The paper looks at the phenomenon of subjectivation of a natural object. Subjectivation is the process and result of attributing subjectivity (traits, qualities and functions of a subject) to an object or phenomenon. Analysis of different aspects of the existence of the subject allows the author to identify three specific subject functions that an object or phenomenon should perform in order to be perceived as subjective. The paper describes conditions and mechanisms of subjectivation, its types, variations and developmental stages.
