2. Which of the following become true the moment somebody honestly utters them

A. I am speaking B. I am writing    

C. I am a human being

D. I am not sure  
Ask a friend
       

(A) looks as though it might be 'self-validating' in this sense.

What about (C)? If we are talking about 'someone' saying 'I am a human being' would that not be self-validating? But it doesn't become true on being uttered ...

(D) might be false

(B) probably is.
