The sense of that quotation condensed is this: that this slavery element is a durable element of discord among us, and that we shall probably not have perfect peace in this country with it until it either masters the free principle in our government, or is so far mastered by the free principle as for the public mind to rest in the belief that it is going to its end. This sentiment, which I now express in this way, was, at no great distance of time, perhaps in different language, and in connection with some collateral ideas, expressed by Governor Seward. Judge Douglas has been so much annoyed by the expression of that sentiment that he has constantly, I believe, in almost all his speeches since it was uttered, been referring to it. I find he alluded to it in his speech here, as well as in the copyright essay. I do not now enter upon this for the purpose of making an elaborate argument to show that we were right in the expression of that sentiment. In other words, I shall not stop to say all that might properly be said upon this point, but I only ask your attention to it for the purpose of making one or two points upon it.
If you will read the copyright essay, you will discover that judge Douglas himself says a controversy between the American Colonies and the Government of Great Britain began on the slavery question in 1699, and continued from that time until the Revolution; and, while he did not say so, we all know that it has continued with more or less violence ever since the Revolution.
Then we need not appeal to history, to the declarations of the framers of the government, but we know from judge Douglas himself that slavery began to be an element of discord among the white people of this country as far back as 1699, or one hundred and sixty years ago, or five generations of men,—counting thirty years to a generation. Now, it would seem to me that it might have occurred to Judge Douglas, or anybody who had turned his attention to these facts, that there was something in the nature of that thing, slavery, somewhat durable for mischief and discord.
