How should we respond to the inhumanity that suffused the 20th Century and continues in the present one? Has there been an adequate treatment of this issue by the political left? Questions such as these are treated in this, the first scholarly book to combine academic and blogging approaches to some of the major political issues of the day. It does this by focusing on the work of Norman Geras - Marxist, political philosopher and blogger - and developing the central themes of his work such as crimes against humanity, the Holocaust, Marxism, and the means/ends problem in politics. It contains contributions by famous political philosophers such as Michael Walzer, Hillel Steiner and David McLennan, and bloggers and journalists such as David Aaronovitch, Nick Cohen and Ophelia Benson. The book contains a unique response by Geras in which he draws together the various themes it covers. It will be of interest to all who are concerned with these pressing political issues of our times. The book will be particularly relevant for those with an academic or general interest in politics, philosophy, sociology, genocide studies, applied ethics, international relations, and law. It will also be of interest to bloggers and all those who regard the new technology as having significant implications for public debate on these issues.
