> Crucially, Jayne's definition of "consciousness" is basically introspection. With language as a key portion. See any discussion of deaf people who aren't taught language until late in life, such a Helen Keller. The stories consistently have them emotionally overwhelmed when the first learn language. They want to know the names of everything. And also, they consistently talk about "before" and "after". Before language, they were a collection of emotions, fears, desires, etc. After language, they existed for the first time. They could name things, including themselves. This looks a lot like the transition to self aware consciousness. Which means Jayne isn't entirely wrong.
