MATTER AND MEMORY
CHAP. II

movement rather tends to drive away the image. Yet, in one way, it contributes to its approach. For, though the whole series of our past images remains present within us, still the representation which is analogous to the present perception has to be chosen from among all possible representations. Movements, accomplished or merely nascent, prepare this choice, or at the very least mark out the field in which we shall seek the image we need. By the very constitution of our nervous system, we are beings in whom present impressions find their way to appropriate movements: if it so happens that former images can just as well be prolonged in these movements, they take advantage of the opportunity to slip into the actual perception and get themselves adopted by it. They then appear, in fact, to our consciousness, though it seems as if they ought, by right, to remain concealed by the present state. So we may say that the movements which bring about mechanical recognition hinder in one way, and encourage in another, recognition by images. In principle, the present supplants the past. But, on the other hand, just because the disappearance of former images is due to their inhibition by our present attitude, those whose shape might fit into this attitude encounter less resistance than the others; and if, then, any one of them is indeed able to overcome the obstacle, it is the image most similar to the present perception that will actually do so.
