"We plant a tree that won't be big enough to climb until we're too old to climb trees, we write constitutions to protect the rights of people who won't be born for another hundred years and may not be worth the trouble anyway, and we try to take care of our sick, though we all suffer from a disease for which there is no cure and no hope for one. We will not last and we know we will not - and still we write, carve, build, paint and plant to last. We are, it seems to me, very, very brave."
