The rationalist theory that there is a "transformation into" physical acts of some purely mental faculty of "Will" or "Volition" is therefore a misconception because it mistakenly assumes that a mental act could be and is distinct from a physical act, or even that a mental "world" could be and is distinct from the physical world. This theory of the separability of mind and body is described by Ryle as "the dogma of the ghost in the machine." He explains that the workings of the mind as it governs the body are neither an independent nor a distinct mechanism, that there is no entity called "Mind" inside a mechanical apparatus called "the body", but that the workings of the mind may be better conceptualized as the actions of the body.
