“True variety is in that plenitude of real and unexpected elements, in the branch charged with blue flowers thrusting itself, against all expectations, from the springtime hedge which seems already too full, while the purely formal imitation of variety ... is but void and uniformity, that is, that which is most opposed to variety....”
—Marcel Proust (1871–1922)
“I never yet knew the sun to be knocked down and rolled through a mud-puddle; he comes out honor-bright from behind every storm. Let us then take sides with the sun, seeing we have so much leisure.”
—Henry David Thoreau (1817–1862)
