In societies with fewer opportunities for amusement, it was also easier to tell a mere wish from a real desire. If, in order to hear some music, a man has to wait for six months and then walk twenty miles, it is easy to tell whether the words, "I should like to hear some music," mean what they appear to mean, or merely, "At this moment I should like to forget myself." When all he has to do is press a switch, it is more difficult. He may easily come to believe that wishes can come true.
