Understanding the correlation

Understanding the correlation Lets consider a case where we have to understand about something..lets term that x and person as 'y'...and our understanding is always limited to small region...
we begin to find (x intersection y)..
will always gives a smaller view of things ..if was start to understand the supreme the universal set 's'..then we start to understand most of it...and a broader view... (x intersection y) not equals truth
(s union y) =truth..where s is universal set..
where x,y E(belongs to ) s
which in turn post a question how to find s...the answer lies in the true knowledge of y..since y will inherit properties of s...
