In this paper the author attempts to relate, on the basis of his experience, a condition - dyslexia - to the fact that some of the world's languages are written in different directions from others. He believes that human beings are "pre-programmed" (visually and mentally), some to be able to learn one language more easily, some another. The dyslexic seems to be sufferering from a mixture of this built-in information, and thus to have trouble, particularly in reading.
