The love of virtue, and every other noble feeling, is not communicated by reasoning, but caught by inspiration or sympathy from those who already have it; and its nurse and foster-mother is Admiration. We acquire it from those whom we love and reverence, especially from those whom we earliest love and reverence; from our ideal of those, whether in past or in present times, whose lives and characters have been the mirror of all noble qualities; and lastly, from those who, as poets or artists, can clothe those feelings in the most beautiful forms, and breathe them into us through our imagination and our sensations.
[John Stuart Mill, Notes on Plato's Gorgias]
