reading this post caused me to read your expanding consciousness page..
first I must ask, why should we expand our consciousness?
you say "normal" consciousness is too mundane and limiting, but it seems to work quite well for many people... at the present time our way of life seems to require this kind of consciousness.. I'll grant that (if) in 50 years or so when we can be uploaded into computers, consciousness tinkering will become easy and may become an acceptable way of life for many people, but for now I think "normal" consciousness suits us well enough
you speak of time dilation, but I wonder if it really occurs, or is just an artifact of the altered state.. I know that time estimation, or the subjective pass of time changes (similar to how as a child time seemed much slower than it does now, at least for me) but I wonder if you can actually fit in more complete thoughts.. how would you even measure that?
next, why is being able to perceive a sense of vastness good? aside from that, I think the feeling is an artificial sense of vastness.. I would wager you can no better hold a galaxy in mind while altered than you can while at baseline
in minsky's the society of mind, he says that infants have no distinction between body and environment and that it is learned over time.. just as a note
but here too I wonder what's the point of this? why should this be a goal? if you would agree that the mind only has control over things it is physically connected to (by neurons), then having a greater sense of body is no more than an illusion
have you tried the experiment by which you can alter your perception of your body? the experiment is approximately as follows, as related to me by a friend a couple years ago (so I don't remember much)..
sit at a table and close your eyes (I forget if the eye closing is necessary, but to be safe...) and have a friend sit next to you
the friend is to take one of your hands with a finger extended and tap it on the table in time with vim tapping your nose with vis own finger
alas I forget how long this must be done, but eventually you'll feel the taps on the table as if it is your nose
I did a similar experiment while on mushrooms once, but with a chair and after a while I thought to myself "my chair is getting sore"
I'd like to try it drugfree sometime as drugs are not at all necessary for the experiment and probably clouded the feeling some
the ego-death section is too new-agey for me to reply to.. I don't believe that there is a "Self" outside of the mind's conception of itself
I must also question the goal of sensing a ubiquitous "presence".. simply because a part of your brain that is being affected by psychadelics makes you fell that a presence is there does not at all make it a part of the universe, waiting to be discovered
I'd like proof of your higher-dimensional spatial thought statement if you literally mean, for instance, imagining patterns in higher dimensional spaces
I've experienced discovering patterns and connections that I hadn't noticed before, but my judgement of them at the time was that they were noticed by ignoring parts of one or both of the objects being compared and that the connections in fact weren't there, or if so were really trivial or meaningless
your goal of ecstasy reminds me of the hedonistic imperative (
www.hedweb.com), a site you may want to look at if you're interested.. they take the idea quite a bit farther than sticking an electrode into your medial forebrain bundle (which really sounds like fun to me actually:))
finally, I don't understand multi-model integration I think.. aren't the modalities already integrated? isn't that what binding is? or are you talking more about synesthesia? (I can never spell that right.. I imagine that's close)
