On the other hand, total transparency of perception, understanding and in the ability to act, would be like some have imagined God's powers: all knowing, all detecting, all powerful... not a single event, in every scale and in every dimension, would occur that would pass unnoticed, not a single will would pass unfulfilled. Obviously, human beings, are unimaginably far away from such total transparency, our windows of perception are very limited due to constrains in our bodies (sense organs and cognitive powers) and in our interests. But however restricted our interests may be, we must care about transparency as long as we care for anything at all. Even if we wanted to commit suicide we would have to be clear on ways to achieve it! Only utter contempt towards every kind of existence / experience would be compatible with disregarding clarity in all its forms. (The movie Cast Away suggests such a state of mind when Tom Hanks, lost at sea, looses "Wilson".)
We should notice that if we go a step further and imagine everything to be perfectly transparent in every way, not only the medium that allows subject and object to communicate, but the objects themselves, then what would we see? Apparently we would have to say «nothing», because everything we see with our senses has a shape, it interferes, it opposes our senses or instruments, it is by "kicking back", by interfering with its environment that we can identify it and characterize it. We live in a world of actions and reactions. But if everything was absolutely transparent our senses would not be able to interact with any particular thing, they would not "kick back", no frontiers could be delineated, nothing would respond to our actions. It seems we would be blind, this time not from being confined by opaqueness, but from being lost in infinity. Only the conjugation of clear media and opaque objects can provide a world of objects to our senses.
