Great question. I think a lot of the variety in the answers comes from differing (implicit or explicit) interpretations of the word consciousness.
Meatbot: A dog is less conscious than you. A flea is less conscious than a dog. A microbe is less conscious than a flea. At each level they have less introspection, less analysis, a smaller range of thoughts, less "smartitude".
Less conscious = less complex analytic thought.
Jarle: Now, suppose you are forced to intensively focus on your surroundings, as if you were escaping in fear or desperately looking for something. You are in a larger degree disallowing your thoughts to reflect on the self as an entity. Higher intensitivity will result in lesser degree of self-reflection and self-consciousness, and taken to the extreme it will be comparable to a creature lacking self-consciousness.
More intensely conscious = less self-conscious. (Thinks: what about intense embarrassment versus drowsily absorbed in gazing at a landscape.)
Ferris_bg: Personally I think while you are under stress, you are actually less conscious. If you meditate you can achieve different forms of consciousness too, which should have lower value than your normal state (time passes quicker as you forget about it). [...] Before different incidents a lot of people report that "thousands of things gone through their mind for less than a second" (time passes slower). Maybe in that period of time this person was more conscious.
More conscious = more thoughts per second. Stress and meditation examples of less conscious states. (Thinks: some people who’ve been in a life-and-death situation--very stressful--report intense and detailed thought, taking in information and being able make decisions in less time than normal.)
Brainstorm: Nevertheless, although ignorance/unconsciousness is bliss in this sense, [...]
Less conscious = knowing fewer facts or being less wise.
Meatbot: If you are in the zone, you can't be thinking about how unhappy you are.
“The zone” = less conscious, at least by Brainstorm's definition.
Goethe: I do not think that being less conscious makes us happy, per se. I think being less self-conscious makes us happy. When you're 'in the zone', you're still very conscious -- in fact, you're hyper-engaged and thus hyper-conscious. But you lack cognizance of your consciousness.
More intensely conscious = more conscious. And less self-conscious states can be more intense. (Similar to the distinction Jarle made, except identifies consciousness with greater intensity, rather than more focus on self.)
Goethe: When self-discovery types talk about meditation and Zen and whatnot, this is what they're referring to - becoming 'more conscious' by becoming less self-conscious, ultimately achieved by training yourself to focus.
Meditative state (in the Oriental sense) = more conscious. (The opposite of Ferris_bg’s scheme, probably because Ferris_bg, like the OP, identifies consciousness with analytic thought.)
Brainstorm: But it actually suggests why self-reflection is a useful method to achieving better non-self-conscious consciousness.
More self-consciousness can lead to more consciousness as such? (But this is probably not more consciousness in the absolute sense that I think Goethe meant, more intense consciousness as such, and perhaps a simpler state of consciousness, but rather consciousness in Brainstorm’s sense of posts #4 and #14, knowing more facts or being wiser, the latter definition being closer to that implied by Ferris_bg and Meanbot’s original post.)
Goethe: So the answer to OP's question, I think, is this: go try some speed.
Caramon: Do LSD and you'll realize what "more" is like. :P
Galteeth: The only thing I can think of that felt like more/less conscious was my personal experiences with MDMA. I would say that being under the influence of MDMA felt like being "more" conscious then normal,
More conscious = more intensely conscious and/or more alert.
Brainstorm: I think it is more like physics, or other knowledge, can help raise your consciousness/awareness of certain things that were always happening "right under your nose." A middle-school teacher was telling me, for example, that she asked students to study their toilets and write down how they thought they worked. She said the responses she got for this assignment were widely varied. Probably many of the students had never thought about what causes a toilet to flush. Someone who understand physics, however, might be able to assess how the toilet actually works and would therefore be conscious of more than someone who just knows that it does work and leaves it at that.
