Logical Self-Defense

In the early 80's, I took an Informal Logic course as part of my Computer Science training. This book was the text. Over the years, I continually look back to the concepts that I learnt and the way this book presented them. It is within my top 10 list of books that have "changed my life" in that it gave me tools that have never become dated and continue to serve me well. In my present work, we always look at how we can assist people in developing the ability to think critically and "for themselves" -- this book is a must read to that end.
