Despite the impressive body of evidence supporting the existence of a mirror neuron (MN) system for action, the original claim regarding its crucial role in action understanding remains controversial. Emma Borg has recently launched a sharp attack on this claim, with the aim of demonstrating that neither the original version nor the subsequent revisions of the MN hypothesis tell us very much about how intentional attribution actually works. In this article I take up the challenge she issues in the title of her paper (If Mirror Neurons are the Answer, What was the Question?) and argue that what MNs offer is not as Borg claims 'an extremely limited' picture of action understanding but rather an enriched picture that brings to light aspects of social cognition hitherto ignored in the mind-reading literature, showing how intentional motor components of action can shape social cognition prior to and apart from any forms of deliberate mentalizing.

Are there distinct roles for intention and motor representation in explaining the purposiveness of action? Standard accounts of action assign a role to intention but are silent on motor representation. The temptation is to suppose that nothing need be said here because motor representation is either only an enabling condition for purposive action or else merely a variety of intention. This paper provides reasons for resisting that temptation. Some motor representations, like intentions, coordinate actions in virtue of representing outcomes; but, unlike intentions, motor representations cannot feature as premises or conclusions in practical reasoning. This implies that motor representation has a distinctive role in explaining the purposiveness of action. It also gives rise to a problem: were the roles of intention and motor representation entirely independent, this would impair effective action. It is therefore necessary to explain how intentions interlock with motor representations. The solution, we argue, is to recognise that the contents of intentions can be partially determined by the contents of motor representations. Understanding this content-determining relation enables better understanding how intentions relate to actions
