find the facts related to them because their inspection and testing is very difficult and due to this we

difficult its describe on a quantitative basis, if not impossible. So in this mean qualitativeness of social
phenomena it anti to the objectivity, and these arises a very serious problem in search of facts; in the
same way the variability of social phenomena these arises as new problem in search of facts. Because
