Yes, the obvious things like air, water or wind are not what we believe or don't have to believe, it is our experienced reality, so we don't need a system to tell us about an air or water fact.

We adopt a belief as a child because it is also adopted by our caregivers and the cultural system that surrounds them. A part of it comes into the unconscious, another comes to the surface and that's what we are dealing with when we talk about it. The underlying may well contradict this.

In what other people have made us believe, we often recognize several facets, something coherent and something incongruous. When people like Richard Dawkins, for example, are in a passionate conflict with religion and carry out this inner conflict with the outside world and confuse that the coherent with the inconsistent in themselves leads to war, we recognize this in the doggedness and also partly open contempt or hatred. Alternating between an expressed superiority. However, the person does not know that he does not fight against external opponents, but merely follows an internal conflict, which he is only able to solve there.

Since man is inherent in "knowing" that he cannot survive alone, his perception looks for like-minded people and perceives them as "good", while those who are not like-minded present themselves to him as "bad". But since such a projection happens on the basis of a dualistic world view, this problem escapes him in his thinking. However, all observed pairs of opposites such as fire and water, gain and loss, objective and subjective, are merely a deception of the mind and lead to a sense of separation, because opposites cannot be separated in this way, since all opposites condition each other.

Buddhist teaching speaks of deception through the complexes of inferiority, superiority and equality. The latter is little known as a form of complex. But it is present in everyday life because people constantly compare themselves with each other. For example, someone is faster in running or better in arithmetic, one is ill and compares himself to a healthy person, the healthy person is happy not to be ill and so on. Such comparisons are based on pride and create suffering.

In fact, however, you can question your accustomed beliefs and investigate them. The moment you question one of your beliefs, examine it and check its coherence, you may be able to let go of that belief, which in my opinion results in a choice. But having made a choice does not bring you anything if you do not adjust it to other than the used habits and ways of thinking and acting in the world. It's a lot of inner work to do.
