Senses: examples: text: [Mr. Haven] objects to our making the Liberator a free, impartial, independent journal, allowing all sides to be fairly heard (as we invariably do) in its columns. He insists on making it (what it has never been) the official organ of the Anti-Slavery Society; […] The American Anti-Slavery Society has an official organ,— […] that paper scrupulously adheres to its one object, excluding from its columns the discussion of those subjects which are so distasteful to Mr. Haven in the Liberator. That paper, therefore, cannot justly be charged with "being its own worst enemy."
