Week 12 - Post 2: Sign Reasoning

            After reading over the various forms of argument on the instructor’s blog, one of the types of reasoning that I found a bit more difficult to understand was sign reasoning. Upon doing more research on the topic, I found more information on a set of lecture notes from the University of Washington. The notes stated, “Inference says that one thing is a sign of another. It’s usually used in an argument that something is.” In other words, if one thing is present, the other thing is present. For instance, studying for several hours insures that a student will retain information. Furthermore, retaining information insures that the student will do well on their test. When looking at this example as a whole, it is clear to see that the good test score is associated with adequate studying. Without studying, the student would not have gotten such a good test score. Thus, A is only present if B is present. After doing further research, I have a much better understanding of sign reasoning.
