Strong & Valid Arguments

Strong and valid arguments are different from one another.  In a strong argument “with true premises is sometimes better than a valid one with the same conclusion” (Epstein 48). A valid argument means “no possible way for its premises to be true and the conclusion to be false” (Epstein 39). This weather has been really bi-polar. Some days it will be really hot and some days very dark and cloudy. My 4-month-old nephew got sick because one day it was burning up and the next day the temperature dropped 25 degrees. He is not immune to this world yet, and his little bitty body can’t handle it. So for an example of a strong argument would be, Jayden has a temperature of 110 degrees; therefore, Jayden has is sick with a fever. This is a valid argument because there is no way that the premises can be true and its conclusion to be false. An example of a strong argument would be, the doctors took Jayden’s body temperature and it was 110 degrees; therefore, Jayden is sick with a high fever. This is an example of a strong argument because it gives more details and you can prove that it’s true.

  1. I really like your explanation of strong and valid sentences. Good choice of a quote off the book to help support your blog and the meaning of strong and valid arguments. Also, nice job with the example on our whether lately because it totally relates to our current weird whether changes. Just this past two weeks, it went from hot to overcast. Silly whether. Goes to show how we can apply these things to our everyday lives. Also helped me even better understand this concept of the difference between the two arguments in addition to another blog I read from another classmates.

  2. You gave a solid introduction by quoting the definitions of a strong versus a valid argument from the book. I disagree with your valid argument. You explain that the weather was unpredictable and changed drastically from one day to the next which can be plausible but the fact that your nephew became sick is not necessarily caused by the weather change. Your nephew could have gotten sick and mostly like did from catching germs and bacteria from outside or people taking care of him. Therefore your argument is not valid because the weather may be a factor to people's health but it is not scientifically what causes people to become sick.
    But overall you gave a lot of detail in your examples and were clear as to the difference between strong and valid arguments.
