Philosophical methods include questioning, critical discussion, rational argument and systematic presentation.[7][8] Classic philosophical questions include: Is it possible to know anything and to prove it?[9][10][11] What is most real? However, philosophers might also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust (if you can get away with it)?[12] Do humans have free will?[13] Historically, "philosophy" encompassed any body of knowledge.[14] From the time of Ancient Greek philosopher Aristotle to the 19th century, "natural philosophy" encompassed astronomy, medicine and physics.[15] 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.[16][17] In the modern era, some investigations that were traditionally part of philosophy became separate academic disciplines, including psychology, sociology, linguistics and economics. Other investigations closely related to art, science, politics, or other pursuits remained part of philosophy. For example, is beauty objective or subjective?[18][19] Are there many scientific methods or just one?[20] Is political utopia a hopeful dream or hopeless fantasy?[21][22][23] Major sub-fields of academic philosophy include metaphysics ("concerned with the fundamental nature of reality and being"),[24] epistemology (about the "nature and grounds of knowledge [and]...its limits and validity" [25]), ethics, aesthetics, political philosophy, logic, philosophy of science and the history of Western philosophy. Since the 20th century professional philosophers contribute to society primarily as professors, researchers and writers. However, many of those who study philosophy in undergraduate or graduate programs contribute in the fields of law, journalism, politics, religion, science, business and various art and entertainment activities.[26]
