"If you want to understand the human mind, you have to reject the idea that we directly perceive and remember the world as it is. Our perceptual experience isn't simply a passive impression of the input received by our senses — and our memory isn't like a photobook or a video, comprehensively recording the details of our experience."
"Take an example from visual perception. The image below seems to depict a woman behind a small girl, where the woman is much larger than the girl. But measure on the screen, and you'll discover that each figure is precisely the same height and width."
