Commentary by John Perry

One might say, casually, he knows more about The War Hero than The War Hero himself knew about himself.

This person has two distinct kinds of self knowledge:

- Knowledge of the person one happens to be
    - This is the normal kind of self-knowledge
    - "I am a graduate student in Berkekey"
    - "I have amnesia and no memory of anything before the battle"
- Self-knowledge
    - "The War Hero was born in Cinincatti on a cold day."
    - "The War Hero was forced to wear shorts even during the winter."
        - If it's true, why is it true? Judging by the truth conditions of the sentence, it's true because a certain person born in Cininitati and was fordced to wear short pants, etc.

Most of us have both types of knowledge, but because they so easily run together we conflate the two.
