If we contemplate forgetfulness, not memory, we shall see how completely the account of it confirms the account we have just rendered of memory. Every {332} case of forgetfulness, is a case of weakened, or extinct, association. Some years ago, I could repeat a certain discourse with accuracy and ease, from beginning to end; attempting it, the other day, I was unable to repeat more than a few sentences. The reason is obvious. The last of the words and ideas which occurred to me failed to suggest the following; that is to say, the association which formerly existed between them was dissolved. A remarkable piece of natural scenery, composed of mountains, woods, rivers, lakes, ocean, flocks, herds, cultivated fields, gay cottages, and splendid palaces, of which I had a lively recollection many years ago, presents itself to me now very much faded: in other words, a great variety of the circumstances, which make up the detail and minute features of the scene, were formerly remembered by me, but are now forgotten. And how forgotten? The manner is obvious. The greater features, which I still remember, had formerly the power of calling up the smaller along with them, and the whole scene was revived; the association gradually declining, the great objects have no longer the power to excite the idea of the small; and they are therefore gone from me for ever. There are things of which I have so entirely lost the recollection, that it never can be revived. The meaning is, that the associations which were formed between the ideas of them, and other ideas, are so completely dissolved, that none of my present ideas has the power of exciting them. It is observable, that sensations have a stronger power to excite recollections than is possessed by {333} ideas.[92] A man, after an absence of many years, revisits the scenes of his infancy: a variety of circumstances crowd into his memory, which, but for the scene before him, would never have been remembered again. These are the circumstances between which, and the perception of the pristine objects, the association is not yet dissolved. There are other circumstances, without number, which (the association being completely dissolved) not even that perception can revive, and which never can be remembered more. [Bain's footnote 92: This is for no other reason than the superior intensity or impressiveness of the actual as compared with the ideal. Although as a rule, the sensation has a greater hold of the mind, than the corresponding idea, there are exceptions. An idea may sometimes be accompanied with an intensity of mental occupation and excitement, surpassing the reality: what we have looked at with indifference when it occurred, may take on an extraordinary importance in the retrospect; in which case its power of resuscitating collateral circumstances will be far greater than the power of the original sensation.--_B._]
