To hope is to gamble. It's to bet on the future, on your desires, on the possibility that an open heart and uncertainty are better than gloom and safety. To hope is dangerous, and yet it is the opposite of fear, for to live is to risk. I say all this to you because hope is not like a lottery ticket you can sit on the sofa and clutch, feeling lucky. I say this because hope is an ax you break down doors with in an emergency; because hope should shove you out the door, because it will take everything you have to steer the future away from endless war, from annihilation of the earth's treasures and the grinding down of the poor and marginal. Hope just means another world might be possible, not promised, not guaranteed. Hope calls for action; action is impossible without hope.
