Quotation of King Darius “He who knows not, and knows that he knows not, is simple. Teach him. He who knows not, but knows not that he knows not, is a fool. Shun him. He who knows, but knows not that he knows, is asleep. Wake him up. He who knows, and knows that he knows, is wise. Follow him.”- King Darius of Persia. While reading this few sentences for the first time, I was delighted but latter on when I reflected upon them, a question triggered my mind. ‘What about man who knows not but still pretends that he knows all?’ The answer is; ‘he is a deceiver.’ He deceives others as well as his own self.
