Strong and Valid Arguments


Strong arguments are arguments where the conclusion made is very hard to prove false or wrong. An example of a strong argument than many people deal with on a very regular basis either with themselves, their kids, or their families is being sick with a fever. The premises and the conclusion are always stated like the following argument; if someone has a temperature than they are sick. Albert has a temperature. Therefore, Albert is sick. This is an argument that is stated time and time again by parents and many others. This is an example of a strong argument because almost everyone knows and believes that if you have a temperature than you are sick. It is very hard to come up with reasons for this not to be true. The only way that someone can come up with a way to prove this conclusion false is by using a very implausible and unlikely situation such as: Someone can have a temperature if they had surgery on their brain and the doctors messed up and now their temperature is always high. Although this is a way to prove the conclusion wrong it is a highly unlikely situation. A valid argument is one where there is no way for the premise to be true and the conclusion false. An example of a valid argument is: you must be 16 years of age or older to receive a driver’s license. Therefore I am 16 years or older because I have a drivers license. This is an example of a valid argument because there is no way for it to be false.

  1. I like they way you explained what a valid and a strong argument is. The examples that you used to prove that you have a valid and strong argument really worked well. I like the example where you said, "if someone has a temperature then you are sick." It is quite obvious that if someone had a temperature that they will most likely be sick, so that would conclude that it is a strong argument. Also I liked how you explained the examples after you gave examples. You went further in debt of why you claimed that your argument was strong. Overall, good post in exampling what a strong and valid arguments are.
