G.k. Chesterton said this quote

It is the modern literature of the educated, not of the uneducated, which is avowedly and aggressively criminal..The vast mass of humanity, with their vast mass of idle books and idle words, have never doubted and never will doubt that courage is splendid, that fidelity is noble, that distressed ladies should be rescued, and vanquished enemies spared. There are a large number of cultivated persons who doubt these maxims of daily life.
