Every Human being constantly processes information during his cognitive activity. Once this information is systematized (generalized), it acquires a new status — now it’s knowledge (“life experience”) of this particular Human being.
That’s why people reflect (“see”, feel) the outside World, and each of them does it in his/her own way (from his/her own “point of view”, “with his/her own eyes”).
Every person admits the existence of only those things he underwent by himself, then thought through, turned over in his mind, thought out, passed through, felt out, created, etc., that is, he cognized and realized something without any assistance.
If a human being did cognize and did realize “something”, then this “something” definitely exists for him!
If a human being didn’t cognize and didn’t realize “something”, then this “something” doesn’t exist for him at all!
All systematized and generalized feelings of a person are his consciousness (memory). There can be nothing more! This is the World of a human being he “lives” in.
P.S. If we imagine a meeting of two people, whose consciousnesses contain completely different information, they will not be able to communicate with each other, since they will have nothing to talk about, because these interlocutors live in “different Worlds” (they perceive the World “with different eyes”).
Here we would like to begin from the beginning, i.e., from elements of the Universe. Who is an immortal citizen of space? It is its atom. An atom – not the one known in science, but a true one – an indivisible particle, matter. Is there any of such? Hardly so. Let’s refer to scientific facts. All so-called atoms (92 items) are composed of hydrogen. Hydrogen itself is complex. But there is also aether. It consists of extremely small particles. It is possible that all matter, i.e. all other atoms, consists of them.
A true atom is unknown. One thing is observed: the simpler the atom, the more difficult its disintegration is. The most massive atoms decay in thousands of years and even less. Less massive ones – in billions of years. Even more common – in billions, trillions and decillions of years. Particles of hydrogen and aether may be of this kind.
Matter is a carrier of sense, since there is nothing but matter. What then we can attribute a feeling to? Where the matter is, where the atom is, there is a feeling. Atom or a part of it can be called primal (primitive), or simple, spirit, but, as we have seen, each atom is a composition of the simplest. Destiny of an unknown simplest one depends on participation of the atoms known to science.*
There are as many true atoms, as there are primal spirits. A primal spirit wanders through the universe and forms unions. We recognize only unions in the world. Life and feeling of an atom depends on the complexity of the union, which it is in: the more complex the union is, the more complex the activity and feeling of the atom. Here is a rough representation of gradually increasing complexity of an atom’s life.