Consciousness = knowledge of facts, or the greater variety of thoughts that results from this knowledge. Or is there a thematic connection between the novelty of directing thought at plumbing wonders and the way tripping derails your thinking habits letting you notice surprising new aspects of familiar things.
mr. vodka: Hm, interesting thread. So it seems we got three aspects we're discussing:
S: Selfconsciousness
C: Consciousness (of your surroundings)
A: Awareness (without necessarily realizing it, esp. when you're working on instincts)
Interestingly enough, due to earlier comments, it indeed seems like higher S will generally reduce A (and maybe C); lower animals, on the other hand, are very aware, yet completely lacking in S. It also seems like C can only appear when S is present, implying you're somehow relating the exterior world to your self.
I like the idea of teasing out the different phenomena that people are discussing here. It would be good to sharpen some of these definitions, particularly as the words consciousness and awareness aren’t necessarily distinguished in this way in everyday English. If someone is deeply absorbed in their surroundings to the point that they’re only dimly aware of themselves, would that be an example of C or A? Does surroundings include the imagined surroundings of a dream?
Ledicarus: First what is your basis for animals not having S, since we do not speak "animal" we can not know if they are self conscious.
Very good point.
Meatbot: Let's say I'm a major league ballplayer and I'm at bat. I am laser focused on the pitcher and the ball. So your focus is narrow but deep. You don't notice anything else around you. You are more conscious of the pitcher, but less about everything else. In a way you are more conscious than in normal life, but in a way you're less conscious. But in either case you are aware of yourself.
Good example. Some people describe similar experiences of intense focus in terms of being less aware of themselves, e.g. Goethe in post #7. What a sportsperson is focused on involves their own body and reactions, so I wonder if it’s less common to talk about being in the (sport) zone in that way. But think of all those anecdotes about someone in an emergency situation who risks their life or does something spontaneously with all their attention focused on the situation and others involved. Sometimes they only become aware of (what you would expect to be) a painful injury after the event. People also talk about being absorbed in art, a film, say, or carried away while listening to music. Some people also talk about loss of self due to drugs or meditation; on the other hand, some describe such experiences in terms of a fresh and more general insight into what self can mean...
Meatbot: Is laser focus more conscious than sitting on the beach soaking up lots of varied stimuli? I don't know.
Nor me. It’s an interesting question though. I'd be inclined to side with the "more consciousness = more intense experience" faction, including any kind of intensity, be it focused on one thing or flitting rapidly or making connections between a wide variety of things. That seems the most natural definition. After all, we already have less ambigious words like knowledge and wisdom and intelligence for those other concepts. Perhaps an example of being very much less conscious would be a state on the edge of sleep where I'm experiencing many rapid but faint impressions. But I'm not sure if this is actually a lessening of consciousness/awareness/experience/subjectivity itself or only seems like that because it's hard to remember and conceptualise. (Of course dreams can be intense experiences.)
Meatbot: So now let's compare the above to the experience of a deer tick. It could be focused or unfocused but is still considered less conscious than we are in either case. Why?
A cynical answer: We value consciousness (it’s what we believe distinguishes us from our closest non-human rivals, computers). We also value ourselves above ticks. We know consciousness has something to do with brains. We have fancier brains than ticks do. For these reasons, it’s natural for us to think that we have “more” or this valuable and value-conferring thing than ticks.
Meatbot: What if it's hyperfocused and only thinks "bite that thing", "poop" or "tired" all the time and basically cannot think anything else? I suppose the opposite would be thinking very little about a wide variety of things. Not sure what that would be though.
The internet?
Brainstorm: The baseball player is actually conscious of much more. Ever see the movie, "the Fan," with Wesley Snipes? He must be conscious of his average, the politics and pressures surrounding his average, etc. A hitter has to consciously block out chanting from fans and harassment that he would otherwise be conscious of.
If he’s able somehow to ignore these distractions without too much conscious effort, he’ll probably perform better. If he is acutely conscious of all those things, he’s not in the famously useful state of mind Meatbot described (#24), what Goethe called the zone (#7).
