It is much easier to deny the truth of what we are looking at than face it. In Visual science we call this a suppression. If we feel uncomfortable with what we are looking at, that is, we cannot understand, then we have a central suppression. If our feelings are affected, that is, we do not know what is being seen, then we have a peripheral suppression.
Turning a blind eye from the brain is an innate survival strategy. It is the basic function of the brain. Consciousness is facing what we are looking at and seeing. It is being present in awareness. This is our task. To be human is to evolve our consciousness to such a degree that we face our challenges and problems. We look, we work out a logical strategy. We see possibilities that feel correct and make sense. In doing so, we build a set of experiences that advance our wisdom for living.
