Lacking a heavily relied upon sense, the blind were unable to read by themselves. The tactile methods in existence were inefficient and not always accessible. School was hard, if they went at all, because blind students were unable to do the same work as the rest of their classmates. They couldn’t do the reading assignments unless someone read it to them. They couldn’t write their own arithmetic answers. It was hard to get a job if you couldn’t work independently. Helen Keller once said in an article about Braille, "without the word, visible or tangible, there can be no education. When one thinks of the sufferings of the sightless in all countries before they could read, one does not wonder that it was written in the Bible, 'In the beginning the Word was with God***and the Word was the light of men.'" The point she is trying to make is that education and literacy are important, and thanks to Louis Braille, a new world has been opened to so many people.
