成年人的词典里，没有容易二字。 无论你现在是20岁还是70岁，你都可能觉得已经过去的人生里出了一些岔子，其中有的部分无法修补，有的令人懊悔。 你觉得自己选错了专业，跳槽过于频繁，也有可能你正为要不要生孩子而纠结，或正在出轨边缘徘徊。 当你选择了一个方向、一份职业、一种生活方式甚至一个人，也意味着你放弃了其他的可能性。 那些可能性让人着迷，甚至勾引你放弃现有的生活重新来过。 重启毕竟是一个高成本的选择，人生不是一场随时存档读档的游戏，在这之前你需要充分模拟、推演、检查，做好准备再上路。 这本书就是为这样的顾虑而准备的，它写给所有与不可逆的时间搏斗的人。 你能在这里快速学习哲学家如何给不同的事物赋分，表彰它们给予人生的不同价值，看到哲学家如何从自己的中年危机里突围，他们甚至写过多篇论文探讨是不是应该放弃上面提到的其他可能性。 即使你不算改写人生，或者觉得人生过于乏味，这本书也能帮你换种思路，继续生活。

规范性是当代规范伦理学的一个核心观念。本书深探究了人类理性层面的规范性与某种植根于自然化的深层规范性之间的关系，考察了作为元概念/范畴的规范性对一系列相关理论概念、题旨的某种奠基性作用，以展示其解释力及整合力。

本书是一部探讨中国文明起源的著作，作者潜心研究中国历史、哲学和文化多年，力求洞悉中国文明的内在脉络。作者聚焦于中国文明起源过程中的理性要素，通过追溯这个时期理性要素的形态，试图还原中国文明*初的萌发过程。本书沿着中国古代思想观念发展的路，回溯发端，探究这个时期决定历史走向的观念是怎样的，历史是怎样被这种观念所决定的，以及这种观念的来源和后续发展，以此来逐渐揭中国文明起源发展的印记和规律。

《指月录》是明心见性、参禅悟道的典籍。2009年下半年，南怀瑾先生开始带领学人参研《指月录》，并对曹洞宗的特点、学术、修持和传承等方面作了重点研讨，本书即整理自当时的课堂实录，采用对话体。除了原文诵读和白话释义，课堂上以自由发言为主，听讲的学人或提出问题，或表达观点，先生则随时指点、点评。一路讲下来，先生不仅将禅宗的发展、演变脉络讲得非常详尽清晰，对话中更是常常暗藏禅机，如同古时禅师接引学人、对机说法，圣哲言、钵盂语兼而有之。

《参同契》又名《周易参同契》，为东汉魏伯阳著。其学说汇融周易、黄老、丹火之功于一体，用《易》的阴阳变化之理，阐述炼丹、内养之道，证明人与天地、宇宙有同体、同功而异用的法则。??《我说<参同契>》是南怀瑾先生继《论语别裁》后用力*深、*有分量的作品之一，共八十余万言，分上、中、下三册。内容涉及广泛，旁征博引，举证极多，更有南师本人所经历的诸多奇特的人和事，是国人了解、解读《参同契》这部“天书”的选择。

《列子》为道家重要典籍之一，与老庄并列。它高深莫测，易读而难懂，以故事、神话的形态，阐释道家的学术及观念。 《列子臆说》是南怀瑾先生关于《列子》的讲记，共分上中下三册。南怀瑾先生讲述列子，深浅出、生动自在，以《列子》的内容为研究重，带领读者广阔的视野、深难测的奇妙境界，并破了意识的种种局限。列子，这个御风而行的人，要我们从一切自设的框架中突围，成就天地间的自在逍遥。

