Fi – Program function. As an introvert, ESI is primarily oriented at her own directives, system of values, and motivations, for which the external factors are only circumstantial. An ethical introvert possesses in her consciousness an all-encompassing idea about personal and ethical norms, about rules of coexistence, of the need to lead a particular way of life, that, from her point of view, is the only one worthy of a person.
Subjective ethics of relations is ESI's strongest function. She understands, from an earliest age, what is good and what is bad. She is a moralist - and considers it necessary to clearly formulate and firmly observe personal criteria of behavior and moral norms.
Especially important for her are traditions and ethical systems, which, have been accumulated by people throughout centuries. She believes that these traditions, and also the rituals, serve as necessary reference points capable of orienting people in any situation in life. ESI assumes that these traditions must be kept and preserved with great care, never transgressed, and passed on from one generation to another.
