“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.”

“He who travels much has this advantage over others – that the things he remembers soon become remote, so that in a short time they acquire the vague and poetical quality which is only given to other things by time. He who has not traveled at all has this disadvantage – that all his memories are of things present somewhere, since the places with which all his memories are concerned are present.”

“The faculty of memory cannot be separated from the imagination. They go hand in hand. To one degree or another, we all invent our personal pasts. And for most of us those pasts are built from emotionally colored memories.”

“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.”

“You have to begin to lose your memory, if only in bits and pieces, to realize that memory is what makes our lives. Life without memory is no life at all... Our memory is our coherence, our reason, our feeling, even our action. Without it we are nothing.”
