Adam Kolber's The Subjective Experience of Punishment in the January 2009 Columbia Law Review has received a good deal of attention, including two new pieces (just up today) on the Columbia Law Review's Sidebar:
Retributivists Need Not and Should Not Endorse the Subjectivist Account of Punishment by Kenneth Simons
Evaluating the Consequences of Calibrated Sentencing: A Response to Professor Kolber by Miriam H. Baer
And coincidentally, Kolber is talking today at Illinois about his new and related paper, The Comparative Nature of Punishment.
