本书试图用科学方法来解释意识的奥秘。在此，我并非想给出关于意识问题的直截了当的答案。我倒希望能够如此，但是目前似乎太困难了。当然，某些哲学家误认为已经解决了这一问题，但对我而言，他们的解释并不属于科学真理的范畴。这里我想做的是勾划出意识问题的本质，并提出一些如何用实验方法来研究这一问题的建议。我将要提出的是一个特定的研究策略，而不是一个充分发展的理论。我想要知道的是，当我看某个东西时，在我头脑中究竟发生了什么事情。

Nobel Prize-winning biochemist Crick (co-discoverer with James Watson of DNA's double helix structure) here takes readers to the forefront of modern brain research. Geared to serious lay readers and scientists, this speculative study argues that our minds can be explained, without recourse to religious concepts of a soul, in terms of the interactions of a vast assembly of nerve cells and associated molecules. Crick delves into the nature of consciousness by focusing on visual awareness, an active, constructive process in which the brain selectively combines discrete elements into meaningful images. Early chapters include numerous interactive illustrations to demonstrate the brain's shortcuts, tricks and habits of visual perception. In later chapters Crick discusses neural networks – electronic pathways that can remember patterns or produce spoken language – and outlines research strategies designed to pinpoint the brain's awareness neurons that enable us to see.
