Re: Conventional QTI = False

Hi Saibal,

I don't know if there is an accepted formulation for QTI and the
conservation of memory, however, the only constraint that seems logical
to me is that the consciousness extensions should be logically
consistent, because logical consistenty is a prerequisite for
consciousness.

I can imagine certain branches in which memory is totally lost, (the
null case so to speak - because there is really no consciousness
continuation) and other branches where memory is totally conserved, yet
other cases where memory is transformed to reflect a different
past....All these will come true as long as there is a logical
explanation for them to happen. You must keep in mind as Jacques
mentionned, that memory is not necessary identical with the past. It
only represents the present brain state which reflects in a consistent
fashion more or less precisely what the past was.

In some branches you will experience increasing old age without limit...
all ou need is the logical explanation.
For example upon dying as a human, you may wake up as a billion year old
ten arm octopus living in a 30 dimensional space realizing that you were
just dreaming in 3-Land. The number of explanations seems limitless.

In this list, we are what we are, our age probably ranging from 20 to 80
because of our surrounding, because of anthropic reasons. Had we been a
billion year old group (with the corresponding historical-anthropic
reasons for being 1 billion year old), God knows what we would be
talking and worrying about, but we would certainly not be debating this
(F)allacious (I)nsane (N)onsense. :-)
