45. Measure! nay, you cannot measure. Who shall measure the difference between the power of those who "do and teach," and who are greatest in the kingdoms of earth, as of heaven--and the power of those who undo, and consume--whose power, at the fullest, is only the power of the moth and the rust? Strange! to think how the Moth-kings lay up treasures for the moth; and the Rust-kings, who are to their peoples' strength as rust to armor, lay up treasures for the rust; and the Robber-kings, treasures for the robber; but how few kings have ever laid up treasures that needed no guarding--treasures of which, the more thieves there were, the better! Broidered robe, only to be rent; helm and sword, only to be dimmed; jewel and gold, only to be scattered;--there have been three kinds of kings who have gathered these. Suppose there ever should arise a Fourth order of kings, who had read, in some obscure writing of long ago, that there was a Fourth kind of treasure, which the jewel and gold could not equal, neither should it be valued with pure gold. A web made fair in the weaving, by Athena's shuttle; an armor, forged in divine fire by Vulcanian force--a gold to be mined in the sun's red heart, where he sets over the Delphian cliffs;--deep-pictured tissue, impenetrable armor, potable gold!--the three great Angels of Conduct, Toil, and Thought, still calling to us, and waiting at the posts of our doors, to lead us, with their winged power, and guide us, with their unerring eyes, by the path which no fowl knoweth, and which the vulture's eye has not seen! Suppose kings should ever arise, who heard and believed this word, and at last gathered and brought forth treasures of--Wisdom--for their people? 46. Think what an amazing business _that_ would be! How inconceivable, in the state of our present national wisdom! That we should bring up our peasants to a book exercise instead of a bayonet exercise!--organize, drill, maintain with pay, and good generalship, armies of thinkers, instead of armies of stabbers!--find national amusement in reading-rooms as well as rifle-grounds; give prizes for a fair shot at a fact, as well as for a leaden splash on a target. What an absurd idea it seems, put fairly in words, that the wealth of the capitalists of civilized nations should ever come to support literature instead of war! 47. Have yet patience with me, while I read you a single sentence out of the only book, properly to be called a book, that I have yet written myself, the one that will stand (if anything stand) surest and longest of all work of mine.
