From the time of Aristotle's Organon to the 21st century, there is one book on logic that has been studied by more people than any other.
That book is "Introduction to Logic," which was conceived and written with originality by the late Irving Copi (1917-2002), one of the most powerful and sharp thinkers of the 20th century, and which was continuously translated with many supplements and revisions to its content, and was introduced in Korea in the 7th edition in 2007 and the 10th edition in 2010.

This book is the 14th edition of "Introduction to Logic," the latest edition. It is a complete translation from beginning to end to faithfully convey the rich content of "Introduction to Logic" to readers without omission, and it is the first of its kind in Korea.

Humans are born with the ability to reason.
Logic is about learning how to use this ability.
Intuitively, we have long acted according to principles we believe to be reliable, but these are only a small part of what we understand.
These principles can be carefully expressed and precisely stated, and can be confidently applied to problems that can be solved by reason.
By studying logic, people first identify their innate abilities and then learn how to develop those abilities through practice.
Studying logic helps us reason well by revealing the principles of correct reasoning.

By studying logic, people not only reason more carefully, but also think and act more rationally.
I am confident that, through this book, you will develop the fundamental principles of sound reasoning, and this will continue to make a very satisfying and meaningful contribution to your intellectual life.
