"The slightest living thing answers a deeper need than all the works of man because it is transitory. It has an evanescence of life, or growth, or change: it passes, as we do, from one stage to another, from darkness to darkness, into a distance where we, too, vanish out of sight. A work of art is static; and its value and its weakness lie in being so: but the tuft of grass and the clouds above it belong to our own traveling brotherhood."
