But it may be asked why it is that, if we do not remember events that have occurred in past lives and people we have seen before, we do not at least now have a knowledge of the facts previously familiar to us. What the soul gains from incarnation to incarnation is not concrete facts but something higher and far more valuable. It gains the essence of facts which gives the understanding of their true relationship; and this is the thing we call good judgment or common-sense. A man does not succeed in business because he knows a lot of facts, but because he knows what to do with the facts. An encyclopedia is full of facts but it cannot run a business. Every theorist and dreamer is loaded with facts. The successful man is the one with balance and judgment. It might seem on first thought that one who has been a carpenter in a previous incarnation should have no need to learn the name and use of a saw, or one who has been a skillful penman to learn slowly to hold the pen and fashion the letters. But we must remember that the old soul is now breaking in a new physical instrument with which to express itself and that while it will be able to use all the skill it has previously evolved, its full expression must await the time when the new instrument has been brought into responsive action. The situation might be fairly illustrated by the case of a stenographer who is still using the original typewriter, in some remote corner of the earth, and who has not even seen or heard of any of the remarkable improvements made in such machines in the last thirty years. If his old machine were suddenly taken from him and a model of the present year were put in its place, it is obvious that he could at first make little use of it--not because he has no knowledge but because he must become accustomed to the new machine before he can express himself through it. It would have mechanism and appliances that he could not immediately manage. Let us imagine also that all the characters are in a foreign language which must be mastered before the machine can be used. But the difficulties are not great enough yet for a fair illustration. We must also suppose that it is a living thing, with moods and emotions, and that it must pass through stages of growth comparable to infancy and youth. Under these handicaps it would be certain that the stenographer would appear to have very little knowledge and to possess little skill. Yet as a matter of fact it is merely the conditions that temporarily prevent him from expressing his wisdom and skill.
