Because the word 'self-awareness' is cumbersome, I'll make the following remarks about awareness. The same remarks will apply to self-awareness. The structure of language has a strong influence on how we think. How might we be influenced by the term 'awareness' being a noun? We tend to think of awareness as a thing, with some kind of existence of its own. It is only because of this that a statement like "awareness is not a link in any causal chains" can appear to make any kind of sense. Let's see what happens if we make awareness a verb. We define it in such a way that when we might have otherwise said that a brain has awareness, we instead say that the brain is awarenessing. Statements about causal effect of awareness, or on awareness, become statements about causal effects on the brain (which alter the way it awarenesses), and of the brain (where controlling output devices, ie. muscles is part of awarenessing.) If we have a definition of awareness, ie. a description of how to awareness in terms of simpler activities, we can check to see if a machine awarenesses. In fact, it's easier to check if a computer is awarenessing than it is with a brain, because you can trace the computer's program. You non-mechanists are only capable of tying mechanists into verbal knots, because most mechanists haven't awarenessed the effect on their thinking of using the word 'awareness' as a noun. (I owe the inspiration for the above to the book "Teaching as a Subversive Activity" by Postman and Weingartner. Much interesting stuff in there even if you're not interested in education.) -- David Canzi ACCUSE, v. t.
