It is eminently a weariable faculty, eminently delicate, and incapable of bearing fatigue; so that if we give it too many objects at a time to employ itself upon, or very grand ones for a long time together, it fails under the effort, becomes jaded, exactly as the limbs do by bodily fatigue, and incapable of answering any farther appeal till it has had rest.
John RuskinWherever the human mind is healthy and vigorous in all its proportions, great in imagination and emotion no less than in intellect, and not overborne by an undue or hardened pre-eminence of the mere reasoning faculties, there the grotesque will exist in full energy.
John Ruskin
