All empty souls tend to extreme opinion. It is only in those who have built up a rich world of memories and habits of thought that extreme opinions affront the sense of probability. Propositions, for instance, which set all the truth upon one side can only enter rich minds to dislocate and strain, if they can enter at all, and sooner or later the mind expels them by instinct.
William Butler YeatsAnd pluck till time and times are done the silver apples of the moon the golden apples of the sun.
William Butler YeatsO what fine thought we had because we thought that the worst rogues and rascals had died out.
William Butler Yeats
