Transactional Analysis: I'm OK You're OK

(a book by Thomas A. Harris)
"I am a person. You are a person. Without you I am not a person, for only through you is language made possible and only through language is thought made possible, and only through thought is humanness made possible. You have made me important, Therefore, I am important and you are important. If I devalue you, I devalue myself." (Harris, 1969: page 223)
