huh. where to begin.
let’s start with the title. i had a flash in a pub a week or two ago about the definition of consciousness. i’ve always found that discussing consciousness was incredibly difficult because no one ever knew to what they were referring. then i thought about what makes me say “i’m conscious.” i realized that it was my ability to translate thought into language. so there’s my definition:
consciousness - n. - the ability to translate thought into language.
now, that leaves the undefined terms “thought” and “language”. i think we can agree, though, that these are things that differ in degree rather than in kind among things we might consider conscious. a computer, for example, could have a bit read as a thought. or something more complex, like a floating point addition. a bee could have “food is present” as a thought.
language, too, differs significantly in complexity. bees communicate through movements. we have vocal and sign languages (someone mentioned vocal thought being required for consciousness – deaf people think in sign language). whales have complex calls and songs by which they communicate. all these things are, to a degree, conscious, and it seems that we as humans measure the degree of consciousness by the degree of complexity of the thoughts and languages involved.
several people here seem to be arguing that “canned responses” are somehow insufficient evidence for conscious thought, or self-awareness (or any number of other things–there seems to be way too much switching of words and definitions in this thread for me to get a good handle on it all, and i think this area calls for precision). however, at least one of those same people have argued that on a fundamental level, humans do nothing but produce canned responses based on, presumably, a much more complex set of processes. considering that, is it difficult to believe my last sentence in the previous paragraph?
on to self-awareness: there are two things that are necessary for self-awareness. recognizing oneself in a mirror is not one of them. they are this: having a definition of self, and being able to recognize the object defined as self from other things. an octopus, for example, could not be self-aware by our definition, since if we held it to our standards, its arms are part of itself. since octopuses have no bones, and can’t process the huge amount of information that would be required for them to have a sense of where their arms are, their arms are largely autonomous, and they can only tell where their arms are by looking at them. octopuses, however, are also very intelligent. they have demonstrated problem-solving skills (like uncorking a jar containing a crab) and memory (by improving the time during which they go through a maze, for example). they may have a different definition of self than we would give them. their “self” might not even end at their arms. they may be able to recognize objects and delineate the world around them. i would say, then, that they are self-aware.
given that, i think self-awareness is largely irrelevant in any discussion of consciousness and conscious thought. it seems to require an arbitrary distinction. myself, i don’t even think i have an expressable definition of “i” or “myself” or “me”. where do i begin and end? it’s a question that probably must be answered to some extent before i can say “i am conscious”, but only to the extent that to whatever i refer as “i” can produce thoughts and express those thoughts through language.
does anyone think there are conscious phenomena not encompassed by my definition? i’d very much like to get the opinions of others on it.
