notes on awareness, memory, language, and reality. by francesco ranci 18 June 2002 09:53 UTC |

Starting from the last point: - I think we are usually not aware of what is going on while we perceive something, because it's an extremely fast set of processes, we do not have much of a theory about it, and (last but not least) in our everyday activities we are interestet in the results of such processes (as opposed to being interested in how such processes may be understood and described). For example, if I am thirsty I get myself a glass of water (I do not start asking myself: "how did such sensation of "thirst" arise in me ? How come that I know I'm supposed to perform an activity called "drinking" in order to extinguish it ? How do I distinguish a "bottle" from a "glass" or a "fork", and "water" from "vinegar" or "potatoes", and so on). By the way, this basic unawareness helps explain in my view how the tradition theory of knowledge went of the tracks and a whole set of metaphors came to the fore (including the mirror metaphor). The explanation goes as follow: the human being is used to relate and compare the results of mental activity in order to survive. He has to learn that the "sun" warms up and may burn up your skin and so on. So, when he asks himself how does he "perceive" something, he follow the same methodology and tries to establish a relationship between himself and what he perceives, not realizing that both already are results of his mental activity (something that he is not aware of, after all - from this point of view of course). Ernst Mach (1889) said more or less that "I" and "Thing" are "useful fictions", and they surely are, but not for every purpose. Mach proposed his "elements", of which both "I" and "Thing" can be analysed. That was ain important step on the way to a reliable theory of knowledge I think. We can, however, become aware to a certain extent of such processes, I believe. - Memory: memory is repetition of mental activity (another misleading metaphor shows up here, i.e. the "storage" metaphor). Again, we are not aware of the process (for example, hoe do we recognize a face or an object ? All I would say is that we may feel a set of processes starting up "again" in our brain, and of course we are not always right). In order to verify if we remember something correctly, we do not compare it with an impossible (in my view) "reality-as-it-is": on the contrary, we put together a narrative based on more comparisons, consistency, knowledge that we have about the things involved, and so on. It is interesting on this point to note how easily any of us can get confused about his memories by a lawyer in a trial, for example (or in similar situations). - "Closed circle" (?). Well, I see it as a circle somehow (self referential circle) because we see what we already know and we know what we see. But, we are talking to each other now (somehow) and we do understand each other everyday, at least just enough to cooperate more or less. So the circle is open. When we are born our mothers guide us with their words to pay attention to what happens in a certain way and use certain words to express what’s happening according to us. When my son was learning his first words, I used to come home from work at a certain our (as I do now), and my wife used involve him in the celebration the event by happily screaming “Daddy in home ! Daddy !”. As a result, for a while every time my son was excited about something he said “Dada ! Dada !”. He also used to use the same word (“Mama”) for mother and for “banana”, and my interpretation is that as he was breastfeeding he found enough similarity between his mother and bananas to justify using the same name. There are so many other examples of how children learn how to talk and gradually build a memory that it’s not only their own, because they have to use a language that is shared. - Reality. A reality check comes from repeting ourselves a set of operations. So I know how to make myself a cup of tea when I can repeat the set of activities that allow me in the end to have a cup of tea. However, someone may say that what I make is not a "real" cup of tea. So, we usually have to have a social agreement about what is "real". My son quickly learned how to express his excitement in different ways than by saying "Dada !", in order to be better understood. The history of science is obviously a good source of inspiration on this issue, but not the only one. - Senses/Brain. Another contraint on the process of contructing our reality is the way we are biologically made. I agree with that. You could never teach a shellfish how to sing "New York New York"... Or, as a more intelligent example: in order to teach chimps a language that was more similar than theirs to our language (so that we human could understand them a little better) it was necessary to rely on sign language and computer keyboards. They are learning a lot, but I do not know how far they can really get on the way of sharing our cultural habits. The same applies to computers, with the obvious difference that they are not even alive (whatever that means) yet. __________________________________________________ Do You Yahoo!?
