A reader (!) asks: Does [what you posted about consciousness
yesterday three days ago] mean that we are only conscious of what’s going on in our brains?
That’s an excellent question. When I say that consciousness is certain kinds of brain activity or patterns of neural activation, it may sound like I’m saying that we’re only conscious of brain activity. In other words, we’re not conscious of the rest of the world or the rest of our bodies.
Given what I’m saying about consciousness, I might explain that we are “directly” conscious of our brain activity and “indirectly” conscious of the rest of the world. Or I could say that our consciousness of what’s going on in our heads is “immediate”, while our awareness of everything else is “mediated”, i.e. conveyed through intermediaries, such as the air that carries sound waves to our ears and the nerve impulses that travel from all over our body to our brain.
So when I raised this question yesterday (“Does this mean we are only conscious of what’s going on in our brains?”), I began by saying “in one sense, yes, because that’s where the physical phenomenon of consciousness takes place”. I then said, however, that in the most important sense our brain activity enables us to be aware of what’s happening outside our brains.
Actually, I recommend that we reserve phrases like “conscious of”, “aware of” or “what we experience” for the things we are ordinarily and importantly conscious of. That’s the standard way of speaking and the best way to describe what’s happening when we are conscious. For instance, when you’re awake, are you conscious of your surroundings? When you raise your arm, do you experience any discomfort? Now that you’re on Social Security, are you experiencing any memory loss?
Asking whether we are conscious of what’s going on in our brains amounts to asking whether we are conscious of our consciousness. It’s a misleading question. It’s like asking someone at the North Pole which way is north. To be conscious is to have a certain kind of brain activity. To be conscious of whatever is to be conscious of something other than your brain activity. That’s because there is no way to be conscious of your consciousness. There is no mechanism, no mental apparatus, no meta-consciousness that allows being conscious of consciousness. Consciousness just is. The world you see, that rumbling in your stomach, is what it looks like, feels like, to have the right kind of brain activity.
You can think about being conscious. We’re doing that right now. But that’s different from being conscious of consciousness. When you think about consciousness, you’re conscious of your thoughts (about consciousness), just like you can be conscious of thoughts about other things. But consciousness itself just is (I could say it is what it is, but that would be redundant and annoying).
Could an evil demon be tricking you, like Descartes wondered? Could you be a brain in a vat, like later philosophers ask themselves? Sure, it’s possible to be seriously wrong about what you’re conscious of. Maybe what you’re conscious of isn’t ever what you think it is. I’m not worried. You shouldn’t be either.
If a tree falls in the forest, does it make a sound? Yes, it makes the air vibrate and if it creates enough vibrations and there’s anyone around who’s conscious and isn’t deaf, they’ll hear (be conscious of) the crashing sound.
I’m not sure what I’ve been saying makes sense. I’ve thought about this topic for a long time but never expressed my thoughts this way before. Maybe what I’m saying is way off the track, but it’s all I’ve got right now. Maybe I’ll get back to it again. In the meantime, stay conscious.
In my opinion, that implies being conscious of other things, not consciousness.
