Book excerpt: The idea that some people think differently, though no less humanly, is explored in this inspiring book. Temple Grandin is a gifted and successful animal scientist, and she is autistic. Here she tells us what it was like to grow up perceiving the world in an entirely concrete and visual way - somewhat akin to how animals think, she believes - and how it feels now. Through her finely observed understanding of the workings of her mind she gives us an invaluable insight into autism and its challenges.
