Intellectual Diversity in the University

How far we understand and respect the intellectual diversity in the university?
How do we assess the quality and the diversity of intellect in university?
Do we have enough experts to do the assessment? Or we just follow outsiders criteria without understand them.
May be at our level we should use our criteria at the time being and promote the intellectual diversity among us in the process of meeting the world standard. Without start we cannot move.
