This online book provides the best online material I have ever seen on logic, argumentation and critical reasoning. An excellent tool for any serious preacher. At a first glance the book might seem to be a little difficult, but as soon as you start to read everything is explained in detail in an easy to understand manner. It’s possible to download the book in pdf-format.
