Seeing that Harry seemed somewhat puzzled, Grindelwald chuckled. "Don't understand?"
"I don't." Harry nodded.
Grindelwald explained, "Never mind those stupid animals with no self-awareness. Any creature capable of recognizing itself has a soul. So, do you understand? Not all living creatures have souls."
