"I am I" as a dogmatic judgment
The reality of the "I" as the beginning and condition of the unity of personal being is considering at the article. First of all, it is about the "I" in the human dimension. Then the possibility to think the reality of the "I" as applied to the hypostatic being of God is justified. At the same time, it is shown that, in essence, it is the reverse order: "I am I" is a judgment conditioned by the ontology of the Persons of the Holy Trinity. The justification is given that the humans personality also begins with the reality of the "I" due to the assimilation of the creation and incarnation dogmatas.
