ature of consciousness |
Awareness is the consciousness of a thing such that there can be or is an appropriate response to it. |
Following this line of thinking, the conclusion we arrive at is that our consciousness is very limited. Furthermore, we are not conscious when we are sleeping with the point being that human consciousness has daily cycles of darkness and light: i.e. awareness and not. In addition, while consciousness heightens with energy and high emotions, it lessens to the state of unconsciousness even during waking hours with sickness, depression, and low energy states as hunger and thirst.
There is another angle to look at consciousness. The body is full of sensors in every square centimeter of external flesh: variously light, sound, touch, smell, and taste sensors. The body is bombarded with sensory stimulation every second of the day. We even feel the bed below us. But, though a flood of information comes continually to our senses (even the sound of our own breathing) we are aware of nothing during sleep and if one becomes parapelegic, they loose all sensation below the neck. However, in both sleep and paralysis, the same quantity of information comes to the senses. But, we are unaware of it. In this sense, we are conscious: but only when we are awake and whole. Consciousness, then, is partly a function of energy-level and sensory connectedness. Yet, of those adults both awake and whole, some will be more conscious than others. Thus, to say the human being has consciousness is a statement without but very much in need of qualification. It is even more true in the following.Though awake and whole the human has a limited window of consciousness as the new born and old and infirm are aware of precious little. A person with amnesia, one who is drunk or under the influence of drugs, or one who is catatonic or autonomic is but minimally conscious. It goes without saying that a person who is knocked out, one in a state of shock, or in a coma has no consciousness even though they are living people. In all the cases spoken of in the previous three sentences, a lowly mosquitoe biting anyone of these people or parasite locked into them has more overall functional and pragmatic awareness of its environment on a comparative and perhaps absolute scale than any one of them.
We are conscious but completely unconscious of experiences in the womb. We start as two entities: a tadpole-like sperm and egg. We have no memory of being formed as a sperm or egg. No memory of when the sperm or egg we came from was only 50% formed. No memory of ejection from our fathers. No memory of the nine hour marathon we won against billions of other competitors. We have no memory of swimming as a tadpole through the filopian tube to unite with the egg that became us. No memory of union with the egg. We are unaware of our experience in the womb. We have no memory of the first months or years of life even though there may be emotional imprinting in the sense that emotional experiences may assist in forming our dominant feelings and attitudes.
We are aware, but we are not aware of much. Awareness began when Nature gave us permission to be aware: after all the work to make us was done, the light switch was turned on and we became the most conscious things in the universe so the mythology goes. If there is life after death and has always been, it is belief and not a reality that can be measured. And, if it really does exist and one denies it, then that is a true irony of the limits of awareness.
Consciousness would seem to be a highly constrained and limited faculty with relatively little range but enough so as to be useful to function in the environment a thing exists within. Further, to be conscious of realities out of a things' domain would seem to be an unwanted extravagance for Nature to design and out of practicality would not. And this would only mean that human consciousness was appropriate, but not superior. The consciousness of any given individual is hardly a thing that we could call universal consciousness and is an infinitesimally small sliver of what could be called such. And there is infinitely more that we are unaware of than we are aware of particularly in the realm of disease as it begins first in one cell and we never know when. We are not aware of things what is happening now in each one of the 1014 cells in our body. Billions of photons of light are strike our eye each waking moment, but we are not conscious of them as they individually enter.
Those who applaud human consciousness as awareness of spirit, curiosity about the meaning of life, and such may not have made a big point. There is no insect or animal that once made aware of the greater questions would develop a longing for them. If we became a fly, we would likewise loose interest in such questions. On the otherhand, consciousness is a two-way street meaning lower animal consciousness and human consciousness are not mutually exclusive.
Oxford University Animal Behaviorist, Richard Dawkins, says of the self-awareness within cells (via its genes i.e. replicators) and between cells:Since we know the power this tiny central office has in the isolated cell, do they not resemble stations of local government dispersed throughout the body, communicating with each other with great ease, thanks to the code that is common to them? 1
Speaking in this case of more overall communication within and between cells, involving the input of hormones, Lewis Thomas, former Dean of Yale Medical School, writes:The first thing to grasp about a modern replicator is that it is highly gregarious. A survival machine (metazoan) is a vehicle containing not just one gene but many thousands. The manufacture of the body is a cooperative venture of intricacy.2
The body's CIA (lymphocytes) look for foreign agents (antigens) wanting to sabotage your body. Thomas presents the old medical idea in the following showing how indeed cells have self and environmental awareness:Hormones are sent off to react silently with cell membranes, switching adenyl cyclase, prostaglandin, and other signals on and off; cells communicate with each other by simply touching; organelles send messages to other organelles; all this goes on continually, without even a personal word from us. The arrangement is that of an ecosystem, with the operation of each part being governed by the state and function of all the other parts. When things are going well, as they generally are, it is an infallible mechanism. 3
Also concerning inevitable cell self-awareness, von Neumann, the father of the modern computer, using the cells of the nervous system as the model for the computer you use every day, wrote of cell malfunction:Lymphocytes are genetically programmed for exploration, but each of them seems to be permitted a different solitary idea. They roam through tissues, sensing and monitoring ... They carry specific information in their surface receptors, presented in the form of a question: is there anywhere out there, my particular molecular configuration? ... Lymphocytes are apparently informed about everything foreign around them. 4
