This question has been put to me by a gentleman whom I do not know. I do not even know whether he is a friend of mine or a supporter of Judge Douglas in this contest, nor does that make any difference. His question is a proper one. Lest I should forget it, I will give you my answer before proceeding with the line of argument I have marked out for this discussion.
The difference between the Republican and the Democratic parties on the leading issues of this contest, as I understand it, is that the former consider slavery a moral, social and political wrong, while the latter do not consider it either a moral, a social or a political wrong; and the action of each, as respects the growth of the country and the expansion of our population, is squared to meet these views. I will not affirm that the Democratic party consider slavery morally, socially and politically right, though their tendency to that view has, in my opinion, been constant and unmistakable for the past five years. I prefer to take, as the accepted maxim of the party, the idea put forth by Judge Douglas, that he don't care whether slavery is voted down or voted up." I am quite willing to believe that many Democrats would prefer that slavery should be always voted down, and I know that some prefer that it be always voted up"; but I have a right to insist that their action, especially if it be their constant action, shall determine their ideas and preferences on this subject. Every measure of the Democratic party of late years, bearing directly or indirectly on the slavery question, has corresponded with this notion of utter indifference whether slavery or freedom shall outrun in the race of empire across to the Pacific--every measure, I say, up to the Dred Scott decision, where, it seems to me, the idea is boldly suggested that slavery is better than freedom. The Republican party, on the contrary, hold that this government was instituted to secure the blessings of freedom, and that slavery is an unqualified evil to the negro, to the white man, to the soil, and to the State. Regarding it as an evil, they will not molest it in the States where it exists, they will not overlook the constitutional guards which our fathers placed around it; they will do nothing that can give proper offence to those who hold slaves by legal sanction; but they will use every constitutional method to prevent the evil from becoming larger and involving more negroes, more white men, more soil, and more States in its deplorable consequences. They will, if possible, place it where the public mind shall rest in the belief that it is in course of ultimate peaceable extinction in God's own good time. And to this end they will, if possible, restore the government to the policy of the fathers, the policy of preserving the new Territories from the baneful influence of human bondage, as the Northwestern Territories were sought to be preserved by the Ordinance of 1787, and the Compromise Act of 1820. They will oppose, in all its length and breadth, the modern Democratic idea, that slavery is as good as freedom, and ought to have room for expansion all over the continent, if people can be found to carry it. All, or nearly all, of Judge Douglas's arguments are logical, if you admit that slavery is as good and as right as freedom, and not one of them is worth a rush if you deny it. This is the difference, as I understand it, between the Republican and Democratic parties.
My friends, I have endeavored to show you the logical consequences of the Dred Scott decision, which holds that the people of a Territory cannot prevent the establishment of slavery in their midst. I have stated what cannot be gainsaid, that the grounds upon which this decision is made are equally applicable to the free States as to the free Territories, and that the peculiar reasons put forth by Judge Douglas for indorsing this decision commit him, in advance, to the next decision and to all other decisions corning from the same source. And when, by all these means, you have succeeded in dehumanizing the negro; when you have put him down and made it impossible for him to be but as the beasts of the field; when you have extinguished his soul in this world and placed him where the ray of hope is blown out as in the darkness of the damned, are you quite sure that the demon you have roused will not turn and rend you? What constitutes the bulwark of our own liberty and independence? It is not our frowning battlements, our bristling sea coasts, our army and our navy.
