Hi David
You have brought up a lot of questions regarding what I mean by certain things.
I have tried to summarize my argument again below concentrating on clarifying your questions.
I hope I have covered most of them and I am sure you will let me know what I have not covered.
Well, yes. My thinking as to why this is the case is similar to the reasons given by many non-western philosophy's as to the problem of consciousness, the "noisy" mind.
Starting out with the premise that consciousness is a reality and can therefore be be observed I have consciously been trying to refer to the most basic manifestation of the observation of consciousness using the definition , aware of ones thought .
How do I come to this definition?
Identifying first the most basic manifestation of an observation is an important principal of any scientific investigation.
In this case if we examined our own consciousness we could identify basic starting points for a scientific investigation.
As far as our own consciousness is concerned we can minimize perception (sensory input and all its related nerve functions to a minimum) by consciously removing that which would not be necessary from our minds and environment till the brink of becoming unconscious.
This is commonly known as "meditation", but I personally do not like this term as it has too much baggage.
Another useful exercise is to examine one's state of mind in the last moments before falling asleep and in the first moments of awakening.
It is important to note again I am only referring to perceptions of which we are aware.
What I have found by doing these things is that we can most easily reduce external sensory information.
Then if we want to reduce internal sensory information resulting from our body this involves more effort.
Of course having an illness or injury makes this part even more difficult if not impossible. So I will assume a healthy person.
My experience has been that immediately after balanced physical exercises (not too much not too little) in which one participates fully with delight one can get a feeling which many people would describe as "I feel great".
This really means they are not aware of there bodies being under the influence by gravity and any of the related aches and pains resulting therefrom.
They feel light, young and supple.
This is also an interesting observation as regards the consciousness of a child, but that is another story.
Yoga for instance is designed to get the body into this state by various well designed exercises and then whilst in this state to meditate by quietly stilling ones remaining thoughts using various techniques. Interestingly this stage is the most difficult if not almost impossible thing to do by far, eliminating all thoughts.
I believe the exercise of meditation of ultimately quieting the mind of thoughts can lead oneself to that point were I am fully aware right up to the point at which I pass from an conscious to an unconscious state.
Hence my basic definition of consciousness (being aware of ones thoughts).
Now you have routinely asked me what I mean by "thinking" and in the post I am addressing you also
you ask question
s that we are not aware of thinking when it occurs.
The question as to what I mean by thinking should be clearer now, in that even with conscious effort to reduce awareness as much as possible we are still left with thinking which does not want to "go away" as such until we are unconscious and we can no longer differentiate. Therefore thinking for me is that which makes us aware of being conscious, i.e. having a conscious mind which can tell the difference between itself and its thoughts.
As far as awareness of thinking whilst we think is concerned, it now transpires that my consciousness is dependent on the thoughts resulting from my thinking and my awareness of thinking is dependent on my consciousness. The question of memory is therefore related directly to consciousness. More consciousness more memory. More memory more consciousness.
Finally
The last and most important pose in any Yoga routine is Savasana (
http://en.wikipedia.org/wiki/Savasana) which often induces one to become unconscious.
All this is done in order to bring attention to what consciousness is.
What I would be interested in is a scientific investigation, and hence the questions about numbers of brain cells earlier in this thread, as to what activity is happening in the brain under these conditions and how much brain tissue is involved.
