本书研究的是维特根斯坦生活和思想中最富于魅力的一个侧面，即维特根斯坦本人最为专注，而长期以来为学界所忽视的伦理和宗教问题。通过集中研究维氏思想的这一方面，作者分析指出了其关于逻辑与宗教关系的观点：对于维特根斯坦，道德上和智力上的双重义务紧密联系在一起，像其他行为与态度一样，语言的使用和逻辑推理所强加的责任既带来了回报，又带来了风险，罪由此产生。正如维特根斯坦回答罗素时所说，逻辑与罪，两者都是。本书是西方英语学界第一个正面处理维特根斯坦宗教意识的著作，分析细致，材料翔实，具有相当的原创性。

《关于数学基础的评论》的选文绝大部分是王宇光翻译的，《哲学语法》的选文绝大部分是刘畅翻译的。译文品质都很好，但我还是仔细做了修正。本选集中其他译文都是我自己的，除了极少数例外，例如选自马尔康姆《回忆维特根斯坦》的几段，是我直接从中译本抄下的。如前提示，这个选本中的有些段落由于脱离上下文较为费解，在翻译时做了少许通俗化的处理。有时我的译文主要根据卑尔根维特根斯坦文库的德文电子版全集The Bergen Electronic Edition ，参照以英文的电子版全集，Blackwell Publishers 出版的The Collected Works of Ludwig Wittgenstein 。我在翻译时经常参考已有的中文译文，在此对维特根斯坦的其他中译者表示感谢。　　我希望今后还有机会改善这个选本。为此，我希望同好从各个方面给予批评。（陈嘉映《维特根斯坦读本》选编说明）

本书是迄今为止最具权威性的维特根斯坦传记，自出版以来广受赞誉。

《哲学研究》讲述了：在西方哲学史上，维特根斯坦是唯一创造了两种不同哲学而又各自产生重大影响的哲学家。前期以《逻辑哲学论》为代表，后者则以《哲学研究》为象征。《哲学研究》告别了传统西方哲学以理想语言为基础、试图探索语言本质的静态逻辑构造论，重新将语言哲学捡回到日常语言中，将语言的实际运用、语言的功能作用作为出发点。他所提出的“语言游戏”和“家族类似”对语言哲学的发展贡献基本。《哲学研究》译者陈嘉映为海德格尔《存在与时间》的译者。《哲学研究》直接译自维氏的德文原本，因而是迄今中国最贴切、最准确的这一哲学名著的译本。

《汉译经典(02):文化和价值》是作者的札记性著作，收录了作者1914年到1951年关于哲学、历史、宗教、科学、教育、心理学、逻辑学、语义学、语言学、伦理学、美学、艺术等问题的评论，简练如洗，议论精深。这些评论既是维特根斯坦主要著作和重要观点的萌芽或酝酿，又是这位哲学大师理论发展的重要佐证，更是维特根斯坦所代表的流派及其学说的“万花筒”。

《维特根斯坦笔记》又名《杂论集》、《文化与价值》，是著名哲学家路德维希·维特根斯坦从25岁直到他去世为止所作的格言式笔记精选集，由维特根斯坦的密友、弟子和遗嘱执行人冯·赖特教授选编而成，内容涉及音乐、建筑、哲学、文学、宗教等不同范畴。

《战时笔记》(1914-1917年)是奥地利哲学家维特根斯坦写于1914-1917年的战时笔记。记录了作者当时的生活和心理状态，同时也记录了作者对哲学问题所作的思考。《战时笔记》(1914-1917年)是了解维特根斯坦前期思想的重点文献。

Mathieu Marion offers a careful, historically informed study of Wittgenstein's philosophy of mathematics. This area of his work has frequently been undervalued by Wittgenstein specialists and by philosophers of mathematics alike; but the surprising fact that he wrote more on this subject than on any other indicates its centrality in his thought. Marion traces the development of Wittgenstein's thinking in the context of the mathematical and philosophical work of the times, to make coherent sense of ideas that have too often been misunderstood because they have been presented in a disjointed and incomplete way. In particular, he illuminates the work of the neglected 'transitional period' between the Tractatus and the Investigations. Marion shows that study of Wittgenstein's writings on mathematics is essential to a proper understanding of his philosophy; and he also demonstrates that it has much to contribute to current debates about the foundations of mathematics.