当今社会，到处洋溢着“透明”的热情，而人们的当务之急是培养一下对距离的热情。 距离和羞耻心无法被纳资本、信息及交际的高速循环。因此，人们便以“透明”的名义消除了所有谨慎的回旋余地。它们被照得通亮，被剥夺殆尽。世界也因此变得更加无耻、更加赤裸。 恰恰于信任不在时，人们对“透明”的呼求声才愈发响亮。在以信任为基础的社会中，人们是不会执意要求透明的。透明社会是一个不信任的、怀疑的社会，由于信任日渐消失，社会便始依赖监控。对透明的大声呼求恰恰表明，社会的道德基础已然脆弱不堪，真诚、正直等道德价值越来越失去意义。 作为一项新的社会命令，透明正在取代日渐式微的道德审查机构。 ------------- 韩炳哲作品系列（见识城邦出品）（已出齐） 《精神政治学》（2019年3月） Psychopolitik 《爱欲之死》（2019年3月） Agonie des Eros 《在群中》（2019年3月） Im Schwarm 《他者的消失》（2019年6月） Die Austreibung des Anderen 《倦怠社会》（2019年6月） Müdigkeitsgesellschaft 《娱乐何为》（2019年6月） Gute Unterhaltung 《暴力拓扑学》（2019年10月） Topologie der Gewalt 《透明社会》（2019年10月） Transparenzgesellschaft 《美的救赎》（2019年10月） Die Errettung des Sch?nen

Learning how to build and program your own robots with the most popular open source robotics programming framework About This Book Get to know the fundamentals of ROS and apply its concepts to real examples Learn how to write robotics applications without getting bogged down in hardware problems Learn to implement best practices in ROS development Who This Book Is For This book is for robotic enthusiasts, researchers and professional robotics engineers who would like to build robot applications using ROS. It gives the robotics beginner and the ROS newbie an immensely practical introduction to robot building and robotics application coding. Basic knowledge of GNU/Linux and the ability to write simple applications is assumed, but no robotics knowledge, practical or theoretical, is needed. What You Will Learn Control a robot without requiring a PhD in robotics Simulate and control a robot arm Control a flying robot Send your robot on an independent mission Learning how to control your own robots with external devices Program applications running on your robot Extend ROS itself Extend ROS with the MATLAB Robotics System Toolbox In Detail ROS is a robust robotics framework that works regardless of hardware architecture or hardware origin. It standardizes most layers of robotics functionality from device drivers to process control and message passing to software package management. But apart from just plain functionality, ROS is a great platform to learn about robotics itself and to simulate, as well as actually build, your first robots. This does not mean that ROS is a platform for students and other beginners; on the contrary, ROS is used all over the robotics industry to implement flying, walking and diving robots, yet implementation is always straightforward, and never dependent on the hardware itself. ROS Robotics has been the standard introduction to ROS for potential professionals and hobbyists alike since the original edition came out; the second edition adds a gradual introduction to all the goodness available with the Kinetic Kame release. By providing you with step-by-step examples including manipulator arms and flying robots, the authors introduce you to the new features. The book is intensely practical, with space given to theory only when absolutely necessary. By the end of this book, you will have hands-on experience on controlling robots with the best possible framework. Style and approach ROS Robotics By Example, Second Edition gives the robotics beginner as well as the ROS newbie an immensely practical introduction to robot building and robotics application coding. ROS translates as "robot operating system"; you will learn how to control a robot via devices and configuration files, but you will also learn how to write robot applications on the foundation of this operating system.

The last of Dickens' picaresque novels which exposes selfishness, portrayed in a satirical fashion using all the members of the Chuzzlewit family. The novel was written after taking a year off during which Charles Dickens visited America. Similarly, young Martin Chuzzlewit, the old man's grandson, goes off to America to live through events which Dickens himself perhaps experienced or observed during his own travels.

Life is not easy in the Soviet Union at mid-20 th century, especially for a factory worker who becomes an unwed mother. But Antonina is lucky to get a room in a communal apartment that she and her little girl share with three elderly women. Glikeria is a daughter of former serfs. Ariadna comes from a wealthy family and speaks French. Yevdokia is illiterate and bitter. All have lost their families, all are deeply traditional, and all become “grannies” to little Suzanna. Only they secretly name her Sofia. And just as secretly they impart to her the history of her country as they experienced it: the Revolution, the early days of the Soviet Union, the blockade and starvation of World War II. The little girl responds by drawing beautiful pictures, but she is mute. If the authorities find out she will be taken from her home and sent to an institution. When Antonina falls desperately ill, the grannies are faced with the reality of losing the little girl they love – a stepfather can be found before it is too late. And for that, they need a miracle.
