《猜想与反驳》围绕着知识通过猜想与反驳、不断清除错误而增长这一主题展开论述，广泛涉猎知识论、科学论、真理论以及自然科学史和社会科学史等领域。

《科学发现的逻辑》主要讨论知识理论的两个基本问题：划界和归纳问题。作者论证科学与非科学的划界标准不是可证实性而是可证伪性，科学的方法不是归纳法而是演绎检验法。书中提出的有关科学的性质和方法以及科学知识增长的独创性论点，对科学哲学、认识论、逻辑学、方法论以及科学史、自然科学、医学、设计理论、社会科学均有影响。一些著名科学家都认为他的方法符合科学研究的实际。

卡尔・波普尔是20世纪最重要的思想家、哲学家。他的思想和作品从1970年代末开始被介绍到我国，到现在，他的一些主要著作都已经有了中译本，有些甚至有几个中译本。这本《二十世纪的教训》是卡尔・波普尔在生命中最后几年发表的两个演讲和接受意大利记者贾恩卡洛・博塞蒂（Giancarlo Bosetti）访谈的记录。和他的其他作品不同，这本书更多地表达了卡尔・波普尔对过去的这个世纪的看法，对这个世界的苦难和希望的关怀。他谈了冷战结束后的世界，谈了波斯尼亚战争，谈了媒体的危险，谈了知识分子的责任……由于是访谈和演讲，加上波普尔一贯的清晰风格，这本书在阅读上也非常容易。

On its publication in 1957, The Poverty of Historicism was hailed by Arthur Koestler as 'probably the only book published this year which will outlive the century.'
A devastating criticism of fixed and predictable laws in history, Popper dedicated the book to all those 'who fell victim to the fascist and communist belief in Inexorable Laws of Historical Destiny.' Short and beautifully written, it has inspired generations of readers, intellectuals and policy makers. One of the most important books on the social sciences since the Second World War, it is a searing insight into the ideas of this great thinker.

'If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, to belittle them. It springs rather from my conviction that, if our civilization is to survive, we must break with the habit of deference to great men.' - Karl Popper, from the Preface Written in political exile during the Second World War and first published in two volumes in 1945, Karl Popper's The Open Society and Its Enemies is one of the most influential books of all time. Hailed by Bertrand Russell as a 'vigorous and profound defence of democracy', its now legendary attack on the philosophies of Plato, Hegel and Marx exposed the dangers inherent in centrally planned political systems and through underground editions become an inspiration to lovers of freedom living under communism in Eastern Europe. Popper's highly accessible style, his erudite and lucid explanations of the thoughts of great philosophers and the recent resurgence of totalitarian regimes around the world are just three of the reasons for the enduring popularity of The Open Society and Its Enemies and why it demands to be read today and in years to come.

This new book, under the impressive editorship of Thomas Boylan and Paschal O'Gorman, explores a number of major themes central to the work of Karl Popper. The tensions that have resulted from Popperian thought are well documented. How can mainstream orthodox economics be falsifiable while privileging its core of rationality as unquestionable? This book includes expert contributions from thinkers such as Tony Lawson, K. Vela Velupillai and John McCall, who discuss this issue with renewed academic rigour.

Realism and the Aim of Science is one of the three volumes of Karl Popper's Postscript to the Logic of scientific Discovery. The Postscript is the culmination of Popper's work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science. Realism and the Aim of Science is the first volume of the Postcript. Popper here formulates and explains his non-justificationist theory of knowledge: science aims at true explanatory theories, yet it can never prove, or justify, any theory to be true, not even if is a true theory. Science must continue to question and criticise all its theories, even those that happen to be true. Realism and the Aim of Science presents Popper's mature statement on scientific knowledge and offers important insights into his thinking on problems of method within science.
