 The implicit argument here is that there is no genuine representation if there is no awareness of the representation. Whatever a dog qua machine is acting on when running to his master, it is not an internal representation of his master that the dog acts on with purpose. The “corporeal knowledge” would be nothing but connections or impressions of one body on another—without an awareness of these impressions and what they represent, they won’t serve the purposes of knowledge, sensation, action, or volition.
