Pure perception and the extra layers of meaning

There is no such thing as pure perception.
All we perceive has an added layer of interpretation and prediction.
In fact this layer goes so deep that we can only be aware of the fact that we are actually predicting things when these predictions are violated - like in the case of visual illusions, or impossible objects.



In this case our "perceptual" system extrapolates an object that is not truly there, but it might be (in a normal world when someone has not created a perceptual trick) - a triangle. As soon as we run our gaze over the edges we realize this couldn't possibly be, as it defies what we know about space.

This extra layer of perception is actually interpretation, and comes from our need of being able to predict the world and categorize it in things that we already know. It is a much harder to notice this layer when we deal with abstract interpretation of events, situations and people. As these rarely can provide exactly the circumstances that would violate those expectations, and even then we can reinterpret that violation under our own system's rules, or simply discard it.*

*Remember it is very hard for people to hold on to contradictory facts; we like things and facts that are coherent, and our brain will do lots to get that coherence, including brushing over very important details that don't fit the big picture, or - well - lying to us to keep our coherence and perception of our normal image of the world going.

It is fascinating to think about the fact that we deal with synthesis, inference and abstraction from the moment we open our eyes (or sensory gates), and that what we think of as being "abstract thought" has in fact roots and examples in our very mundane, anchored-in-the-concrete interactions with material objects of the world.

I call this interaction because even if we don't act on the object we are observing, we already have a predesigned cognitive system that deals with it in such a way as to make it available for our interaction. We can't have pure observation, our level of observation already involves some level of preparation for interaction.
There is no point in seeing the three lines that we perceive as a table, if there is no possible interaction with it. The layer of meaning of the object seems to be added for our possible interaction. What does that say about the ones fascinated with meaning? What is their stance on interaction?

The fact that we seem unable to have "pure" perception also makes me wonder what do those awesome people that are mainly observers actually see (yup, I mean you)? Are they the mirrors of the world, a special mirror, with the properties of their vision and interpretation, in which one can see the world reflected in their personality?

That is why we have such ambiguity with terms like vision - to see but also to have a vision of something. Having a vision is quite similar to having some higher degree of interpretation and meaning over the facts that you know, is being able to put them together in a way that makes them easy to navigate and inspires people to action and interaction.

We can only decide to interact with what we see in our vision.
