To rectify past blunders is impossible, but we might profit by the experience of them.

You learn from a conglomeration of the incredible past - whatever experience gotten in any way whatsoever.

The uncertainty and importance of the present reduce the past and future to comparative insignificance, and clear the mind of minor worries. And when all is over, memories remain which few men do not hold precious.

To bring together the records of the past and to house them in buildings where they will be preserved for the use of men and women in the future, a Nation must believe in three things. It must believe in the past. It must believe in the future. It must, above all, believe in the capacity of its own people so to learn from the past that they can gain in judgment in creating their own future.

If we open a quarrel between past and present we shall find that we have lost the future.

A nation that forgets its past has no future.
