واقعا شاهکاره این کتاب، شاید بهترین کتاب برای فراگیری مقدماتی منطق باشه. در بخش اول کتاب تمام مفاهیم اساسی منطق بخوبی توضیح داده شده و نحوه آنالیز استدلال ها و تاثیرپذیری استدلال ها از کارکردهای متنوع زبان و برخی مفاهیم زبانی مرتبط تشریح شده. در انتهای این بخش اقسام مغالطات غیر صوری رو بررسی میکنه. فصل مغالطات برای هر کسی فارغ از اینکه به منطق یا فلسفه علاقمنده یا نه، میتونه بسیار مثمر ثمر باشه و تنها فصلی از کتابه که میشه بصورت منفرد و بدون هیچ گونه پیش زمینه ای مطالعه کرد.

بخش دوم کتاب به تشریح واقعا شاهکاره این کتاب، شاید بهترین کتاب برای فراگیری مقدماتی منطق باشه. در بخش اول کتاب تمام مفاهیم اساسی منطق بخوبی توضیح داده شده و نحوه آنالیز استدلال ها و تاثیرپذیری استدلال ها از کارکردهای متنوع زبان و برخی مفاهیم زبانی مرتبط تشریح شده. در انتهای این بخش اقسام مغالطات غیر صوری رو بررسی میکنه. فصل مغالطات برای هر کسی فارغ از اینکه به منطق یا فلسفه علاقمنده یا نه، میتونه بسیار مثمر ثمر باشه و تنها فصلی از کتابه که میشه بصورت منفرد و بدون هیچ گونه پیش زمینه ای مطالعه کرد.

بخش دوم کتاب به تشریح کامل منطق قدیم (قیاسی) و منطق جدید (سمبلیک) میپردازه. توضیحات بسیار ساده و در عین حال بسیار عمیقه! بعضی مسائل که در کتاب های دیگر منطق بصورت گنگ و مبهم ارائه شده با ظرافت خاصی واکاوی شده. در ضمن از پرداخت به مسائلی که نیاز به پیش زمینه ای در ریاضیات داره من جمله اثبات تمامیت و سازگاری منطق جدید خودداری شده.

بخش سوم کتاب به منطق استقرایی و نقش اون در پژوهش های علمی میپردازه که میتونه درآمد بسیار مناسبی به فلسفه علم باشه. احتمالات هم مختصرا در فصل آخر کتاب بررسی شده.

همه ی این نقاط قوت به کنار، مثال ها چیز دیگریست. هر چی از مثال ها بگم کم گفتم. اکثر مثال ها از دعاوی حقوقی، مباحثات سیاسی، کتب فلسفی و ادبی و مجلات و روزنامه ها برگرفته شده. مثال ها باعث میشه که اهمیت منطق در زندگی روزمره کاملا حس بشه ...more

If I could learn formal logic from Copi, and enough to with Hempel and others to critique social statistics for *not* being deductive and using formal logic enough (my Ph.D. stats prof said he never thought formal logic "got you anywhere..."?) than anybody could learn it from this textbook. (Note: you must get older editions of logic textbooks as the newer ones are all watered-down "baby logic" and cover sometimes as little as half the topics as those classes did 30 years ago.) So goes "decision ...more

I read an earlier edition, obviously, because this one was published in 2001 and I read it as the text for a logic class in 1982; however, I still have the book in a handy spot on the shelf, which I can't say about any other book from that year, so it's stayed current and useful - a lot of its content is timeless.
This was a great eye-opener for me; I'd always had a skeptical and questioning way of thinking, but often although I'd have a gut sense that something I was hearing (in a commercial, a ...more

Probably the most universal logic textbook on college campus. It's become a classic at this point. It's hard to justify paying the insane price. Just go for an earlier edition (I used the 9th, which you can find for $2 at amazon, instead of $175). What makes this text unique is its focus on the function of language.

This book introduces several methods of analyzing truth claims about reality and the universe and how to express these truths using mathematical symbols and formulae. I found some of it interesting, especially the section on argument fallacies but some of it seemed rather redundant. Rather how many different ways can we express "if A is true than B is also true" or conversely, "if C is not always true, then D cannot always (or ever) be true; if F is true, then G must be false..." and so on.

Read this as a first-semester senior in college with Dr. Bob Taylor. In a class of 40 or so, I was first in the class all semester, and then on the final exam, I forgot to study an entire section, and I dropped down to second.

I can remember sitting there for a minute after the bell had rung to end the exam hour, and I was stuck on a certain problem. Suddenly it just came to me. I went to Dr. Taylor's office after he had graded them, and I had come up with the correct answer.

Shelves: philosophy

One of the best textbooks, Copi and Cohen don't miss a thing.

It is very difficult though since they use a lot of symbols and formulas for logical structures.

Logic is similar to learning a new language whether Spanish or Coding, it takes a lot of practice, something that the authors provide at the end of each chapter.

This book was also highly praised by Greg Bahnsen, he recommends it in almost all of his courses on philosophy or logic.

Logic: post-structuralism to the contrary, it's what separates "us" from "them."

The book begins with an introduction of the very basic terminology - propositions, premises, and conclusions. It might sound very naive to start this low, but it helped me to refer back to the precise definitions of these words while reading through the rest of the chapters.

Written in plain and simple language, the book covers a breadth of concepts from categorization of fallacies to Venn diagrams to necessary and sufficient conditions. Some of these were new to me while others were a pleasant ...more

this is one of the basic texts of intro logic which has gone thru many editions and iterations.

it covers aristotelian logic completely as well as syllogisms, then covers mathematical logic, then proceeds to the meat of logic, true false tables and making out logic charts from sentences. modal logics and alternate logics are discussed.

logic is very important if you want to think clearly, be a scientist or attorney, or if you want to be any kind of programmer.

I read an earlier version of this book forty years ago and it still impresses me every time I open it. Irving Copi is the best on the market: very thorough, filled with examples, concentrates a lot on ordinary language. A must for writers who want to make strong arguments.

Shelves: filosofía, ucv, lógica, log1, javier-leon, en-papel, leído-parcialmente

Lo que Copi presenta no es sólo una introducción, es un filosofar a martillazos sobre aquellos que desconocíamos todo lo que en estas páginas se explica. Es la piedra en el zapato que, luego de sacarla, resulta ser un diamante. Una herramienta para analizar las argumentaciones de los demás y para formular de mejor forma las nuestras. Aunque, después de todo, lo que buscamos no es la verdad sino la validez.

Lo único que podría criticársele a Copi es que haya colocado la solución de una mínima part ...more

Putting this one aside as it is over-my-head right now. May pick it up again in the middle of the winter when there's not so much other stuff going on and I can focus more....or maybe in a few years when the kids will be ready for it and they can explain it to me.
