Writer: In the world of shadows. And if there is no source of light, then – generally in darkness.

Consultant: The most striking thing is that as soon as you have gathered an understanding of the subject from the three shadows, you can now change the lighting at any angle – you will still recognize this particular object in any shadow.

Writer: It's like a teacher who knows his topic well.. He can answer the question not with a quote from a textbook, but the way the answer is refracted in a specific situation, taking into account how old the student is in front of him and what are his abilities to perceive information.

Engineer: By the way, about perception. But an object, not a scientific object, but the one that is drawn on the board – after all, it can smell, make sounds, taste different, have different temperatures from different sides. Imagine how our brain, simultaneously collecting information from different receptors, collects a holistic multidimensional object and keeps it in focus and dynamics of change.

Writer: It seems to me that the person himself for another person is the most complex object, which is somehow collected in pieces in the head and then lives there. And every time you interact with this person, the projections of the whole are rechecked, something is added or removed, the model of this person is refined in the head.

Consultant: This is despite the fact that, as the Engineer says, we do not see the person directly. There are photons flying to the retina of the eye, there are sound waves, there are molecules of smell, the warmth of touch, and all this is combined with the image of this person in memory, which is refined with each new portion of information. Returning to our previous conversation: there is a person somewhere in the external environment, and in our head we see him only as a float on the surface of our consciousness… People, like fish in the ocean of life, touch our sensory hooks, fishing lines are pulled, and we sit on the shore of our consciousness and talk with floats :(

Writer: Have you ever wondered what “consciousness” is? Tell me, how many fingers do you see?

Engineer: Two.

Consultant: I do confirm, two. But what's the catch? It is the usual test for the presence of consciousness. When a person falls unconscious, after he is brought to his senses, he is asked about the number of fingers to make sure that it is adequate.

Writer: It turns out that you know that there are two of them. And you know. And I know. And we have “co-knowledge” or “co-science”! Latin roots confirm the same meaning: consciousness – shared knowledge. An interesting lesson is to take a close look at English words starting with “co-” and “con-”.

Engineer: It turns out that consciousness is somehow connected with language? We are with you in the Russian mind, the British in the English mind, the Chinese in the Chinese. And when we learn other languages, do we expand our consciousness?

Consultant: Square, triangle, circle…

Engineer: I disagree. “A chair” is “a chair” everywhere despite the wording of the language.

Writer: And what about different associations and connotations?

Engineer: It turns out that there is a certain capacity of the language, and it depends not only on the number of words, but also on the number of connections between them. Just like with human neurons! According to the latest data that I heard, there are about eighty billion of them, and there are more neural connections that these neurons form among themselves than there are stars in the sky! Some incredible numbers.
