Bilanzlogik

Bilanzlogik is a term used in German-language discussions to describe several related ideas about how systems maintain balance or equivalence across logical transformations. The term combines bilanz (balance, accounting) with logik (logic), and is used in different contexts rather than to denote a single, standardized theory.

In philosophy and logic, Bilanzlogik denotes a family of formalisms that treat balance as a primitive notion alongside truth. These systems introduce balance operators that express conservation of information or symmetrical treatment of opposing propositions. They are related to paraconsistent and dialethic logics, as they accommodate inconsistent input while seeking to preserve an overall balance or coherence.

In economics and accounting, Bilanzlogik appears in discussions about the logical structure of balance sheets, assets and liabilities, and how changes in one side affect the other, emphasizing invariants such as the equality of debits and credits.

Formal methods include extending classical logic with balance axioms, and rule schemas that govern how balance is maintained during deduction or calculation. Critics note that the lack of a single formal standard makes Bilanzlogik more of an umbrella term than a precise theory; supporters argue that it highlights important principles of conservation, symmetry and reconciliation across domains.

Applications range from pedagogy in accounting to design of decision-support tools and portfolio balancing in finance, and to theoretical investigations of balance as a logical primitive. See also paraconsistent logic, conservation laws, and decision theory.
