This paper considers insoluble difficulties for the supposition that intentions, “acts of will”, and reasons for acting, construed as mental events, could be the special ingredient that would render bodily movements into voluntary or intentional actions. Yet, the distinction between mere bodily movements and actions is often made by introducing intentions, acts of will, and reasons for acting. How is this to be reconciled? Criticising the tendency to view the “thick descriptions” of everyday discourse through a metaphysical scheme that relies (...) on the topic-neutral lens of an extensional calculus, the paper proposes a different solution that rejects the original supposition that a mental cause of some sort is required to accommodate the differences.