The conclusion, then, to draw of this section is that the body is self-aware. The organelles, replicators or genes, cells and systems are in a state of continual communication and awareness. In size and mass, compared to the beacon of light, the lighthouse is an utterly enormous structure, the beacon so very tiny by comparison. The human, like a lighthouse made of bricks of cells shining its light of consciousness outwards from the beacon of its eyes into the night-darkened oceans of the world, the human is aware of nothing of its own construct nor the constant activities that are undertaken beneath its skin to keep the human organism functioning each second of the day, every day of the year, and every year of his or her life. It is ironic: the human consciousness we brag so much about is 99% unconscious of its inner self.There never occurs a [cellular] malfunction which cannot be corrected by the organism itself, without any significant outside intervention. The system must, therefore, contain the necessary arrangements to diagnose errors as they occur, to readjust the organism so as to minimize the effects of error, and finally to correct or permanently block the faulty com-

The question raised by Dawkins, metaphysical in nature, yet certainly logical to the point of being inevitable (especially from the view of non-locality: click), is that indeed, there are other conscious' than the human and consious' that consciously created the human and other living entities simply to enhance their own survival. Yet, Dawkins is not alone in this line of thinking (other conscious' and purposes) for Lewis Thomas writes of the history of the living cell. The cell shared by plant and animal have common organelles (a cell's organs) that were once individual creatures that perhaps three billion years ago one-by-one inhabited and were reproduced along with what became the plant and animal cell. Thomas likewise considers the possibility that metazoans such as ourselves exist for the purpose of the creatures colonizing us: and if we do, we are unconscious of the intelligence that formed us in the sense that we cannot conduct a conversation with it or intuit its present and ongoing thoughts.The packaging of living material into discrete vehicles became such a salient and dominant feature (imposed on life by replicators), that when biologists arrived on the scene and started asking questions about life, their questions were mostly about vehicles individual organisms. The individual organism came first in the biologist's consciousness, while the replicators now known as genes were seen as part of the machinery used by individual organisms. It requires deliberate mental effort to turn biology the right way up again, and remind ourselves that the replicators come first, in importance as well as in history.
One way to remind ourselves is to reflect that, even today, not all the phenotypic effects of a gene are bound up in the individual body in which it sits. Certainly in principle, and also in fact, the gene reaches out through the individual body wall and manipulates objects from the world outside, some of them inanimate, some of them other living beings, some of them a long way away. With only a little imagination we can see the gene as sitting in the centre of a radiating web of extended phenotypic power. And an object in the world is the centre of a converging web of influences from many genes sitting in many organisms. The long reach of the gene knows no obvious boundaries. The whole world is criss-crossed with causal arrows joining genes to phenotypic effects, far and near. 7
| A good case can be made for our own non-existence as entities. We are not made up, as we had always expected, of successively enriched packets of our own parts. We are shared, rented, occupied. At the interior of our cells, driving them, providing the oxidative energy that sends us out for the improvement of each shining day, are the mitochondria, and in a strict sense they are not ours. They turn out to be little separate creatures, the colonial posterity of migrant prokaryocytes, probably primitive bacteria that swam into ancestral precursors of our eukaryotic cells and stayed there. Ever since, they have maintained themselves and their ways, replicating in their own fashion, privately, with their own DNA and RNA quite different from our own. They are as much symbiants as the rhizobial bacteria in the roots of beans. Without them, we would not move a muscle, drum a finger, think a thought. Mitochondria are stable and responsible lodgers and I choose to trust them. But what of the other little animals, similarly established in my cells, sorting and balancing me clustering me together? My centrioles, basal bodies, and probably a good many other more obscure tiny beings at work inside my cells, each with its own special genome, are as foreign, and as essential, as aphids in anthills. My cells are no longer the pure line entities I was raised with (hairy sub-men, ape-like); they are ecosystems more complex than Jamaica Bay. The usual way of looking at them is as enslaved creatures, captured to supply ATP for cells unable to respire on their own, or to provide carbohydrate and oxygen for cells unequipped for photosynthesis. This master-slave relationship is the common view of full-grown biologists, eukaryotes all. But there is the other side. From their own standpoint, the organelles might be viewed as having learned early how to have the best of possible worlds, with least effort to themselves and their progeny ... My mitochondria comprise a very large portion of me. I cannot do the calculation, but, I suppose there is almost as much of them in sheer dry bulk as there is the rest of me. Looked at this way, I could be taken for a very large, motile colony of respiring bacteria, operating a complex system of nuclei, microtubules, and neurons for the pleasure and sustenance of their families, and running at the moment, a typewriter. I am intimately involved, and obliged to do a great deal of essential work for my mitochondria. My nuclei code out the outer membranes of each, and a good many of the enzymes attached to the cristae must be synthesized by me. Each of them, by all accounts, makes only enough of their own materials to get along on, and the rest must come from me. And I am the one who has to do the worrying ... There they are, moving about in my cytoplasm, breathing for my own flesh, but strangers ... If I concentrate, I can imagine that I feel them; they do not quite squirm, but there is, from time to time, kind of a tingle. I cannot help thinking that if only I knew more about them, and how they maintain our synchrony, I would have a new way to explain music to myself. There is something intrinsically good-natured about all symbiotic relation, necessarily, but, which is probably the most ancient and most firmly established of all, seems especially equable. There is nothing resembling predation, and no pretence of an adversary stance on either side. If you were looking for something like natural law to take the place of 'Social Darwinism' of a century ago, you would have a hard time drawing lessons from the sense of life alluded to by chloroplasts and mitochondria, but there it is. I like to think that they work in my interest, that each breath they draw for me, but perhaps it is they who walk through the local park in the early morning, sensing my senses, listening to my music, thinking my thoughts.8 |
