Thought is a computation. OK. Experiential reality is a computation. OK.No. When you say "experiential reality" is a computation, you aresaying something ambiguous, where comp is far more precise. Because ifI can survive with a digital brain, then the experiential reality, thefirst person, subjective, experience is not a attachable to acomputation, but to an infinity of computations, and it obeys a logicdriven by the knowing arithmetical points of view, which makes itcloser to the non computable notion of "inner god" than to a 3-personcomputation. The first person cannot even describe (or name, in thelogician terms) itself.

`Yes! As Everett demonstrates, experiential reality is essentially a very`

`simple computation. It is the addition of each new observation to the`

`record of observations. The not so simple bit is the computation of each`

`new observation, though in the Everything concept it is relatively`

`simple, since it is simply all possible observations.`

I think I quoted this before, but this is the computation. void transtemporal_reality () { /* Initialisation */ Boolean new_observation = true; Observation observation = LIGHT; Functional_Identity observer = 1; World world_hologram = NO_OBSERVATIONS; Correlations_Record observables[]; Quantum_State ?; Elapsed_Time t = 0; int c = 0; while (observer != 0) {

`/* Process 1 -- Quantum time -- Change of quantum mechanical frame of`

`reference */`

if ( new_observation ) { world_hologram = world_hologram + observation; display (world_hologram); observer = observer + observation; observables[c++] = observation; ? = quantum_state_defined_by (observables) new_observation = false; } /* Process 2 -- Space-time time -- Change of inertial frame of reference */ else { t = t + PLANCK_TIME new_observation = compute_neural_state (?, t); if ( new_observation) observation = get_sensorium_contents(); break; } } }

`If variables ?, observation, and observables[], and function`

`get_sensorium_contents() were instantiated in suitably coherent memory`

`of a quantum computer, such a program would produce the subjective`

`realities of all possible functional identities of an observer, in the`

`form of Everett's branching tree of memory configurations.`

`It should be noted that objectively, in a no-collapse universe, ? is`

`properly a pointer, or reference, to a pre-existing quantum state, and`

`that the implementation of the statement`

new_observation = compute_neural_state (?, t);

`is simply reading a specific attribute of that quantum state, as from a`

`lookup table. This works very nicely given that each observable is a`

`correlation with a specific quantum state of the environment, the`

`correlations record being the simultaneity of all such correlations: a`

`set of commuting operators.`

Simple or not, this does not seem ambiguous. Andrew -- You received this message because you are subscribed to the Google Groups "Everything List" group.
