Rosetti makes the remark somewhere, bitterly but with great truth, that the worst moment for the atheist is when he is really thankful and has nobody to thank. The converse of this proposition is also true; and it is certain that this gratitude produced, in such men as we are here considering, the most joyful moments that have been known to man. The great painter boasted that he mixed all his colors with brains, and the great saint may be said to mix all his thoughts with thanks.

-St. Francis of Assisi (1923)
