It is a rational and critical inquiry that reflects on its own methods and assumptions. Historically, many of the individual [[science]]s, such as [[physics]] and [[psychology]], formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the [[history of philosophy]] include [[Western philosophy|Western]], [[Islamic philosophy|Arabic–Persian]], [[Indian philosophy|Indian]], and [[Chinese philosophy]]. Western philosophy originated in [[Ancient Greece]] and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and [[revelation]]. Indian philosophy combines the [[Spirituality|spiritual]] problem of how to reach [[Enlightenment in Buddhism|enlightenment]] with the exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues in relation to right social conduct, government, and [[self-cultivation]]. Major branches of philosophy are [[epistemology]], [[ethics]], [[logic]], and [[metaphysics]]. Epistemology studies what knowledge is and how to acquire it. Ethics investigates moral principles and what constitutes right conduct. Logic is the study of [[Logical reasoning|correct reasoning]] and explores how good [[argument]]s can be distinguished from bad ones. Metaphysics examines the most general features of [[reality]], existence, [[Object (philosophy)|objects]], and [[Property (philosophy)|properties]]. Other subfields are [[aesthetics]], [[philosophy of language]], [[philosophy of mind]], [[philosophy of religion]], [[philosophy of science]], [[philosophy of mathematics]], [[philosophy of history]], and [[political philosophy]]. Within each branch, there are competing [[schools of philosophy]] that promote different principles, theories, or methods. Philosophers use a great variety of methods to arrive at philosophical knowledge. They include [[conceptual analysis]], reliance on [[common sense]] and [[intuition]]s, use of [[thought experiments]], analysis of [[ordinary language]], [[Phenomenology (philosophy)|description of experience]], and [[Socratic questioning|critical questioning]]. Philosophy is related to many other fields, including the sciences, [[mathematics]], [[business]], [[law]], and [[journalism]]. It provides an [[interdisciplinary]] perspective and studies the scope and fundamental concepts of these fields. It also investigates their methods and ethical implications. {{toclimit|3}} == Etymology == The word ''philosophy'' comes from the [[Ancient Greek]] words {{lang|grc|φίλος}} ({{transl|grc|philos}}) {{gloss|love}} and {{lang|grc|σοφία}} ({{transl|grc|sophia}}) {{gloss|wisdom}}.<ref>{{multiref |1={{harvnb|Hoad|1993|p=350}} |2={{harvnb|Simpson|2002|loc=Philosophy}} |3={{harvnb|Jacobs|2022|p=[https://books.google.com/books?id=Kw9sEAAAQBAJ&pg=PA23 23]}} }}</ref>{{efn|The Ancient Greek ''philosophos'' ('philosopher') was itself possibly borrowed from the [[Ancient Egyptian]] term ''mer-rekh'' (''mr-rḫ'') meaning 'lover of wisdom'.<ref>{{multiref |1={{harvnb|Herbjørnsrud|2021|p=123}} |2={{harvnb|Herbjørnsrud|2023|p=X}} }}</ref>}} Some sources say that the term was coined by the [[pre-Socratic]] philosopher [[Pythagoras]], but this is not certain.<ref>{{multiref |1={{harvnb|Bottin|1993|p=[https://books.google.com/books?id=FJ7UBP_jYeMC&pg=PA151 151]}} |2={{harvnb|Jaroszyński|2018|p=[https://books.google.com/books?id=fsZKDwAAQBAJ&pg=PA12 12]}} }}</ref> [[File:Doctor Zirkel follows Newton's famous steps under the fabled Wellcome V0011942.jpg|alt=Wood engraving of Isaac Newton under an apple tree|thumb|left|upright=0.75|Physics was originally part of philosophy, like [[Isaac Newton]]'s observation of how [[Isaac Newton's apple tree|gravity affects falling apples]].]] The word entered the English language primarily from [[Old French]] and [[Anglo-Norman language|Anglo-Norman]] starting around 1175 CE.

It is sometimes understood as a metadiscipline that clarifies their nature and limits. It does this by critically examining their basic concepts, background assumptions, and methods. In this regard, it plays a key role in providing an [[interdisciplinary]] perspective. It bridges the gap between different disciplines by analyzing which concepts and problems they have in common. It shows how they overlap while also delimiting their scope.{{sfn|Audi|2006|pp=332–337}} Historically, most of the individual sciences originated from philosophy.<ref>{{multiref |1={{harvnb|Tuomela|1985|p=[https://books.google.com/books?id=2Hg9rKafnHsC&pg=PA1 1]}} |2={{harvnb|Grant|2007|p=[https://books.google.com/books?id=-g26ckhZ21wC&pg=PA303 303]}} }}</ref> The influence of philosophy is felt in several fields that require difficult practical decisions.
