Reason

==Etymology and related words==
In the [[English language]] and other modern [[Languages of Europe|European languages]], "reason", and related words, represent words which have always been used to translate Latin and classical Greek terms in their philosophical sense.
* The original [[Greek language|Greek]] term was {{lang|grc|"λόγος"}} {{transliteration|grc|[[wikt:logos#Greek|logos]]}}, the root of the modern English word "[[logic]]" but also a word that could mean for example "speech" or "explanation" or an "account" (of money handled).<ref>{{multiref2

* As a philosophical term {{transliteration|grc|logos}} was translated in its non-linguistic senses in [[Latin]] as {{lang|la|[[wikt:ratio#Latin|ratio]]}}. This was originally not just a translation used for philosophy, but was also commonly a translation for {{transliteration|grc|logos}} in the sense of an account of money.<ref>{{Citation|chapter-url=https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0059%3Aentry%3Dratio|chapter=ratio|first1=Charlton |last1=Lewis|first2= Charles |last2=Short|title=A Latin Dictionary}}</ref>
* [[French language|French]] {{lang|fr|[[wikt:raison|raison]]}} is derived directly from Latin, and this is the direct source of the English word "reason".<ref name=mw/>

The earliest major philosophers to publish in English, such as [[Francis Bacon]], [[Thomas Hobbes]], and [[John Locke]] also routinely wrote in Latin and French, and compared their terms to Greek, treating the words "{{transliteration|grc|logos}}", "{{lang|la|ratio}}", "{{lang|fr|raison}}" and "reason" as interchangeable. The meaning of the word "reason" in senses such as "human reason" also overlaps to a large extent with "[[rationality]]" and the adjective of "reason" in philosophical contexts is normally "[[Rationality|rational]]", rather than "reasoned" or "reasonable".<ref>{{multiref2
