I'm done with great things and big things, great intentions and big success, and I am for those tiny invisible molecular moral forces that work from individual to individual, creeping through the crannies of the world like so many rootlets, or like the capillary oozing of water. Yet which, if you give them time, will rend the hardest monuments of our pride.
