Hi, everyone! I think you might feel tired when you come to the end of this book. But remember you are not alone. This week (from 16th December to 22nd December) you are going to read from page 91 to 99, Part IV The Sources of Illogical Thinking. Please answer the following three questions. 1.What's the difference between selective skepticism and permanent skepticism? 2.What is evasive agnosticism? What leads to it? 3.Why do we have to exert conscious effort to keep emotion out of argument?
