Is it difficult to test the answers in the logic textbook by yourself?
Today, the educational administration teacher collected and sorted out the answers to the self-taught logic textbooks, the answers to related questions about how difficult the self-taught logic is, and the real questions of the self-taught logic over the years and the key materials for reviewing the self-taught logic were downloaded for free. The following are some answers that we have compiled for the national self-taught students, hoping to help your exam!

The answer to the exercises in the general logic textbook for freshmen is generally self-help.

Who has the review questions and detailed answers of general logic? Urgent need, please reply as soon as possible. If you want to study and develop this major, I suggest you read another book. This book itself is very thick, but the content is very professional, comprehensive and systematic, with prominent and detailed points. I am reading Introduction to Concise Logic, which is the most popular logic textbook in America. In 2008, it came out in 10 version, which is likely to replace Kirby's Introduction to Logic. The 10 version has been greatly revised: the introduction of "outstanding logicians" has been added, and the lives and contributions of 14 outstanding logicians in history have been briefly described; At the end of the book, Logic and Postgraduate Entrance Examination has also been completely rewritten and expanded.

Introduction to Concise Logic (version 10) is an introductory logic textbook, which has accomplished three main tasks: First, it has taught students and readers some general knowledge about logic. Including some basic contents of contemporary logic, trying to build an overall image of logic and convey some important concepts about logic. The second is to improve students' or readers' ability to deal with reasoning and argumentation in their daily thinking. Finally, it also pays special attention to the connection between logical content and historical content and social reality content. As the author said, this will help to humanize some cold and blunt logic in the eyes of ordinary people, and it will also be more interesting because of its connection with history, thus increasing its affinity for logic.

Logic is not something in an ivory tower, but something that happens every day in our daily life. The quality of reasoning and argumentation will have a practical impact on our judgment and decision-making in daily life ... Logic is also very important, because it involves the way and efficiency of our thinking and decision-making.

Postscript 569

From February, 2002 to February, 2003, as a sponsor of the American Council for Academic Organizations, the National Academy of Sciences and the Social Science Research Council, I cooperated with the famous philosopher and logician susan haack in the Department of Philosophy of the University of Miami, USA. Of course, there are other tasks in this trip, but I also paid attention to the logic teaching in the United States and listened to some courses in logic and philosophy. I found that there are three main types of logic textbooks in the United States:

Mathematical logic mainly focuses on two kinds of calculus, namely propositional calculus and predicate calculus. In the 1940s and 1970s, there were many such logic textbooks, such as Quine's Logical Methods, Supes's Introduction to Logic and Kirby's Symbolic Logic, but these textbooks were not particularly popular recently.

Introduction to Logic, there are three most successful textbooks in this respect: The first one is Introduction to Logic, another textbook written by Professor Kirby of the Department of Philosophy, University of Hawaii, USA. From the publication of 1953 to the publication of 200 1 to1,it has been widely used for half a century and still belongs to the range of public choice. This book was later translated by Professor Zhang Jianjun of Nanjing University, and included in the Translation Series of Foreign Classical Philosophy Textbooks, which was planned by me and published by Renmin University of China Press, and was published in 2007. The second book is an Introduction to Concise Logic edited by Professor Hurley from the Philosophy Department of the University of San Diego. At that time, there were 8 editions, and recently, there was a 10 edition. At that time, a logic professor at Miami University gave me a copy, telling me that it was a very popular logic textbook in the United States at that time, and it was likely to replace Kirby's Introduction to Logic. The third book is Logic and Philosophy edited by Kahani, a philosophy professor at the University of Maryland. Since the first edition of 1969, eight editions have been published. In 2004, Taiwan Province Shuang Ye Bookstore published a Chinese translation translated by Professor Zhuang, Department of Philosophy, Soochow University.

Critical thinking, which appeared in 1970s, has occupied nearly half of foreign logic teaching. In terms of content, it deliberately downplays the over-technical part, pays attention to the analysis of concrete practice of daily thinking, especially the analysis of reasoning and argumentation in daily thinking, and attaches great importance to the usefulness of logic to daily thinking. Its slogan is "Logic should be related to life and people's daily thinking".

I hope this book is useful to you. To tell the truth, I bought this book in our Xinhua Bookstore at that time. I wanted to buy Kirby's Introduction to Logic, but it was out of stock. Coincidentally, there was a concise logical introduction that day, and there was only one. Unfortunately, I don't have any money in my pocket, but I can't book it. The salesman asked me to pay at least half of the cash, because the price of the book was 78 yuan and it was a very professional textbook. Finally, I made a reservation. The following week, I went to the bookstore and the goods arrived soon. When I opened it, I felt it was too professional, because I had read many textbooks of general logic in domestic universities, even Jin's General Logic, but I had never encountered such a professional and detailed textbook. I was confused at first, because those knowledge points were not at the same level as those in China. . Later, I watched it again and again, and I gradually mastered it. But doing the problem is a challenge, because if you don't understand the theory thoroughly and do the problem 10 to a certain extent, eight mistakes will appear. Among them, I will start taking notes according to my own understanding and the knowledge points in the book. I can do simple and important preparation for the problem. Although I am still teaching myself, I believe that if you are willing to read this book, you will feel the same as me, but you will benefit for life. It is sold on Taobao.

What textbooks are there for self-study accounting? You can have a look at the online self-study exam in your province.

There are detailed introductions about which school will attend this major and which courses this major will attend.

What is "logic"? How to learn logic? Please recommend some good textbooks. The main research object of Popularity is the form of thinking, that is, the logical form of thinking. Our thinking becomes clear because of logic; The so-called "headless case" has to bow before strict logic, so that justice can last forever. Our life can be orderly, and now we have the opportunity to learn logic and learn thinking from it.

Western traditional logic includes conceptual theory, lexical logic and other main contents; Its central content is syllogism; Classical propositional logic; Ancient inductive logic.
