眼睛是灵魂的窗户……到目前现在也证实了这种见解。与自我意识最紧密相关的大脑部分，腹侧前额叶皮层直接位于眼睛后面。因此，这就是我们所在的地方 - 如果可以在任何地方找到灵魂的地方。
(The eyes are the window of the soul…it was such a well-worn adage, a cliché by now, but Isabel had read that neuroscience, which was validating so many intuitive, ancient beliefs about who we were and how we lived our lives, now confirmed this insight too. The part of the brain that was most closely associated with self-awareness, the ventromedial prefrontal cortex, lay directly behind the eyes. So that was where we were located-that was where the soul was to be found, if it were to be found anywhere.)
