Evaluating Analogies

Since I have learned the different types of reasoning’s, a concept that I found interesting was reasoning by analogy. As explained in Epstien’s text, Chapter 12 was about analogies and how we can attempt to analyze and evaluate them. There are questions provided by the text, to use as a guide when we examine an analogy. This is an essential part in our critical thinking course, ensuring that we are on the right path and understanding reasonings. Listed below are the questions in the guide of evaluating analogies.

-Is this an argument? What is the conclusion?
-What is the comparison?
-What are the premises? (one or both sides of the comparison)
-What are the similarities?
-Can we state the similarities as premises and find a general principle that covers the two sides?
-Does the general principle really apply to both sides? Do the differences matter?
-Is the argument strong or valid? Is it good?
