The point has been to suggest to the reader the potential delicacy, intricacy, and self-involvedness of a system that responds to external stimuli and to features at various levels of its own internal configuration. It is well-nigh impossible to disentangle such a system's response to the outside world from its own self-involved response, for the tiniest external perturbation will trigger a myriad tiny interconnected events, and a cascade will ensue. If you think of this as the system's 'perception' of input, then clearly its own state is also 'perceived' in a similar way. Self-perception cannot be disentangled from perception.
