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.

There is another point I desire to make in regard to this matter, before
I leave it. From the adoption of the Constitution down to 1820 is the
precise period of our history when we had comparative peace upon this
question,--the precise period of time when we came nearer to having peace
about it than any other time of that entire one hundred and sixty years
in which he says it began, or of the eighty years of our own Constitution.
Then it would be worth our while to stop and examine into the probable
reason of our coming nearer to having peace then than at any other time.
This was the precise period of time in which our fathers adopted, and
during which they followed, a policy restricting the spread of slavery,
and the whole Union was acquiescing in it. The whole country looked
forward to the ultimate extinction of the institution. It was when a
policy had been adopted, and was prevailing, which led all just and
right-minded men to suppose that slavery was gradually coming to an end,
and that they might be quiet about it, watching it as it expired. I think
Judge Douglas might have perceived that too; and whether he did or not, it
is worth the attention of fair-minded men, here and elsewhere, to consider
whether that is not the truth of the case. If he had looked at these two
facts,--that this matter has been an element of discord for one hundred
and sixty years among this people, and that the only comparative peace we
have had about it was when that policy prevailed in this government which
he now wars upon, he might then, perhaps, have been brought to a more just
appreciation of what I said fifteen months ago,--that "a house divided
against itself cannot stand. I believe that this government cannot endure
permanently, half slave and half free. I do not expect the house to fall,
I do not expect the Union to dissolve; but I do expect it will cease to
be divided. It will become all one thing, or all the other. Either the
opponents of slavery will arrest the further spread of it, and place it
where the public mind will rest in the belief that it is in the course of
ultimate extinction, or its advocates will push it forward until
