Bulwark

"What constitutes the bulwark of our own liberty and independence? It is not our frowning battlements, our bristling sea coasts, the guns of our war steamers, or the strength our gallant and disciplined army? These are not our reliance against a resumption of tyranny in our fair land. All of those may be turned against our liberties, without making us weaker or stronger for the struggle. Our reliance is in the love of liberty which God has planted in our bosoms. Our defense is in the preservation of the spirit which prizes liberty as the heritage of all men, in all lands, everywhere. Destroy this spirit, and you have planted the seeds of despotism around your own doors. Familiarize yourselves with the chains of bondage and you are preparing your own limbs to wear them. Accustomed to trample on the rights of those around you, you have lost the genius of your own independence, and become the fit subjects of the first cunning tyrant who rises."
--Abraham Lincoln,
Speech at Edwardsville, Illinois (September 11, 1858)
