A political philosophy (often called "political science" by practitioners who are not averse from verbal trickery) must deal with contemporary realities. If it does not, if it is charged with "ideals," it is merely a variety of romantic fiction, although it may not be recognized as such.
In order to learn true humility (I use this expression to describe the state of mind under discussion), it is good for a person to withdraw from the turmoil of the world (we see that Christ withdrew when the people wanted to proclaim him king as well as when he had to walk the thorny path), for in life either the depressing or the elevating impression is too dominant for a true balance to come about. Here, of course, individuality is very decisive.
