Imagination is a straightforward form of virtual reality. What may not be so obvious is that our ‘direct’ experience of the world through our senses is virtual reality too. For our external experience is never direct; nor do we even experience the signals in our nerves directly — we would not know what to make of the streams of electrical crackles that they carry. What we experience directly is a virtual-reality rendering, conveniently generated for us by our unconscious minds from sensory data plus complex inborn and acquired theories (i.e. programs) about how to interpret them.

So once again, any theory of the structure of the universe in all but its earliest stages must take a position on what life will or will not be doing by then. There is no getting away from it: the future history of the universe depends on the future history of knowledge. Astrologers used to believe that cosmic events influence human affairs; science believed for centuries that neither influences the other. Now we see that human affairs influence cosmic events. (查看原文)

看了时间那一章节以后我突然觉得多重宇宙就是一段 switch 代码,只要进入时间旅行虚拟现实容器很多很多次,我就可以像神一样全知。这本书翻译得非常晦涩,但是我决定近几年每年读一次,它称得上是经典作品。

虽然有些观点不是很认同,不过很多理念都让人大开眼界。

比《无穷的起源》难懂。多伊奇居然花了那么多篇幅跟唯我论、归纳主义死磕……虚拟现实、时间那几章非常值得一读。数学那一章看似激进,其实读下来感觉也还好——多伊奇没有否认数学的实在,只是将数学直观及公设也看作解释(而非绝对真理本身)。但最后对四大理论所做的大一统有些勉强。这本快读完的时候开始读莱姆的《技术大全》,二者有不少交汇的旨趣:认识论、进化论、电子脑……但莱姆远一再强调肉体机能及数亿年的进化加诸于... 比《无穷的起源》难懂。多伊奇居然花了那么多篇幅跟唯我论、归纳主义死磕……虚拟现实、时间那几章非常值得一读。数学那一章看似激进,其实读下来感觉也还好——多伊奇没有否认数学的实在,只是将数学直观及公设也看作解释(而非绝对真理本身)。但最后对四大理论所做的大一统有些勉强。这本快读完的时候开始读莱姆的《技术大全》,二者有不少交汇的旨趣:认识论、进化论、电子脑……但莱姆远一再强调肉体机能及数亿年的进化加诸于人的限制;而多伊奇——大概是有更晚近的认识范式及科技成果做底气——的乐观更甚于十七世纪的启蒙思想家。尽管多伊奇也承认,人脑更像传统计算机而非通用图灵机,但对他来说似乎不存在从理论到实践的太多限制,只要这个宇宙的物理定律允许,那便是可能的。(而这正是我无法苟同多伊奇的地方。) (展开)
