Nature and Art: material and workmanship. There is no beauty unadorned and no excellence that would not become barbaric if it were not supported by artifice: this remedies the evil and improves the good. Nature scarcely ever gives us the very best; for that we must have recourse to art. Without this the best of natural dispositions is uncultured, and half is lacking to any excellence if training is absent. Every one has something unpolished without artificial training, and every kind of excellence needs some polish.
