 In his most famous speech, “What To the Slave Is The Fourth of July?”, he detailed what would come to be regarded as his signature positions, such as the view that slavery was unconstitutional and contrary to natural law, that blacks were self-evidently human and entitled to natural rights, and that slavery was contrary to the U.S. Constitution, American Republicanism, and Christian doctrine. He also began to defend violent resistance to slavery. Douglass’s second autobiography, My Bondage and My Freedom, reflected these changes, and his expanding intellectual independence (FDAB; for a stand-alone edition, see the 1987 version edited by Andrews).
