Yes sorry this is my doing, tupper doesn't really care.

The reason I brought up quorum decision-making is because this is what hypothetically happens with all decisions 'we' make and what 'we' fundamentally are. Just a set of routines of unconscious processes that form what we perceive as our personality. The brain loves trodden paths and coherence with previous experiences stored in autobiographical memory. But there is not one ‘self’. It is highly fragmented, fluid, often contradictory and thus as you said in the other thread we can attribute certain routines to certain characters which in the end are no more or less real than 'us'. Likewise it is possible to merge and split such personalities or have the 'parts' simultaneously active with the 'whole'. Because in reality it's all just the sum of unconscious reactions to stimuli which have reached a certain threshold and thus manifested as 'conscious' actions. Such neuronal quorum decisions are astonishingly effective, fast and require zero intelligence. Even bacteria can do it as a collective.

Think of an anthill. The ants erratically move in all directions, some make nonsense like dismantling what has just been built, others just laze around although help would be desperately needed. But this is irrelevant noise. The emergent phenomenon of the insect state still has enormous powers way beyond the individual ant. Yet it has no leader and no personality telling it what to do. It just happens to create a net effect that's beneficial for survival and reproduction and this benefit is selected for. The brain is no different. Sounds unromantically materialistic but I am pretty certain that's all there is.
