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 YeatsA line will take us hours maybe; / Yet if it does not seem a moment's thought, / Our stitching and unstitching has been naught... Better go down upon your marrow-bones / And scrub a kitchen pavement, or break stones... For to articulate sweet sounds together / Is to work harder than all these, and yet / Be thought an idler by the noisy set.
William Butler YeatsOne should say before sleeping: I have lived many lives. I have been a slave and a prince. Many a beloved has sat upon my knee and I have sat upon the knees of many a beloved. Everything that has been shall be again.
