For that to be a valid argument, if premises 1 and 2 are true, then the conclusion must
also be true. Is it? Let's see.
Imagine 'A' has nose 'a'. Being a clever sort of chap, 'A' decides he would like to, and has the ability to, replace it with another nose, 'b', which he does. He then asks all of his friends what they think of his new nose. All of them agree that while it is no prettier than his old nose it is no uglier either. In other words, nose 'b' is just as beautiful as nose 'a'. Oddly enough the same turns out to be true of lips 'a' and 'b', eyes 'a' and 'b', etc, etc, etc. In short, the argument is not valid and therefore while it may "seem" logical to you it is not.
Why? Because of a third, implied premise (3.), that only one type of a particular physical feature can be beautiful
. If you can show that to be true, congratulations, you've just earned your DPhil degree. :D
