Begriffsschrift Und Andere Aufsätze by Gottlob Frege

A collection of influential essays developing a rigorous, symbolic foundation for logic and mathematics: it introduces a formal predicate calculus to analyze functions and arguments, argues for arithmetic’s reduction to logical principles, defends the objectivity of logical laws against psychologism, and articulates seminal distinctions such as sense versus reference that clarify meaning and reference in language; together the pieces lay out technical systems and philosophical arguments that reshaped the study of logic, language, and the foundations of mathematics.
