Beliefs should be like fluid entities within the mind, some malleable and doubtful, others more viscous and certain. But feeling certain should never be confused with being incontestable. Once a belief is allowed to solidify, it becomes like a shackle on the mind, inhibiting exploration, learning and growth. A fluid mind should never allow a belief to be so hardened that it is beyond rational scrutiny. A fluid mind always invites rational examination upon even its most cherished convictions.
This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of Nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.
I am of the opinion that my life belongs to the whole community and as I live it is my privilege to do for it whatever I can. I want to be thoroughly used up when I die, for the harder I work the more I love. I rejoice in life for its own sake. Life is no brief candle to me; it is a sort of splendid torch which I’ve got a hold of for the moment and I want to make it burn as brightly as possible before handing it on to future generations.
—George Berard Shaw
