This is not specific to autism (it's more general with regards to developmental disability) but certainly pertains to many autistic people, and in a way people in general. This book is about communication with people who are said to have no communication (a concept he firmly rejects), who he refers to as a "linguistic minority of one". He encourages people to get beyond reflections of themselves and into truly making contact with another person.
The topic may sound like dry reading, but Hingsburger is never dry reading. He draws (as always) on his own experiences in the human services field and the way in which he's matured in relation to those experiences. And he (as always) doesn't shy away from topics most people in his field ignore.
It's from this book, also, that I got the quote from Dick Sobsey I used in another post. The full paragraph, in response to a question about how Sobsey protected his son:
"I take my son out into the community, I want my neighbours to know him. I want his teachers and the people who care for him to know him. Know him as a person. I feel that once they meet him. Really meet him, he is safer. People don't hurt people. People hurt things."
It's a small book, 40 pages, and I think it sells for about $5 in American dollars, but it could sell for more than that and be worth it.
