A Class-Room Introduction to Logic

This book is an outcome of my wordpress page "A Class-Room Introduction to Logic" (http: //niyamaklogic.wordpress.com). This was prepared for the students of the paper entitled "Principles of Logic" in the Diploma-in-Reasoning Course of Department of Philosophy, Kurukshetra University, Kurukshetra, where I taught in the Diploma about four years and presently have an experience of teaching logic about 15 years. This book is beneficial for graduate students who have elementary logic course in their syllabus as well as for the general reader of logic. In the Centre for Positive Philosophy and Interdisciplinary Studies (CPPIS), we always tried to create online resources for student's use and published several e-books time to time. We also published print books for reference purpose on philosophy and interdisciplinary studies. This book introduces the basic conceptions of propositional logic and also some part of Symbolic logic in its six sections. Basically I used both printed books and internet sources to prepare it. A list of reference books used to prepare this are mentioned in the end of the book.
