CHAPTER 12 Evaluate Your Argument on the Issue
· In this chapter you will learn how to identify and overcome errors in reasoning. This is a special step that applies only to issues because resolving issues involves finding the most reasonable belief. Two broad kinds of errors are examined—errors affecting the truth of your ideas and errors affecting the quality of your reasoning. A step-by-step approach to evaluate arguments is also included.
Because your main objective in addressing an issue is not to find the most effective action but to determine the most reasonable belief, your main task in refining an issue is to evaluate your argument to be sure that it is free of error. Two broad kinds of error must be considered. The first affects the truth of the argument’s premises or assertions. The second affects the argument’s validity—that is, the legitimacy of the reasoning by which the conclusion was reached. A sound argument is both true and valid.
