The Pleasures of the Past thus retained.—Of the importance of this faculty as related to other intellectual powers, I have already spoken. I refer now to its value as connected with human happiness, as the source of some of the purest pleasures of life. The present, however joyous, is fleeting and evanescent. Memory seizes the passing moment, fixes it upon the canvas, and hangs the picture on the soul's inner chambers for her to look upon when she will. Thus, in an important sense, the former years are past, but not gone. We live them over again in memory.
Instance of Niebuhr.—It is related of Carsten Niebuhr, the Oriental traveller, that "when old and blind, and so feeble that he had barely strength to be borne from his bed to his chair, the dim remembrance of his early adventures thronged before his memory with such vividness that they presented themselves as pictures upon his sightless eye-balls. As he lay upon his bed, pictures of the gorgeous Orient flashed upon his darkness as distinctly as though he had just closed his eyes to shut them out for an instant. The cloudless blue of the eastern heavens bending by day over the broad deserts, and studded by night with southern constellations, shone as vividly before him, after the lapse of half a century, as they did upon the first Chaldean shepherds whom they won to the worship of the host of heaven; and he discoursed with strange and thrilling eloquence upon those scenes which thus, in the hours of stillness and darkness, were reflected upon his inmost soul."
The same Thing occurs often in old Age.—Something of this kind not unfrequently occurs in advanced life. Picture to yourself an old man of many winters. The world in which his young life began has grown old with him and around him, and its brightest colors have faded from his vision. The life and stir, the whirl and tumult of the busy world, the world of to-day and yesterday, move him not. He heeds but slightly the events of the passing hour. He lives in a past world. The scenes of his childhood, the sports and companions of his youth, the hills and streams, the bright eyes and laughing faces on which his young eyes rested, in which his young heart delighted—these visit him again in his solitude, as he sits in his chair by the quiet fireside. He lives over again the past. He wanders again by the old hills, and over the old meadows. He feels again the vigor of youth. He leads again his bride to the altar. He brings home toys for his children, and enters again into their sports. And so the extremes of life meet. Age completes the circuit, and brings us back to the starting-point. We close where we began. Life is a magic ring.
The recollection of past Sorrow not always painful.—But life is not all joyous. Mingled with the brighter hues of every life are also much sadness and sorrow, and these, too, are to be remembered. It might be supposed that, while memory, by recalling the pleasing incidents of the past, might contribute much to our happiness, she would add, in perhaps an equal degree, to our sorrow, by recalling much that is painful to the thoughts. Such, however, I am convinced, is not the fact. The benevolence of the Creator has ordered it otherwise. To no one, perhaps, is memory the source of greater pleasure, strange as it may seem, than to the mourner. The very circumstances that tend to renew our grief, and keep alive our sorrow, in case of some severe calamity or bereavement, are still cherished with a melancholy satisfaction of which we would not be deprived. There is a luxury in our very grief, and in the remembrance of that for which we grieve. We would not forget what we have lost. Every recollection and association connected with it are sacred. Time assuages our grief, but impairs not the strength and sacredness of those associations, nor diminishes the pleasure with which we recall the forms we shall see no more, and the scenes that are gone forever. Every memento of the departed one is sacred; the books, the flowers, the favorite walks, the tree in whose shadow he was wont to recline, all have a significance and a value which the stricken heart only can interpret, and which memory only can afford.
We recollect the Past as it was.—It is to be noticed, also, that, in such cases, the picture which memory furnishes is a transcript of the past as it was; the image is stereotyped and unchangeable. Other things change, we change; that changes not. It has a fixed value. A mother, for instance, loses a child of three years. It ever remains to her a child of three years. She remembers it as it was. She grows old; twenty summers and winters pass; yet as often as she visits the little mound, now scarce to be distinguished from the level surface, there comes to her recollection that little child as he was, when she hung, for the last time, over that pale, sweet face that she should see no more. She still thinks of him, dreams of him, as a child, for it is as such only that she remembers him.
Blessed boon, that gives us just the past; when all things change, fortunes vary, friends depart, the world grows unkind, and we grow old, the former things remain treasured in our memory, and we can stand as mourners at the grave of what we once were.
VIII. Historical Sketch.—Different Theories Of Memory.
Ancient Theory.—The idea formerly, and almost universally entertained respecting the modus operandi of the faculty we call memory, was, that in perception and the various operations of the senses, certain impressions are made on the sensorium—certain forms and types of things without, certain images of them—which remain when the external object is no longer present, and become imprinted thus on the mind. Such, certainly, was the doctrine of the earliest Greek commentators on Aristotle. Such, I must think, is substantially the doctrine of Aristotle himself.
Theory of Aristotle.—His idea is, that memory, as well as imagination, primarily and directly, relates only to sensible objects, and gives us only images of these objects, and even when it gives us strictly intellectual objects, gives us these only by images. One cannot think, he says, without images. Its source and origin, then, he concludes, is the sensibility, and so it pertains to animals, as well as men; only to those, however, which have the perception of time, since memory is a modification of sensation or intellectual conception, under the condition of time past. Such being, in his view, the nature and source of memory, he goes on to ask how it is that only a modification (or state) of the mind being present, and the object itself absent, one recalls that absent object?
