We first correct some errors in Lepore and Stone’s discussion of speaker meaning and its relation to linguistic meaning. With a proper understanding of those notions and their relation, we may then motivate a liberalization of speaker meaning that includes overtly showing one’s psychological state. I then distinguish this notion from that of expression, which, although communicative, is less cognitively demanding than speaker meaning since it need not be overt. This perspective in turn enables us to address Lepore and Stone’s broadly Davidsonian view of figurative language, which rightly emphasizes the role of imagination and perspective-taking associated with such language, but mistakenly suggests it is sui generis relative to other types of pragmatic process, and beyond the realm of communication. Figurative utterances may influence conversational common ground, and may be assessed for their aptness; they also have a characteristically expressive role that a Davidsonian view lacks the resources to explain.

Abstract Background Research suggests that unconscious activity in the supplementary motor area (SMA) precedes not only certain simple motor actions but also the point at which we become aware of our intention to perform such actions. The extent to which these findings have implications for our understanding of the concepts of free will and personal responsibility has been subject of intense debate during the latest four decades. Methods This research is discussed in relation to effects of neurosurgical removal of the SMA in a narrative review. Results Removal of the SMA typically causes a transient inability to perform non-stimulus-driven, voluntary actions. This condition, known as the SMA syndrome, does not appear to be associated with a loss of sense of volition but with a profound disruption of executive function/cognitive control. Conclusions The role of the SMA may be to serve as a gateway between the corticospinal tract and systems for executive function. Such systems are typically seen as tools for conscious decisions. What is known about effects of SMA resections would thus seem to suggest a view that is compatible with concepts of personal responsibility. However, the philosophical question whether free will exists cannot be definitely resolved on the basis of these observations.
