..."that is the highest of the arts"

It is something to be able to paint a particular picture, or to carve a statue, and so to make a few objects beautiful, but it is more glorious to carve and paint the very atmosphere and medium through which we look, which morally we can do. To affect the quality of the day, that is the highest of arts. We are tasked to make our lives, even in its details, worthy of the contemplation of our most elevated and critical hour.  Henry David Thoreau, Walden
