"The physiological study of mental conditions is thus the most powerful ally of hortatory ethics. The hell to be endured hereafter, of which theology tells, is no worse than the hell we make for ourselves in this world by habitually fashioning our characters in the wrong way. Could the young but realize how soon they will become mere walking bundles of habits, they would give more heed to their conduct while in the plastic state. We are spinning our own fates, good or evil, and never to be undone. Every smallest stroke of virtue or of vice leaves its never-so-little scar. The drunken Rip Van Winkle, in Jefferson's play, excuses himself for every fresh dereliction by saying, 'I won't count this time!' Well! he may not count it and a kind heaven may not count it; but it is being counted none the less. Down among his nerve-cells and fibers the molecules are counting it, registering it, and storing it up to be used against him when the next temptation comes. Nothing we ever do is, in strict scientific literalness, wiped out. Of course this has its good side as well as its bad one. As we become permanent drunkards by so many drinks, so we become saints in the moral, and authorities and experts in the practical and scientific, spheres, by so many separate acts and hours of work. But let no youth have any anxiety about the upshot of his education, whatever the line of it may be. If he keep faithfully busy each hour of the working day, he may safely leave the final result to itself. He can with perfect certainty count on waking up some fine morning, to find himself one of the competent ones of his generation, in whatever pursuit he has singled out. Silently, between all the details of his business, the _power of judging_ in all that class of matter will have built itself up within him as a possession that will never pass away. Young people should know the truth of this in advance. The ignorance of it has probably engendered more discouragement and faintheartedness in youths embarking on arduous careers than all other causes put together." EXERCISE Exercise 1. Point out an undesirable habit that you are determined to eradicate. Describe the desirable habit which you will adopt in its place. Give the concrete steps you will take in forming the new habit. How long a time do you estimate will be required for the formation of the new habit? Mark down the date and refer back to it when you have formed the habit, to see how accurately you estimated. CHAPTER V ACTIVE IMAGINATION A very large part of the mental life of a student consists in the manipulation of images. By images we mean the revivals of things that have been impressed upon the senses. Call to mind for the moment your house-number as it appears upon the door of your home. In so doing you mentally reinstate something which has been impressed upon your senses many times; and you see it almost as clearly as if it were actually before you. The mental thing thus revived is called an image.
