Don't know if you are familiar with Jerome Shestack, a human rights activist and attorney, but I ran across this passage in a long article of his and thought of you and CitySquare.
...Sisyphus may turn out to be a more enduring hero than Hercules. For if, as Camus taught, life itself is absurd, then Sisyphus represents the only triumph possible over that absurdity. In his constancy to reach the summit, even with failure preordained, Sisyphus demonstrated that the human spirit is indomitable and that dedication to a higher goal is in itself man's reason for living. So, like Sisyphus, the non-governmental organizations do what they must. The realities of the world may foredoom a great part of the struggle to failure and make most of the effort seem absurd. Yet, the very struggle itself takes on a symbolic meaning, enhancing human dignity. And when all is said and done, there is no other humane course to pursue.
At least from my point of view your work embodies this hope and spirit.
