 What makes nature different is that it presupposes not only that not all customs and ways are equal, but also that one can "find one's bearings in the cosmos" "on the basis of inquiry" (not for example on the basis of traditions or religion).To put this "discovery or invention" into the traditional terminology, what is "by nature" is contrasted to what is "by convention".The concept of nature taken this far remains a strong tradition in modern western thinking.
