Lines on paper are analogies.
We can use a computer to analogize to paper. Same enough.
What are lines on paper analogies of?
They are analogies of our thinking processes, solidified. They are analogies of stability. They are analogies to rocks holding up a house.
They are analogizes of concepts. They are analogies of mathematics. Mathematics is an analogy to movement. Mathematics is also an analogy to reality. Movement is an analogy to wiggling our fingers and toes, moving our arms.
Movement is an analogy to object permanence. If there was once a there and there is now a here, something stayed the same: The background. I’m analogizing the background to an object itself, within which other objects can go. Object permanence is also analogous to subject permanence: If that other thing is still there when I no longer see it, I am still here. If something is gone when I no longer see it, am I also gone too?
