Three general purpose collectively run philosophy blogs that have appeared since I compiled my original list, which mix news, commentary and academic debate with substantial philosophical discussion in various areas: The Daily Nous, Feminist Philosophers, A Philosopher's Take. Other additions are individual philosophy blogs dedicated to substantial philosophical debate in selected topical areas. Two of these have become well established and highly regarded since the last update, Philosophical Disquisitions and The Splintered Mind.
But I would like to push a little bit extra for a very recently started blog by my dynamic colleague and good friend Richard Ashcroft, professor of bioethics at the School of law of the Queen Mary University of London: Utopian Biofutures. One of the most broadly conceiving and farsighted of philosophical bioethicists I know (being a scholar law and social science besides philosophy, applied ethics and political theory), this blog is dedicated to his latest project, where he sets out to combine his diverse scholarship with his astute knowledge and affinity for futuristic and SF fiction in an analysis that is to address what technological utopias for humanity and human societies we, where we stand now, have reason to consider and what we should think and do about them.
