Ordinary cruelty is simple stupidity. It comes from the entire want of imagination. It is the result in our days of stereotyped systems, of hard-and-fast rules, of centralisation, of officialism, and of irresponsible authority. Whenever there is centralisation there is stupidity. What is inhuman in modern life is officialism. Authority is as destructive to those who exercise it as it is to those on whom it is exercised.
