Can you be hungry without noticing it?
If you give it a quick thought, you’d probably say, Sure. Why not? What if you get caught up in a task that really takes all your focus, and you don’t eat for a few hours, and then when it’s done you suddenly realize your stomach is growling and grumbling. You’ve clearly been hungry for a while!
That’s from a quick thought.
But then think about it a little more slowly. What does it mean to be hungry? The body needs food? Sure. But what if you were in a coma, let’s say? Or–to really get to the extreme end of the thought experiment–what if you had your brain completely separated from your body and put into a glass jar? Your brain was wired up to still survive and think, but you were no longer connected to any physical sensations in the body.
Would it be possible to be hungry? Is hunger merely a physical state of the body–like being diabetic, or being constipated (sorry)–or is it a state of mind that is dependent on your perception of that state of the body?
Suppose the brain in the jar was poked and prodded with electrical circuits that simulated the feeling of hunger. Being completely disconnected from the body, the feeling would have no correlation with the state of the stomach. It’s pure sensation.
Again, can you feel hungry without noticing? Do you have to notice a feeling to feel it?
Think about your answer, and then reflect on how that could apply to other feelings besides hunger: Being cold. Being tired. Being uncomfortable. And even more purely mental states: Being nervous. Being sad. Being bored.
If you can’t feel something without noticing it, then does that mean the feelings only exist in awareness?
And if so, are they “real?”
