What do you mean when you say &#x27;the concept of the world&#x27;?  (honestly asking)<p>Edit: Downvoting this question? Hmm..  I&#x27;ll clarify why I asked.  Wikipedia: &quot;The concept of possible <i>worlds</i> is common in contemporary philosophical discourse but has been disputed.&quot; (Emphasis mine)  It seems dialogue to clarify this concept would have worthwhile meaning for philosophy..
