Any suggestions for good reads on argument theory and how to construct an effective argument (i.e. effective use of evidence, proper use of assumptions, argument structure, argument logic and fallacies, etc)? Bonus points if the book is focused around written arguments. Also, I'm not a PhD on the topic so I'm looking for a book that discusses things in lay terms and is not an academic treatise on the subject. I guess good persuasive writing books would fall into this category. The problem I'm having is that most books are geared towards high school students. I'm looking for something that would be more useful to working professionals, college and graduate students, etc. Thanks.
