CONCEPT
Phenomenal Self-Model
Metzinger’s name for the brain’s transparent, integrated representation of the organism as a whole—the process that generates the felt sense of being a someone, and the component whose presence or absence in artificial systems is the hinge on which the possibility of machine suffering turns.
The phenomenal self-model—PSM—is the brain’s ongoing simulation of itself: a representation that integrates bodily sensations, emotions, perceptions, and acts of will into a unified sense of being one entity, here, now, with this body and these feelings.
Thomas Metzinger’s central claim is that this is not a description of a self that exists independently, but rather what the self is—a representational achievement that the brain performs and that produces the phenomenology of being someone as its result. The model is transparent in the technical sense: the system running it cannot see it as a model. It fuses with the content, so that distinguishing the self-model from the self feels like a philosophical abstraction rather than a practical operation. What makes this technically and ethically decisive is that the PSM is one of four necessary conditions
