Hi,
Sorry for my late response. I did not receive a notification that you had replied, even though I usually receive a notification when someone replies. I just checked back today thinking that I would remind you that you had not responded, only to find that you responded 2 weeks ago.
Is this your (general) opinion?
Yes, but it is also the opinion of the scientific consensus, and it is the opinion of almost every person in the world. So in that sense it is an objective fact. ie If someone says "I" and you say "Who? Please point to the person you are referring to", then of course they will point to their own body. Ask them where that object starts and ends and if they are not wearing anything they will indicate that it includes their skin and everything inside their skin. I'm sure you'll agree that this would be the result of an objective scientific trial.
How do you know this is absolutely true?
The only absolute truth is that there is unity (the number one). Everything besides that can only be defined and can only exist relative to something else. That statement is unfalsifiable, since it must necessarily be proven true by any experiment. Every alternative hypothesis is incoherent (contradicts itself).
How would you put yourself into an other persons position? Or is this just a thought?
It's a kind of geometric (mathematical) translation. It involves taking one's own sense data and transforming it with an algorithm, resulting in the imaginary sensation of seeing the world from another location/orientation. It's just a thought.
Direct Experience. This means you can only use your senses: smell, touch, sight, hearing, tasting.
There are three types of conscious cognition- recalling memories, directly experiencing the present, and imagining possible futures. No discussion between people can occur without utilizing all three. I assume you are not asking me to reply without using my memory, and without imagining that I hear my own voice in my head (thought).
is there an 'I' who is looking. Can you find a separate self that does the looking for you?
Verbal thoughts such as you mentioned are imaginary sounds. Looking at the object you mentioned is direct experience. Just as we can see and hear simultaneously, we can look at an object and imagine hearing sounds simultaneously. Both are processes of the object I refer to as "I", as are subconscious processes that I am not aware of. (Subconscious processes are an aspect of a person but the person is not aware of them.)
or are you then referring to a thought again?
Yes. It's all thought. The self is not the thought, it is the object that others refer to when they point at you.
Maybe you're asking me to imagine that I am a baby again, before I reach the mirror phase. At that time, I could see my own arms and legs, but I considered them as foreign objects just like the table in front of me. At that time "object" meant only a two-dimensional bundle of visual data that existed only while in my field of view. I did not posit the existence of a "self", nor did I posit an objective world. Only the experiences existed.
That is a solipsistic view. But if you want to take that view then I will ask you to agree that you are only a bundle of sense data in my mind, and have no existence independent of my mind. All meaningful discussion between people starts with the assumption that there is an objective world with many minds, each experiencing the world from a different location/orientation.
Can you experience a border between what you call you, and what you call the whole universe?
How does this border look like?
What I call "me" is the same object as what others call "you". Often people will unrealizingly include clothing as part of that object, but if you ask them to think more precisely they will agree that the real you is the skin bag inside the clothing. Of course, the skin, arms, legs, and other non-vital parts could be cut away, and only the remnant would be considered the person. But as long as the other cells are connected, then they are part of the person. As for symbiotic organisms (gut flora and fauna, mitochondria), I would say they are not part of myself. As for non-cellular material such as water, it is part of me as long as it is inside my skin. That means the saliva in my mouth is part of me, but if I lick my lips it is no longer part of me.
