To repeat what others have thought is not at all evidence that he who remembers is thinking. Great thoughts are often repeated thoughtlessly. A man's Occupation betrays him or establishes his claim to Knowledge. That which a man does proclaims that which he thinks or in his thoughtlessness finds him out. Of course, when the man had learned this, he said at first, quite wrongly, that his school days were wasted. He said that what he had called his education was all a mistake--that it was vanity only and wholly worthless. But, as he went on gaining ever more and more Knowledge from the thing that he was doing, and, through that thing, of many other things, he came to understand that his school days were not wasted but very well spent indeed. He came to see that what he had called education was not a mistake. He came to understand that what was wrong was this: he had considered his education complete, finished, when he had only been prepared to begin. He had considered his schooling as an end to be gained when it was only a means to the end. He had considered his learning as wealth to hold when it was capital to invest. He had mistaken the thoughts that he received from others for Knowledge when they were given him only to inspire and to help him in acquiring Knowledge. And then, of this knowledge of Knowledge gained by the man from his Occupation, there was born in him a mighty passion, a burning desire. It was the passion for Knowledge. It was the desire to know. To know the thing that he had found to do was not enough. He determined to use that knowledge to gain Knowledge of many other things. He felt within himself a new strength stirring--the strength of thought. He saw that knowledge of things led ever to more knowledge, even as link to link in a golden chain. One end of the chain he held in his Occupation; the other was somewhere, far beyond his sight, hidden in the mists that shroud the Infinite Fact, fast to the mighty secret of Life itself. Link by link, he determined to follow the chain. From knowing things to knowledge of other things he would go even until he held in his grip the last link--until he held the key to the riddle--until he knew the answer to the sum of Life.
