https://de.wikipedia.org/wiki/Deduktion Deduction, derived from the Latin term "deductio," refers to the process of drawing logically necessary conclusions from given premises. A conclusion is considered deductively valid if it logically follows from the premises, meaning the truth of the premises guarantees the truth of the conclusion. Alfred Tarski highlights that logical consequence, a key aspect of deduction, is necessary, formal, and a priori recognizable. Deductive reasoning is studied in various fields, including logic, psychology, and cognitive sciences, each emphasizing different aspects of the process.
