Advice to Arthur
“The best thing for disturbances of the spirit,” replied Merlyn, beginning to puff and blow, “is to learn. That is the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night, listening to the disorder of your veins, you may miss your only love and lose your moneys to a monster, you may see the world around you devastated by evil lunatics, or know your honour trampled in the sewers of base minds. There is only one thing for it then – to learn. Learn why the world wags and what wags it. That is the only thing the poor mind can never exhaust, and never dream of regretting. Learning is the thing for you.”
