Metaphilosophy refers to the study of philosophy itself. In simple terms, it is the examination of the methods, assumptions and questions that philosophers make. Another synonym for metaphilosophy could be epistemology, which is the study of knowledge and how it is acquired. Ontology is another term that could be used to describe metaphilosophy. It is a branch of philosophy that focuses on the study of existence, as well as the nature of reality. The study of logic, or logicism, could also be considered a synonym for metaphilosophy since logic is a fundamental tool used in philosophy to reason and evaluate arguments. In essence, metaphilosophy is a philosophical sub-discipline that explores the foundational components of philosophy itself.
