A new class of visuomotor neuron has been recently discovered in the monkey’s premotor cortex: mirror neurons. These neurons respond both when a particular action is performed by the recorded monkey and when the same action, performed by another individual, is observed. Mirror neurons appear to form a cortical system matching observation and execution of goal-related motor actions. Experimental evidence suggests that a similar matching system also exists in humans. What might be the functional role of this matching system? One (...) possible function is to enable an organism to detect certain mental states of observed conspecifics. This function might be part of, or a precursor to, a more general mind-reading ability. Two different accounts of mind-reading have been suggested. According to “theory theory‘, mental states are represented as inferred posits of a naive theory. According to “simulation theory‘, other people’s mental states are represented by adopting their perspective: by tracking or matching their states with resonant states of one’s own. The activity of mirror neurons, and the fact that observers undergo motor facilitation in the same muscular groups as those utilized by target agents, are findings that accord well with simulation theory but would not be predicted by theory theory.

The papers in this issue of Public Health Ethics arise from a workshop on the role of political philosophy in public health ethics, held at Manchester Metropolitan University in September 2008.1 Part of the reason for exploring the role of political philosophy in relation to public health (and public health ethics) is the thought that the political is ineliminably social: it is about how we live together. Exactly what public health is and what it ought to be is contested, but (...) it surely involves the two senses of public in the sense of the object of attention (i.e., societal or population health) and also the mode of delivery (i.e., collective or participatory action) (Verweij and Dawson, 2007). Political philosophy is concerned with actions in the public sphere related to both these elements. (shrink)

Susan Hurley has argued against a well known argument for freedom of speech, the argument from autonomy, on the basis of two hypotheses about violence in the media and aggressive behaviour. The first hypothesis says that exposure to media violence causes aggressive behaviour; the second, that humans have an innate tendency to copy behaviour in ways that bypass conscious deliberation. I argue, first, that Hurley is not successful in setting aside the argument from autonomy. Second, I show that the empirical (...) data are irrelevant to statutory regulation of media violence. They do not yield a sufficiently strong correlation between exposure to media violence and non-autonomously copied criminal violence, and they do not yield a way ex ante to individuate the viewers who will be affected by media violence.
