 Even if you know many facts about Napoleon, it doesn’t follow that you know Napoleon. You couldn’t ever have known Napoleon, since he died long before you were born. But, despite not having ever known Napoleon, you could still know a great many facts about Napoleon—perhaps you know even more facts about Napoleon than did those who knew him most intimately. This shows that knowing a person is not the same as knowing a great many facts about the person: the latter is not sufficient for the former. And perhaps the former is not even sufficient for the latter, since I might know my next door neighbor, and yet not realize that he is an undercover agent, and that almost everything he tells me about himself is false.
