Conclusion

So, now we understand why ontology is a formalized, shared conceptualization of a subject area, namely a set of objects and relationships of the subject area, common to certain roles associated with this subject area (https://en.wikipedia.org/wiki/Ontology_(information_science)).

We have discussed how at the most general level thinking forms ontologies: it identifies objects, names them, distinguishes individuals from categories, relates objects to categories, and creates new categories based on the needs of different roles.

And all of this happens within the framework of modeling, which forms the basis of any thinking, whether of people, computers, or any other agents where thinking can be detected.
