It is important for one who is so fond as you are of making distinctions, to see to it that they are just and valid. It is of immense moment that one who builds so much on words should rest his structure on the solid foundation of a correct and exact conception of them. Words are often things, and sometimes things of tremendous consequence, and none more so than those which enter into the grounding principles, of politics. No theoretical error but works practical mischief. No one should be more aware of this than he who undertakes the 'diffusion of political knowledge' among the people of this country. The false notions on sovereignty and sovereign rights which you have put forth, are precisely the ones to take root and bear evil fruit among the least instructed and least thoughtful, the most passionate and unscrupulous of our people. In short, it is among the lowest and worst elements of our social life--among the sort of persons that swelled the majorities in the Sixth Ward of Sodom--that you win find your most numerous disciples and readiest coadjutors in your bad work of opposing the constituted authorities of the state; and this at a time when every good man and true patriot should think much more of duties than of rights, and be more willing to forego personal rights for his country's good, than by factious assertion of them to weaken the arm of public power struggling to save the national existence. I shall go on in another letter to consider your utterances on the distinction between the Government and the Administration, and your special pleas for hostility to the constituted authorities.

Dear Sir: I now proceed to consider your letter to Mr. Crosby, which I cannot help regarding as fitted to excite sentiments of mortification as well as grief in the minds of all intelligent men and good patriots who in time past have known and honored you. What such as have not known or cared for you will be apt to think, I shall not undertake to say. One of Mr. Crosby's questions was this: 'What appears to you the sufficient reason for a Christian citizen to ally himself with others for the extreme and radical purpose of undermining and paralyzing the power of the Government at a crisis when unanimity of support is plainly essential not only to the welfare but to the very life of the nation?'
