Let us now ask ourselves what we should call “speaking
121.
involuntarily”.
First note that when normally you speak, voluntarily, you could hardly
describe what happened by saying that by an act of volition you move your
mouth, tongue, larynx, etc. as a means to producing
certain sounds.
Whatever happens in your mouth, larynx, etc. and
whatever sensations you have in these parts while speaking would almost
seem secondary phenomena accompanying the production of sounds, and
volition, one wishes to say, operates on the sounds themselves without
intermediary mechanism.
This shews how loose our idea of this agent
“volition” is.
