What is the speech in Wizard of

The most famous speech in The Wizard of Oz is the "Tin Man" speech, in which the Tin Man expresses his desire for a heart. He says, "I don't know who I am, or what I want, or even what I feel. All I know is that I'm incomplete. I'm missing something essential. And I think it's a heart." This speech encapsulates the Tin Man's journey of self-discovery and his ultimate realization that he already had a heart all along.
