§ 16.
Experience of the latter kind must be experience of matters of fact recognised as such. It is possible, no doubt, to imagine a psychological history of this experience, and to trace it back to a stage in whichthe distinction between fact and fancy is not yet formally recognised. But there is a limit to this process. An experience which distinguishes fact from fancy cannot be developed out of one which is not, in some form or other, a consciousness of events as related or as a series of changes. It has commonly, and with much probability, been held that the occurrence of the unexpected, by exciting distrust in previously established associations of ideas, has at any rate a large share in generating the distinction of what seems from what is. But the shock of surprise is one thing, the correction of a belief quite another. Unless there were already a consciousness alike of the events, of which the ideas have become associated, as a related series, and of the newly observed event as a member of the same, the unfamiliar event might cause a disturbance of the nerves or the psychoplasm,
but there would neither be an incorrect belief as to an order of events to be corrected by it, nor any such correlation of the newly observed event with what had been observed before as could suggest a correction. But a consciousness of events as a related series—experience in the most elementary form in which it can be the beginning of knowledge—has not any element of identity with, and therefore cannot properly be said to be developed out of, a mere series of related events, of successive modifications of body or soul, such as is experience in the former of the senses spoken of. No one and no number of a series of related events can be the consciousness of the series as related. Nor can any product of the series be so either. Even if this product could be anything else than a further event, it could at any rate only be something that supervenes at a certain stage upon such of the events as have so far elapsed. But a consciousness of certain events cannot be anything that thus succeeds them. It must be equally present to all the events of which it is the consciousness. For this reason an intelligent experience, or experience as the source of knowledge, can neither be constituted by events of which it is the experience, nor be a product of them. (§ 16 ¶ 1)
