Endogenous and Exogenous ( Inside could be Outside and Outside could be Inside) Relative ! Russell's Paradox

If I draw the Logic from Russell's Paradox, it would state that If A set lies outside the Set B, then it would like inside the Set B. The relevance is that "Inside/Internal and Outside/External" are not so separable and relatively existing ! 

What lies outside/external could actually be inside /internal and vice versa in real world as well..
