It has become a common feeling, I believe, as we have watched our heroes falling over the years, that our own small stone of activism, which might not seem to measure up to the rugged boulders of heroism we have so admired, is a paltry offering toward the building of an edifice of hope. Many who believe this choose to withhold their offerings out of shame. This is the tragedy of the world. For we can do nothing substantial toward changing our course on the planet, a destructive one, without rousing ourselves, individual by individual, and bringing our small, imperfect stones to the pile.
