Our minds are model-making machines. Simple external world models we create for mechanical movements are true: we can predict rather exactly what will happen if we make some movement, for example, when we play tennis.
In our lifetime we create more complicated models of social environment we are acting in and the models of self living and acting into this world. Here is a problem: these models are partly correct but in some significant areas – simply false. They are reality-like, and we accept and use them. It is very hard to create even nearly true models of contemporary society we live in. Our false models create illusion of being true because our mind connects outer world events with the expectations we are using in accordance with our false models. That is why false beliefs, superstitions and religions are accepted and used.
We are doomed to live and act with inaccurate and false models of reality and ourselves. This is why since centuries human beings can not hand over to their offspring the art of happiness and successful living: we don’t have exact models of self and the society we are living in. In other words: we don’t understand ourselves, we don’t know who we are, where we are coming from and where we are going.
