5. Can you think of garrulous persons among your acquaintance the explanation of whose tiresomeness is that their association is of the complete instead of the selective type? Watch for such illustrations in conversation and in literature (e.g., Juliet's nurse).
6. Observe children in the schoolroom for good and poor training in association. Have you ever had anything that you otherwise presumably would enjoy rendered distasteful because of unpleasant associations? Pass your own methods of learning in review, and also inquire into the methods used by children in study, to determine whether they are resulting in the best possible use of association.
CHAPTER XI
MEMORY
Every hour of our lives we call upon memory to supply us with some fact or detail from out our past. Let memory wholly fail us, and we find ourselves helpless and out of joint in a world we fail to understand. A poor memory handicaps one in the pursuit of education, hampers him in business or professional success, and puts him at a disadvantage in every relation of life. On the other hand, a good memory is an asset on which the owner realizes anew each succeeding day.
1. THE NATURE OF MEMORY
Now that you come to think of it, you can recall perfectly well that Columbus discovered America in 1492; that your house is painted white; that it rained a week ago today. But where were these once-known facts, now remembered so easily, while they were out of your mind? Where did they stay while you were not thinking of them? The common answer is, "Stored away in my memory." Yet no one believes that the memory is a warehouse of facts which we pack away there when we for a time have no use for them, as we store away our old furniture.
What is Retained.—The truth is that the simple question I asked you is by no means an easy one, and I will answer it myself by asking you an easier one: As we sit with the sunlight streaming into our room, where is the darkness which filled it last night? And where will all this light be at midnight tonight? Answer these questions, and the ones I asked about your remembered facts will be answered. While it is true that, regardless of the conditions in our little room, darkness still exists wherever there is no light, and light still exists wherever there is no darkness, yet for this particular room there is no darkness when the sun shines in, and there is no light when the room is filled with darkness. So in the case of a remembered fact. Although the fact that Columbus discovered America some four hundred years ago, that your house is of a white color, that it rained a week ago today, exists as a fact regardless of whether your minds think of these things at all, yet the truth remains as before: for the particular mind which remembers these things, the facts did not exist while they were out of the mind.
It is not the remembered fact which is retained, but the power to reproduce the fact when we require it.
