We really do not really think about how we as a species perceive the world. We see, we hear, we sense and all that good stuff, and we merely think that it all combines in the think tank that is our skulls. We merely form our judgments by using that think tank and call ourselves conscious. However, when visiting Hume, one may begin to question their own senses and take what they see with a grain of salt.
To those unfamiliar with the philosophies of Hume, I shall place a brief video below for a quick crash course. However, for more practical readings, I do suggest that you read his pieces.
Now, as stated within Hume is the fact that the human experience is not perceived in the general idea that we have it, but is merely the separate apparatus merging into one singular "perception" of one. So, when you are staring at the cat in the hallway and hear it meow or mew, you are not perceiving the cat in one singular self, but only observing it separately from one another, in this sort of phantom zone.
This does seem to be bizarre to myself (which is hilarious to Hume, because there is no singular self), namely because where and why we perceive ourselves as individuals is not known. The phantom zone itself is something that we cannot truly understand, simply on the basis of our own identities. Why craft identities for the floating consciousnesses, and is there even consciousness when we are left with the floating senses?
The question is that I truly doubt that we are not what we are. This not because of the floating senses. That is merely a simple idea where several senses come together to form a single stimuli. The sense may even interchange with one another, making it possible that we have no singular self. It merely is because of the idea of seeing ourselves as an individual, rather than becoming something that is different.
It really comes down to why we form identities. Why do I call myself, myself and why can I call out to another individual. There just doesn't seem to be some overarching sense to the general idea. In the end, all I see is what I see, not what my senses see and not what other senses see.
