 33-42.The relationship of Richard Quinney's critical criminology to Marxism is explored in this article. The originality of his version of critical criminology is discussed, from its origins in social constructionism, to his engagement with Marxism in the 1970s, to the importance in his later work of issues such as existentialism, Eastern thought, and Erich Fromm's socialist humanism. It is argued that Quinney's writings, despite several shifts of perspective, nonetheless exhibit some basic continuities and that an engagement with various forms of unorthodox, humanistic Marxism is one of these.
