When a sixth of the population of a nation which has undertaken to be the refuge of liberty are slaves, and a whole country [Mexico] is unjustly overrun and conquered by a foreign army, and subjected to military law, I think that it is not too soon for honest men to rebel and revolutionize. What makes this duty the more urgent is the fact that the country so overrun is not our own, but ours is the invading army.
