The thinking man must oppose all cruel customs no matter how deeply rooted in tradition and surrounded by a halo.

—Albert Schweitzer
apostrophe
Words that are spoken to a person who is absent or imaginary, or to an object or abstract idea. The poem God's World by Edna St. Vincent Millay begins with an apostrophe: "O World, I cannot hold thee close enough!/Thy winds, thy wide grey skies!/Thy mists that roll and rise!"
