Suppose you've been surreptitiously doing me good deeds for months. If I "thank my lucky stars" when it is really you I should be thanking, it would misrepresent the situation to say that I believe in you and am grateful to you. Maybe I am a fool to say in my heart that it is only my lucky stars that I should thank—saying, in other words, that there is nobody to thank—but that is what I believe; there is no intentional object in this case to be identified as you.

Suppose instead that I was convinced that I did have a secret helper but that it wasn't you—it was Cameron Diaz. As I penned my thank-you notes to her, and thought lovingly about her, and marveled at her generosity to me, it would surely be misleading to say that you were the object of my gratitude, even though you were in fact the one who did the deeds that I am so grateful for. And then suppose I gradually began to suspect that I had been ignorant and mistaken, and eventually came to the correct realization that you were indeed the proper recipient of my gratitude. Wouldn't it be strange for me to put it this way: "Now I understand: you are Cameron Diaz!"
