Philosophy which literally means “love of wisdom“, is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing fundamental questions (such as mysticism, myth, or religion) by its critical, generally systematic approach and its reliance on rational argument. It involves logical analysis of language and clarification of the meaning of words and concepts.
Other investigations closely related to art, science, politics, or other pursuits remained part of philosophy. For example, is beauty objective or subjective? Are there many scientific methods or just one? Is political utopia a hopeful dream or hopeless fantasy? Major sub-fields of academic philosophy include metaphysics (“concerned with the fundamental nature of reality and being”), epistemology (about the “nature and grounds of knowledge [and]…its limits and validity”), ethics, aesthetics, political philosophy, logic and philosophy of science.
A philosopher was someone who lived according to a certain way of life, focusing on resolving existential questions about the human condition, and not someone who discourses upon theories or comments upon authors.
