paragraph_text: Philosophy of logic and philosophical logic
  
  Philosophy of logic is the philosophical discipline studying the scope and nature of logic. It examines many presuppositions implicit in logic, like how to define its basic concepts or the metaphysical assumptions associated with them. It is also concerned with how to classify logical systems and considers the ontological commitments they incur. Philosophical logic is one of the areas within the philosophy of logic. It studies the application of logical methods to philosophical problems in fields like metaphysics, ethics, and epistemology. This application usually happens in the form of extended or deviant logical systems.
