Introdotte nell'analisi sistemica degli stati di coscienza le tre componenti di sistema: consapevolezza - energia e strutture, Charles T. Tart ne descrive le caratteristiche e le interazioni:
Awareness and Energy
We begin with a concept of some kind of basic awareness — an ability to know or sense or cognize or recognize that something is happening. This is a basic theoretical and experiential given. We do not know scientifically what its ultimate nature is, but it is where we start from. I call this concept attention/awareness, to relate it to another basic given, which is that we have some ability to direct this awareness from one thing to another.
This basic attention/awareness is something we can both conceptualize and (to some extent) experience as distinct from the particular content of awareness at any time. I am aware of a plant beside me at this moment of writing and if I turn my head I am aware of a chair. The function of basic awareness remains in spite of various changes in its content.
A second basic theoretical and experiential given is the existence, at times, of an awareness of being aware, self-awareness. The degree of self-awareness varies from moment to moment. At one extreme, I can be very aware that at this moment I am aware that I am looking at the plant beside me. At the other extreme, I may be totally involved in looking at the plant, but not be aware of being aware of it. There is an experiential continuum at one end of which attention/awareness and the particular content of awareness are essentially merged, and at the other end of which awareness of being aware exists in addition to the particular content of the awareness. In between are mixtures: at this moment of writing I am groping for clarity of the concept I want to express and trying out various phrases to see if they adequately express it. In low-intensity flashes, I have some awareness of what I am doing, but most of the time I am absorbed in this particular thought process. The lower end of the self-awareness continuum, relatively total absorption, is probably where we spend most of our lives, even though we like to credit ourselves with high self-awareness.
The relative rarity of self-awareness is a major contributor to neurotic qualities of behavior and to the classification of ordinary consciousness as illusion or waking dreaming by many spiritual systems... The higher end of the continuum of self-awareness comes to us even more rarely, although it may be sought deliberately in certain kinds of meditative practices, such as the Buddhist vipassana meditation...
The ultimate degree of self-awareness, of separation of attention/awareness from content, that is possible in any final sense varies with one's theoretical position about the ultimate nature of the mind. If one adopts the conventional view that mental activity is a product of brain functioning, thus totally controlled by the electrical-structural activity of brain functioning, there is a definite limit to how far awareness can back off form particular content, since that awareness is a product of the structure and content of the individual brain. This is a psychological manifestation of the physical principle of relativity... Although the feeling of being aware can have an objective quality, this conventional position holds that the objectivity is only relative, for the very function of awareness itself stems from and is shaped by the brain activity it is attempting to be aware of.
A more radical view, common to the spiritual psychologies, is that basic awareness is not just a property of the brain, but is (at least partially) something from outside the workings of the brain. Insofar as this is true, it is conceivable that most or all content associated with brain processes could potentially be stood back from so that the degree of separation between content and attention/awareness, the degree of self-awareness, is potentially much higher than in the conservative view.
Whichever ultimate view one takes, the psychologically important concept for studying consciousness is that the degree of experienced separation of attention/awareness from content varies considerably from moment to moment.
Attention/awareness can be volitionally directed to some extent. If I ask you to become aware of the sensations in your left knee now, you can do so. but few would claim anything like total ability to direct attention. If you are being burned by a flame, it is generally impossible to direct your attention/awareness to something else and not notice the pain at all, although this can be done by a few people in the ordinary d-SoC and by many more people in certain states of consciousness. Like the degree of separation of attention/awareness from content, the degree to which we can volitionally direct our attention/awareness also varies. Sometimes we can easily direct our thoughts according to a predetermined plan; at other times our minds wander with no regard at all for our plans.
Stimuli and structures attract or capture attention/awareness. When you are walking down the street, the sound and sight of an accident and a crowd suddenly gathering attract your attention to the incident. This attractive pull of stimuli and activated structures may outweigh volitional attempts to deploy attention/awareness elsewhere. For example, you worry over and over about a particular problem and are told that you are wasting energy by going around in circles and should direct your attention elsewhere. but, in spite of your desire to do so, you may find it almost impossible.
The ease with which particular kinds of structures and contents capture attention/awareness varies with the state of consciousness and the personality structure of the individual. For example, things that are highly valued or are highly threatening capture attention much more easily than things that bore us. Indeed, we can partially define personality as those structures that habitually capture a person's attention/awareness. In some states of consciousness, attention/awareness is more forcibly captivated by stimuli than in others.
Attention/awareness constitutes the major energy of the mind, as we usually experience it. Energy is here used in its most abstract sense — the ability to do work, to make something happen. Attention/awareness is energy (1) in the sense that structures having no effect on consciousness at a given time can be activated if attended to; (2) in the sense that structures may draw attention/awareness energy automatically, habitually, as a function of personality structure, thus keeping a kind of low-level, automated attention in them all the time (these are our long-term desires, concerns, phobias, blindnesses); and (3) in the sense that attention/awareness energy may inhibit particular structures from functioning. The selective redistribution of attention/awareness energy to desired ends is a key aspect of innumerable systems that have been developed to control the mind. The concept of psychological energy is usually looked upon with disfavor by psychologists because it is difficult to define clearly. Yet various kinds of psychological energies are direct experiential realities. I am, for example, full of energy for writing at this moment. When interrupted a minute ago, I resented having to divert this energy from writing to dealing with a different issue. Last night I was tired; I felt little energy available to do what I wished to do. Those who prefer to give priority to observations about the body and nervous system in their thinking would tell me that various chemicals in my bloodstream were responsible for these varied feelings. But "chemicals in my bloodstream" is a very intellectual, abstract concept to me, while the feelings of energy and of tiredness are direct experiences for me and most other people. So we must consider psychological energy in order to keep our theorizing close to experience.
I cannot deal in any detail with psychological energy at this stage of development of the systems approach, for we know little about it. Clearly, changing the focus of attention (as in trying to sense what is happening in your left knee) has effects: it starts, stops, and alters psychological processes. Also, attention/awareness is not the only form of psychological energy. Emotions, for example, constitute a very important kind of energy, different in quality from simple attention/awareness shifts, but interacting with attention/awareness as an energy. So while this book deals concept of psychological energy is much more complex and is one of the major areas to be developed in the future.
Note that the total amount of attention/awareness energy available to a person varies from time to time, but there may be some fixed upper limit on it for a particular day or other time period. Some days, we simply cannot concentrate well no matter how much we desire it; other days we seem able to focus clearly, to use lots of attention to accomplish things. We talk about exhausting our ability to pay attention, and it may be that the total amount of attention/awareness energy available is fixed for various time periods under ordinary conditions.
