盲人能看见吗？这个想法似乎自相矛盾。然而，如果我们把“看”看作是产生可能包含视觉细节的内部心理表征的能力，盲视的想法就成了一个有待研究的概念。在这本书中，Zaira Cattaneo和Tomaso Vecchi研究了失明和其他类型的视觉缺陷对人类认知系统的发展和功能的影响。利用行为和神经生理学数据，Cattaneo和Vecchi分析了完全或严重视觉障碍个体在感觉，认知和皮层水平上的心理意象，空间认知和补偿机制的研究。他们发现我们的大脑不需要我们的眼睛来“看”。Cattaneo和Vecchi解决了具有广泛重要性的关键问题：视觉感知与图像和工作记忆的关系以及心理图像依赖于正常视觉的程度;视觉和其他感官之间的功能和神经关系;视觉体验的特定方面对认知发展或特定的认知机制至关重要;以及大脑非凡的可塑性--正如盲人的视觉皮层可能被重组以支持其他感知或认知功能所说明的那样。在没有视觉的情况下，其他感官作为功能性替代品发挥作用，并且通常得到改善。在《盲视》一书中，卡塔内奥和韦基提出了“视觉的暴政”，指出了其他感官在认知中的重要性。
Can a blind person see? The very idea seems paradoxical. And yet, if we conceive of "seeing" as the ability to generate internal mental representations that may contain visual details, the idea of blind vision becomes a concept subject to investigation. In this book, Zaira Cattaneo and Tomaso Vecchi examine the effects of blindness and other types of visual deficit on the development and functioning of the human cognitive system. Drawing on behavioral and neurophysiological data, Cattaneo and Vecchi analyze research on mental imagery, spatial cognition, and compensatory mechanisms at the sensorial, cognitive, and cortical levels in individuals with complete or profound visual impairment. They find that our brain does not need our eyes to "see." Cattaneo and Vecchi address critical questions of broad importance: the relationship of visual perception to imagery and working memory and the extent to which mental imagery depends on normal vision; the functional and neural relationships between vision and the other senses; the specific aspects of the visual experience that are crucial to cognitive development or specific cognitive mechanisms; and the extraordinary plasticity of the brain -- as illustrated by the way that, in the blind, the visual cortex may be reorganized to support other perceptual or cognitive funtions. In the absence of vision, the other senses work as functional substitutes and are often improved. With Blind Vision, Cattaneo and Vecchi take on the "tyranny of the visual," pointing to the importance of the other senses in cognition.
