No human face is exactly the same in its lines on each side, no leaf perfect in its lobes, no branch in its symmetry. All admit irregularity as they imply change; and to banish imperfection is to destroy expression, to check exertion, to paralyze vitality. All things are literally better, lovelier, and more beloved for the imperfections which have been divinely appointed, that the law of human life may be Effort, and the law of human judgment, Mercy.
John RuskinThe repose necessary to all beauty is repose, not of inanition, nor of luxury, nor of irresolution, but the repose of magnificent energy and being; in action, the calmness of trust and determination; in rest, the consciousness of duty accomplished and of victory won; and this repose and this felicity can take place as well in the midst of trial and tempest, as beside the waters of comfort.
John Ruskin
