The authentic history of Kaspar Hauser is a useful hint 194:18 as to the frailty and inadequacy of mortal mind. It proves beyond a doubt that education consti- tutes this so-called mind, and that, in turn, 194:21 mortal mind manifests itself in the body by the false sense it imparts. Incarcerated in a dungeon, where neither sight nor sound could reach him, at the age of 194:24 seventeen Kaspar was still a mental infant, crying and chattering with no more intelligence than a babe, and realizing Tennyson's description: 194:27 An infant crying in the night, An infant crying for the light, And with no language but a cry. 194:30 His case proves material sense to be but a belief formed by education alone. The light which affords us joy gave 195:1 him a belief of intense pain. His eyes were inflamed by the light. After the babbling boy had been taught to 195:3 speak a few words, he asked to be taken back to his dun- geon, and said that he should never be happy elsewhere. Outside of dismal darkness and cold silence he found no 195:6 peace. Every sound convulsed him with anguish. All that he ate, except his black crust, produced violent retchings. All that gives pleasure to our educated senses 195:9 gave him pain through those very senses, trained in an opposite direction. Useful knowledge The point for each one to decide is, whether it is mortal 195:12 mind or immortal Mind that is causative. We should forsake the basis of matter for meta- physical Science and its divine Principle. 195:15 Whatever furnishes the semblance of an idea governed by its Principle, furnishes food for thought. Through as- tronomy, natural history, chemistry, music, mathematics, 195:18 thought passes naturally from effect back to cause. Academics of the right sort are requisite. Observa- tion, invention, study, and original thought are expansive 195:21 and should promote the growth of mortal mind out of it- self, out of all that is mortal. It is the tangled barbarisms of learning which we 195:24 deplore, - the mere dogma, the speculative theory, the nauseous fiction. Novels, remarkable only for their exaggerated pictures, impossible ideals, and specimens 195:27 of depravity, fill our young readers with wrong tastes and sentiments. Literary commercialism is lowering the intellectual standard to accommodate the purse and to 195:30 meet a frivolous demand for amusement instead of for improvement. Incorrect views lower the standard of truth.
