“Memory cannot be understood, either, without a mathematical approach. The fundamental given is the ratio between the amount of time in the lived life and the amount of time from that life that is stored in memory. No one has ever tried to calculate this ratio, and in fact there exists no technique for doing so; yet without much risk of error I could assume that the memory retains no more than a millionth, a hundred-millionth, in short an utterly infinitesimal bit of the lived life. That fact too is part of the essence of man. If someone could retain in his memory everything he had experienced, if he could at any time call up any fragment of his past, he would be nothing like human beings: neither his loves nor his friendships nor his angers nor his capacity to forgive or avenge would resemble ours.We will never cease our critique of those persons who distort the past, rewrite it, falsify it, who exaggerate the importance of one event and fail to mention some other; such a critique is proper (it cannot fail to be), but it doesn't count for much unless a more basic critique precedes it: a critique of human memory as such. For after all, what can memory actually do, the poor thing? It is only capable of retaining a paltry little scrap of the past, and no one knows why just this scrap and not some other one, since in each of us the choice occurs mysteriously, outside our will or our interests. We won't understand a thing about human life if we persist in avoiding the most obvious fact: that a reality no longer is what it was when it was; it cannot be reconstructed.”

Even the most voluminous archives cannot help.”

“Friendship is indispensable to man for the proper function of his memory. Remembering our past, carrying it with us always, may be the necessary requirement for maintaining, as they say, the wholeness of the self. To ensure that the self doesn't shrink, to see that it holds on to its volume, memories have to be watered like potted flowers, and the watering calls for regular contact with the witnesses of the past, that is to say, with friends. They are our mirror; our memory; we ask nothing of them but that they polish the mirror from time to time so we can look at ourselves in it.”

“Just as someone in pain is linked by his groans to the present moment (and is entirely outside past and future), so someone bursting out in such ecstatic laughter is without memory and desire, for he is emitting his shout into the world's present moment and wishes to know only that.”

“I imagine the feelings of two people meeting again after many years. In the past they spent some time together, and therefore they think they are linked by the same experience, the same recollections. The same recollections? That's where the misunderstanding starts: they don't have the same recollections; each of them retains two or three small scenes from the past, but each has his own; their recollections are not similar; they don't intersect; and even in terms of quantity they are not comparable: one person remembers the other more than he is remembered; first because memory capacity varies among individuals (an explanation that each of them would at least find acceptable), but also (and this is more painful to admit) because they don't hold the same importance for each other. When Irena saw Josef at the airport, she remembered every detail of their long-ago adventure; Josef remembered nothing. From the very first moment their encounter was based on an unjust and revolting inequality.”

“We can never know what to want, because, living only one life, we can neither compare it with our previous lives nor perfect it in our lives to come.”

“He remained annoyed with himself until he realized that not knowing what he wanted was actually quite natural. We can never know what to want, because, living only one life, we can never compare it with our previous lives nor perfect it in our lives to come.”
