“There is, however, no advantage in reflections on the past further than may be of service to the present. For the future we must provide by maintaining what the present gives us and redoubling our efforts; it is hereditary to us to win virtue as the fruit of labour, and you must not change the habit, even though you should have a slight advantage in wealth and resources; for it is not right that what was won in want should be lost in plenty.”

Thought at Sunrise (2007)
Context: We should not be obsessed with the present alone, we must heed the past too. Is it fair, for instance, to see only the 25 ft. tall tree and forget the seed that brought it forth? Will the tree accept it if we forget the seed of it all? Is it possible to visualise a future without the seed? We must learn to appraise ourselves of the past if we want a meaningful present. You could call this an act of gratitude or an evaluation of reality.

Pt. III : The Positive Aspect of Ambiguity http://www.marxists.org/reference/subject/ethics/de-beauvoir/ambiguity/ch03.htm#s2, Ch. 1 : The Aesthetic Attitude
The Ethics of Ambiguity (1947)
Context: We must not confuse the present with the past. With regard to the past, no further action is possible. There have been war, plague, scandal, and treason, and there is no way of our preventing their having taken place; the executioner became an executioner and the victim underwent his fate as a victim without us; all that we can do is to reveal it, to integrate it into the human heritage, to raise it to the dignity of the aesthetic existence which bears within itself its finality; but first this history had to occur: it occurred as scandal, revolt, crime, or sacrifice, and we were able to try to save it only because it first offered us a form. Today must also exist before being confirmed in its existence: its destination in such a way that everything about it already seemed justified and that there was no more of it to reject, then there would also be nothing to say about it, for no form would take shape in it; it is revealed only through rejection, desire, hate and love. In order for the artist to have a world to express he must first be situated in this world, oppressed or oppressing, resigned or rebellious, a man among men. But at the heart of his existence he finds the exigency which is common to all men; he must first will freedom within himself and universally; he must try to conquer it: in the light of this project situations are graded and reasons for acting are made manifest.
