“I have often observed, that on mimicking the looks and gestures of angry, or placid, or frighted, or daring men, I have involuntarily found my mind turned to that passion, whose appearance I endeavored to imitate; nay, I am convinced it is hard to avoid it, though one strove to separate the passion from its correspondent gestures. Our minds and bodies are so closely and intimately connected, that one is incapable of pain or pleasure without the other.”
