What is Philosophy: Definition and 336 Discussions

Philosophy (from Greek: φιλοσοφία, philosophia, 'love of wisdom') is the study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language. Such questions are often posed as problems to be studied or resolved. Some sources claim the term was coined by Pythagoras (c. 570 – c. 495 BCE), others dispute this story, arguing that Pythagoreans merely claimed use of a preexisting term. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation.Historically, philosophy encompassed all bodies of knowledge and a practitioner was known as a philosopher. From the time of Ancient Greek philosopher Aristotle to the 19th century, "natural philosophy" encompassed astronomy, medicine, and physics. For example, Newton's 1687 Mathematical Principles of Natural Philosophy later became classified as a book of physics.
In the 19th century, the growth of modern research universities led academic philosophy and other disciplines to professionalize and specialize. Since then, various areas of investigation that were traditionally part of philosophy have become separate academic disciplines, such as psychology, sociology, linguistics, and economics.
Today, major subfields of academic philosophy include metaphysics, which is concerned with the fundamental nature of existence and reality; epistemology, which studies the nature of knowledge and belief; ethics, which is concerned with moral value; and logic, which studies the rules of inference that allow one to derive conclusions from true premises. Other notable subfields include philosophy of science, political philosophy, aesthetics, philosophy of language, and philosophy of mind.

    What are your Thoughts on the Philosophy of Mathematics?

    How do you think of numbers when you're doing math? I particularly feel like sometimes we get to close to acting like computers. We just scan through a list of symbols and compute another list of symbols that makes sense in a certain context. We hardly ever think of things concretely and how...
