One might, perhaps add, as 4: that the memory-image is most conformable to the actual one. This is not identical with the fact that we recollect at all. It is to be assumed that the forms of memory-images vary very much with different persons, because each individual verifies his images of various objects variously. I know two men equally well for an equal time, and yet have two memory-images of them. When I recall one, a life-sized, moving, and moved figure appears before me, even the very man himself; when I think of the other, I see only a small, bare silhouette, foggy and colorless, and the difference does not require that the first shall be an interesting and the second a boresome individual. This is still clearer in memory of travels. One city appears in recollection with size, color and movement, real; the other, in which I sojourned for the same length of time and only a few days later, under similar conditions of weather, etc., appears like a small, flat photograph. Inquiry reveals that this is as true of other people as of me, and that the problem of memory is much differentiated by the method of recollection. In fact, this is so little in doubt that at some periods of time there are more images of one sort than of another and what is a rule for one kind of individual is an exception for another. Now there is a series of phenomena for which we possess particular types of images which often have little to do with the things themselves. So Exner says: “We might know the physiognomy of an individual very accurately, be able to pick him out among a thousand, without being clear about the differences between him and another; indeed, we often do not know the color of his eyes and hair, yet marvel when it suddenly becomes different.” Kries[220] calls attention to another fact: “When we try to mark in memory the contour of a very well-known coin, we deceive ourselves, unbelievably--when we see the coin the size we imagine it to be, we wonder still more.”
