I am done with great things and big things

I am done with great things
And big things, great institutions
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.
