The everyday understanding of common sense derives from philosophical discussion involving several European languages. Related terms in other languages include Latin sensus communis , Greek κοινὴ αἴσθησις ( koinē aísthēsis ), and French bon sens , but these are not straightforward translations in all contexts. Similarly in English, there are different shades of meaning, implying more or less education and wisdom: "good sense" is sometimes seen as equivalent to "common sense", and sometimes not. 
"Common sense" has at least two specifically philosophical meanings. One is a capability of the animal soul (Greek psukhē ) proposed by Aristotle , which enables different individual senses to collectively perceive the characteristics of physical things such as movement and size, which all physical things have in different combinations, allowing people and other animals to distinguish and identify physical things. This common sense is distinct from basic sensory perception and from human rational thinking, but cooperates with both. The second special use of the term is Roman-influenced and is used for the natural human sensitivity for other humans and the community.  Just like the everyday meaning, both of these refer to a type of basic awareness and ability to judge that most people are expected to share naturally, even if they can not explain why.
