STEPHEN GUEST writes mostly on legal and political philosophy, particularly concerning the question of justification in legal reasoning and the relationship between justice, interpretation and laws. His well-known book Ronald Dworkin appeared in its third edition in 2012. Amongst other work, he has published in Public Law on constitutional problems of legal revolution, the Law Quarterly Review on hearsay evidence, the Journal of Medical Ethics on the rights of the subjects of medical research, Acta Juridica on the role of equality within legal reasoning, and Revue Internationale de Philosophie on the idea that law is a form of justice (to which Dworkin published a reply). He has recently published essays on the legality of the Pitcairn child abuse prosecutions both for Oxford U.P. and the New Zealand Law Journal and his father's experience as a POW lecturing on the University of London External degree programme in Stalag IVB in Muhlberg, Germany, and Campo 52 in Chiavari, Italy. In 2009 he gave a public lecture at UCL entitled 'The Right to Obscene Thoughts' for which he was nominated as Academic of the Year by the Erotic Awards.
