Logic is the mental function of the human psyche, processing information and making decisions objectively, impartially. In socionics, the general function of logic is divided into business/pragmatic logic (P), meaning enterprise, labor, calculation of benefits, and structural logic (L), symbolizing the classification, schematism, organization.

On an intellectual level, the L-dimension means the construction of schemes, structures, and classifications. This kind of logic pursues the goal of the correctness and proportionality of proportions instead of efficiency and profitability.〔中略〕Thinking in category L, a person compares one object with another according to various criteria and places it in the corresponding cell of the classification table.

Psychologically, the person in the L-state is distinguished by coolness and indifference. In this state, there are no feelings and subjective predilections. Figuratively, this state can be likened to a block of ice or the geometric regularity of a crystal of some mineral. This is the least psychological state, since it has absolutely no soul or human warmth, but on the other hand, it is the most balanced and stable.

State L leads to an informal role in the team: that of a systematizer or an expert. It is expressed in making objective, disinterested judgments on any issue of life.〔中略〕The second side of the L-role is the judge. People turn to such a person for his maximum objectivity when it is needed to soberly judge this or that controversial case.

The correctness of the system is determined by its internal logical consistency; she easily modifies the formal framework of the system.〔中略〕She easily sees the possibilities of systems, formal models and concepts. She gives an objective, often impartial assessment of their potential. She is able to tie specific details in with the whole.

SEI has trouble perceiving chaotic information. It confuses her and spoils the mood. She likes it when specific phenomena are linked with general patterns. Her mood rises from the awareness that she is needed and indispensable. She likes to be compatible with the place assigned to her. She is motivated when somebody sets a clear goal before her and explains the direction she needs to go in to reach it. She will find ways of achieving goals herself and doesn’t need “bare” facts, instructions, or explanations. Most importantly, when she likes the system and it evokes emotions in her, then she becomes goal- oriented and organized.
