In considering the question of character, with its various irregularities and idiosyncracies, we shall have to accustom ourselves to dealing with factors which do not exist in consciousness at all. Strange as it may seem to the uninitiated, many of our thoughts, ideas, and motives are quite outside our normal consciousness, and of them only the resulting emotions and actions appear on the surface. This may be taken as an absolute and indisputable fact, and one which the reader should try to appreciate at the outset, although it is somewhat difficult to realise, for we always find it hard to apprehend and understand something which we can neither see nor touch. If one were to tell the ordinary labourer that water is composed of two gases which when combined form a liquid, he would probably be quite incredulous, and possibly in his ignorance might even deny emphatically any such possibility, on the grounds that it was against all common-sense and experience; he failing to realise, of course, how very limited were both his sense and his experience. In spite of his feelings of absolute certainty, and in spite of complete faith in the unshakable logic behind his belief, he would be wrong. While it is not to be expected that many readers of this book will deny the existence of the unconscious part of the mind, it may well be that many will fail to realise that it is of more than theoretical value. It therefore becomes necessary for us to examine the matter somewhat carefully, and to familiarise ourselves with the ideas of the working of this unconscious mind. Without going into the further sub-divisions recognised in psychology, we will confine ourselves to dividing the mind into two parts--the conscious and the unconscious. _And of these, at any given moment, the conscious is by far the smaller part._ We are actually conscious at any moment of but very few things, such as the book we are reading, the chair we are sitting on, and dimly of our immediate surroundings. A thousand memories which we might conjure up of our childhood and our past are, for the time being, far from consciousness. Yet these matters exist somewhere in the mind, for we are able, if we choose, to search about in it, and bring them into consciousness, even though we may not have thought of them for many years. This leads us at once to a striking fact, namely, that while many things can be remembered at will, others which we feel we ought to remember, cannot be brought to mind at all. It is an extremely common experience to find that one has forgotten a name completely, and that no effort will bring it into consciousness, yet later on, apparently without effort, the name will “come back to us,” as we say. In fact, the very phrase we use--“come back to us”--implies that it has been somewhere away from us, that it has been lodged in some place that is foreign and unknown to us, yet which we are aware is somewhere within us.
