" More than once, I've seen you talk yourself into the wrong decision by thinking too much. But if you could manage to climb out of that labyrinth of a brain long enough to discover what you want... not what you decide you should want, but what your instinct tells you... you might find what your soul is calling for."
"I don't have a soul. There's no such thing."
Looking exasperated and amused, Winterborne asked, "Then what keeps your brain working and your heart beating?"
"Electrical impulses. An Italian scientist by the name of Galvani proved it a hundred years ago, with a frog."
Firmly, Winterborne said, "I can't speak for the frog, but you have a soul. And I'd say it's high time you paid attention to it. "
