No matter how much time passes, no matter what takes place in the interim, there are some things we can never assign to oblivion, memories we can never rub away.

No matter how long we exist, we have our memories. Points in time which time itself cannot erase. Suffering may distort my backward glances, but even to suffering, some memories will yield nothing of their beauty or their splendor. Rather they remain as hard as gems.

A thing forgotten on one day will be remembered on the next. Something we have made the most strenuous efforts to recall, but all in vain, will, soon after... saunter into the mind... [T]he sphere of possible recollection may be wider than we think, and... apparent oblivion is no proof against possible recall under other conditions.

In the past, nothing is irretrievably lost, but rather, on the contrary, everything is irrevocably stored and treasured. To be sure, people tend to see only the stubble fields of transitoriness but overlook and forget the full granaries of the past into which they have brought the harvest of their lives: the deeds done, the loves loved, and last but not least, the sufferings they have gone through with courage and dignity.

There are things you forget naturally-computer passwords, your father's continuing relationship with life-and then there are things you can't forget that you wish you could.

No matter how much time has passed, these things still affect us and the world we live in. If you don't pay attention to the past, you'll never understand the future. It's all linked together.

Just as real events are forgotten, some that never were can be in our memories as if they happened.

One of the most amazing recognitions of the human mind is that time passes. Everything that we experience somehow passes into a past invisible place: when you think of yesterday and the things that were troubling you and worrying you, and the intentions that you had and the people that you met, and you know you experienced them all, but when you look for them now, they are nowhere — they have vanished… It seems to me that our times are very concerned with experience, and that nowadays to hold a belief, to have a value, must be woven through the loom of one’s own experience, and that experience is the touchstone of integrity, verification and authenticity. And yet the destiny of every experience is that it will disappear.

Some things are forever, some things are not
It's the things we remember that gave the world shock"

Time, as we experience it, is continuous; it contains no discrete “events.” The events are put there by reflection on the past. As the past becomes more remote the remembered events become fewer in num­ ber and more limited in kind. It is for psychologists to say just why we remember this and forget that, but at the end of the day, the remembered past reflects our interests. It makes us what we are now.

The bloody massacre in Bangladesh quickly covered over the memory of the Russian invasion of Czechoslovakia, the assassination of Allende drowned out the groans of Bangladesh, the war in the Sinai Desert made people forget Allende, the Cambodian massacre made people forget Sinai, and so on and so forth until ultimately everyone lets everything be forgotten. In times when history still moved slowly, events were few and far between and easily committed to memory. They formed a commonly accepted backdrop for thrilling scenes of adventure in private life. Nowadays, history moves at a brisk clip. A historical event, though soon forgotten, sparkles the morning after with the dew of novelty. No longer a backdrop, it is now the adventure itself, an adventure enacted before the backdrop of the commonly accepted banality of private life.

In the past, nothing is irretrievably lost, but rather, on the contrary, everything is irrevocably stored and treasured. To be sure, people tend to see only the stubble fields of transitoriness but overlook and forget the full granaries of the past into which they have brought the harvest of their lives: the deeds done, the loves loved, and last but not least, the sufferings they have gone through with courage and dignity.
From this one may see that there is no reason to pity the old people. Instead, young people should envy them. It is true that the old have no opportunities, no possibilities in the future. But they have more than that: Instead of possibilities in the future, they have realities in the past -the potentialities they have actualized, the meanings they have fulfilled, the values they have realized -and nothing and nobody can ever remove these assets from the past.

And every mistake. But every good thing we do as well. They are immortal, every single touch we leave behind. Even if nobody sees them or remembers them, that doesn’t matter. That trail will always be what happened, what we did, every choice. The past lives on forever. There’s no changing it.

There is no control over memory. Quite soon you find yourself being vague about an event which seemed so important at the time that you thought you'd never forget it. Or unable to recall the face of someone whom you could have sworn was there for ever. On the other hand, trivial and meaningless memories may stay with you for life. I can still shut my eyes and see Victoria grinding coffee on the pantry steps, the glass bookcase and the books in it, my father's pipe-rack, the leaves of the sandbox tree, the wallpaper of the bedroom in some shabby hotel, the hairdresser in Antibes. It's in this way that I remember buying the pink milanese silk underclothes, the assistant who sold them to me and coming into the street holding the parcel.
