Position & movement

If it is assumed that no two observers can be at the same place at the same time, then no two observers ever have the same surroundings. Hence, the environment of each observer is “private,” that is, unique. This seems to be a philosophical puzzle, but it is a false puzzle. Let us resolve it. One may consider the layout of surrounding surfaces with reference to a stationary point of observation, a center where an individual is standing motionless, as if the environment were a set of frozen concentric spheres. Or one may consider the layout of surrounding surfaces with reference to a moving point of observation along a path that any individual can travel.


Shifting perspective

“You discover how confounding the world is when you try to draw it,” Tan says. “You look at a car, and you try to see its car-ness, and you’re like an immigrant to your own world. You don’t have to travel to encounter weirdness. You wake up to it.”

To inform

We are told that to perceive something is to categorize it, to distinguish it from the other types of things that it might have been. The essence of perceiving is discriminating. Things differ among themselves, along dimensions of difference. But this leaves out of account the simple fact that the substance, place, object, person, or whatever has to last long enough to be distinguished from other substances, places, objects, or persons. The detecting of the invariant features of a persisting thing should not be confused with the detecting of the invariant features that make different things similar. Invariants over time and invariants over entities are not grasped in the same way.
