Art itself is essentially ethical; because every true work of art must have a beauty or grandeur of some kind, and beauty and grandeur cannot be comprehended by the beholder except through the moral sentiment.

The mind judges what the eye reports to it; therefore, whatever elevates the moral sentiment to the contemplation of beauty and grandeur is in itself ethical.
