symbolic logic
Mathematical deduction system
Symbolic logic is a branch of logic that uses symbols, formulas, and precise notation to represent logical relationships and arguments, rather than ordinary language.
It provides rigorous methods for analyzing validity of reasoning through formal systems like propositional and predicate calculus.
The approach strips away the ambiguities of natural language, allowing logical structures to be manipulated almost mathematically.
The philosophy department requires symbolic logic before students can take advanced courses.
