Dyslexia, with its seemingly untidy mix of genetic talents and cultural weaknesses, exemplifies human diversity—with all the important gifts this diversity bestows on human culture. Picasso’s Guernica, Rodin’s Thinker, Gaudi’s La Pedrera, and Leonardo’s Last Supper are icons as real and as expressive of our intellectual evolution as any written text. That all these were created by individuals who more than likely were dyslexic is not coincidental.
