Where am I?

YOU, my friend/lover/enemy/self/anyone who's reading, are at the centre of the universe.

Here's a little tale from Sartre to help us out: A man takes a walk in the brisk morning air and enters a park, he is pleased in surveying his surroundings, perhaps he notices the way dew renders the area of leaves it sits upon silver, perhaps he is aware of the morning calls of various birds, perhaps he is relishing the crunch of the gravel under his feet. He walks for a while, observing the area. And then he notices another person enter the park and is threatened: he is no longer the centre of consciousness in the scenario. The other person is like a black hole sucking in sensory stimuli, equal and opposite to the protagonist. In fact, this other person renders our protagonist an un-protagonist, just another player vying to be in the centre.

Similarly I think there is a general fear most people harbour towards other people. We don't know what's inside their heads, we can only glean some inferences by noticing what gets sucked into the edges of that black hole and what occasionally gets spat back out. Who knows what that person thinks of you? Who knows how they really feel towards you? It's frightening, it's alienating. It renders us all equal.

I'm going to inject a bit of science in at this point. Because we live in an infinite universe, every point in the universe is the centre of the universe.
Six inches behind you head parallel to your eyes IS THE CENTRE OF THE UNIVERSE!
That same spot behind my head IS THE CENTRE OF THE UNIVERSE!
The tip of a rock resting in the Gobi desert IS THE CENTRE OF THE UNIVERSE!
Some place somewhere in outer space that has no name IS THE CENTRE OF THE UNIVERSE!
ALL AT ONCE!

Now I'm gonna chuck some metaphysics into my idea soup: your consciousness always inhabits a place in space, because your consciousness resides in your body. It's not often that people experience life externally from their bodies (although it has been known to happen). Wherever you go, there you are! Your consciousness is with you when you walk down the street, get on a bus and ride all over town - it moves with you. There isn't any physics that can locate exactly where in your body your consciousness resides, but it's in there. And that elusive space is ALSO the centre of the universe.

So really there isn't much need to be frightened of that impossible yet rationally true space in other people. You may not know what it looks like to be someone else looking at you, but you know what it is like being you looking at someone else (it's the same equation but inverted), so you know the processes.

Finally here is a little bit of magic to make it all stick together nicely: you need to come closer towards you own self to understand somebody else. It seems to me that if we're all parallel in our capacity to perceive and we're all simultaneously at the centre of the universe there isn't much separating the way that we function. Because we're in our own heads, it's best to try and understand who we are, and then we can know that the same thing exists in everybody else. It's our outlook that builds walls.
We can either see each other as competitors or companions... which I suppose we do already.
