Philosophy of logic
From Wikipedia, the free encyclopedia
Philosophy of logic is the branch of philosophy that is concerned with the nature and justification of systems of logic. Some fundamental questions with which it is concerned are:
- Is there only one "true" logic, or are many logics equally correct?
- Is it possible to have genuine disagreements about whether a logical principle (such as the law of excluded middle) is correct?
- What makes an expression a logical constant?
- What are the proper accounts of logical consequence, quantification, and other logical concepts?
- What is the scope of logic (e.g., does it encompass mathematics)?
- Is second-order logic really logic?
- Is logic a matter of convention?
- Is logic empirical?
- What is the nature of logical necessity?
Philosophy of logic is often confused with philosophical logic, which is the application of formal logical techniques to philosophical problems. Several philosophers have made important contributions to both fields.
There is some overlap between philosophy of logic, philosophical logic, philosophy of language, epistemology, and metaphysics.
