Reasoning by Analogy

After reading through all the different type of reasoning and coming up with real world examples, I found that reasoning by analogy was the hardest to understand. The link that went to wikipedia, gave a definition but it was still more difficult to understand.
After researching reasoning by analogy online I found that basically reasoning by analogy is a statement of a logical statement comparing two similar items or objects.

Can be understood by summarizing it to the argument by analogy can be presented in the form of the equation "A is like B"
In reasoning by analogy, you have to find different and similar characteristics is shared between two or more objects. One with the distinct differences and similarities, you have to make a comparison. The similarities has to be strong enough to stand alone as premises. You then also have to find a principle that covers the two different sides.

  1. This is a good post Donnerz. I like the information you gave to further understand reasoning by analogy. I like how you put in the equation "A is like B". This equation helps further understand and see the analogy between A and B. Seeing the similarities and differences between A and B helps create the analogy between the two. I also like how you added that "the similarities has to be strong enough to stand alone as premises". This I believe is a key point to reasoning by analogy. If the similarities are too far apart, then it will make the reasoning unclear to understand. Then, we would not be able to understand the analogy.

  2. Good blog. After reading through all of the examples of reasons I also had a really hard time trying to figure out what would be some good real world examples I could include in my post. I also looked on wikipedia like you did and was able to find some useful information and references to examples. The example you used, "A is like B," is so classic and right on that it is ridiculous. I have heard this phrase being repeated so many times in my life, and I had no idea what exactly it was that I was listening to. drawing references to two similar similarities is what makes this reasoning work the best.
