Memory is a primary and fundamental faculty, without which none other can work; the cement, the bitumen, the matrix in which the other faculties are embedded; or it is the thread on which the beads of man are strung, making the personal identity which is necessary to moral action. Without it all life and thought were an unrelated succession. As gravity holds matter from flying off into space, so memory gives stability to knowledge; it is the cohesion which keeps things from falling into a lump, or flowing in waves.
We like longevity, we like signs of riches and extent of nature in an individual. And most of all we like a great memory. The lowest life remembers. The sparrow, the ant, the worm, have the same memory as we. If you bar their path, or offer them somewhat disagreeable to their senses, they make one or two trials, and then once for all avoid it.
Every machine must be perfect of its sort. It is essential to a locomotive that it can reverse its movement, and run backward and forward with equal celerity. The builder of the mind found it not less needful that it should have retroaction, and command its past act and deed. Perception, though it were immense and could pierce through the universe, was not sufficient.
Memory performs the impossible for man by the strength of his divine arms; holds together past and present, beholding both, existing in both, abides in the flowing, and gives continuity and dignity to human life. It holds us to our family, to our friends. Hereby a home is possible; hereby only a new fact has value.
Opportunities of investment are useful only to those who have capital. Any piece of knowledge I acquire today, a fact that falls under my eyes, a book I read, a piece of news I hear, has a value at this moment exactly proportioned to my skill to deal with it. Tomorrow, when I know more, I recall that piece of knowledge and use it better.
The Past has a new value every moment to the active mind, through the incessant purification and better method of its memory. Once it joined its facts by colour and form and sensuous relations. Some fact that had a childish significance to your childhood and was a type in the nursery, when riper intelligence recalls it means more and serves you better as an illustration; and perhaps in your age has new meaning. What was an isolated, unrelated belief or conjecture, our later experience instructs us how to place in just connection with other views which confirm and expand it. The old whim or perception was an augury of a broader insight, at which we arrive later with securer conviction. This is the companion, this the tutor, the poet, the library, with which you travel. It does not lie, cannot be corrupted, reports to you not what you wish but what really befell. You say, “I can never think of some act of neglect, of selfishness, or of passion without pain.” Well, that is as it should be. That is the police of the Universe: the angels are set to punish you, so long as you are capable of such crime. But in the history of character the day comes when you are incapable of such crime. Then you suffer no more, you look on it as heaven looks on it, with wonder at the deed, and with applause at the pain it has cost you.
Memory is not a pocket, but a living instructor, with a prophetic sense of the values which he guards; a guardian angel set there within you to record your life, and by recording to animate you to uplift it. It is a scripture written day by day from the birth of the man; all its records full of meanings which open as he lives on, explaining each other, explaining the world to him and expanding their sense as he advances, until it shall become the whole law of nature and life.
As every creature is furnished with teeth to seize and eat, and with stomach to digest its food, so the memory is furnished with a perfect apparatus. There is no book like the memory, none with such a good index, and that of every kind, alphabetic, systematic, arranged by names of persons, by colours, tastes, smells, shapes, likeness, unlikeness, by all sorts of mysterious hooks and eyes to catch and hold, and contrivances for giving a hint.
The memory collects and re-collects. We figure it as if the mind were a kind of looking-glass, which being carried through the street of time receives on its clear plate every image that passes; only with this difference that our plate is iodized so that every image sinks into it, and is held there. But in addition to this property it has one more, this, namely, that of all the million images that are imprinted, the very one we want reappears in the centre of the plate in the moment when we want it.
We can tell much about it, but you must not ask us what it is. On seeing a face I am aware that I have seen it before, or that I have not seen it before. On hearing a fact told I am aware that I knew it already. You say the first words of the old song, and I finish the line and the stanza. But where I have them, or what becomes of them when I am not thinking of them for months and years, that they should lie so still, as if they did not exist, and yet so nigh that they come on the instant when they are called for, never any man was so sharp-sighted, or could turn himself inside out quick enough to find.
’Tis because of the believed incompatibility of the affirmative and advancing attitude of the mind with tenacious acts of recollection that people are often reproached with living in their memory. Late in life we live by memory, and in our solstices or periods of stagnation; as the starved camel in the desert lives on his humps. Memory was called by the schoolmen vespertina cognitio, evening knowledge, in distinction from the command of the future which we have by the knowledge of causes, and which they called matutina cognitio, or morning knowledge.

The damages of forgetting are more than compensated by the large values which new thoughts and knowledge give to what we already know. If new impressions sometimes efface old ones, yet we steadily gain insight; and because all nature has one law and meaning,—part corresponding to part,—all we have known aids us continually to the knowledge of the rest of nature. Thus, all the facts in this chest of memory are property at interest. And who shall set a boundary to this mounting value? Shall we not on higher stages of being remember and understand our early history better?
…
We learn early that there is great disparity of value between our experiences; some thoughts perish in the using. Some days are bright with thought and sentiment, and we live a year in a day. Yet these best days are not always those which memory can retain. This water once spilled cannot be gathered. There are more inventions in the thoughts of one happy day than ages could execute, and I suppose I speak the sense of most thoughtful men when I say, I would rather have a perfect recollection of all I have thought and felt in a day or a week of high activity than read all the books that have been published in a century.
The memory is one of the compensations which Nature grants to those who have used their days well; when age and calamity have bereaved them of their limbs or organs, then they retreat on mental faculty and concentrate on that. The poet, the philosopher, lamed, old, blind, sick, yet disputing the ground inch by inch against fortune, finds a strength against the wrecks and decays sometimes more invulnerable than the heyday of youth and talent.
I value the praise of Memory. And how does Memory praise? By holding fast the best. A thought takes its true rank in the memory by surviving other thoughts that were once preferred. Plato remembered Anaxagoras by one of his sayings. If we recall our own favourites we shall usually find that it is for one crowning act or thought that we hold them dear.

You may perish out of your senses, but not out of your memory or imagination.
The memory has a fine art of sifting out the pain and keeping all the joy. The spring days when the bluebird arrives have usually only few hours of fine temperature, are sour and unlovely; but when late in autumn we hear rarely a bluebird’s notes they are sweet by reminding us of the spring. Well, it is so with other tricks of memory. Of the most romantic fact the memory is more romantic; and this power of sinking the pain of any experience and of recalling the saddest with tranquillity, and even with a wise pleasure, is familiar. The memory is as the affection. Sampson Reed says, “The true way to store the memory is to develop the affections.” A souvenir is a token of love. Remember me means, Do not cease to love me. We remember those things which we love and those things which we hate. The memory of all men is robust on the subject of a debt due to them, or of an insult inflicted on them. “They can remember,” as Johnson said, “who kicked them last.”
…
Memory is a presumption of a possession of the future. Now we are halves, we see the past but not the future, but in that day will the hemisphere complete itself and foresight be as perfect as aftersight.
