The End of History?

In commenting on Hegel, Collingwood argues:

History must end with the present, because nothing else has happened. But this does not mean glorifying the present or thinking that future progress is impossible. It only means recognizing the present as a fact and realizing that we do not know what future progress will be. As Hegel put it, the future is an object not of knowledge butof hopes and fears; and hopes and fears are not history.

Of course, another way of looking at historical thought is that the job of the historian is to make clear the teleological idea that the end of history occurs in the future and that historians must make clear the path to the future based on the developments of the past.

How do you understand the purpose of teaching history. Do we use history to explain the present or the future?
