shall have less difficulty in representing to ourselves a psychical state which is unconscious, that is to say, ineffective. Whatever idea we may frame of consciousness in itself, such as it would be if it could work untrammelled, we cannot deny that, in a being which has bodily functions, the chief office of consciousness is to preside over action and to enlighten choice. Therefore it throws light on the immediate antecedents of the decision, and on those past recollections which can usefully combine with it; all else remains in shadow. But we find here once more, in a new form, the ever-recurrent illusion which, throughout this work, we have endeavoured to dispel. It is supposed that consciousness, even when linked with bodily functions, is a faculty that is only accidentally practical, and is directed essentially towards speculation. Then, since we cannot see what interest, devoted as it is supposed to be to pure knowledge, it would have in allowing any information that it possesses to escape, we fail to understand why it refuses to throw light on something that was not entirely lost to it. Whence we conclude that it can possess nothing more de jure than what it holds de facto, and that, in the domain of consciousness, all that is real is actual. But restore to consciousness its true rôle: there will no longer be any more reason to say that the past effaces itself as soon as perceived, than there is to suppose that material objects cease to exist when we cease to perceive them.
