ABSTRACT
Philosophy of logic deals with issues about logic that are broadly philosophical, especially metaphysical (about reality) or epistemological (about how we know). Here are examples: Are there abstract entities, and does logic presuppose them? Is logic the key to understanding the structure of reality? How do we know logical laws – are they empirical or true by convention? What is truth, and how do different views on truth affect logic? What is the scope of logic?
