Perhaps the most important work of philosophy written in the twentieth century, the Tractatus Logico-Philosophicus first appeared in 1921 and was the only philosophical work that Ludwig Wittgenstein published during his lifetime. Written in short, carefully numbered paragraphs of extreme compression and brilliance, it immediately convinced many of its readers and captivated the imagination of a generation of philosophers. Influencing the Logical positivists of the 1920s and 1930s, the book later went to grip the minds of many other philosophers, convincing many that propositions were pictures of reality. In this edition, David Pears and Brian McGuinness have completely revised their translation based upon Wittgenstein's own suggestions and comments in his correspondence with C. K. Ogden, Wittgenstein's first translator. In addition, this edition contain the introduction by Bertrand Russell which appeared in the original English.

This revised German–English edition is published on the fiftieth anniversary of Wittgenstein's death. It incorporates final revisions by G. E. M. Anscombe (1919–2001) to her original English translation.

维特根斯坦消解哲学问题的主张和方法，几乎对身边的每一个人产生着影响。这本《文化与价值》便是他独特的生活历程的写照，这位哲学家告诉我们，他从什么地方来，要到什么地方去。

《哲学语法》是维特根斯坦后期哲学的代表作，是一本公认的难以理解的著作。该书详细介绍了他的语言哲学和心理学哲学观点。他深邃而奇异的思想吸引了无数学人的目光。该书可以拓宽读者的哲学视野，而且也为我们的进一步研究提供了必要的基础。

路德维希·维特根斯坦是20世纪西方最伟大的哲学家之一。本书即是美国斯坦福大学教授W.W.巴特利倾十年心血所著的关于维特根斯坦的传记，不仅以亲历四方所搜寻的第一手资料叙述了维特根斯坦神秘莫测的成长经历及其现代、新潮的哲学观点，而且也成功地勾勒出维特根斯坦特立独行的展现了出来；其间当然也包括了为世人所瞩目的他的同性恋问题。全书虽然描述了一个非凡的人”，但却去除了维特根斯坦头上的光环，使他实实在在地活在
