For the ideas and generalizations thus mainly formed from the images and impressions received in childhood become, in later years, the elements of the machinery, so to speak, by which all his mental operations are performed. Thus they seem to constitute more than the mere furniture of the mind; they form, as it were, almost a part of the structure itself. So true, indeed, is this, and so engrossing a part does what remains in the mind of former impressions play in its subsequent action, that some philosophers have maintained that the whole of the actual consciousness of man consists only in the resultant of all these impressions preserved more or less imperfectly by the memory, and made to mingle together in one infinitely complicated but harmonious whole. Without going to any such extreme as this, we can easily see, on reflection, how vast an influence on the ideas and conceptions, as well as on the principles of action in mature years, must be exerted by the nature and character of the images which the period of infancy and childhood impresses upon the mind. All parents should, therefore, feel that it is not merely the present welfare and happiness of their child that is concerned in their securing to him a tranquil and happy childhood, but that his capacity for enjoyment through life is greatly dependent upon it. They are, in a very important sense, intrusted with the work of building up the structure of his soul for all time, and it is incumbent upon them, with reference to the future as well as to the present, to be very careful what materials they allow to go into the work, as well as in what manner they lay them.

Among the other bearings of this thought, it gives great weight to the importance of employing gentle measures in the management and training of the young, provided that such measures can be made effectual in the accomplishment of the end. The pain produced by an act of hasty and angry violence to which a father subjects his son may soon pass away, but the memory of it does not pass away with the pain. Even the remembrance of it may at length fade from the mind, but there is still an effect which does not pass away with the remembrance. Every strong impression which you make upon his perceptive powers must have a very lasting influence, and even the impression itself may, in some cases, be forever indelible.

Let us, then, take care that these impressions shall be, as far as possible, such as shall be sources of enjoyment for them in future years. It is true that we must govern them. They are committed to our charge during the long time which is required for the gradual unfolding of their embryo powers for the express purpose that during that interval they may be guided by our reason, and not by their own. We can not surrender this trust. But there is a way of faithfully fulfilling the duties of it—if we have discernment to see it, and skill to follow it—which will make the years of their childhood years of tranquillity and happiness, both to ourselves and to them.
