St. Francis anticipated all that is most liberal and sympathetic in the modern mood; the love of nature; the love of animals; the sense of social compassion; the sense of the spiritual dangers of prosperity and even of property. All those things that nobody understood before Wordsworth were familiar to St. Francis. All those things that were first discovered by Tolstoy could have been taken for granted by St Francis.
–G. K. Chesterton, St. Francis of Assisi
