What is Common Sense ?



We all have sometimes asked to use common sense from someone but have we really thought about it that what is common sense and how do we explain to someone as we do not have any criteria to judge it but we do expect from others to use it.

Have tried to search about it at many places and also asked few people about its real meaning but did not get satisfactory definition of it then finally I searched it in Wikipedia and it gives the definition of common sense as a basic ability to perceive, understand and judge things which are shared by nearly all people and can be become a reasonable expectation of nearly all people without having need of any debate on the same.

In Latin it is called Senus Communis, Greek it is called as Koine aesthesis, and in French bon sens.
Amazingly Wikipedia also shows that how to develop common sense with steps including images ;)
So if someone feels that he does not have common sense so it is never too late to develop it as so much information is available in net which will help the person to develop it.
