with this and replaces my vague phrase “certain complex ways” by a precise definition: the information processing needs to be integrated, that is, Φ needs to be large. Giulio’s argument for this is as powerful as it is simple: the conscious system needs to be integrated into a unified whole, because if it instead consisted of two independent parts, then they’d feel like two separate conscious entities rather than one. In other words, if a conscious part of a brain or computer can’t communicate with the rest, then the rest can’t be part of its subjective experience.
