One of the brothers, for instance, was very fond of astronomy. He had his observatory on a lofty tower, which stood pretty clear of the others, towards the north and east. But hitherto, his astronomy, as he had called it, had been more of the character of astrology. Often, too, he might have been seen directing a heaven-searching telescope to catch the rapid transit of a fiery shooting-star, belonging altogether to the earthly atmosphere, and not to the serene heavens. He had to learn that the signs of the air are not the signs of the skies. Nay, once, his brother surprised him in the act of examining through his longest tube a patch of burning heath upon a distant hill. But now he was diligent from morning till night in the study of the laws of the truth that has to do with stars; and when the curtain of the sunlight was about to rise from before the heavenly worlds which it had hidden all day long, he might be seen preparing his instruments with that solemn countenance with which it becometh one to look into the mysterious harmonies of Nature. Now he learned what law and order and truth are, what consent and harmony mean; how the individual may find his own end in a higher end, where law and freedom mean the same thing, and the purest certainty exists without the slightest constraint. Thus he stood on the earth, and looked to the heavens.
Another, who had been much given to searching out the hollow places and recesses in the foundations of the castle, and who was often to be found with compass and ruler working away at a chart of the same which he had been in process of constructing, now came to the conclusion, that only by ascending the upper regions of his abode could he become capable of understanding what lay beneath; and that, in all probability, one clear prospect, from the top of the highest attainable turret, over the castle as it lay below, would reveal more of the idea of its internal construction, than a year spent in wandering through its subterranean vaults. But the fact was, that the desire to ascend wakening within him had made him forget what was beneath; and having laid aside his chart for a time at least, he was now to be met in every quarter of the upper parts, searching and striving upward, now in one direction, now in another; and seeking, as he went, the best outlooks into the clear air of outer realities.
